This study characterizes the thermal protective fabrics of firefighters’ clothing under the exposure of hot surface contact. For this, thermal protective performance of different fabrics was evaluated using a laboratory-simulated hot surface contact test, and various factors affecting the performance were statistically identified. Additionally, heat transfer mechanisms during testing were analytically and mathematically modeled. It has been found that fabric’s constructional features and properties are the key factors to affect its thermal protective performance. In this study, the presence of a thicker thermal liner in a layered fabric system resulted in higher performance; in contrast, a multi-layered fabric system incorporating a moisture barrier in its outer layer displayed the lowest performance. Furthermore, it was demonstrated that a fabric’s air permeability has a minimal impact on performance, whereas weight, thickness, and thermal resistance have a significant positive impact on performance. Based on the analytical and mathematical models developed, it was apparent that conductive heat transfer mainly occurs through fabric during testing, and this conductive heat transfer depends upon the surface roughness and thermal properties (thermal conductivity, density, and specific heat) of the tested fabric. Here, thermal contact resistance between the hot surface and fabric also plays a crucial role in the heat transfer or thermal protective performance of fabric. Moreover, the heat transfer gradually decreases across fabric thickness, which can substantially affect thermal protective performance. This study can advance the theory of textile/materials science through better understanding of heat transfer in fabrics. This understanding can help in developing an integrated knowledge of fabric properties, heat transfer through fabrics, and thermal protective performance of fabrics. The findings from this study can also assist textile/material engineers with the development of a high performance thermal protective fabric for clothing to provide better occupational safety and health for firefighters.

This study explored the perceptual cognition of differently dyed fabrics among consumers and compared perceptual evaluations of dyed fabrics made of various materials using basic theoretical knowledge of Kansei engineering and clothing materials. SPSS software was used for statistical analysis of the survey data of 100 college students to determine the characteristics of dyed cotton fabric. The results of the perceptual evaluations of plant-dyed and industrial-dyed fabrics are discussed. The most representative characteristics of cotton fabrics, core evaluation vocabulary, and perceptual evaluation factors of plant-dyed and industrial-dyed cotton fabrics were determined by the semantic difference method and cluster analysis. The relationship between the perceptual image word pairs (i.e. vision, touch, smell, health, and value) and each type of dyed fabrics was studied.

Texto completoResumen
One of the most distinctive features of denim is that the warp yarn is dyed with indigo dye and the weft yarns are not dyed, i.e. white. Although warp yarns dyed with indigo dye are woven with different woven fabric weaves, classical denim fabrics weave are produced with 3/1 Z twill weave. The search for new products in denim has led businesses to produce denim-looking knitted fabrics. Denim-looking knitted garments are subjected to industrial washing at the production phase and repetitive household washing processes in daily life. Repeated washing and drying processes cause changes that can affect user satisfaction in terms of losing the colour of the fabric. Therefore, in this study, the colour values of knitted denim fabrics produced as an alternative to denim fabrics manufactured by traditional methods after various industrial (rinse, enzyme and stone washing) and home washes (5, 10, 20 times) were examined. For this, the CIELab colour system was taken as the basis for colour analysis on a spectrophotometer device. As a result of the washing processes performed on each fabric sample (household washing and rinse, enzyme, stone washing applications), it was observed that there were differences in colour values depending on the fibre type, loop yarn length, fabric construction and washing process.

Kapok is a hollow fiber with a 90% hollow degree. Compared with cotton fiber, kapok fiber has excellent performances, such as good hygroscopicity, and a good warmth retention property. In this work, desized indigo kapok/cotton denim fabrics were bleached in different ways: Laser, cellulose enzyme, sodium hypochlorite, potassium permanganate and hydrogen peroxide. After bleaching, the K/S values, tensile strength, air permeability, thickness, color fastness to rubbing and the crease recovery angle of denim fabrics were measured through the spectrophotometer, tensile strength tester, air permeability tester, thickness tester, rubbing fastness tester and fabric crease elasticity tester, respectively. The surfaces of fabrics and fibers were observed by scanning electron microscopy (SEM). Results show that the kapok/cotton fabrics were color-faded after five kinds of bleaching, the K/S values of denim with laser bleaching was declined dramatically, while there was a little change in the permeability. The tensile strength and the weight of the fabrics were decreased, and cloth which was bleached with potassium permanganate was most affected. The color fastness to rubbing and the crease recovery angle of denim fabrics with laser treatment is most suitable for industrial production. In general, laser bleaching is the better way to fade the kapok/cotton denim fabrics. Meanwhile, after five kinds of bleaching, the physical properties of kapok/cotton denim fabrics were similar to those of cotton denim fabric, which indicates that kapok/cotton denim fabric is suitable for the existing industrial bleaching technology.

Texto completoResumen
The publication represents a review of three major types of filter-fabrics which are actively applied by domestic industrial enterprises. It's specially noted that contemporary high-technological manufacturing is impossible without highquality materials. The domestic technologies on filter-fabric production deserve attention unconditionally. Nevertheless, together with modernization of domestic industrial production, the technologies on filter-fabric accumulation have to change also. Namely that's why the functioning of such enterprises, which lean on competitive ability principles, product quality and its high technology, is utterly important now. In this regard, it represents an interest the activity of research-production enterprise Filter-Fabrics (RPE Filter-Fabrics Ltd) where from 2013, there has been started the manufacturing of innovational products which basis on, polyamide mini-thread and filament (complex) thread from high-test polyamide with glass filler which is stable to abrasion and having lower shrinkage during exploitation in the liquid medium. Besides, RPE Filter-Fabrics Ltd has significantly expanded filter-fabric market by the way of correction of thread basis and weft that has allowed to introduce the production on many concentrating factories.

