In order to understand the influence of the blended ratio of the soybean protein fibers to the properties of blended fabrics, five soybean protein fiber/modal blended fabrics are knitted and tested. By the analysis of the results, the relationship between the properties of the blended fabrics and the blended ratio of the soybean protein fibers are obtained. With the increase of the ratio of the soybean protein fibers, the tensile strength and the elongation of the blended fabrics increase and the tearing strength and bursting strength of the fabric decrease. With the increase of the ratio of soybean protein fibers, the softness increases and the bending length, abrasion resistance of the knitted fabrics decrease.

The present paper attempts to investigate the relationship between fabric porosity and light permeability of the knitted structures, namely, rib 1 × 1, rib 2 × 1, single jersey, and plain structure. The rationale is that pores (in a fabric) would allow light to pass through but at the same time provide a quantitative assessment of the UV light permeability of the knitted fabrics, an indication of the protective capacity of the fabrics against UV radiation. The porosity and corresponding light permeability of the knitted structures were measured after varying the following knitting parameters: stitch length, stitch density, and tension on the machine. Furthermore, this work has enabled the development of an apparatus that can measure the amount of light transmitted through the knitted fabrics. The results generated by the equipment were validated through the use of regression equations.

One of the most important stages in the design process of compression products is describing the relationship between the force and elongation of the knitted fabric, using appropriate and scientifically justified force values in the fabric undergoing a stretching and relaxation test, in the form of a hysteresis loop. Research on this issue was carried out on two variants of knitted fabrics with elastomeric threads – a warp and a weft – knitted one. Based on the functions of the relation between the force and relative elongation determined and on Laplace’s law, compression bands with intended values of unit pressure were designed and manufactured and then subjected to experimental verification. In addition, a procedure was presented for dividing compression fabrics into specific compression classes.

Abstract This study investigated the elastic elongation and elastic recovery of the elastic warp knittedfabric made of PET( polyethylene terephthalate) and PBT(polybutylene terephthalate) filament. Using 50/24F PET and 50D/24F PBT in two threadingbars, the tricot, locknit and satin warp knitted fabrics were produced on the E28 tricot warpknitting machine. The knitting parameters influencing the elastic elongation under 100N wereanalyzed in terms of fabric structure, yarn run-in speed and drawing density set on machine.Besides, dyeing temperature and heat setting temperature/time were also examined in order toretain proper elastic elongation and elastic recovery. The relationship between elastic elongationand knitting parameter and finishing parameter were analyzed. Finally, the elastic recovery ofPET/PBT warp knitted fabric was examined to demonstrate the elastic property of final finishedfabric. This study could help us to further exploit the use of PET/PBT warp knitted fabric in thedevelopment of elastic garment in future.

Simple Technology

Comfort is not a feature of textile material, but a pleasant feeling in humans affected by many factors, including the characteristics of textile material. Comfort is an important factor for consumers that influences the decision when buying clothes and determines customer satisfaction with products. Thermophysiological comfort refers to the feelings of hot, cold, dry, wet and is influenced by environmental factors such as heat, moisture and movement on the air. In recent years, interest in knitted products has been growing owing to the simple technology for their production, low costs and a high level of comfort of knitted garments. Knitting technology faces rapid changes in terms of the requirements of fashion and customer performance. Knitted fabrics should not only have stretch and provide freedom of movement, but they should also be soft and easily transmit vapor from the body. The demands of consumers regarding the quality of clothing are changing in accordance with the development of textile technology and the rise in the standard of living. Assuring the thermal stability of the human body is one of the most important functions of clothing. Knitted fabrics are hygroscopic and have good thermal conductivity. They have the ability to submit multiple uses without significant changes in external appearance. Clothing that manages the moisture, thus enabling the body to feel dry and comfortable, is one of the main criteria for quality clothing. The ease with which the knitted fabric transports moisture from the body depends on the characteristics of the fiber, that is, the raw material composition, but even more so from the geometric characteristics of the knitted fabric. The paper examined the permeability of water vapor in cotton knitted fabric for underwear made from cotton yarn of the same fineness, embedded in three different interlacing, single jersey, double jersey 1: 1 (rib) and interlock jersey. According to the results, the two-sided interlacing double jersey 1: 1 (rib) and interlock jersey have shown better water vapor transport, which means that t-shirts made from these knitted fabrics will absorb the sweat faster from the body, giving them a feeling of greater comfort. The choice of appropriate clothing for a particular purpose should be made on the basis of user requirements, the thermal characteristics of the material and the interaction between the material and the user in different environments.

The morphology and dimension of wool fibers were compared from the usually processed in the wool applications to investigate the relationships between shape and dimensions of wool and fuzzing and pilling of knitted fabrics. The frictional coefficients of wool fibers were measured by capstan method. The surface morphology were observed by scanning electron microscopy (SEM), and the cuticle scale edge height (CSH) were measured to verify the relationship between CSH and the differential friction effect (DFE). The hairiness and tensile properties of yarn were also reported. The pilling comparative experiments of the corresponding knitted fabrics were conducted with the ICI pilling box according to GBT 4802.3-2008. The pilling grades were estimated by numbers of pills. Experimental results showed that the CSH increased with the slenderness of wool fiber when the length is approximately equivalent. Specifically, the DFE increased distinctly as the CSH increased. The pills weight of wool knitted fabric was in good agreement with the CSH, DFE.

The Relationship

The aims of this study were to identify the optimal combination of knitted fabric properties that influence the sensation of coolness and to ascertain the relationship between subjective and objective coolness measurements. Test fabrics included eight cool-touch nylon knitted fabrics and four other knitted fabrics. The physical properties and surface characteristics of the fabrics were assessed. Coolness sensation was determined by the Thermolabo II instrument to provide an objective measurement, expressed as Qmax. A forearm test and palm-of-hand test were used as subjective measurements. Pore volume ratio and geometric roughness had a significant effect on coolness sensation expressed via Qmax. Stiffness and weight influenced the forearm test. Pore volume ratio and the coefficient of steel–fabric friction affected the coolness sensation measured by the palm-of-hand test. Nylon/spandex (78/22) tricot was the coolest of all samples, such that its characteristics were thought to represent the optimal combination of knitted fabric properties for a cooling fabric, that is, a high and balanced stitch density of 150 × 130, light in weight of 161.4 g/m2, a pore volume ratio of 69.4%, medium geometric roughness, and a thin pliable knitted fabric. The objective measurements were highly correlated with the palm-of-hand test, but not with the forearm test because only the palm-of-hand test had a test set-up that was similar to the objective test. Although the objective and forearm test set-ups were only slightly different, coolness assessed with the forearm test was not correlated with coolness assessed with objective measurements.
