Abstract:

In this paper, the surface area of coated polymer-based textiles, i.e., copper and nickel plated woven polyester fabric, copper and acrylic coated woven polyester fabric, and copper and acrylic coated non-woven polyamide fabric, is investigated. In order to evaluate the surface area of the woven fabrics, Peirce’s geometrical model of the interlacing point and measurement using an electron microscope are used. Non-woven fabrics are evaluated using an optical method, handmade method, and MATLAB functions. An electrochemical method, based on the measurement of the resistance between two electrodes, is used for relative comparison of the effective surface area of the coated woven and non-woven fabrics. The experimental results show that the measured and calculated warp lengths do not differ within the standard deviation. The model for the surface area evaluation of the Pierce’s geometrical model for monofilament (non-fibrous) yarns is extended to multifilament yarns and to a uniform sample size. The experimental results show the increasing trend of surface area evaluation using both modeling and electrochemical methods, i.e., the surface area of the copper and acrylic coated woven Polyester fabric (PES) is the smallest surface area of investigated samples, followed by the surface area of the copper and acrylic coated non-woven fabric, and by copper and nickel plated woven PES fabric. These methods can be used for surface area evaluation of coated polymer-based textiles in the development of supercapacitors, electrochemical cells, or electrochemical catalysts.

Abstract:

Coated fabrics have complex composite structure whose mechanical properties are considerably improved in relation with the initial basic material. They are obtained by applying a certain number of coatings to raw fabrics. In this paper the practical application of uniaxial testing of coated fabrics for determining its breaking properties and Poisson’s ratio is presented. Due to the anisotropy of woven and coated fabrics, Poisson's ratio changes over the fabric sample stretching. Experimental testing were carried out on two samples of plain weave cotton fabrics. The fabrics were tested before coating, and after one, two and three coatings. Samples are stretched with tensile force in the weft and warp direction, and based on different measured values of fabric stretching, warp and weft Poisson's ratio is calculated. The values of tensile force and relative extension of coated fabrics were measured, and breaking force values, elongation at break, contractions at break.

Abstract:

Due to its excellent performance, special style and variable function, coated fabric is used more and more widely by the public. At present, there are lots of coated fabrics, most of which are made from woven fabric, knits are rarely used. The reason is knitted fabric has good elasticity and large deformation. Therefore, it is difficult to control the tension in the direct coating process. In this paper, the transfer coating process is adopted to solve this problem. First of all, knitted fabric was finished by padding flame retardant, then coated with polyurethane(PU) which includes flame retardant. The optimum transfer coating process is obtained by orthogonal experiment. Knitted coated fabrics with flame retardancy are manufactured by the optimum coating process. Washing durability of coated fabric was tested through the washing test. The results showed that the coated fabric has good flame retardancy and the washing durability.

Abstract:

Electromagnetic radiation of telecommunication is undesired in rooms for data privacy [1]. One way to shield EM radiation is by achieving textile fabrics with electrical conductive properties [2,3]. Buildtech technical textiles are used in constructions and as such they need fireproof properties, too. Magnetron plasma sputtering is a novel technique for rendering nanometer scale coatings on woven fabrics. It is an eco-friendly technique, which leaves the bulk properties of the fabric unaltered and modifies only the surface properties. Thus, textile EM shields out of magnetron plasma coated fabrics keep initial properties of textile materials, such as flexibility, light weight, 3D shape-ability, good mechanical resistance and receive as well novel functionalities. The ERA-NET Manunet TexEMFiRe project aims to research Buildtech technical fabrics with electromagnetic shielding and fireproof properties, made out of magnetron plasma coating. TexEMFire envisages an optimization of plasma coated fabrics based on fabric structure parameters (density) and plasma coating parameters (generator power) The project has duration of two years (Apr. 2018-Mar. 2020) and five partners: INFLPR, INCDTP, Majutex from Romania and UniUPO and TecnoLab from Italy.

Abstract:

Properties of woven fabrics used to make airbag cushions are influenced by a lot of factors: the nature of raw materials, woven fabric geometry and density, technological parameters of the weaving operation and finishing. The main purpose of this research paper is to find the values of three mechanical parameters – tensile strain, tensile stress and specific modulus – according to the type of samples and test direction on the testing stand. To obtain woven fabric samples were used polyamide 6-6 polyfilament yarns (nylon), silicone coated and uncoated fabric. Testing procedure and samples preparation were done following the standard EN ISO 13934-1:1999. Test results and graphs show that, we have a good uniformity of the geometry for the analyzed fabrics.