Texto completoResumen
The aim of this study was to determine the pull-out properties of the para-aramid woven fabrics. Para-aramid Kevlar 29® (K29) and Kevlar 129® (K129) woven fabrics were used to conduct the pull-out tests. K29 and K129 woven fabrics had high and low fabric densities, respectively. For this reason, yarn pull-out fixture was developed to test various K29 and K129 fabric sample dimensions. Data generated from single and multiple yarn pull-out tests in various dimensions of K29 and K129 woven fabrics included fabric pull-out forces, yarn crimp extensions in the fabrics, and fabric displacements. Yarn pull-out forces depended on fabric density, fabric sample dimensions, and the number of pulled ends in the fabric. Multiple yarn pull-out force was higher than single yarn pull-out force. Single- and multiple-yarn pull-out forces in K29 (tight fabric) were higher than those of K129 (loose fabric). Yarn crimp extension in K29 and K129 fabrics depended on crimp ratio in the fabrics and fabric density. High crimp ratio fabrics showed high yarn crimp extension compared to that of the low crimp ratio fabrics. Long fabric samples also showed high yarn crimp extension compared to that of the short fabrics. Fabric displacement in K29 and K129 fabrics depended on fabric sample dimensions and the number of pulled yarns. Long fabric samples showed high fabric displacement compared to that of short fabric samples. Fabric displacement from multiple yarn pull-out test was also higher than that of the single yarn pull-out test. It was considered that fabric pull-out properties can play important roles for absorption of impact load due to the yarn frictions in the fabric structures.

Texto completoResumen
The main aim of the study is to present a new innovative method designed by the author of non-destructive, accurate and morphometrical identification of fabric structural parameters, individual inter-thread pores (ITPs) in particular. The description parameters and fabric structure assessment methodology with the use of digital image analysis with author's copyrighted MagFABRIC software were created specifically for this analysis. The ITP parameters were described in three aspects: size, shape and location in the fabric structure. The study was conducted on two groups of fabrics: plain and twill weave. The need for a bimodal analysis of the fabric structure parameters was indicated, as it allowed for the structure differences identification in the test fabrics. The analysis results were compared to the air permeability test. The developed methodology is relevant to specialized fabrics (e.g. barrier fabrics, industrial filters and any other fabric where the ITP area is an important parameter).

Texto completoResumen
Any textiles intended for outdoor usage, particularly in a hot climate with intense sunlight, must be designed and engineered to provide cooling comfort to the wearer. In the case of apparel, clothing creates a microclimate that helps the body maintain its regular thermoregulatory and physiological activities while offering protection against outdoor exposure to UV rays. It is well known that fabrics that absorb significant amounts of solar radiation become inherently hot and feel uncomfortable. This article presents a review of the fundamental radiation interaction mechanisms of fabrics and discusses the key role that fabric structure plays in fabric radiation absorption to determine how cool or hot a fabric will become when exposed to sunlight. A new parameter called the Solar Absorption Index (SAI) is introduced and can be used to characterise the level of coolness (or hotness) of a fabric exposed to solar radiation. The SAI is calculated directly from the fabric’s temperature, ultimately the main factor in determining fabric ability to stay cool. The discussion presented in this article focuses solely on the interaction between solar radiation and fabrics without considering the effects of convection, conduction or any interdependency with the moisture level in the environment.

Wool is one of the most moisture sensitive natural fibers. This paper investigated changes of wool fiber diameter, fabric dimensions and fabric dimensional properties, as a function of moisture regain, temperature and pH. Experiments were conducted on fabrics with different weave structures as well as on fabrics with and without a permanent set. Results showed that the fabrics tended to contract when they were subjected to increased temperature at saturated regain. The degree of contraction appeared to depend on the weave structure of the fabrics and permanent setting treatments. Dimensions of the wool fabrics were also found to be dependent on the pH. Greater fabric dimensions were observed at pH 7.2 than at pH 2.1. The contraction effect was almost reversible when unset fabric samples were measured in pH 2.1. The reasons for the changes of dimensional property were analyzed in terms of changes in wool fiber swelling, yarn crimp and polymer relaxation phenomena with changes in regain, temperature and pH. Industrial implications from outcomes of this research to practical wool processing are discussed in the paper.

Texto completoResumen
The article examines the influence of the surface properties of knitted fabrics from cotton and wool of various knitted structures on the light fastness of their colours. The surface properties of knitted fabrics of single plain, 1×1 rib and French piqué knitted structures were evaluated by determining their roughness using a non-contact optical method for processing digital images of the knitted fabric’s surface. The roughness profiles of the corresponding knitted fabric samples were obtained, and the main indicators of surface roughness were calculated: the profile height at ten points Rz and the arithmetic mean profile deviation Ra . Cotton knitted fabrics were dyed with the Bezaktiv Cosmos dye brand, which are bifunctional reactive dyes with monochlorotriazine / vinyl sulfone active groups, and wool knitted fabrics were dyed with acid dyes. The light fastness of the samples was evaluated after exposure to the Light Fastness Tester (Mercury-Tungsten Lamp) RF 1201 BS (REFOND) with a PCE-TCR 200 colorimeter. Colour measurements were averaged for each sample. Total colour difference (dE) was measured on the dyed cotton knitted fabrics samples after light exposure. According to the obtained roughness profiles of cotton and wool knitted fabrics, it can be concluded that the studied knitted fabrics are characterized by different roughness, which depends on their knitted structures. At the same time, a relationship was found between an increase in the roughness of knitted fabrics and the photodestruction of colours by reactive and acid dyes on cotton and wool knitted fabrics, respectively. The results show that the surface structure of knitted fabrics, that is the knitted structure, impacts the process of colour photodestruction and that the amount of dye that has undergone photodestruction increases with the increasing surface roughness of the knitted fabric.

Ultrasonic technology is widely used to assist many industrial and domestic applications. However, the effect of ultrasonic washing on the thermo-physiological properties of natural based fabrics has not been studied yet. This study aims to examine the relationship between unwashed, ultrasonically washed, and conventionally washed fabrics in terms of their abrasion behavior, flexural rigidity, and comfort properties (thermo physiological). Five specimens of 100% natural based fabrics: linen, bamboo, organic cotton, cotton and wool, were washed using both ultrasonic and conventional methods under a 40°C degree washing temperature. All fabrics were washed ten times for 15, 30, 45 and 60 minutes. No direct correlation between the unwashed and washed fabric abrasion and flexural rigidity properties was observed. Fabric thermal conductivities were changed after the washing processes and in most cases; the ultrasonically washed fabrics had higher conductivity values. It was also observed that lower washing times (15 and 30 min) using the ultrasonic method decreased the thermal resistance of the fabrics. Furthermore, it was also clear, according to the thermal absorptivity results, that the ultrasonic washing method benefited the natural fiber based fabrics. Conventionally washed fabrics were found to have superior water vapor permeability compared to ultrasonically washed fabrics. The ultrasonically washed fabrics have considerably higher heat loss values than the conventionally washed fabrics.

