Strength Distribution Analysis of Typical Staple Fibers

IntroductionThe mechanical properties of yarns are deter mined bytheir constituent fibers.Consequently,the strength offibers is an i mportant property in deter mining the finalquality of all textile products.Generally,it is al ways truethat the higher the strength of fibers,the higher thestrength of yarns and fabrics.However,because of the variation of fiber strength,the fibers within a yarn will not break at the same ti meunder a tensile load.In fact,break will take place at theweakest fiber…

Gray Synthetic Evaluation on Moisture Comfort of Sportswear Fabrics under the Condition of Heavy Sweating

Moisture and water transfer under the condition of heavy sweating are analyzed. Four different experiments are made to test moisture resistance, water-keep, wicking effect and drying ability of samples. Then gray analysis method is introduced to evaluate the comprehensive comfort of these fabrics. Result shows chemical fiber with high moisture transfer performance has advantage in water transfer and diffusion, which is suitable for human under the condition of heavy sweating. Though natural fiber can absorb moisture well, it cannot transfer fluid sweat. Therefore natural fiber fabrics such as cotton, wool are unsuitable to make functional sportswear.     

PREPARATION AND APPLICATION OF A NEW ANTIFELTING RESIN FOR WOOL FABRICS

In this paper,a new resin called Resin M for imparting antifelting properties to wool fabricshas been studied.Resin M may be used by aqueous oxidative/polymer technique.It is provedthat Oxidant A/Resin M treatment can satisfy the machine washable requirement formulated byI.W.S..Resin M is a good agent for antifelting treatment of wool fabrics with proper pretreatment.Oxidant A/Resin M treatment has little influence on dyeing and moisture adsorption properties ofwool fibers.The pilling resistance of the treated fabrics is higher than that of the untreated ones.The strength and the handle of the treated fabrics have little been changed.According to thescanning electron microscope observations,it is recommended that the polymer encapsulation ofindividual fiber also plays an important role in the felting resistance of the treated fabrics though itis well known that the shrink resistance of the treated fabrics is believed to be due to the binding offibers.

Principles and Chief Technologies in Developing Light-weighted Worsted Fabrics

More and more light-weighted fabrics are being required by the market, especially for the worsted manufacture. In the past, such fabrics are produced mainly through changing the structure of woven goods or by using finer yarns. But these possibilities are very limited. In this paper, new devices are discussed: (1) on the yarn level - to use single yarns instead of conventional doubled ones, to decrease number of fibers in yarn cross sections both during spuming and after finishing; (2) on the fiber level - to use finer fibers in blends with wool and modification of the wool fibers; (3) on the macromolecule level - to stretch the macromolecules in alpha keratin, to get super fine wool fibers.

Comfort of Light-weight Wool and Wool Blend Woven Fabrics

The comfort of the light-weight woven fabrics was investigated by conducting the wear trials under the controlled climatic conditions. The wear trial under the neutral environmental conditions showed that the lightweight wool and wool blend fabrics are generally less comfortable than the silk fabric, cotton poplin and polyester/cotton poplin fabrics tested in this study. The main shortcoming in terms of comfort for these lightweight wool fabrics is the prickle. Besides, the fabric softness was found to be a very important factor influencing the comfort of the clothing worn next to the skin.

PRIMARY APPLICATION OF THE WATER SOLUBLE POLYURETHANE (WPU) TO PROTEIN FABRICS

The primary application of the water soluble polyurethane (WPU) in protein fabrics was investigated. Both WCRA (wet crease recovery angle ) and DCRA ( dry crease recovery angle ) of silk fabrics finished with WPU were increased, and the other properties were only slightly influenced. As a formaldehyde - free silk finishing agent, WPU was proved to have a great future. The felting shrinkage ratio of wool fabrics treated by only WPU was reduced to 12.5% from 36.7%. On the basis of Oxidation/ Resin process, the felting shrinkage ratio of treated wool was 8.7%, and almost reached "Machine washable" level.

Study on the Factors to Influence Dynamic Heat - moisture Comfort of Summer Clothing Fabrics

In this paper, the factors to influence the dynamic heat - moisture comfort of summer clothing fabrics have been studied. It is pointed out that, when the wind speed outside is high, or the air permeability is very good, the sweat of human body will evaporate mainly through turbulent diffusion. Because of the rapid sweat evaporation, human body will feel cold, and then, the difference in temperature and humidity of the micro - climatic section will be very slight. On the contrary, when the wind speed outside is slow or the air permeability is unsatisfactory, the sweat of human body will evaporate mainly through molecular diffusion, and in this case, the humidity of the micro - climatic section will be depended on the hygroscopicity of the fabric, that' s to say, the better the hygroscopicity, the lower the humidity. It is difficult for pure wool fabric to loss heat because of its giving out much heat during the course of moisture - absorption in the initial stages of sweating. For pure polyester fabric,