Abstract:

Soft tissue defects in the oral maxillofacial area are critical problems for many patients and, in some cases, patients require an operation coupled with a performance scaffold substitution. In this research, mimicked anatomical scaffolds were constructed using gelatin- and chitosan-coated woven silk fibroin fabric. The morphologies, crystals, and structures were observed and then characterized using scanning electron microscopy, X-ray diffraction, and differential scanning calorimetry, respectively. Physical performance was evaluated from the swelling behavior, mechanical properties, and biodegradation, while the biological performance was tested with fibroblasts and keratinocytes, after which cell proliferation, viability, and histology were evaluated. The results revealed that a coated woven silk fibroin fabric displayed a crystal structure of silk fibroin with amorphous gelatin and chitosan layers. Also, the coated fabrics contained residual water within their structure. The physical performance of the coated woven silk fibroin fabric with gelatin showed suitable swelling behavior and mechanical properties along with acceptable biodegradation for insertion at a defect site. The biological performances including cell proliferation, viability, and histology were suitable for soft tissue reconstruction at the defect sites. Finally, the results demonstrated that mimicked anatomical scaffolds based on a gelatin layer on woven silk fibroin fabric had the functionality that was promising for soft tissue construction in oral maxillofacial defect.

Abstract:

Polyurethane-coated knitted fabrics are of interest because they exhibit several positive properties, they are more stretchable, elastic and comfortable than coated woven fabrics and yet they are little studied. Information of weather durability, as well as thermal properties, is essential to ensure thermal protection for textile materials intended for outdoor use. In the presented research, a series of coated knitted fabrics for protective clothing were developed and exposed to weathering in summer and winter seasons. After three months of outdoor exposure, thermal resistance of all the tested materials decreased by 13% after the summer season and 25% after the winter season. A very good correlation of knitted fabric mass per unit area and thermal resistance of knitted fabric, coated fabric and aged coated fabric occurred. The studied materials experienced a partial degradation of the polyurethane layer, which is not related to the deterioration of the knitted substrate. The presented investigation of thermal resistance of coated fabrics and their dependence on the knitted substrate, as well as the influence of environmental conditions, allows the improvement of coated fabrics with the aim of better thermal protection.

Abstract:

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.

Abstract:

Manifold variations of the mechanical behavior of structural woven fabrics appear in the first load cycles. Nevertheless, invariable states, i.e., mechanically saturated states, can be approached by multiple monotonous load cycle biaxial tests. In a state acceptably close to the ideal saturated state, the stress–strain paths reveal the elastic share of the initially inelastic stress–strain paths of woven fabrics. In this paper, the mechanical saturation behavior of two types of PTFE-coated woven glass fiber fabrics is examined and compared to the recently reported saturation behavior of a PVC-coated polyester fabric. With the help of the saturation test data, an extrapolation function is developed that facilitates an estimation of late cycle stiffness behavior based on measured early cycle behavior. Furthermore, the considerable impact of late cycle properties on structural analyses is shown exemplarily in the numerical simulation of a prestressed fabric structure by comparing results achieved from late and early load cycle stiffness parameters.

Abstract:

This study presents the results of laboratory experiments to prepare cotton woven fabrics with photoactive properties. The fabric was treated with TiO 2 – Fe(1%) – N + 2% graphene by exhaustion followed by a fluorocarbon polymer treatment. The fabric was analyzed by Scanning Electron Microscope coupled with Energy Dispersive Spectroscopy (SEM/EDAX), Differential scanning calorimetry (DSC), Contact Angle measurement, physical properties (weight, thickness, breaking strength, elongation, air/water permeability, electrical resistance). The photocatalytic activity was determined initially and after 5 washings by measuring the trichromatic coordinates of the treated fabrics stained with methylene blue and exposed to UV and visible light on a Hunterlab UV-Vis spectrophotometer. The results demonstrate a uniform deposition of doped TiO 2 -graphene particles on material surface. The thermal stability of the coated cotton fabric is practically unmodified in comparison with blank cotton fabric. The decrease of the surface resistivity demonstrates the deposition of graphene layer, known for its good electrical conductivity. The wetting capacity of initial hydrophilic cotton fabric is dramatically modified, the fabric becoming hydrophobic after treatment. The photocatalytic efficiency is higher under visible light than under UV-radiation due to the TiO 2 doping and decoration with graphene, which extend the light absorption from UV to visible range. The good photocatalytic activity under visible light is maintained after 5 washing cycles.