In the present paper, a study of the effects of fabric weight, fiber cross-sectional shapes (round, hollow and trilobal) and presence of reinforcing material on the compression properties (initial thickness, percentage compression, percentage thickness loss and percentage compression resilience) of polyester needle punched industrial nonwoven fabrics is presented. It was found that for fabrics with no reinforcing material, the initial thickness, compression, and thickness loss were higher than fabrics with reinforcing material, irrespective offiber cross-section. Compression resilience data showed the reverse trend. Initial thickness for trilobal cross-sectional fabric sample was highest followed by round and hollow cross-sectioned polyester needle punched fabrics. The polyester fabric made from hollow cross-sectioned fibers showed the least percentage compression at every level of fabric weights. The trilobal cross-sectioned polyester fabric sample showed higher thickness loss followed by round and hollow cross-sectioned polyester fabric samples respectively. The hollow cross-sectioned polyester fabric samples showed maximum compression resilience followed by round and trilobal cross-sectioned polyester samples irrespective of fabric weights. The initial thickness increases, but percentage compression, thickness loss and compression resilience decreases with the increase in fabric weight irrespective of fiber cross-sectional shapes.

Abstract Fabrics coated with rubber have wide applications in fields such as medical substrates, protective clothing, and flexible membranes for civil structures, airbags, geotextiles and industrial fabrics. As the market for coated fabrics expands to applications with more complex geometries and loading conditions, a competitive edge can be gained by optimizing the selection of fabric substrate and coating materials. This work includes a detailed experimental study of the effect of various parameters such as weave pattern, yarn size, and coating thickness on rubber coated fabric mechanical response. Nine types of woven PET fabrics were fabricated, consisting of the same warp yarn size and count, but different fill yarns (220, 500, and 1000 denier) and weave patterns (plain weave, 4-harness satin weave, and 8-harness satin weave). The fabrics were coated with neoprene latex using a dip-coating process. The coating penetration was much greater for the two-ply warp yarns than the fill yarns. Both coated and uncoated fabrics were tested. Shear tests and microscopy were used to understand the interaction between the fabric structure and the rubber coating. Results suggest that the shear behavior of the rubber-coated fabric is dominated by the rubber at low shear angles and by the fabric at higher shear angles. These results improve our ability to predict and prevent undesirable behaviors such as wrinkling, distortion and tear.

Texto completoResumen
This study performs an analysis of steam penetration through thermal protective fabric materials. Different, multilayered thermal protective fabrics were selected and tested in a laboratory-simulated steam exposure, and their steam protective performance (SPP) was measured in terms of the time required to generate second-degree burns on the bodies of wearers. Additionally, the total transmitted thermal energy (TTTE) through the fabrics during testing was measured. Through statistical analysis, it was established that fabric properties, namely air permeability and thickness, are the key factors that affect the SPP and TTTE; the relationship among the fabric properties, SPP, and TTTE is also summarized. Theoretically, it has been found that heat and mass (steam) transfer occur through fabrics in the course of steam exposure, which mainly affect the SPP and TTTE. This study could help textile/materials engineers to develop high performance thermal protective fabrics for the increased occupational health and safety of firefighters and industrial workers.

Texto completoResumen
In this study, stainless steel/viscose blended yarn was prepared and different structured woven fabrics were prepared for studying the moisture transmission and electromagnetic shielding behaviour. By doubling viscose spun yarn with SS filament yarn, the SS/viscose blended yarn was prepared. The woven fabrics were made in a sample loom using viscose yarn and SS/viscose blended yarn. By changing the metal content, thread density and conductive fibre proportions at different levels, the developed fabrics were analyzed for maximum shielding effectiveness in the frequency of 300 kHz to 1.5 GHz. The fabric having conductive threads in warp and weft directions showed larger shielding effectiveness (SE) compared to fabric having conductive threads in one direction. The increase in weft density, proportions of conductive threads (in weft direction) and metal content increases the shielding level of fabric. The highest SE of 56 dB was observed for plain woven fabric compared to 3/1 twill, 2/2 twill and 2/2 basket fabrics in the frequency of 700 MHz. The influence of environmental factors such as relative humidity and pH on shielding behaviour of fabrics were also studied. As the relative humidity was increased, the SE was also increased. The fabric treated with acidic (or) basic condition exhibited better SE than the fabric in neutral condition. Similarly, air permeability and water vapour transmission characteristics of the developed conductive fabrics were also analyzed. The air permeability of the fabric was higher when the metal content in the fabric was low. The fabric having more floats showed higher air permeability compared to fabrics with less floats. Similarly, the water vapour transmission rate was also high for long float fabrics. The developed conductive fabrics could be used as wall covering and personal protective clothing in defense industry.

Purpose The purpose of this paper is to investigate the potential use of the layer-by-layer (LbL) assembly as an intumescent flame retardant for polyester, cotton and their blended fabrics. Design/methodology/approach In this study, polyester (PET), cotton and their blends were applied with the flame retardant coating via the LbL assembly technique. The flame retardancy, melt dripping, thermal properties and morphology of coated polyester fabrics were then examined. Findings The scanning electron micrograph of uncoated and coated fabrics revealed that the LbL assembly coating on the fabric surface was successful. The assessment of the flame retardancy and thermal properties of the coated fabrics showed that the after-flame time and melt dripping during the vertical burning test decreased. The char residue at temperatures ranging from 450 to 800°C during thermogravimetric analysis was enhanced as compared with the uncoated fabric. Furthermore, the morphology of the char residual of coated fabrics was rougher and bulkier than the uncoated fabrics, suggesting the typical behavior of intumescence. Social implications The LbL technique generally uses much fewer chemicals, thus making this flame retardant finishing much more environmentally friendly. It is also expected that these fabrics will show better touch characteristics. These fabrics may be tested for their comfort compared to that of conventional coating to enable their use on an industrial scale. Originality/value This work demonstrated the ability to apply an effective intumescent coating on polyester, cotton and blend fabric. In order to maintain fabric handle property, the Lbl coating technique is also employed.

