织物的透气性及透湿性测试重要性

2018-01-31 点击:

  分别针对整理后涤纶织物和非整理涤纶织物进行透气性及透湿性测试实验,结果表明:大部分非整理织物的透气性及透湿性均较好;而经过特殊整理的织物因不同的成膜整理剂呈现出不同的效果,如经过疏水性成膜整理剂整理后的织物其透气性及透湿性一般均较差,而经过亲水性成膜整理剂整理后的织物其透气性差,透湿性好。同时,经过亲水性成膜整理剂整理的织物因不同的整理方式可以呈现出不同的风格,如当亲水性成膜整理剂处理于织物组织结构之间时,此时织物可以呈现出亲水透湿型;而当其以涂层整理方式处理于织物反面时,此时织物可以呈现出疏水透湿型。

  Some enlightenment from the tests of air permeability and

  moisture absorption for fabrics

  Abstract: The article analyzes air permeability and moisture absorption of all kinds of fabrics, it points out: in most unfinished fabrics, the air permeability and moisture absorption are acceptable ;while the fabrics are pretreated by hydrophobic agent or hydrophilic agent show a distinctive tendency, the former have worse moisture absorption than the later, but both have poor air permeability. The different technology of processing hydrophilic fabric show different performance, the fabric with hydrophilic agent in fabric texture has hydrophilic and moisture absorption performance; while the agent was treated in the fabric back posses hydrophobic and moisture absorption performance.

  织物的透气性是指气体分子通过织物的性能,是织物透通性中最基本的性能,主要影响织物的穿着舒适性,如隔热、保暖、通透、凉快,以及织物的使用性能,如降落伞、安全气囊、船帆、热气球、热气艇等;而织物的透湿性是指湿汽透过织物的性能,又称透水汽性,是对人体散热发汗时维持人体产热和散热的热平衡能力[1]。因此对织物透气性和透湿性的认识和表征极为重要。
