【摘要】 为探究针织内衣织物接触冷暖感与织物结构及力学性能的关系,采用KES-F7精密瞬间热物性测试仪测试14种针织内衣织物的最大瞬态热流量。从织物密度、织物厚度等结构参数以及织物相关力学性能等方面分析其影响因素。结果表明:织物结构越紧密,织物中静止空气含量越低,皮肤与织物接触冷感强烈;织物表面越光滑,皮肤与织物接触面积越大,接触冷感强烈;织物厚度越大,皮肤与织物接触暖感强烈。织物的结构参数影响织物中静止空气含量,从而对织物接触冷暖感产生影响。由织物最大瞬态热流量与织物力学性能参数相关性分析可知,减小织物与皮肤的接触面积,提高织物的蓬松性,有利于增强织物的接触暖感。更多还原

【Abstract】 In order to explore the relationship between warm-cool feeling and the structure and mechanical properties of fabrics. The maximum transient thermal flow of 14 knitted underwear fabrics were tested by the KES-F7 tester. The influence factors were analyzed from the perspective of fabric density,fabric thickness and fabric mechanical properties on knitted fabrics contact thermal sensation.The results show that with tight fabric structure,the still air content in the fabric will be lower,which would lead to the greater maximum transient heat flow of the fabric and stronger transient cool feeling.Fabric surface is smoother,skin and fabric contact area is larger,cool feeling will be stronger. The thicker of fabric thickness,the warm feeling will be intense. Correlation analysis of fabric maximum transient heat flow and mechanical property parameters shows that it is conducive to enhancing the fabric transient warm feeling by reducing the fabric and skin contact area and improving the fabric bulkiness.更多还原