Resulting from researches conducted to determine tension for para-aramid, meta-aramid, and carbon multifilament yarns during their contact with the operative parts of the weaving looms as part of the industrial fabrics formation process, we have found out that in threading areas the tension is increasing driven by variation of values of the friction forces in the contact area. It has been proven that tension degree of para-aramid, meta-aramid, and carbon multifilament yarns before industrial fabric formation area is influenced by (1) tension before cylindrical guide surface of an operative part, (2) radius of the cylindrical guide surface curve of the operative part, (3) contact angle between yarns and cylindrical guide surface of an operative part, (4) mechanical, physical and structural properties of para-aramid, metaaramid, and carbon multifilament yarns. It allowed (yet at the initial stage of design of technological process of industrial fabric formation) to determine para-aramid, meta-aramid, and carbon multifilament yarns tension before formation area depending on (1) form of threading line for yarns at the weaving loom, (2) mechanical, physical and structural properties of para-aramid, meta-aramid, and carbon multifilament yarns and industrial fabrics. The paper contains experimental research of interaction of para-aramid, metaaramid, and carbon multifilament yarns and cylindrical guide surfaces of the operative parts of automatic weaving looms. Based on experimental researches regression dependencies have been obtained between para-aramid, meta-aramid, and carbon multifilament yarns tension value after cylindrical guide surfaces of the operative part and (1) tension before cylindrical guide surface of the operative part, (2) radius of the cylindrical guide surface curve of the operative part, (3) contact angle between yarns and cylindrical guide surface of the operative part. Consecutive application of these regression dependencies allows to determine para-aramid, meta-aramid, and carbon multifilament yarns tension before industrial fabrics formation area. Analysis of regression dependencies allowed to find out values of technological parameters when para-aramid, meta-aramid, and carbon multifilament yarns tension before industrial fabrics formation area will be of minimum value. It will allow to minimize tension of para-aramid, metaaramid, and carbon multifilament yarns while manufacturing resulting in (1) yarn breakages reduction, (2) better productivity of weaving looms due to reduced stoppage time, (3) improved quality of manufactured industrial fabrics. Therefore, we can argue that suggested technological solutions are practically attractive. In view of this, it is reasonable to say that it is possible to directionally regulate the process of para-aramid, meta-aramid, and carbon multifilament yarns tension change while manufacturing industrial fabrics on the weaving looms through selection of values of guides’ geometrical parameters.

Texto completoResumen
Wrinkling is one of the most common flaws of woven fabrics in domestic use and industrial applications. It is necessary to develop an objective evaluation method to quantify the smoothness appearance of fabrics effectively. Herein, a fabric multi-deformation tester (FMDT) was designed to evaluate the smoothness appearance of garment fabrics by one sequential mechanical test, overcoming the main difficulties of the existing visual measurement methods for wrinkling evaluation of fabrics with complex colors and patterns. The k-means clustering algorithm was used to objectively cluster the fabric samples based on the characteristic parameters, including the wrinkle-induced residual force ( F wr), hysteresis distance ( H fr), position deflection ( D fr) and stretching recovery slope ( S tr), from the testing curve and the thickness and weight of fabrics, and comparisons with subjective evaluation were also conducted. The results reveal that the k-means clustering is able to classify the smoothness appearance of fabrics using the selected characteristic parameters, showing a good consistency with the subjective clustering results.

This study uses 0.08mm copper wire and nickel-coated copper wire as the core and 75 D far infrared filament as the wrapped material to manufacture Cu/FIR-PET wrapped yarn, Ni-Cu/FIR-PET wrapped yarn and Ni-Cu/Cu/FIR-PET wrapped yarn. The three optimum metallic/FIR-PET wrapped yarns are then weaving into Cu/FIR-PET woven fabrics, Ni-Cu/FIR-PET woven fabrics and Ni-Cu/Cu/FIR-PET woven fabrics. Tensile property of metallic/FIR-PET wrapped yarns, electrical resistance of metallic/FIR-PET wrapped yarns, surface resistivity of metallic/FIR-PET woven fabrics and electromagnetic shielding effectiveness of metallic/FIR-PET woven fabric are discussed. According to the results, the optimum tenacity and elongation are chosen as 7 turns/ cm, electrical resistance of Ni-Cu/Cu/FIR-PET wrapped presents the best value, Cu/FIR-PET woven fabric has the lowest surface resistivity and Ni-Cu/Cu/FIR-PET woven fabric shows the best EMSE at 37.61 dB when the laminating-layer number is double layer and laminating at 90 ̊. In this study, three kinds of metallic/FIR-PET woven fabrics are successfully manufactured and looking forward to applying on industrial domains.

The goal of this study is to improve the qualities of Saudi cotton fabrics to be used in a variety of industrial and medicinal applications. Cotton fabrics were treated by dipping in chitosan/ZnO-NPs solutions with various ZnO-NPs concentrations. XRD and SEM of crystal and morphological structure, thermal analysis (TG and DSC) of fabric stability for heat assessment, were used to characterize the fabrics. The produced textiles were tested for antimicrobial activity against Gram-positive Staphylococcus aureus, Gram-negative Escherichia coli (bacteria), and Aspergillus niger, Candida albicans (fungus) using agar diffusion method. According to the XRD data, the fabrics treated with chitosan and by increasing the concentration of ZnO-NPs had increased crystallinity. The successful deposition and strong binding of chitosan and ZnO-NPs to the fabric surface, and the obvious change in fabric morphology, were confirmed by SEM micrographs. The pyrolysis peak positions were changed to a higher temperature. The creation of the inhibitory zone indicated that the treated fabrics had bactericidal effects. The results could be useful in an open innovation approach to improving the qualities of treated textiles that point to their use in medical applications.

