摘要
为提高面料的凉感效果以及解决现有面料凉感测试仪器无法检测水对面料凉感性能影响的问题,利用高密度聚乙烯纤维为圈组织、纯棉靛蓝纱为地组织开发了2款针织牛仔凉感面料,并对面料的凉感性能、吸湿快干性能、抗紫外线性能等进行了检测;搭建织物凉感性能可视化检测平台,用带有一定温度的水滴代替汗液,对面料吸湿后凉感性能的变化规律进行了探究。结果显示:面料吸湿以后导热能力显著提升,降温效果明显,面料的稳态凉感性能得到提升;水分对面料稳态凉感的影响大于纤维的导热性能,面料的吸湿性能越好,其稳态凉感效果就越好;水滴被样品面料吸收以后,会在面料的表面扩散成有规律的温度分布区域。
In order to improve the cooling effect of fabrics and solve the problem that the existing fabric cooling test instruments can not detect the influence of water on the cooling performance of fabrics,two knitted denim cooling fabrics were developed by using high-density polyethylene fiber as loop structure and pure cotton indigo yarn as ground structure,and the cooling performance,moisture absorption and quick drying performance and UV resistance of the fabrics were tested.The visual detection platform of fabric cooling performance was built,and the change of fabric cooling performance after moisture absorption was explored by using water droplets with a certain temperature instead of sweat.The results showed the thermal conductivity of the fabric is significantly improved,the cooling effect is obvious,and the steady-state cooling performance of the fabric is improved.The influence of moisture on the steady-state cool feeling of fabric is greater than that of fiber thermal conductivity.The better the moisture absorption of fabric,the better the steady-state cool feeling effect.After the water droplets are absorbed by the sample fabric,they will diffuse into a regular temperature distribution area on the surface of the fabric.
