The thermal and moisture comfort of inovational natrural hygroscopic fibers
The thermal and humidity comfort of ten kinds of knitting fabric made of innovational natural hygroscopic fibers and blending is studied in this paper using a new method and technique. The trials are performed in a climatic chamber at 26℃, RH65％ by alternating periods of exercise. The subjective evaluation data of comfort sensations are collected by ranking on a modified and developed rating sheet. A new technique, infrared image is used to measure the thermal and humidity dynamic transfer through clothing assembles during trials. The surface of testing clothing are classified into 16 sections based on the temperature varying during exercise, and the thermal and humidity comfort of the clothing, which combines thermal sensations, clamminess and surface temperature, is studied in order to conclude optimization assemble of various hygroscopic fibers, and the optimizing design of sports clothing is proposed. Depended on the data and basic theory of thermal and humidity transport the boundary conditions equation is extended. The extended boundary conditions equation is deducted, which is applied in certain condition when the water content of a fabric is greater than the maximum equilibrium regain of its fibers, moisture exchange is evaporation condensation process, and the air layer of clothing occurred because of lower ambient air velocity.