Development in technical in textiles especially nonwoven fabrics/materials offers a brightly limitless prospect for the textile industry to lance into an extensive series of applications ranging from earth to space and beyond. Nonwoven industrial wipes fabric properties are the result of production technology and the combination of fabric constructional parameters. This work looks into the effect of fabric parameters on the desired properties of nonwoven industrial wipes fabricated by needle punching technique with the utilization of viscose and polyester fibres and their blends using RSM. The basic and essential characterization techniques to obtain information related to physiochemical properties of the nonwoven fabrics, using analytical investigation techniques have been evaluated. The results obtained established that the fabric parameters have a great influence on the nonwoven fabric structure and ultimately its properties. The result revealed that higher content of PET fibres led to a reduction in the vertical wicking rate, but better rising height can be achieved at samples made from 100 % of viscose fibres. Also, the influence of pore size and porosity largely influenced the fabric characteristics. The fibre volume fraction on the strength of nonwovens has been studied. The fabricated wipes present themselves as potential candidates for highly absorbent industrial wipes.

The rapid progress in the use of textile fabric materials in various industrial and domestic applications requires the inclusion of smart functions to achieve comfortable and safety properties to the end users. However, among these functions is the protection against harmful UV rays that cause harmful effects to human beings and textile materials. To this end, coatings for smart textile fabrics have to be incorporated into textile fabrics. Therefore, in this review, recent advances in the development of coatings for sustainable textile fabrics for UV protection will be reviewed. Hence, the precursors, the synthesis routes and the types of coatings for sustainable textile fabrics will be reviewed. Furthermore, the UV protection action of the coatings for the protection of textile fabrics will be covered and studied. Interestingly, the multifunctional effect of the treated coatings, such as the antibacterial properties of the developed textile fabrics, will be also studied.

This study examined the effects of the fiber materials, fabric structural parameters, and surface modification method on the moisture vapor resistance of coated and laminated fabrics according to the measuring method in comparison with evaporative wet heat transfer method. The moisture vapor resistance (Ref) of the coated and laminated fabrics measured using evaporative wet heat transfer method was much more precise than water vapor transmission rate (WVTR) and water vapor permeability (WVP) measured using American Society for Testing and Materials (ASTM) and Japanese Industrial Standard (JIS) methods. The correlation coefficient between Ref and WVTR in the laminated and coated polyethylene terephthalate (PET) fabric specimens was the highest, i.e., −0.833, and −0.715, in coated fabric specimens. Hence, selecting an appropriate measuring method according to the fabric materials and surface modification method is very critical. According to curvilinear regression analysis, the influential factor affecting breathability of the PET fabric specimens measured using evaporative wet heat transfer method was fabric weight (R2 = 0.847) and fabric thickness (R2 = 0.872) in the laminated fabric specimens. Meanwhile, as per multiple linear regression, the most influential fabric structural parameters affecting the breathability of laminated fabric specimens measured using evaporative wet heat transfer method were the fabric density, weight/thickness, and weight followed by the fabric thickness (R2 = 0.943). These results would be valid for laminated breathable fabrics with characteristics within the range of this study and are of practical use for engineering laminated fabrics with high breathability.

Texto completoResumen
As available energy sources have grown increasingly scarce, people have started paying attention to their energy consumption. Although many methods for power generation are being actively investigated, efficient methods for solving energy problems must be based on reducing energy consumption. Thermal insulation can decrease heat energy loss and conserve energy waste, especially in the construction, transportation and industrial fields. In this study, polyester (PET) hollow fibers were blended with various ratios of low-melting-point PET fibers (10%, 20%, 30%, 40% and 50%). The fibers were blended using opening, carding, laying and needle punching (150 needles/cm2, 225 needles/cm2 and 300 needles/cm2) to prepare PET nonwoven fabrics. The PET nonwoven fabrics were thermally plate pressed (TPP) and air-through bonding (ATB). Thermal conductivity, physical properties and air permeability were investigated to identify the influence of manufacturing parameters on the PET nonwoven fabrics. The experimental results show that needle punching density, TPP and ATB would influence the thermal conductivity of PET nonwoven fabric, because the structure of PET nonwoven fabric was changed. The optimal parameters of PET nonwoven fabric clipped with an aluminum foil was used to evaluate the influence of aluminum foil on thermal conductivity. The PET nonwoven composite in this study can be used in industrial thermal insulation applications.

In this paper, the influence of thermal fixation of woven interlining on the quality of woven fabrics, evaluated from the aspect of their dc volume electrical resistivity, was investigated. The plain weave fabrics made from cotton, flax, viscose, polyester, and cotton/polyester blends and 3/1S twill weave fabric obtained from cotton and polyester fibers blend were investigated. A cotton fabric with a point-applied thermoplastic binder was used as an interlining. The obtained results showed that the dc volume electrical resistivity of fabrics is influenced by their chemical composition, type of weave, type of yarn, fabric density which is especially pronounced in the interlining, the process of thermal fixation of the interlining, and ambient air humidity. The thermal fixation of the woven interlining greatly reduces the dc volume electrical resistivity of polyester fabric (499 times in the warp direction and 860 times in the weft direction), and increases the resistivity of other fabrics in the range of 1.3 times for viscose fabric and fabric obtained from cotton and polyester fibers blend in plain weave to 3.9 times for twill weave fabric. Based on the conducted investigation, it can be concluded that the quality of the tested fabrics evaluated from the aspect of their electrical resistivities, was significantly improved in the case of polyester fabric i.e worsens in the other investigated fabrics after thermal fixation of the woven interlining.

Texto completoResumen
Roller blind fabrics are preferred and commonly used in home and office. In general, these fabrics are produced by coating the acrylic blended material, which is known by their ultraviolet properties, onto polyester woven fabrics. In this study, in order to characterize the sound insulation properties of roller blind fabrics, coating resin having different ratios of acrylic are applied onto different polyester woven structures. Sound absorption properties of these fabrics (front and back sides) are measured through dual microphone impedance tube and investigated by statistical analyses. Regression curves are obtained and optimum fabric properties on sound absorbing property have been suggested. As a result, acrylic content in coating material, fabric type, and viol structures occurred by coating process on the woven fabric are found as effective parameters on sound absorption properties of these fabrics. Increasing acrylic content in the resin up to 40% increases the sound absorbing value but further increasing this ratio yields sound reflection from the structure, in general. Optimum sound absorption and reflection values are provided with 40% acrylic rate in coating mixture.