Abstract:

Abstract The portable and wearable instrumented fabrics capable of measuring biothermal variable is essential for drivers, especially long-distance drivers. Here we report on portable and wearable devices that are able to read the temperature of human body within the woven fabric. The sensory function of the fabric is achieved by temperature sensors, soldered on conductive threads coated with cotton. The presence of stainless steel wires gives these materials conductive properties, enabling the detection of human body temperature and transmitting the signal form sensors to the motors on the fabric. When body temperature decreases, hardware/software platforms send a signal to the vibration motors in order to stimulate the driver. The ‘smart woven fabric’-sensing architecture can be divided into two parts: a textile platform, where portable and wearable devices acquire thermal signals, and hardware/software platforms, to which a sensor sends the acquired data, which send the signals to the vibration motors.

Abstract:

In this paper, the compound hot-melt adhesives were prepared by blending alkyl sulfonate polymer antistatic agent with modified rosin hot-melt adhesive and used for the preparation of polyethylene film/polypropylene-coated non-woven fabrics. The effects of the amount of antistatic agent on the melt viscosity, softening point, and thermal stability of the compounded hot-melt adhesives were studied. Then, the antistatic properties and its washing fastness of the coated non-woven fabrics were tested and analyzed. The results showed that the softening point and the melt viscosity of the hot-melt adhesives decreased after compounding, and the thermal stability of the compound hot-melt adhesives decreased in the high temperature range, which was not affected before 200℃. The surface inductive voltage, half-life, and specific resistance of the coated non-woven fabrics prepared from the compound adhesives decreased gradually with the increase of the amount of the antistatic agent, indicating that the antistatic property of the prepared fabrics was gradually improved. In addition, the fabrics still exhibited antistatic properties after soaping for several times. The influence of compound adhesive on the wettability of fabric surface was consistent with that of antistatic property. Finally, the mechanism of the hot-melt adhesive and antistatic agent compounding technology to improve the antistatic performance of the coated non-woven fabrics was elaborated, and the reason for its excellent soaping durability was also explained.

Abstract:

Nowadays, there is a large demand for smart textiles by consumers. Smart textiles have different functions, and can provide comfort, safety and protection. In this study, electro-conductive woven cotton fabric is prepared in two steps. The cotton fabric samples are first impregnated and padded with a polyvinyl alcohol solution of 5% for multiple cycles (1, 3, 5 and 7 cycles) and dried. Then, silver nanoparticles are deposited onto the fabric through magnetron sputtering technology. The coated samples are examined using a Fourier transform infrared spectrometer, scanning electron microscope and X-ray diffractometer. The ultraviolet blocking, infrared reflection, electromagnetic shielding, and antibacterial properties are evaluated, as well as the contact angle, light transmittance and electrical conductivity. The results show that a polyvinyl alcohol film is successfully formed and the cotton fabric fibers are stuck together through hydrogen bonds. The light transmittance is increased after the polyvinyl alcohol pretreatment. After undergoing seven cycles of coating with polyvinyl alcohol, the silver nanoparticles-coated samples show large contact angle of 127.6°, excellent ultraviolet blocking property, a high infrared reflectivity of 30%, electrical resistivity of 1.46 × 10–6 Ω·m, electromagnetic interference shielding effectiveness of −20 dB and antibacterial efficacy of >99.5%. Compared to the untreated and silver-coated cotton without impregnation of polyvinyl alcohol, the silver nanoparticles–polyvinyl alcohol-coated cotton fabric sample has excellent performance, which makes it a promising textile with a multitude of protective properties.

Abstract:

Reliability in various conditions for Li-ion batteries has been considered one of the most important factors when determining usability. Silica-based fabric has great potential to be an alternative material for electrode support, providing mechanical and physical stability in lithium-ion batteries. In this study, a carbon nanotube (CNT)-coated quartz woven fabric electrode (C-QWF) with impressive electrochemical characteristics was synthesized via a sequential two-step deposition process using Al and Fe as metal catalyst and CH4 as a carbon source. The C-QWF electrode exhibited a considerable specific discharge capacity of 369 mAh g−1 at a rate of 0.1 C-rate after cycling. The battery cell showed self-recovering ability during the cycling test at 1 C-rate, although the silica fabric has sluggish electrical conductivity. The C-QWF electrode has a superior electrochemical performance, providing new perspectives on textile fabric electrodes for robust Li-ion batteries, especially load-bearing structural batteries.

Abstract:

The paper proposes the analytic modelling of flexible textile shields made of fabrics with inserted conductive yarns and metallic plasma coating in order to calculate their electromagnetic shielding effectiveness (EMSE). This manufacturing process is highly innovative, since copper plasma coating improves EMSE on the fabrics with inserted conductive yarns of stainless steel and silver with 10–15 dB in the frequency range of 0.1–1000 MHz, as shown by the measured EMSE values determined according to the standard ASTM ES-07 via the Transverse Electromagnetic (TEM) cell. On the other hand, modelling of EMSE for such conductive flexible shields gives an insight on estimating EMSE in the design phase of manufacturing the shield, based on its geometric and electrical parameters. An analytic model was proposed based on the sum of EMSE of the fabric with inserted conductive yarns and EMSE of the copper coating. The measurement results show close values to the proposed analytic model, especially in case of fabric with conductive yarns having stainless steel content.

