Dynamic Analysis on Thermal and Humidity Properties of Knitted Fabrics
A dynamic method was investigated to measure thermal and humidity properties of cotton fabrics. In order to simulate ambient air condition, testing sample was rotated during measuring process, and surface temperature and humidity on fabrics in various simulated wind speeds (rotation speeds) and different moisture regains was studied. As a result, in the process of moisture vapor releasing under dynamic ambient environment, a corresponding curve of the surface humidity increased in first stage, then keep an almost constant humidity values, and decreased at last, on the contrary, related curve of surface temperature decreased at the beginning, then held a stationary temperature value in the second phases, and finally increased as time passed. The faster speed of ambient simulated air current (rotation speed), the more time related surface temperature and humidity last.
