The fabrics intended for clothing have more emphasis on their appearance and handling characteristics such as luster, smoothness or roughness, stiffness or limpness, and draping qualities. Nowadays, evaluating fabric touch can be of great interest in the industry to match the quality needs of the consumer and the parameters for the manufacturing process. Throughout this study, the effect of weave types on the surface roughness of cotton woven fabric was investigated and analyzed. Three different weave types namely, plain 1/1, twill 1/3, and sateen 8/3 were investigated. The fabric parameters were 27*20Ne (warp/weft) count of yarn, 38*18 (EPC [Ends per Centimeters]/PPC [Picks per Centimeters]) thread density, and 710 CN/TEX (Cent-newton per Tex) with warp tension was produced by air-jet loom. The findings of this study revealed that the surface roughness values of all the fabrics increased regularly on moving from plain 1/1 weave to sateen 8/3 weave. But, the surface roughness of fabric in the weft direction is higher than in the warp direction. The weave type is statistically significant at a confidence interval of 95% and can effectively be used to describe the surface roughness for both warp and weft direction of woven fabrics. The pairwise comparison reveals that it is statistically significant for weave types in the warp and weft direction of the fabrics. This investigation and analysis of weave types on surface roughness of cotton woven fabrics help textile technologies and manufacturers to consider the weave types during the production of fabrics for different end applications.

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.

Air and moisture transport properties of plain woven fabric made from 20sNec cotton in warp and 20sNec pure yarns of tencel, modal, pro-modal, bamboo, polyester and cotton yarn inweft direction are studied. Major characteristics added for this study include water vapour permeability, air permeability, wettingtime and wicking speed. In comparison of six different samples of variously composed materials in weft direction, the air permeability of tencel was minimum and polyester was maximum, whereas the reverse results were observed for both the samples in case of water vapour permeability. Among the blends with cotton, thermal conductivity of bamboo and thermal absorptivity of polyester was found maximum whereas the minimum thermal resistance was observed for pro modal yarn in weft. Similar pattern was observed in spreading speed and wetting time of the polyester when observed from either side top or bottom. Air and moisture comfort properties of bamboo and pro modal, having nearly similar values are suggested to be used in garments used for golf players

AbstractElectro-conductive (EC) yarns can be woven into a hybrid fabric to enable electrical current to flow through the fabric from one component A to another component B. These hybrid fabrics form the bases of woven e-textiles. However, at the crossing point of an EC yarn in warp and in weft direction, there is a contact resistance and thus generation of heat may occur in this area. Both phenomena are inseparable: if the contact resistance in the EC contact increases, the generated heat will increase as well. Predicting this electrical and thermal behavior of EC contacts in hybrid woven fabrics with stainless steel yarns is possible with a mathematical model based on the behavior of a metal oxide varistor (MOV). This paper will discuss in detail how this can be achieved.

This experimental work investigates the effect of yarn structure on cover factor of fabrics at different weft settings by the light transmission method. To analyze the effect, two different types of fabric set have been prepared by using airjet and rotor yarns of the same linear densities in the weft direction and keeping the warp yarn unchanged. For each fabric, weft setting has been changed gradually. Cross-sectional diameter of yarn and its packing density has been analyzed to find out the differences between both yarn structures. The effective yarn diameter and packing density have been found to be almost same for both yarns while the hairiness is found to be higher in airjet yarn as compared to rotor yarn. Yarn cross-section in the fabric has also been analyzed to examine the deformation (flatness) in yarn, which was relatively higher in airjet yarns. At the same weft setting the cover factor (CF) of fabric woven by air jet yarn is found to be higher than fabric woven by rotor jet yarn, and this difference decreases as the weft setting increases in fabric. Correlation analysis results show the relation between the cover factor and weft setting. While analysis of variance results show statistically significant effect of spinning system (airjet and rotor yarn) and weft setting on the cover factor of woven fabric.

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.

Anisotropy is the characteristic which is typical for most materials, especially woven fabrics. Influence of direction of tensile force action on the properties of the fabric is big and frequently tested. The woven fabric can be defined as orthogonal elastomer. The values of elastic modulus of woven fabrics for different angles of extension direction were analyzed. Three types of fabric samples of different weaves (plain, twill, sateen) and the same raw material composition were tested under tensile forces in seven directions oriented with 15° increment with respect to the weft direction. Elastic modulus of woven fabrics was determined experimentally in the laboratory. Based on the experimentally obtained values, theoretically calculated elastic modulus for arbitrarily chosen fabric directions was calculated. A good agreement between experimental results and the calculated obtained values of the elastic modulus was shown, so the theoretical equations can be used with high accuracy to calculate the elastic modulus of the fabric in various directions. Therefore, the measurements need to be implemented when the tensile force acting on the fabric only in the warp (90°), weft (0°) and at angle of 45°.

AbstractFabric surface tribology is an important area of study in upholstery fabrics, which is exposed to high friction and abrasion effects. In the studies on the tribology of upholstery fabrics, it is ensured that criteria such as better performance, less degradation, increased usage time, and user comfort are determined and taken into consideration in the woven fabric design. Surface roughness and friction coefficients are important parameters used in determining abrasion, deformation, and wear behaviors of fabrics. In this study, the surface abrasion behaviors of upholstery fabrics woven with basic and jacquard weave patterns and also different structural parameters were investigated in terms of the changes in surface roughness parameters (amplitude parameters: Ra, Rpm, and Rvm and hybrid parameters: Δa) and the changes in surface friction coefficients. These results were also related to the state of the visual changes in the fabrics. Rpm, Rvm, and Δa being roughness parameters were found to be important in the evaluation of the surface deformation of the fabrics after abrasion besides the Ra parameter. Results showed that the Δa roughness parameter could be suitable for evaluating the deformation of the textile structures to be used, particularly in sensitive applications.

In order to release the influence of shedding motion on warp tension fluctuation, easing device is often set on short looms with single back rest system. With the decrease of the beam’s diameter, the wrapping angle formed by warp and the active back rest will become bigger, and the effect of the easing device will be more significant. However, the wrapping angle of the double back rest system is a constant while the change of the beam’s diameter. The effect of easing device on air-jet looms of double back rests system is analyzed in this paper, and conclusion has been made that the easing device can be eliminated on the double back rests system.