Abstract:

In this study, the yellowing behavior of cellulose powders, which is applied to pretreated polyester woven fabrics with concentrations of 100 g/kg by knife coating technique, was investigated. After drying process, coated fabrics were cured at different conditions to determine the effects of the curing temperature and time on yellowing behaviors. The yellowness–whiteness of coated fabrics was measured with a spectrophotometer according to ASTM E313. As the curing temperature and time increase, yellowing effect was more observable. However, the effect of temperature increase is found to be more significant than the increase in curing duration in terms of more observed yellowness. In order to investigate the reason of yellowing, cellulose powder samples were heated in drying oven at three different heating temperatures (130°C, 150°C, and 170°C) for three different heating periods (3, 5, and 7 min). Then, thermal gravimetric analysis and Fourier transform infrared spectroscopy analysis of powder samples were performed for each temperature–period combinations. No ring-opening reaction on the cellulose group was found in the Fourier transform infrared spectroscopy analysis. However, the changes in the spectra can be attributed to the chain breakage in the cellulose macromolecules as well as water loss from the molecular structure during the heating process. Microscopic and scanning electron microscopic analysis was carried out to see any surface change on the fiber and coated fabric. There was no detectable surface change on the fiber and coated fabric surface, apart from a color change on the fabric surface.

Abstract:

Textile fabrics are often subject to abrasion, starting from exposed parts of garments to a variety of technical textiles. Abrasion protection by usual coatings, however, can significantly decrease the water vapor transport through a fabric which is often not desired, especially in the case of garments. In our paper, we report on an approach to combine increased abrasion resistance with sufficient water vapor transport properties. For this, different polymers (poly(methyl methacrylate), acrylonitrile butadiene styrene, or amorphous polyamides) were coated on cotton and polyester woven fabrics. The results of abrasion tests against sandpaper show significantly increased abrasion resistance. The absolute evaporation resistance, measured by a Permetest testing device, was only slightly increased up to values still acceptable for typical garments. Images of all coatings by helium ion microscopy deliver an explanation for the measuring results. Polymer coatings on the polyester fabric resulted in a slight reduction of the hydrophobicity, while coating the cotton fabric severely increased the contact angles of the originally superhydrophilic material.

Abstract:

Electromagnetic radiation may cause interference for the proper functioning of electronic equipment and risks for human’s health. Protection against the hazards of EM radiation on various frequencies may be achieved by flexible textile fabrics with electrical conductive properties. A novel technology for imparting conductive properties to fabrics is utilizing magnetron sputtering of metallic thin films. This research focuses on plasma coated fabrics with three types of metallic layers: Nick el, Chrome and Titanium. PES woven fabrics of 88 g/m2 were coated by plasma magnetron sputtering with these three types of metals. Coating was performed on both sides of the fabric with a thickness of 400 nm. SEM images provedmetal deposition on the fiber surface, while atomic absorption tests showed the content of deposited metal. Linear resistance of coated fabrics was measured with Ohmmeter for a preliminary check of electric conductivity of the achieved fabrics. Electromagnetic shielding effectiveness tests showed a slight increase of EMSE above the noise level in the frequency range of 100-1000 MHz, of 2- 3 dB. The research studies will continue to improve shielding effectiveness of plasma coated fabrics for electromagnetic shielding

Abstract:

The stab resistance of thermoset(TS) impregnated, woven UHMWPE fabric with additional steel fabrics was investigated under dynamic stab testing conditions. Vinyl-ester resin was coated on the UHMWPE fabrics with hand lay-up process to fabricate the composite and the mental fabrics were laminated on the composites. Dynamic stab testing of targets was based on GA68-2008 for stab resistance of body armor. Six uniform specified knives impactor were used for testing. And the samples are found to present significant improvements in stab resistance (knife threat) over neat fabric targets of equal areal density. Photographs show that resin primarily reduces the mobility of yarns and enables them to stop the knife penetration more effectively in the damage zone. These results indicate that the penetration of knives through such multilayer fabrics is effectively prevented and the process could be used to fabricate flexible body armors that provide improved protection against stab threat.