Texto completoResumen
Structural parameters of fabrics influence the mechanical behaviour of fabric-reinforced composites. Weft-knitted spacer fabrics have high energy absorption capacity. In this paper, low-velocity impact behavior of composites reinforced with weft-knitted spacer fabrics has been studied using energy-balance method. The effect of fabric geometry on the impact behavior of composites was investigated. A theoretical model was generated to predict the energy dissipated through the impact, considering the structural parameters of fabrics as reinforcement of composites. For this purpose, dissipated energies due to contact, membrane and bending deformation of fabrics, and buckling deformation of spacer yarns were considered. In order to evaluate the proposed model, weft-knitted spacer fabrics with two types of spacer yarn's orientation were used as reinforcement of composites. Low-velocity impact examinations were performed using the drop hammer testing machine. The results showed that the model has about 12 and 13% error in prediction of dissipated energies of different samples. Comparison between theoretical and experimental results confirms that the proposed model is capable to predict the impact behavior of weft-knitted spacer fabric-reinforced composites.

The water, air permeability and thermal resistance of fabrics are important attributes that have a significant impact on the thermal comfort properties of sportswear fabrics in different environmental conditions. In this work, terry and fleece fabrics were developed by varying the fibre content and mass per unit area of fabrics. Moreover, the thermo-physical properties of the developed fabrics, including air permeability, water vapor permeability and thermal resistance, were analysed before and after washing. The multi-response optimization of the thermal comfort properties of knitted fabrics was performed using principal component analysis (PCA) and the Taguchi signal-to-noise ratio (PCA-S/N ratio) to achieve optimal properties. It was determined that the selected parameters (fabric type, finishing, fibre content and fabric mass per unit area) had a significant effect on the thermal comfort properties of knitted fabrics. The PCA analysis showed that 100% cotton terry fabric before washing with an aerial weight of 220 g/m2 had higher air and water vapor permeability value, but a lower thermal resistance value.

The main purpose of this study was to evaluate the ultraviolet protective factor (UPF) of fabrics coated with titanium-based metal-organic framework (MOFs) (NH2-MIL-125(Ti)) made using an In-situ synthesis method and more accurately assess the intrinsic properties of the fabric. The cotton-polyester twill fabric (70-30%) (246.67 g/m2) was coated. In-situ coating conducted in 4 steps washing the fabrics, preparation of MOFs, injecting the MOFs to fabrics, and drying the fabric after coating. The scanning electron microscope (SEM), FTIR spectrometer, dynamic light scattering (DLS) and UV-Vis spectrophotometer were used to analyses the data of coating and UPF results. Also, four standards such as ASTM D737, ISIRI 8332, ISIRI 4199, and ISIRI 567 were used for analyzing the intrinsic properties of the fabric. The results of SEM and DLS altogether confirmed the in-situ formation of MOFs onto the fabric fibers. Moreover, the UPF value of the uncoated and coated fabrics was 3.67 and 315.73, respectively. It was showed that the in-situ deposition of NH2-MIL-125(Ti) on fabric can provide adequate protection against UVR. Also, the results of analyzing the intrinsic properties of the fabric showed that there was no significant difference in the intrinsic properties between the coated and uncoated fabrics. Based on the results, it can be concluded that the UV protective property of workwear fabrics can be improved by coating NH2-MIL-125(Ti) on them without any effect on the cooling effect of perspiration evaporation.

This research focused on the thermal comfort behaviour of polyester with respect to the type of yarn (spun, micro denier, continuous filament and hollow), linear density of the yarn (111 and 166 dtex), and the loop length of knitted fabric (0.25, 0.27 and 0.29 cm).The air permeability of continuous filament yarn fabric and micro denier yarn knitted fabrics was noted to be higher than that of spun yarn knitted fabrics. 111 dtex micro denier yarn fabric has the highest air permeability and 111 dtex spun yarn fabric the lowest air permeability value among all the other fabric samples. Comparatively, coarser spun yarn fabric has lower air permeability characteristics than finer microdenier fabric.The water permeability of the fabric shows a significant difference between the spun yarn, continuous filament yarn and Micro denier yarn knitted fabrics and between the linear density of the yarn. The water vapour permeability of spun yarn of 166 dtex single jersey fabric is higher, while the water vapour permeability of continuous filament yarn fabric of 166 dtex is lower. The thermal conductivity value is high for continuous filament polyester fabric of 100 D and low for microdenier polyester fabric of 166 dtex. Based on the statistical analysis, it is clearly shown that there are significant differences between the three different polyester yarn fabrics of two different denier of the same fabric. Furthermore, the count and different polyester yarn affect the comfort properties of single jersey fabrics.

Polypropylene (PP) spunbond nonwoven fabrics are very important especially for health, furniture, and household industries. These industrial applications require fabrics with high tensile strength properties. In the textile industry, Digital Image Analysis (DIA) is used commonly on fabric property determination and online controlling. The estimation of fabric weight using digital image analysis is well established in the literature. But limited information can be found about the prediction of grab tensile strength and elongation at break using Digital Image Analysis (DIA). In this study, DIA and Artificial Neural Network (ANN) are used for the prediction of areal weight, tensile strength and elongation at break values of PP nonwoven fabrics at various weights (12g/m2, 20g/m2, 25g/m2, 30g/m2, 50g/m2). The experimentally tested fabric properties and the numerical defined statistical parameters obtained from DIA are related with each other using ANN. Results show that ANN is capable of prediction of fabric material properties by using data obtained by DIA without any experiments for the investigated type of PP nonwovens.

Breathable layered waterproof fabrics have good applications in the fields of sportswear, protective clothing and construction industries. The properties of these fabrics in allowing water vapour to pass through while preventing liquid water from entering have made them unique. The mechanical properties of these fabrics are also very important for the satisfaction of the wearers. The layered constructions of these fabrics with different characteristic properties contribute to the influence on their hydrostatic resistance, mechanical properties and water vapour permeability. This study presents an experiment on eight different types of hydrophobic and hydrophilic membrane laminated layered fabrics used as sportswear during hot or cold weather. The hydrostatic resistance, tensile strength, stiffness and water vapour permeability of these fabrics were evaluated by varying different fabric parameters in the experiment. It was found from the test results that the fabric density, thickness and weight as well as types of membranes and layers have a significant effect on those properties of the layered fabrics.

