摘要:

为探明含水率不同织物与皮肤间的动摩擦力变化趋势,选取18种机织面料和9种针织面料与同一女性青年志愿者的前臂内侧皮肤进行摩擦实验,利用织物皮肤摩擦测试仪测试湿态条件下织物与皮肤间的动摩擦力。针对不同湿态条件的织物试样,采用完全浸润织物后悬挂自然晾置的方式,以织物的含水率定量表征织物的润湿程度。结果表明:相同原料的织物和皮肤间的动摩擦力变化趋势相似,反之亦然;织物含水率在10%~60%的范围内,随着织物含水率的增大,不同原料的织物与皮肤间的动摩擦力变化普遍存在先增大后减小的趋势;湿态条件下织物和皮肤间的动摩擦力达到峰值时,织物的含水率与纤维的公定回潮率存在正相关关系。

Abstract:

In order to investigate the relationship between fabric hygroscopicity and the dynamic friction between fabric and skin, 18 kinds of woven fabrics and 9 kinds of knitted fabrics were chosed to carry out the friction experiment with the same female volunteers’ inner forearm skin. The dynamic friction between fabric and skin were tested by fabric-skin friction tester under wet condition. According to the fabric sample under different wet conditions, the samples were completely infiltrated and then hung naturally in order to drying. The moisture content was used to quantitatively represent the wetting degree of the fabric. It was found that the dynamic friction change trends between the same raw material fabrics and skin were similar, and vice versa. The dynamic friction change trends between different kinds of fabric and skin generally increased and then decreased along with the rising of the fabric moisture content from 10% to 60%. It’s a positive correlation between fiber moisture regain and the fabric moisture content at the peak dynamic friction between fabric and skin under wet condition.
