竹原纤维织物热湿舒适性的灰色关联评价模型

Model of thermal and moisture comfort evaluation of bamboo fiber fabric based on grey correlation degree

为了采用常规测试方法对竹原纤维织物的热湿舒适性进行客观、全面地评价,根据织物热湿传递机制,对竹原纤维织物的透气量、透湿量、经纬向芯吸高度、保温率、传热系数指标进行测试,以客观表征织物的热湿性能。同时,采用主观评价法得到织物热湿舒适性的主观数据。运用灰色关联度法,将主客观评价结果结合起来处理,确定出各项客观热湿性能指标对主观评价值的权重系数,建立对竹原纤维织物热湿舒适性评价模型,经t检验判断该评价模型有效。

For carrying out an overall and objective evaluation of thermal and moisture comfort of bamboo fiber fabric through common methods,the air permeability quantity,water vapor transmission quantity,wicking height（warp weft）,warmth retention rate and heat transfer coefficient of bamboo fiber fabric were tested based on the mechanism of thermal and moisture transmission in order to characterize the thermal and moisture property of the fabric objectively.Thermal and moisture performance data of the fabric were obtained through subjective assessment.All of the values were processed by grey correlation,and weight coefficients of each thermal and moisture item were determined,then a model of thermal-moisture comfort evaluation was developed.Thettest shows that the model is practical.
