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

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.
