Design and performance of multi component nonwoven thermal insulation material

在保暖材料向复合型多功能发展的趋势下，设计探究了一种多组分非织造保暖材料。将不同比例的木棉、远红外三维卷曲中空涤纶、ES纤维混合，通过非织造技术加工成非织造保暖材料。对其面密度、厚度、远红外辐射温升、保暖性、蓬松度与回复率、透气性、透湿性进行了测试分析。测试结果显示，木棉／远红外三维卷曲中空涤纶／Es40／40／20保暖材料的综合性能最好，克罗值为1．54℃·m^2／W，远红外辐射温升值2．7℃，透气率1608．7mm／s，透湿率98．94g/（m^2·h），蓬松度218．33cm^3／g，回复率86．90％。

In view of the tendency of thermal insulation material developing into composite multifunctional material, a kind ot multi-component nonwoven thermal insulation material is designed and researched. The kapok fibers and three-dimensional crimp hollow polyester fibers and ES fibers at different ratios are blended to form nonwoven composite thermal insulation material by nonwoven processing method. Their surface density, thickness, temperature-rise under far infrared radiation, thermal resistance, fill power, compressive-resilient performance, air permeability as well as moisture permeability are tested and analyzed. The results show that the kapok/ far infrared three-dimensional crimp hollow polyester fiber/ES of 40/40/20 has the best comprehensive performance with Clo value of 1.54℃·m^2/W, far infrared radiation temperature-rise of 2.7℃, air permeability of 1 608.7 mm/s, water vapor transmission rate of 98.94 g/（ m^2·h）, bulk density of 218.33 em3/g and recovery rate of 86.90%.
