Abstract: In order to study the heat-moisture comfort of fabric,11 kinds specifications of cut pile fabrics were knitted using moisture absorbent and dry fast ,low-elastic network polyester yarn. The effect of the wool length,under yarn feeding and linear density on the thermal-wet comfort propertie was investigated by experiment method.The relationship between structure parameters and fabric permeability quantity, wicking height, heat preservation rate,heat transfer coefficient was found through the regression analysis.The results show that the structural parameters of wool length,under yarn feeding and linear density have significant influence on the heat -moisture comfort of cut pile fabric.The wool length was significant influence on permeability and thermal insulation.There were negative and positive correlation between wool length of cut pile fabric and air permeability, clo value respectively.The backing yarn sending has a positive correlation with moisture permeability,its correlation coefficient was 0.9973.

Key words: weft knitting, cut pile fabric, structure parameter, thermal-moisture comfort, regression analysis
