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:
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:
The incorporation of inflatable structures into aerospace systems can produce significant advantages in stowed volume to mechanical effectiveness and overall weight. Many applications of these ultra-lightweight systems are designed to precisely control internal or external surfaces, or both, to achieve desired performance. The modeling of these structures becomes complex due to the material nonlinearities inherent to the majority of construction materials used in inflatable structures. Furthermore, accurately modeling the response and behavior of the interfacing boundaries that are common to many inflatable systems will lead to better understanding of the entire class of structures. The research presented involved using nonlinear finite element simulations correlated with photogrammetry testing to develop a procedure for defining material properties for commercially available polyurethane-coated woven nylon fabric, which is representative of coated materials that have been proven materials for use in many inflatable systems. Further, the new material model was used to design and develop an inflatable pathfinder system which employs only internal pressure to control an assembly of internal membranes. This canonical inflatable system will be used for exploration and development of general understanding of efficient design methodology and analysis of future systems. Canonical structures are incorporated into the design of the phased pathfinder system to allow for more universal insight. Nonlinear finite element simulations were performed to evaluate the effect of various boundary conditions, loading configurations, and material orientations on the geometric precision of geometries representing typical internal/external surfaces commonly incorporated into inflatable pathfinder system. The response of the inflatable system to possible damage was also studied using nonlinear finite element simulations. Development of a correlated material model for analysis of the inflatable pathfinder system has improved the efficiency of design and analysis techniques of future inflatable structures.

In this study, polyvinyl alcohol-coated PET non-woven fabrics were prepared by crosslinking PVA with Borax onto the surface of PET non-woven fabrics, yielding a three-dimensional network structure. The PVA-coated PET non-woven fabrics were then activated by epoxidation, coupled with IDA (chelating agent), and loaded with Cu2+ to attain an immobilized metal affinity (IMA) absorbents. The effect of PVA concentration, activating agent concentration and activation time on the amount of chelated metal ion were analyzed by RSM (Response Surface Methodology) to decide the optimum values of independent factors for the best response value. The results showed that the PET non-woven fabrics modified with molecular weight 90,000 of polyvinyl alcohol had mass ratio 90%, while the swelling ratio increased from 52% to 75%. The PVA-coated PET non-woven fabrics were easily distinguished from uncoated and coated preparation through SEM. It was found that when PVA concentration 6%, activating agent concentration 30% and, activation time 20hr, the amount of immobilized Cu2+ reached 78 mmol/m2. The results from RSM reveal the reliability for this study. Afterward, we show that the immobilized metal affinity (IMA) absorbents have the ability of. However, it was found that with increasing the concentration of PVA caused a block behavior on absorbents. Hence, it is necessary to keep a suitable porous size, or it will easy to lose the utility of protein adsorption from the prepared absorbents.

Abstract:
Ceramic coated fabrics have been employed for heat resistant clothing such as fire-fighters gears, fire-proof insulators, and heating and cooling insulators. Thus, transient heat conduction and thermal properties of such fabrics are needed for the design of the clothing. The goal of this study is to measure the transient heat conduction and the coefficient of thermal expansion of ceramic coated fabrics with different woven morphologies. This has been accomplished through an experimental setup consists of a hotplate assembly, applying a uniform temperature, with the accuracy of +/− 1 °C in less than 500 msec, a ceramic coated fabric and an infra-red thermometer assembly. This set up has been validated by using a known material such as aluminum and copper for the coefficient of thermal expansion measurement. The hot plate temperature was varied between 30 to 400°C within 300 seconds. The transient heat conduction and the thermal coefficient of the woven ceramic coated fabrics were compared with ceramic nonwoven fabrics materials. Finally, upon comparing different samples and measuring the coefficients of thermal expansion, K’s, the level of delay in heat transfer with respect to time has been determined.

Full text
Abstract:
Coated woven fabrics are often used as stressed membranes in inflatable and tension structures. When the stressed fabrics in such structures are damaged locally, the damage site often provides a starting point for the propagation of a tear. In this paper, a micromechanical model is developed for predicting the onset of tearing at slit-like damage sites in biaxially stressed coated woven fabrics. The stress concentration in the first intact yarn adjacent to the slit is determined as a function of increasing remote stress, and predictions for tearing onset are made assuming that tearing initiates through the rupture of the first intact yarn when the maximum tension in the yarn reaches the yarn ultimate breaking load. A crucial aspect of the model is the treatment of inelastic deformation involving yielding and/or separation of the coating and relative slip between interlaced yarns near the slit tip. Inelastic deformation near the slit tip leads to significant reduction in the stress concentration compared with the elastic deformation case and, therefore, acts to inhibit the onset of tearing. A single dimensionless parameter is shown to govern the stress concentration at tearing versus slit length behavior of particular fabrics. The parameter may be interpreted as a measure of the slit damage tolerance of coated fabrics and shows how particular microstructural properties of the fabric (coating yield stress, coating shear stiffness, yarn axial stiffness, etc.) affect tearing onset. A series of experiments on various coated nylon and polyester fabrics are conducted using slit-damaged cruciform specimens in a simple biaxial test frame. Initial slit lengths in these tests ranged from five to 61 consecutive yarn breaks. The model is shown to capture the onset of tearing in these fabrics over a range of slit lengths quite well.

