三叶形涤纶织物的吸湿性能

为了研究分析异形涤纶织物的吸湿性能，本文选取三叶形涤纶织物和普通涤纶织物，采用自制的实验装置，模拟不同温度、湿度条件，测定了三叶形涤纶织物和普通涤纶织物的吸湿特性和芯吸效应。分析了环境温度、湿度对织物吸湿性能的影响；探讨了织物的经纬向芯吸高度及芯吸速率。研究结果表明：织物的含水率随温度升高而减小，随湿度的增大而增大；三叶形涤纶织物的吸湿速率和平衡含水率都比普通涤纶织物大，特别是低温高湿情况下优势更明显；三叶形涤纶织物的液态水传递性能优于普通涤纶织物，芯吸速率比普通涤纶织物高，经向织物芯吸能力优于纬向织物芯吸能力。

Study onmoisture absorption performance of trilobal polyester fabric

Abstract In order to study the process of moisture absorption of profiled polyester fabric，this paper selects trefoil polyester fabric and ordinary polyester fabric，uses homemade experimental apparatus，simulates different temperature and humidity conditions and measures the moisture absorption characteristics and wicking effect of the trilobal polyester fabric and ordinary polyester fabric．Analyzing the environmental temperature and humidity how to affect the fabric moisture absorption performance; and Exploring the warp / weft of the fabric how to effect wicking height and wicking rate．Research results show that：The fabric moisture content decreases with temperature rise，along with the increasing of humidity；the moisture absorption rate and equilibrium moisture content of trilobal polyester fabric is larger than that of ordinary polyester fabric，especially in low temperature and high humidity conditions，the advantage is more obvious；the liquid water delivery performance of trilobal polyester fabric is better than that of ordinary polyester fabric，the wicking rate is higher than ordinary polyester fabric，warp fabric wicking ability is better than that of weft fabric．
