Study on Main Factors Impact on Heat-moisture Comfort of Knitted Fabric

This article makes the heat-moisture comfort experiments of regenerated fiber fabric, such as tencel, modal and bamboo fabric, which compare with cotton fabric. Make the analysis that the thermal resistance of tencel and bamboo fabrics are less than cotton fabrics. For the warm-cool feeling of these fabrics, the modal fabric is strongest and stronger than tencel fabric, the bamboo fabric is the second and the cotton fabric is the lowest. The moisture transfer properties of bamboo fabric is good, which is close to the cotton in sweating condition. The water permeability of cotton is the best while modal and tencel are worse than bamboo fabric. The air permeability has less effect on the types of fiber. Then, use the SPSS software to analyze the impact factors that may affect heat-moisture comfort of knitted under wear. In the end, we make out conclusion that the main factors which influence heat-moisture comfort of knitted underwear are moisture absorption performance, water vapor permeability, fabric thickness, cloth structure, tightness and the warm-coolfeeling.