Abstract:

In this article, the effect of various yarn and fabric parameters on the electromagnetic shielding of metalized fabrics coated with polyaniline has been investigated. Copper wires with diameters of 0.06, 0.08 and 0.1 mm were chosen as conductive ﬁllers for producing the metalized core-spun yarn. To investigate the effect of sheath material, cotton, viscose and polyester fibers supplied in a roving form were used to produce different core-spun yarn on a ring spinning frame. From the produced core yarn, woven fabrics were produced in three different pick densities: 12, 16 and 20 picks per cm. Polyaniline was synthesized in two chemical polymerization methods to achieve different surface conductivity. Taguchi’s experimental design was used to estimate the optimum process conditions and to examine the individual effects of each of the controllable factors on a particular response. The fabric parameters considered in this article were: copper wire thickness, sheath material type, fabric pick density and the coating compound chemical polymerization method. The electromagnetic effectiveness was measured at the frequency range of 1.7–2.7 GHz, using a waveguide. According to the level average analysis, fabric density factor shows the strongest effect on electromagnetic shielding, factor thickness of copper wire is the second and is followed by the factor coating compound chemical polymerization method and the sheath material type. The findings revealed that the samples at the frequency range 2.4–2.45 GHz show the highest shielding.

Abstract:

Abstract This study focuses on fabrication of aerogel-coated macroporous polyester fabrics for the purposes of filtration of nanometric airborne particles and potential application in facemasks. Syndiotactic polystyrene (sPS) and polyimide (PI) gels that provide respectively majority macropores (diameter > 50 nm) and mesopores (diameter 2 to 50 nm) are coated onto woven polyester fabrics via a dip coating process. The resultant materials are supercritically dried to obtain aerogelcoated fabrics. The results show that sPS is more suitable for the dip coating process. However, evaporation of the solvent during handling of gel-coated fabrics leads to closure of the surface pores that are later recovered via solvent annealing. The resultant aerogel-coated fabrics offer high air permeability (∼10–10 m2) and high filtration efficiency (> 99.95%) of airborne sodium chloride test particles of size 25 to 150 nm.

Abstract:

Integration of sensors in textile garments requires the development of flexible conductive structures. In this work, cellulose-based woven lyocell fabrics were coated with copper during an electroless step, produced at 0.0284 M copper sulfate pentahydrate, 0.079 M potassium hydrogen L-tartrate, and 0.94 M formaldehyde concentrations. High concentrations led to high homogeneous copper reaction rates and the heterogeneous copper deposition process was diffusion controlled. Thus, the rate of copper deposition did not increase on the cellulose surface. Conductivity of copper coatings was investigated by the resistance with a four probe technique during fabric deformation. In cyclic tensile tests, the resistance of coated fabric (19 × 1.5 cm2) decreased from 13.2–3.7 Ω at 2.2% elongation. In flex tests, the resistance increased from 5.2–6.6 Ω after 5000 bending cycles. After repeated wetting and drying cycles, the resistance increased by 2.6 × 105. The resistance raised from 11–23 Ω/square with increasing relative humidity from 20–80%, which is likely due to hygroscopic expansion of fibers. This work improves the understanding of conductive copper coating on textiles and shows their applicability in flexible strain sensors.

Jute and hollow conjugated polyester fibres were blended to produce non-woven composite by using a compressive hot pressing method having a weight of 328 g/m2. Its blending ratios: 50/50, 60/40 and 70/30% are considered as one factor. Needling density of non-woven fabric: 300, 150 and 75 punches/cm2 is fixed as another factor. Thermal and mechanical properties of developed non-woven composite material such as thermal conductivity and thermal resistance, breaking force and elongation were tested. Among the developed 15 samples, optimal responses are shown on 50/50% of Jute/hollow conjugated polyester fibre proportion and 150 punches/cm2 needling density. To produce three-layered winter over coat, 50% Jute/50% hollow conjugated polyester is selected as middle layer, polyurethane coated nylon and polyester fabric is used as outer and inner layer fabric, respectively. This designed over coat shows the least thermal conductivity value of 0.0195 W/m K.

Abstract:

A neodymium-doped titanium dioxide film was coated on polypropylene nonwoven fabric via a magnetron sputtering method to prepare multifunctional textiles with antibacterial and ultraviolet protective properties. The antibacterial property of the single-layer titanium dioxide film coated sample was better than that of the single-layer neodymium film coated sample. And that of the three-layer film coated samples was better than that of the double-layer film coated samples, which the latter also was superior to that of the single-layer film coated samples. A longer deposition time of the titanium dioxide film increased the antibacterial rate. The hydrophilicity of the coated samples was improved by ultraviolet irradiation, which improves the catalytic antibacterial ability. The ultraviolet protective factor of the sample that absorbs more ultraviolet is higher, and the water contact angle after ultraviolet irradiation decreases. This improves antibacterial performance. A titanium dioxide film doped with neodymium was improved without any significant change to the morphology and luster of the samples. This can lead to further applications of the coated polypropylene non-woven fabric with good antibacterial properties.

