This document mainly studied the effect of Sorona fiber content and fabric structure on the wearingcharacteristicsofSoronacottonblendedseamlessknittedfabric. In the experiment, three different kinds of stitch structures and ratios of Sorona/cotton were designed and nine Sorona/cotton blended seamless knitted fabrics were knitted. And then, breaking elongation, rigid flexible, crease recovery, pilling resistance, hygroscopicity and air permeability of the nine seamless knitted fabrics were tested and analyzed. The result showed that with the increasing of Sorona fiber content, the properties of Breaking elongation, rigid flexible, crease recovery and pilling resistance of the Sorona/cotton blended seamless knitted fabrics had and a certain of improvement, however the hygroscopicity and air permeability decreased.

Weft Knitted Fabric

The fact that weft knitted fabrics has a stretchable, 3D, porous and interlocking structure makes them unique when manufactured from high performance fibers. Knitted fabrics with different architectures exhibit different properties. Different loop forms like tuck and skip stitches with various loop lengths reveal different physical and mechanical properties. Literature review indicated that wisely arrangement of tuck stitches within the pattern repeat alter the weft-knitted fabric structure from natural and synthetic fibers. Therefore, we studied the effect of number and location of tuck stiches on air permeability of weft-knitted fabrics from glass yarn. Single-bed, flat weft knitting machine was used to knit fabrics with different architectures from three-ply glass yarn. The nominal single-end count of used E-glass yarn was 136 tex. It is anticipated that the number and location of tuck stitches within knit pattern effect physical and air permeability properties of weft-knitted fabrics from glass yarn.

Most of the time, a certain degree of stretch prominently and incrementally occurs in intimate wear, leisure wear, sportswear, medical textiles etc., during their action. Variations in the stretch gradient would definitely cause changes in the air permeability of knitted fabrics. The influence of variables such as loop length, the presence of an elastomeric component and fabric structure on the air permeability of cotton single jersey and pique knitted fabrics in a stretched state was critically analysed. In this work, changes in the air permeability of cotton jersey samples with and without elastomer were investigated and reported by keeping the samples in static up to an incremental stretch of 40% at a rate of 10% of the stretch gradient, in a dry relaxed state, wet relaxed state and fully relaxed state.

The present study deals with the optimization of multiple quality parameters of single jersey and 1×1 rib knitted fabrics using the desirability function approach. Comfort properties such as air permeability, thermal conductivity and safety properties such as UV protection are combined to yield an ‘overall desirability’ varying from zero to one. The overall desirability has been maximized versus target values for air permeability, thermal conductivity and UV resistance. Experimental validation confirms that the proposed method can be used to design a knitted fabric with desired comfort and UV resistance characteristics.

An instrument is described for the measurement of shear in knitted fabrics under conditions of constant tension and “equal length of side.” Shear hysteresis loops were obtained for a series of wool plain-knitted fabrics of different tightness factors. Typical curves and fabric parameters (shear rigidity and coercive shear force) are presented for the fabrics tested in two states of relaxation using several values of applied tension. The results have been analyzed statistically and a simple friction-elastic rheological model of the shear behaviour is examined. This model is interpreted in terms of the knitted fabric structure and the changes that occur when a shear deformation is applied. Relaxation was found to reduce the values of both the shear rigidity and the coercive shear force. The effect of tension was investigated, and suitable levels of tension are recommended for testing knitted fabrics in shear.

Warp Knitted Fabric

Consumer points of view determine economical value of fabrics. Fabric luster plays a momentous role in attracting people's attention, especially for clothing and domestic purposes. Luster is defined by intensity of both specular and diffuse light reflection off of a surface. There are various methods for measuring surface luster. Gloss. Luster is described as the ratio of specular reflection in one angle to diffuse reflection in another angle. Two-bar warp knitted polyester fabrics such as Tricot, Locknit, Satin, reverse Locknit and Sharkskin in three different densities were provided. A mini gloss apparatus was applied to measure fabric specular reflection in the angle of sixty degrees, before and after disperse dying with different colors of white, blue and yellow. Results suggest that luster is a function of knitted fabric type, color and density. Enhancement of technical back luster resulted from longer underlap of the front bar. However, it did not change the technical face luster significantly. Density increased in all knitted fabrics and caused the luster to decrease. Dark color fabrics showed lower luster compared to light ones.

Warp Knitted Fabric

In recent years, as improvement of human living life, people begin to focus on themselves health. It is certain that bamboo charcoal has many properties, including water purification, deodorization, anion release and far-infrared ray radiation. This study aims to prepare PET/BC warp-knitted fabric composed of polyester yarn (PET) as warp yarn and bamboo charcoal polyamine yarn (BC) as weft yarn using Velcro Crochet Machine. Afterwards, air permeability, elastic resilience and far-infrared ray emissivity of resulting knitted fabric were discussed by changing weft yarn type. Result shows that, for knitted fabrics, weft yarn type cannot affect the elastic resilience; yet PET weft yarn makes air permeability decreasing.

This paper deals with thermo-physiological and sensorial comfort properties of knitted fabric samples manufactured from standard polyester (PET) and Coolmax (multi-lobal PET fiber) yarn by The Lycra Company, Wilmington, DE/USA. 18 knitted fabric samples were prepared by using PET and Coolmax. These samples were tested for qmax property related to warm/cool feeling, water-vapor transmission rate and air permeability. The results were analyzed statistically, and it was shown that fabric material used yarn to manufacture knitted samples, i.e. PET and Coolmax, has a significant effect on qmax, water-vapor transmission rate and air permeability of knitted fabric samples used in this study.

Comparative Information

The present study investigated the air permeability of three representative sportswear brands products (OUDIKE, NIKE and an unknown brand bought from the boutique) in Hong Kong marketplace. It was found that NIKE sportswear had the highest air permeability (0.23kPa*s/m) among the samples, which indicates that it allows more air flow passing through the textile and provides good comfort property to wearer, while OUDIKE samples showed the lowest air permeability in capacity (0.08kPa*s/m). The fiber content and fabric structure may be the reason that affects the air permeability. This study would provide a comparative information about air permeability property of the mainstream sportswear brands product in Hong Kong market.

Abstract Knitted fabrics have excellent comfort properties because of their typical porous structure. Different comfort properties of knitted fabrics such as air permeability, thermal absorptivity, and thermal conductivity depend on the properties of raw material and knitting parameters. In this paper, an investigation was done to observe the effect of yarn count, loop length, knitting speed, and yarn input tension in the presence of two uncontrollable noise factors on selected comfort properties of single jersey and 1×1 rib knitted fabrics using the Taguchi experimental design. The results show that yarn count and loop length have significant influence on the thermo-physiological comfort properties of knitted fabrics.
