Overall Bending

In this research, the bending property of jacquard woven fabrics and the effects of weft density, weft yarn count, weave, and Lycra inclusion in weft yarn on this property were investigated. Viscose filament warp yarn and polyester and polyester/Lycra weft yarns were used for weaving fabrics, and 4/1 and 7/1 satin weaves with the same jacquard design were used as the ground weave. Experimental results show that the bending rigidities of the fabrics in the warp directions increase as the weft density increases and the weft yarn gets thicker. The bending rigidities of the fabrics woven with a 4/1 satin weave in the warp direction are higher compared to the bending rigidities of the fabrics woven with a 7/1 satin weave in the same direction. Similar to the bending rigidities in the warp direction, as the weft density increases and the weft yarn gets thicker, the bending rigidities of the fabrics in the weft directions increase. When the weft yarn includes Lycra, the bending rigidity values of the fabric decrease in the weft direction. Additionally, similar to the bending rigidity in the warp direction, the jacquard woven fabrics with a 4/1 satin weave have a higher bending rigidity in the weft direction compared to the jacquard woven fabrics with a 7/1 satin weave. It was observed that when the weft density increases, the overall bending rigidities of the fabrics increase. Despite fabrics woven with a polyester/Lycra weft yarn having a thicker weft yarn and heavier weight with the same weft density and weave compared to fabrics woven with a polyester weft yarn, the bending rigidity values in the weft direction have a lower overall fabric bending rigidity.

Auxetic textiles are defined as textiles with negative Poisson’s ratio. These textiles possess unique properties that render them suitable for special applications. This work aims to investigate the effect of fabric structural parameters such as thread densities, weave design and warp yarn count. Thus, 30 fabric samples were woven at 3 weft and 2 warp densities, respectively. Two warp counts and three weave designs of plain, basket 3/3 and weft-backed satin 6 were used. The samples were uniaxially loaded in weft direction and dimensional changes at various strains levels were evaluated. The evaluation was carried out using the image processing technique based on MATLAB software. The weft yarns used were found to exhibit auxetic behavior at the whole spectrum of the strain level used. The least weft yarn Poisson’s ratio was found to be −0.9. It was established that in general the fabric samples exhibit auxetic effect within the stated range of strain. Additionally, it was concluded that while fabric thread densities together with warp count influence the minimum fabric Poisson's ratio, auxetic behavior of the samples is not dependent on weave design alone. Rather, it was illustrated that the combined effect of weave design in association with stated structural parameters on auxetic feature cannot be ignored.

Cutting Processes

Cutting processes using blades have found applications in many industries; for example, in garments, fiber–polymer composites, and high-performance fabric forming. In recent decades, the process of cutting the material using a robotic-controlled blade has raised concern about the value of the pressure and the cut force required for a certain type of woven fabric and the estimation of its value before the pressing and cutting process. A simple theoretical relation was established based on the fabric structure and yarn shear stress. The model formulation and experimental results to describe the basic theory of blade cutting fracture for woven fabric of different designs was derived. In this work, the experimental investigation of the effect of the fabric specifications, normal load, and the cutting speed on the cutting force was carried out, which indicates that the value of the specific cutting resistance of the fabric was found to be highly correlated with the fabric structure, warp and weft yarn count, Young’s modulus of the fabric, and fractional cover factors ratio ζ.

Fabric Strength

Tensile strength has been accepted as one of the most important performance attributes of woven textiles. In this work, multiple linear regression models are developed by using empirical data for the prediction of woven fabric tensile strength manufactured from cotton yarns. Tensile strength of warp & weft yarns, warp & weft fabric density, and weave design were used as input parameters to determine warp- and weft-way tensile strength of the woven fabrics. The developed models are able to predict the fabric strength with very good accuracy. Warp yarn strength and ends per 25 mm are found to be the most dominant factors influencing fabric strength in warp direction while weft yarn strength and picks per 25 mm are most vital in weft direction.

The Difference

Purpose – The traditional Japanese cotton-crepe fabric chijimi has been used for summer clothing for over a century because of its good skin comfort. The high extensibility of this fabric relies on the high-twist cotton yarns used in the weft direction. The purpose of this paper is to show the effect of environmental humidity on the extensibility of highly twisted cotton yarns to help in choosing weft yarn suitable for woven fabric. Design/methodology/approach – Four highly twisted cotton yarns are examined under 10-90 percent RH and in 25°C water. Cyclic tensile tests are performed to obtain the tensile energy, resilience, extensibility at maximum applied load (EM), and residual strain. Findings – Comparing the same yarn-count samples Y1 and Y2, the EM of Y2 (2,200 T/m) is larger than that of Y1 (1,000 T/m) under all RH conditions, and the difference increases at humidity over 60 percent RH. For fabric crepe samples woven by Y1 (warp) and Y2 (weft), the extensibility (EM-1) in the weft direction is in the range 16-26 percent, which is equivalent to that of outer-knitted fabrics. The extensibility and recovery of chijimi is largely dominated by the twist of weft yarns, which is also influenced by changes in relative humidity. Originality/value – The skin comfort of Takashima chijimi has been of interest, but the high extensibility of this cotton fabric has not been given much attention. The results of this study show that yarn twist is key to controlling extensibility in high-humidity environments.