Abstract:

The increase in daily usage of electrical and electronic tools simplify the lives of human beings, on the other hand, they also create an enormous electromagnetic pollution. In industrial applications, electromagnetic shielding materials are used to prevent these electromagnetic signals. The studies on human health against the electromagnetic pollution was determined that the widely usage of these electronic devices increases the risk of cancer. Especially in low frequency fields, the most consistent evidence is obtained in childhood leukemia [1]. In order to reduce the damage of these electromagnetic waves, researches have been still made on the electromagnetic shielding effectiveness. Electrically conductive technical textiles are also investigated for this aim. Different textile structures such as knitted, woven, composite or coated textiles etc and also different conductive yarns are produced to prevent these harmful waves [2-5].In this study, it is aimed to investigate the electromagnetic shielding performances of conductive knitted fabrics. In order to search the efficiency of these fabrics, single jersey and interlock knitted structures are produced. By using these fabrics, two different types of double-layered fabric structures are formed and the shielding effectiveness of these structures are investigated experimentally [6}.

Abstract:

New photocatalytic membranes based on polylactic acid (PLA)/TiO2 hybrid nanofibers deposited on fiberglass supports were prepared and tested for the removal of ampicillin from aqueous solutions. The electrospinning technique was used to obtain hybrid nanofibers that were deposited on three types of fiberglass with different structures, resulting in three distinct photocatalytic membranes namely fiberglass fabric plain woven-type membrane, fiberglass mat-type membrane, and fiberglass fabric one-fold edge-type membrane. The results of the photocatalytic tests showed that the highest efficiency of ampicillin removal from aqueous solution is obtained with the fiberglass fabric plain woven-type membrane. Although it has been shown that the rate of photocatalytic degradation of ampicillin is high, being practically eliminated within the first 30 min of photocatalysis, the degree of mineralization of the aqueous solution is low even after two hours of photocatalysis due to the degradation of PLA from the photocatalytic membrane. The instability of PLA in the reactive environment of the photocatalytic reactor, evidenced by morphological, mineralogical and spectroscopic analyzes as well as by kinetic studies, is closely related to the structure of the fiberglass membrane used as a support for PLA/TiO2 hybrid nanofibers.

Abstract:

This paper proposes a new perspective on the analysis of fabric structures – the concept that material testing and computational mechanics are mutually dependent and, by implication, not to be considered as independent. Current representations of fabric stress-strain behaviour are based on plane-stress assumptions, and tend to simplify the available data (e.g. use of secant elastic moduli). Young's moduli and Poisson's ratios were determined for each test so as to provide the best fit plane to the scattered data points. These planar representations provided limited correlation with test data. The elastic constants do not comply with plane stress theory since coated woven fabrics are not homogeneous materials: They are composites with the interaction of orthogonal yarns making them act as a constrained mechanism. A new approach to incorporating fabric test data in structural analysis is proposed here: Use of direct correlation between pairs of stresses and strains. This avoids the inherent approximation in defining elastic constants or other parameters to quantify the fabric behaviour. A simple triangular interpolation scheme is recommended which is robust and avoids the risk of unreliable interpolation and extrapolation when using a functional representation of the data.

Abstract:

Background: Lack of interphase compatibility between the fabric and the matrix significantly impairs the load-bearing capacity of textile reinforced mortar (TRM). In this study, we consider the application of two inorganic surface coatings for enhancing the interphase bond properties. Methods: Either of two silica-based coatings, namely nano- and micro-silica, were applied to alkali-resistant glass (ARG) and to hybrid carbon–ARG woven fabric. Mechanical performance of TRM reinforced with the uncoated and the coated fabric was compared in uniaxial tensile tests. Results: Mechanical testing provides evidence of a remarkable enhancement in terms of ultimate strength and deformability for the coated specimens. This effect can be ascribed to the improved hydrophilicity of the fibers’ surface and to the activation of pozzolanic reaction at the interphase. In addition, penetration of nano- and microparticles in the bundle of the textile yarns reduces the occurrence of telescopic failure.

