Abstract:

The phenolic fiber fabrics and the flame retardant cotton, aramid 1313 and polyimide fabric which are commonly used in the fire-fighting suit field were taken as research objectives with a view to understand the thermal-moisture comfort of phenolic fiber fabrics and apply it in the fighting field. The heat insulation, thermal insulation, moisture permeability, air permeability and water permeability of fabrics was tested, and the thermal-moisture comfort of fabrics with same weight and different kinds were studied. By using the gray cluster analysis, the integrated evaluation of thermal-moisture comfort of the four fabrics under different environmental conditions were conducted.The results show that：under the high temperature conditions, the phenolic fiber fabric has good thermal-moisture comfort, the polyimide fabric and flame retardant cotton fabric are the second, and the aramid 1313 fabric is the worst：and under the low temperature condition, the phenolic fiber fabric has good thermal-moisture comfort, the polyimide fabric is the second, and the flame retardant cotton fabric and the aramid 1313 fabric are the worst.

Key words: phenolic fiber fabric, thermal-moisture comfort, thermal insulation, moisture permeability
