膨体羊毛与常规羊毛织物的热学性能对比

Comparison of fabrics' thermal properties between bulking wool and regular wool

测试分析了克重相同的膨体羊毛织物和常规羊毛织物的热学性能,发现膨体羊毛织物比常规羊毛织物的暖感大幅度增强、冷感大幅度减弱;在无风条件下,膨体羊毛织物的保温性明显优于常规羊毛织物;在有风条件下,膨体羊毛织物的保温性也优于常规羊毛织物,但是二类织物热阻的差异变小,说明膨体羊毛织物的挡风性不够好,应该与风衣或挡风里料等组合使用,同时得出有风条件下织物热阻与厚度、透气率的二元一次拟合方程。实验结果证实纺织品的性能不完全取决于纤维种类,而在很大程度上取决于制造技术。

This essay measures the fabrics＇ thermal properties between bulking wool and regular wool within the same grams per square meter, then finds that the warm-feeling of bulking wool fabric is stronger, and cool-feeling is weaker than regular wool fabric. Within double-board test, the heat resistant property of bulking wool is much better, and within single-board test the bulking wool fabric＇s heat resistant property is superior to regular wool fabric, but the difference between them diminishes. This fact reveals that wind resistant of bulking wool fabric is not so good, thus it should be utilized with lining. At the same time, a formula is concluded between the thermal property and thickness and air permeability. According to the results of the measurement, we can find that the properties of textile do not depend on fibers completely, and on account of the production technology on some level.