Fabric samples were dyed with Drimarene Reactive Red 5B and Drimarene Reactive Blue BR dyes (0.5% and 3% o.w.f) and then treated with a combination of silica nanoparticles, silane hydrophobes (alkyltrialkoxysilanes), and silane cross-linkers i.e, tetraethoxysilane (TEOS) and teramethoxysilane (TMOS) by dip-dry-cure process. After coating, wash durability of dyed samples was investigated for water repellency and water uptake according to AATCC standards. The effect of coating on dyeing behavior was assessed by measuring the (K/S)λmax value, while change in color (ΔE) and fastness properties of coated fabric also investigated. It has been observed that durable hydrophobicity achieved on cotton reactive dyed fabric through non-fluorine sol-gel route with silica nanoparticles with better fastness properties with little effect on shade.

Abstract:

In the past five decades, reinforced coated textile membranes have been used increasingly as building materials, which are environmentally exposed. Thus, their weathering degradation over the service life must be taken into account in design, fabrication, and construction. Regarding such structural membranes, PVC (polyvinylchloride)-coated PET (polyethylene terephthalate) fabric is one of the most common commercially available types. This paper focuses on the backbone of it, i.e., the woven PET fabric. Herein, weathering of uncoated PET, as the load-bearing component of the composite PET-PVC, was studied. This study assessed the uniaxial tensile strength degradation mechanisms of uncoated PET fabric during artificial accelerated weathering tests. For this purpose, exploratory data analysis was carried out to analyze the chemical and physical changes which were traced by Fourier transform infrared spectroscopy and molecular weight measurements. Finally, with the help of degradation mechanisms determined from the aforementioned evaluations, a degradation pathway network model was constructed. With that, the relationship between applied stress, mechanistic variables, structural changes, and performance level responses (tensile strength degradation) was assessed.

Abstract:

In order to prepare a time decay-resistant electromagnetic shielding (ES) fabric with good handle, moisture permeability and antibacterial properties, Cu, Ag, Ag/Cu and Ag/Cu/Ag films were deposited on PET non-woven by sputtering in screening experiment. Considering the post continues processing, this study focuses on discharge parameters optimum for a limited short time. Relationship was studied between deposited rate and ES effectiveness (ESE) for the four metallic films on various substrates. The metal deposit greatly relays on the chemical nature of the substrate and target metal category. The deposited metal rate on metal is larger than that on PET. In comparison with single metallic film, the dB value of multi-metallic film obtained for same time even for more time remarkably dropped. Therefore, an Ag-coated PET no-woven was finally fabricated as the multi-functional fabric with anti-decay ESE. The multi-functional PET no-woven with good handle obtained for 3min. by optimizing other parameters exhibits higher ESE, good anti-bacterial and moisture permeability.

Abstract:

Textiles, as a desired platform for wearable smart technology, can be integrated with smart elements in the hierarchical levels of the fabric structure. In this study, a new way to make strain sensing fabric was developed by embedding a single strain sensing carbon nanotube (CNT)-based yarn into the woven structure. To overcome the abrasion during insertion, the yarn was coated with poly(vinyl alcohol) (PVA) to achieve higher mechanical performance. The gauge factor of the yarn was improved from 0.91 to 1.64. The sensing properties of CNT/PVA yarn integrated strain sensing fabric showed a gauge factor of over 1.1, a degree of linearity of more than 97% and good stability and repeatability during cyclic loading. Fabric with different integrated yarn lengths, patterns and output connections has also been investigated. The results showed that the yarn length and bend over section had a great influence on the strain sensing properties of the fabric. Furthermore, the fabric strain sensor exhibited a quick and precise response to the finger motion detection, demonstrating potential in wearable electronics.

These paper aims to present an experimental study for determining the mechanical properties of woven fabrics used for airbags manufacturing. In order to realise the study, there were chosen two types of fabric, one that is coated with silicon and one that is uncoated. The experimental tests that were carried out were uniaxial tension tests for samples extracted on the warp and on the weft direction, the Bias test, a test specific for shear loads and the dome test, a test specific for biaxial loads. For the uniaxial tension test the force-displacement curve was obtained and the maximum values of the loads and the displacement. For the last two tests (bias test and dome test) there have been determined the maximum load, the displacement at maximum load, but also the local major strains obtained. All tests were carried out on a tensile and compression testing machine Instron 5587, while for measuring the main strains there has been used also the optical measuring system Aramis.