Abstract:
Life Cycle Assessment (LCA) studies represent the scientific approach for elaborating modern policies and supporting management decisions in the field of Sustainable Production and Consumption. The goal of many LCA studies undertaken for research are related to an exhaustive comparison of a modern, innovative product or process with respect to an initial, conventional one. This paper deals with such an approach for fabric based electromagnetic shielding. Electrically conductive textile fabrics are used in applications of electromagnetic shielding. Two basic types of technology for imparting electro- conductive properties to textiles are available, namely: insertion of conductive yarns in the fabric structure and coating with conductive layers. Magnetron plasma coating is a modern technology for achieving thin metallic layers on fabrics. Therefore, we focused the LCA study to the comparison between cotton woven fabrics with inserted conductive yarns out of stainless steel in warp and weft direction and cotton fabrics coated with thin layers of copper by magnetron plasma laboratory equipment. Functional unit of the comparative study was one square meter of EM textile shield with 5.2 dB at 1 GHz. A modelling of the fabric with inserted conductive yarns was performed in order to reach same shielding effectiveness at a certain frequency, as in the case of the coated fabric. Inventory data was collected for the fabric with conductive yarns from the textile company SC Majutex SRL, while for the plasma coated fabric from INFLPR. Impact assessment was performed by INCDTP, by using the LCA software SimaPro7 and the data basis EcoInvent 3.0. Interpretation of results shows that weaving of conductive yarns has a smaller impact on the environment than magnetron plasma coating using laboratory equipment, in a ratio of 1:2. This fact is explained by the industrial process of weaving as compared to laboratory process of coating, whereas brings the idea that upon utilization of industrial magnetron equipment for coating one may achieve in the end better environmental impact due to the process optimization for large area plasma processing.

Abstract:
Electromagnetic (EM) waves, such as electronic noise and radio frequency interference can be regarded as an invisible electronic pollution which justifies a very active quest for effective electromagnetic interference (EMI) shielding materials. Highly conductive materials of adequate thickness are the primary solutions to shield against EMI. Equipment cases and basic structure of space aircraft and launch vehicles have traditionally been made of aluminum, steel and other electrically conductive metals. However, in recent years composite materials have been used for electronic equipment manufacturing because of their lightweight, high strength, and ease of fabrication. Despite these benefits, composite materials are not as electrically conductive as traditional metals, especially in terms of electrical grounding purposes and shielding. Therefore, extra effort must be taken to resolve these shortcomings. The present work demonstrates a study on developing hybrid composites based on fiberglass with surface grown carbon nanotubes (CNTs) for EMI applications. The choice of fiberglass is primarily because it naturally possesses poor electrical conductivity, hence growing CNTs over glass fiber surface can significantly improve the conductivity. The fabrics were sputter-coated with a thin layer of SiO2 thermal barrier prior to growing of CNTs. The CNTs were grown on the surface of woven fiberglass fabrics utilizing a relatively low temperature technique. Raw fiberglass fabric, SiO2 coated fabric, and SiO2 coated fabric which was subjected to the identical heat treatment as the samples with CNTs were also prepared. Two-layers composite specimens based on different surface treated fiberglass fabrics were fabricated and their EMI shielding effectiveness (SE) was measured. The EMI SE of the hybrid CNT-fiberglass composites was shown to be 5–10 times of the reference samples. However, the tensile mechanical properties of the composites based on the different above mentioned fibers revealed significant degradation due to the elevated CNT growth temperature and the addition of coating layer and CNTs. To further probe the structure of the hybrid composites and the inter-connectivity of the CNTs from one interface to another, sets of 20-layers composites based on different surface treated fabrics were also fabricated and characterized.

Abstract:
Edge Finishing processes used in this study included Abrasive Water Jet and Carbide Router Endmilling for the trimming of the laminate material. For drilling of holes in the laminate material, Polycrystalline Diamond drills and Chemical Vapour Deposition (CVD) diamond coated carbide drills were used. Test material was machined with these processes and resultant surface integrity was recorded using a Surface Profilometer, Edge Replication using acetate tape and Scanning Electron Microscopy (SEM). The machining processes result in macroscopic defects which lead to the damage evolving with service loadings which can result in failure of the CFRP laminates in service. This study was conducted to research the effects of machining processes on residual strength of laminates. A 20 ply thick balanced symmetric [90/-45/0/-45/90/45/0/-45/0/90/0]s laminate was used in this study with a nominal thickness of 4.19 mm and with an average ply thickness of 190 μm. The laminate had a top layer of woven fabric material [0/90] and a bottom layer of fiberglass skin material. Mechanical testing was conducted on test specimens to failure for the tensile strength, compressive strength, open-hole tensile strength, open hole compressive strength and bearing strength. The failure mode and damage of the test specimens for each case was examined and discussed.