The investigation of thermal protective performance of fabrics is highly relevant in order to procure and further develop the firefighters' protective clothing. Therefore, this paper aims at investigating the thermal protective performance of fabrics used in firefighters' clothing under different levels of radiant-heat exposures. For this, properties of a set of thermal protective single- and multi-layered fabrics were measured, and these fabrics were tested under radiant-heat exposures using the Method B of ISO 6942:2002 standard. During the testing, fabrics were exposed to low (10 kW/m2), medium (40 kW/m2), and high (80 kW/m2) intensity radiant-heat exposures; and the heat transfer level (i.e., time required to increase the skin temperature of a wearer/firefighter by certain degrees) through these fabrics were calculated to measure their thermal protective performance. The effects of fabric parameters, structures, properties, and radiant-heat intensities on the protective performance were characterized, and fabric properties that significantly affected the protective performance were statistically identified at different level of radiant-heat exposures. It has been found that weight, thickness, thermal resistance, and evaporative resistance can positively affect the protective performance. Also, the significant fabric properties affecting the protective performance vary for single- and multi-layered fabrics. By using these significant properties, the protective performance of single- and multi-layered fabrics were also separately predicted by mathematical models, i.e., multiple linear regression models and multiple logarithmic regression models. As per the findings of this study, multiple linear regression models can effectively be used to predict the thermal protective performance of fabrics. This study will lead towards building a better understanding and prediction of thermal protective performance of fabrics under radiant-heat exposures.

The plate compression property of warp-knitted spacer fabrics greatly determines their industrial application in cushions and mattresses, which can be regulated by the structure and property of spacer filaments of spacer fabrics. To better meet application requirements, this paper detailed a study on the relationships between the geometry and property parameters of spacer filaments and the plate compression property of spacer fabrics. A three-dimensional structure model was firstly developed using the finite element method based on a typical spacer fabric. The model shows a satisfactory prediction of the compression force–strain curve of the spacer fabric compared with the corresponding experimental curve. Consequently, the effects of geometry parameters, including height, diameter, arrangement density and bending angle of spacer filaments, and Young’s modulus of the filaments on the compression behavior of spacer fabrics were investigated using the validated model by adjusting the corresponding geometry and property parameters. The stress nephogram and stress distribution along the filaments at compression strain 0.6 were analyzed to discover the deformation mechanism of spacer filaments under compression. It was found that the spacer fabric with smaller filament height, courser filament diameter, larger bending angle, higher arrangement density and Young’s modulus of filaments had higher compression resistance. This study is useful to optimize the performance of spacer fabrics in design and manufacturing by purposefully tuning the geometry and property parameters.

Lead-shielding products, such as lead aprons, are important materials for personal protection of physicians and patients from X-ray (gamma) radiation during medical operations. However, lead has environmental disadvantages such as high toxicity. The aim of this study was to manufacture an environmentally friendly and flexible textile-based radiation shielding material. In this work, 3/1 twill and some cellular woven fabrics were produced with conductive core yarns, and gamma radiation shielding effectiveness of these cellular woven fabrics were investigated and compared with that of the 3/1 twill woven fabric, which are commonly used as uniforms and were not studied previously in any other literature. The effects of weave on the structural characteristics of fabric such as the conductive weft yarn density, fabric thickness, and fullness were analyzed graphically and statistically. It is observed that with indenting and protruding, structure cellular woven fabrics performed better gamma radiation shielding performance than the 3/1 twill woven fabrics. The sample B1, woven with cellular weave 1, has the highest gamma radiation shielding effectiveness, thanks to the highest fabric thickness. In addition, the increase in the conductive core yarn density improved the gamma radiation shielding effectiveness of the woven fabrics.

In this study, the application of textile fabrics coated with biodegradable bioactive alginate film was investigated, which was obtained from natural polysaccharides such as sodium alginate extracted from sargassum wightii and padina tetrastromatica seaweeds. The functional groups present in the bioactive substances of alginate film coated fabrics was assessed using Fourier transform infrared spectroscopy, and the antioxidant and antibacterial properties of alginate film coated fabrics were assessed using DPPH free radical scavenging and EN ISO 20645 test methods, respectively. The effect of coatings on biomaterials was evaluated using field-emission scanning electron microscopy, and the effect of alginate film coated fabrics on comfort properties such as thickness, air permeability, wickability, flexural stiffness, and wettability was studied. The experimental result specifies that the maximum antioxidant activity of 54 ± 0.98% inhibition was achieved and maximum antibacterial activity was attained with the inhibition zone of 44 mm in alginate film coated textile fabrics. The air permeability, flexural stiffness, wettability, and wickability properties were slightly affected in both coated textile fabrics compared with uncoated fabric. The sargassum wightii alginate film coated textile fabric showed 80% of wound healing activity compared with padina tetrastromatica alginate film coated textile fabric. This alginate film coated textile fabrics are preferably suitable for nonimplantable materials such as wound healing, skin grafts, food industry, pharmaceutical industry, and hygienic textiles.

Texto completoResumen
Fabrics treated to repel water, superhydrophobic, and water and oil, superamphiphobic, have numerous industrial and consumer-level benefits. However, the liquid repellency decreases in the course of time. This is largely due to chemical or physical changes of the coating due to prolonged exposure to relatively harsh environments. To develop more durable fabric treatments for specific applications, it is necessary to measure the extent to which the treated fabrics retain their low-wettability after being subjected to controlled aggressive environmental conditions. In this study, plain weave fabrics made from polyester filaments and coated with silicone nanofilaments in-solution were exposed to aerodynamic icing conditions. The coated fabrics showed superhydrophobic behavior, or superamphiphobic for those that were fluorinated. The wettability of the fabrics was progressively evaluated by contact angle and roll-off-angle measurements. The coated fabrics were able to maintain their low-wettability characteristics after exposure to water droplet clouds at airspeeds up to 120 m/s, despite damage to the silicone nanofilaments, visible through scanning electron microscopy.