Abstract:

Chitosan derivatives are difficult to electrospun because they have poor flexibility of their polyelectrolyte chains. Based on extensive trails, we have successfully electrospun chitosan polymer and, subsequently, coated on non-woven polypropylene utilizing Nanospider technology. This experimentally developed nanofibrous webs of various densities were coated on non-woven fabric and, subsequently, stitched with activated carbon sphere (ACS) adhered composite fabric. Biological filtration and chemical protection were evaluated and the optimized density offering the highest value with meeting specified comfort was assessed. Results showed that optimized web morphology of 0.43 g m−2 is the best for integration with nuclear, biological and chemical absorbent layer of low ACS add-on in all aspects of comfort and protective behaviours. This will be meeting stringent defence protective requirements and lowering down the weight of suit by approximately 25%. An attempt has also been made in this research to protect from sulphur mustard chemical warfare agent by using both theories: (a) barrier techniques and (b) disintegrating the trapped molecules via functionalization of the web. Result shows that first molecules get trapped by in web layer (barrier effect) and subsequently destroyed by hydrolysis mechanism. Scanning microscopic image shows web is acting as barrier layer by trapping sulphur mustard particles. Optimized web of 0.43 g m−2 was functionalized with zinc (Zn) oxide and the presence of Zn particles was confirmed by imaging techniques. Crystalline and thermal analysis depicts that structural changes were found in sulphur mustard spotted functionalized web. Raman spectra show chemically disintegrated hydrolysed products of sulphur mustard. Bacterial filtration efficiency, antimicrobial and comfort properties were measured for assessing the introduction of nanowebs for biological protection and chemical protection in newly created multilayered fabric structure with low ACS add-on (180 g m−2). The initial encouraging outcome of this research expects whether the multilayered fabric could be introduced in the suit.

Abstract:

Two conductive formulations containing different types of micron-sized metal flakes (silver-coated copper (Cu) and pure silver (Ag)) were characterised and used to form highly electrically conductive coatings (conductors) on plain and base-coated woven fabrics, the latter in an encapsulated construction. With e-textiles as the intended application, the fabric stiffness, in terms of flexural stiffness and sheet resistance (Rsh), after durability testing (laundering and abrasion) was investigated and related to user friendliness and long-term performance. Bare and encapsulated conductors with increasing amounts of deposited solids were fabricated by adjusting the knife coating parameters, such as the coating gap height (5, 20, 50, and 200 μm), which reduced the Rsh, as determined by four-point probe (4PP) measurements; however, this improvement was at the expense of increased flexural stiffness of the coated fabrics. The addition of a melamine derivative (MF) as a cross-linker to the Cu formulation and the encapsulation of both conductor types gave the best trade-off between durability and Rsh, as confirmed by 4PP measurements. However, the infrared camera images revealed the formation of hotspots within the bare conductor matrix, although low resistances (determined by 4PP) and no microstructural defects (determined by SEM) were detected. These results stress the importance of thorough investigation to assure the design of reliable conductors applied on textiles requiring this type of maintenance.

Abstract In this study, woven fabrics with numerous electrostatic charges and desirable charge stability were investigated. A kind of core–shell monofilaments with different melting points between outer and inner layers were applied to wove the fabrics. These fabrics were hot coated through tourmaline particles as an charge enhancer at 122°C. Benefiting from the anions released by tourmaline particles and optimized content of the particles, the fabrics were endowed with surface potentials from −10 to −160 V and the voids content decreased from 45.4% to 41.2%, which contribute to the improvement in the filtration performance of the fabrics. A filtration mechanism was proposed while incremental surface charges with increasing tourmaline particles content have been confirmed through the noncontact measurement of electrostatic charges. The resultant fabrics exhibited a high filtration efficiency of 64.8% and superior long-term service performance. This study can provide a new application of the screen window for PM 2.5 governance.

In this study, a type of double-layer electromagnetic shielding fabric that combined reflection and absorption layers was successfully fabricated. Polypyrrole-coated cotton fabric was prepared by in situ polymerization and used as electromagnetic wave absorbed layer. A type of metal composite yarn containing stainless steel wire was woven into warp-knitted fabric as the reflection layer of double-layer electromagnetic shielding fabric. The electromagnetic shielding and conductive properties of double-layer electromagnetic shielding fabric were investigated in this work. Result showed that the electromagnetic shielding effectiveness could reach up to 15 dB in a large frequency range from 500 MHz to 1.5 GHz. The electrical conductivity of polypyrrole-deposited cotton fabric was 0.15 S/cm. To investigate the physiological wear comfort of prepared sample, the effect of moisture content on drying rate and air permeability was also discussed. Results indicated that the existence of polypyrrole on the cotton fabric displayed negative influence to water absorption. Furthermore, it was also found that the air permeability of electromagnetic shielding fabric decreased linearly with the increased water content in the fabric, and the air almost could not pass over the fabric when the water content reached approximately 80%. The study was designed in order to have a clear understanding of double-layer electromagnetic shielding fabric and provide advice to produce protective clothing to protect humans from electromagnetic radiation.
