高透聚氨酯薄膜层压罗纹针织物服用性能研究

以2+2双罗纹针织物、热熔胶TPU和高透PU膜为原材料,采用层压复合的方法制备防水透湿复合织物,分析双罗纹针织物、高透PU膜及复合织物的拉伸性能、悬垂性、透气性,以及防水透湿效果,并通过改变TPU用量、温度及复合压力探讨对复合织物各项性能的影响。研究结果表明:双罗纹针织物与PU膜复合后,复合织物的强伸性有所提高,但悬垂性有所降低,防水效果明显比双罗纹针织物要好,透湿、透气效果比高透PU薄膜小一些。综合而言,当TPU用量为32 g/m2,复合压力为8 MPa,复合温度为80℃时,复合织物的复合效果最好。

Evaluation of moisture management properties on knitted fabrics

In order to determine the effect of raw material, weave type and tightness on liquid absorption and transmission which is an important factor in the perception of people’s clothing comfort, knitted fabrics made of cotton, viscose and polyester yarns, which had single jersey, 1?×?1 rib and single pique weave type, had three different tightness as tight, medium and loose, were produced. Moisture management tester (MMT) was used for multi-dimensional liquid transport of the fabrics produced. As a result of the study, it is observed that polyester fabrics had higher OMMC values than those of cellulosic-based fabrics. Regarding the effect of tightness, liquid transport has decreased with increasing tightness in general. Weave types examined in this study, were not as strong as raw materials and tightness and did not have such a significant effect.

Thermophysiological comfort properties of selected knitted fabrics and design of T-shirts

Thermal comfort is one of the most important components of comfort which shows physiological, psychological, and physical harmony between human body and environment. The heat and moisture transfer capacity of fabric from skin to environment affects the thermal comfort of garments. The transfer capacity depends on the characteristic features of raw materials and fabric structural properties. In this study, it is aimed to determine the advantages of knitted fabric types, taking into account the environmental condition and activity level by measuring the thermal comfort properties such as air permeability, wicking, moisture management, thermal and water vapor resistances. Two knitted structures composed of tuck and float combinations and six raw materials were chosen for the fabrics produced. According to the measurement results, the polyester and cotton/Coolmax fabrics with float stitches have had good liquid moisture transport properties. Besides, high air permeability and low water vapor resistance have been obtained in viscose and Tencel LF fabrics with tuck stitches. On the basis of the results obtained in this investigation, and taking into consideration thermal behavior of human body, four women’s and five men’s T-shirts are designed. These T-shirt designs may be helpful for further approaches on the optimization of thermal comfort for sports activities in hot environment.