In this research, eight different 3D weft-knitted fabrics were developed and evaluated. 3D fabrics have been knitted on circular weft-knitting machines with two different gauges: 20E gauge and 28E gauge. Three different raw materials were used for the fabric’s production: high molecular mass polyethylene (HPPE) yarn and 0.05 mm diameter steel wire in the outer layers (for the front and reverse) and polyamide yarn in the binding layer. The experiments were conducted on the developed 3D knitted fabrics to determine the fabric’s resistance to mechanical risks such as circular blade cut, puncture, abrasion, and also to evaluate the comfort parameter, such as air permeability. It was defined that 3D weft-knitted fabrics best results on tests: circular blade cut, puncture and abrasion resistant were achieved using HPPE yarn twisted with steel wire, higher mass per unit area with more significant amount of steel wire. According to the standard EN 388:2003, three samples of developed 3D weft-knitted fabrics had the highest 5th blade cut and the highest (4th) abrasion resistance level. All of them had the highest (4th) level of puncture resistance. 3D fabrics knitted on a circular weft-knitting machine of gauge 28E ensured 1.3–2.1 times greater blade cut and 4.9–12.1 times greater abrasion resistance result, than fabrics knitted on gauge 20E, due to a higher stitch density, higher mass per unit area, density and fabric’s thickness. But on the other hand, these parameters lowered air permeability by 20.2–43.0%.

To minimize the serious defects of durable press finishing of cellulosic textiles with respect to the great loss in strength properties, new pioneering strengthening approach of cotton fabric based on our previously prepared starch nanoparticles of size around 80–100 nm was used. For this purpose, cotton fabrics were treated with different concentrations of starch nanoparticles via coating technique using pad-dry-cure method, at which the starch nanoparticles are attached to the fabrics with the use of a padder adjusted to appropriate pressure and speed, followed by drying and curing. Fabric stiffness, surface roughness, tensile strength, elongation at break, abrasion resistance, wrinkle recovery angles, add-on %, and degree of whiteness as well as durability of treated fabrics were fully explored. SEM was used for detecting the change in surface morphology of reinforced coated fabric. The results obtained reflect the following findings: (a) all fabric performance like tensile strength, stiffness, wrinkle recovery angle, abrasion resistance and add on % were improved for coated fabrics with starch nanoparticles in comparison with untreated fabric, except that of surface roughness; (b) SEM confirmed the change in surface morphology of cotton fabric after reinforcement treatment using starch nanoparticles; (c) the dry wrinkle recovery angle and tensile strength of cotton fabrics treated in presence of 30 g/l starch nanoparticles are slightly decreased after 10 washing cycles as compared with untreated fabric; and (d) starch nanoparticles introduce an advance in textile finishing with respect to the above-mention fabric performance except that of surface roughness.

This work evaluates the feasibility to manufacture polylactic acid (PLA) composites using jute fiber fabrics. For characterization, PLA-fused filament was successfully deposed onto jute fabrics to print dog-bone tensile specimens (Type I specimen from ASTM D638). The jute fabrics were chemically modified, treated with flame retardant additives, and sprayed with aerosol adhesive to improve the mechanical properties of PLA/Jute fabric composites. The elastic modulus and the strength of PLA were higher than PLA composites, and the plastic deformation of the PLA composites was slightly lower than PLA. Tomography scans revealed the fabrics were well oriented and some adherence between jute fabrics and PLA. Viscoelastic properties of PLA composites resulted in the reduction in storage modulus and the reduction in intensity in the damping factor attributed to segmental motions with no variations in the glass transition temperature. Flame retardant and spray adhesive on jute fabrics promoted better response to time of burning than PLA and PLA with modified fibers. The results presented in this work lead to the need for a more detailed investigation of the effect of plant fiber fabrics as reinforcement of 3D printed objects for industrial applications.

The loop transfer technique was used to develop the a splitable multi layer knit fabric on a computerized multi gauge flat knitting machine. The fabric consists of three layers: inner-single jersey, middle-1×1 purl and, outer-single jersey. By varying the loop length the multi layer knit fabric samples were produced, namely CCC-1, CCC-2 and CCC-3. The above multi layer fabrics were knitted using 24s Ne cotton of combined yarn feed in feeders 3, 4, and 4 respectively. The influence of loop length on wpc, cpc and tightness factor was studied using linear regression. The water vapor and air permeability properties of the produced multi layer knit fabrics were studied using ANOVA. The change of raw material in three individual layers could be useful for the production of fabric for functional, technical, and industrial applications.

In this study, it is aimed to change the loop length of knitted fabrics with a mesh structure and to investigate the effect of loop length differences on thermal and moisture transmission properties. For this purpose, six fabrics with different loop lengths were produced in two different knittings and yarn types. Thermal conductivity, thermal absorptivity, thermal resistance, air permeability and moisture management properties of these fabrics were measured according to standard test methods. The results showed that as the yarn gets finer and loop length increases, the air permeability values will increase. It was observed that as the loop length increase, the overall moisture management capacity (OMMC) and thermal absorptivity of the fabrics will decrease. The thermal resistance values of two ply textured polyester mesh knitted fabrics decreased with increasing density and the highest loop length two ply textured polyester mesh knitted fabric showed the highest thermal resistance value.

Laser treatment is a high-efficiency coating process with many advantages of stable performance, convenient operation and environmental friendly. In this study, an efficient method for the pretreatment of polyester fabric, based on exposure to the output from a CO2 laser, is investigated. Polyester fabrics were treated by laser and then copper films were coated on the surface of treated polyester fabrics by magnetron sputtering method. Copper-coated polyester fabrics were characterized by XRD and SEM. Contact angle, heat generation and electrical conductivity of copper coated polyester fabric were tested. The electrical conductivity, UPF value and contact angle of copper-coated polyester fabric with pretreatment of 6.5 W lasers are 0.239 Ω/sq, 147.4, and 128.5°, respectively. The temperature of copper-coated fabric can be kept at 25.8℃ using only 5 V. The results suggest that the copper-coated polyester fabric with pretreatment of laser has excellent electrical conductive property, hydrophobicity, UV blocking, and heat generation properties. The adhesion strength between copper coating and fibers is improved after laser treatment. Laser can be potentially used in pretreatment of fabrics before coating in the future.