The effect of weft yarn filament fineness on the surface roughness of fabrics woven from polyester yarns through different fabric constructional properties was investigated. Warp yarn type and count and warp density were the same but weft yarn count, weft yarn filament fineness/numbers, and weft density were different for the fabrics in the experimental sub-groups. An objective assessment for surface roughness measurement of woven fabrics by using a stylus profilometer was made. Experimental results show that yarn filament fineness affected fabric porosity and fabric surface roughness. Fabrics with finer filaments could have a compact structure due to small porosity values between the filaments inside the yarns and between yarns themselves in fabrics. Closeness of yarns in fabric structure decreased differences between high and low peaks on fabric surface, and as a result fabric surface roughness decreased.

Mesoscale modelling approach has shown close simulation approximations of woven fabric tensile performance. The main purpose of the work is to develop understanding of geometrical model development, finite element analysis procedure and to compare the differences of 2D and 3D woven fabric uniaxial tensile stress-strain. 3D woven fabric structures selected for the work is three-layer orthogonal woven fabrics. The woven structure will have 2 through-thickness warps, 4 non-crimps warp and 6 wefts. Through-thickness warp yarn will apply plain 1/1 weave structure for stitching all weft layers and non-crimps weft yarn together. Woven geometric models were developed with pre-processor program at detail yarn configurations. Simulation results showed that 3D orthogonal woven fabric had a better tensile response than its 2D woven fabric structures.

The paper investigates the influence of fabric structure variations and finishing on the thermal properties of woven fabrics for a tailored garment. Four distinctive pairs of fabrics were investigated, where the weft density, weft yarn count or type and finishing were varied within the fabrics in each pair. Several thermal properties such as conductivity, diffusivity, absorptivity, resistance, the ratio of maximal and stationary heat flow density and the stationary heat flow density were measured using an Alambeta device. The results obtained showed that variation of the weft yarn count and finishing have a significant effect on several thermal properties. Increasing the weft count increased the thermal conductivity, absorptivity, resistance and the ratio of maximal and stationary heat flow density. The application of oilproof and waterproof finishing affected thermal diffusivity, thermal absorptivity and thermal resistance. Milled finishing contributed to increasing the thermal resistance.

Recently, development of technology increases human life quality and gradually raises the value of health protection in human’s concept. Bamboo has multi-functional including far infrared radiation, deodorization and anion generation. Therefore, bamboo charcoal has been widely used in textile industry. Moreover, development of technology also increased the electromagnetic hazard in human’s daily life. This study aims to develop a manufacturing process of functional composite yarn-dyed woven fabrics. In the manufacturing process, the materials included pure cotton yarn, stainless steel fiber(called metallic yarn) and viscose rayon yarn containing bamboo charcoal (called bamboo charcoal yarn) were used for making the bamboo charcoal/stainless steel composite woven fabric. The composite woven fabrics were woven by using same warp yarn and two kinds of weft yarn that contained bamboo charcoal and stainless steel. The composite fabrics had two different structures. Those fabrics were changed the order of bamboo charcoal yarn and metallic yarn. The ratios of weft yarn were 1 end of bamboo charcoal yarn to 1 end of metallic yarn and 3 ends of bamboo charcoal yarn to 1 end of metallic yarn. Furthermore, the fabrication of composite fabrics that included plain, 2/2 twill and dobby were changed. The composite woven fabrics were finished and laminated by TPU film to enhance the waterproof and vapor permeable functions. The laminated composite fabrics were evaluated by far-infrared coefficient, anion generation rate, water vapor permeability, water resistance, surface electric resistance and electromagnetic shelter property to obtained optimal manufacturing process.

AbstractThe surface characteristics of fabrics are important from the point of view of the sensorial comfort of clothing users. Surface friction and surface roughness are the most important surface parameters of fabrics. These parameters can be measured using different methods, the most important and well-accepted method being that using the Kawabata evaluation system (KES)-FB4 testing instrument. In this work, the surface roughness and surface friction of the seersucker woven fabric have been determined using the KES-FB4. However, the measurement procedure needs modification. On the basis of the results, the influence of the repeat of the seersucker effect and the linear density of the weft yarn on the surface parameters has been determined.

Tearing Strength

The synthetic leather base is a composite, with the top and lower layers are nonwovens and the middle is woven fabrics. Firstly, the single rip tearing strength and drawing out resistances of the leather base were tested and tearing failure mechanics were analyzed. Then on the above basis, the single rip tearing strength calculation model of the synthetic leather base was built successfully. From theoretical model, main influencing factors are the weft and warp yarn breaking strength and the density of warp and weft yarns in the woven fabric, and also drawing out resistance of the leather base. Finally, experimental verification was made for the established model, which shows that theoretical values conform to the measured values well.
