灰色理论在麻织物热湿舒适性研究中的应用

Application of gray system theory in evaluation of thermal and moisture comfort of bast fiber fabrics

利用灰色理论评价麻织物的热湿舒适性,通过测试不同规格麻织物的传热、透气、导湿和吸湿性能,用灰色关联度分析法与蚕丝织物各热湿性能指标构成的参考数列进行比较,排出了夏季服用麻织物热湿舒适性能的优劣次序,为热湿舒适性能的研究提供了理论依据。实验证明:在高湿与低湿状态下,厚度和总紧度对织物的透湿性能产生的影响是不同的;在低湿条件下,紧度产生的影响效果比厚度大,而在高湿条件下,厚度产生的影响因素占据主导地位。

Use of gray system theory in evaluation of thermal and moisture comfort of bast fiber fabric is introduced. The thermal transmittance, air permeability, moisture vapor transmission （MVT）, and hygroscopicity of bast fiber fabric with different specifications are tested, and their thermal and moisture transmitting properties are compared with those of silk fabrics through gray correlation analysis and the thermal and moisture transmitting properties of the summer bast fiber fabrics are listed in the order from good to bad, thus providing a theoretical basis for investigation of thermal and moisture comfort of fabric. The experimental results show that the influence of fabric thickness and tightness on MVT varies with humidity. In low humidity, fabric tightness is more important than thickness, and vice versa in high humididy.
