Abstract:

A self-made fabric testing instruments using resistance theoty was developed to track the moisture transmission and perspiration across the fabrics against the root problem of low level of automation conditions and measuring precision. 11 pieces of Coolmax polyester knitted fabrics were tested by the self-made testing instrument, the classic capillary effect method and the weighing method. Results show that the self-made fabric testing instruments can test moisture transmission and perspiration of fabric with good repeatability. The sweat transmitting coefficients of multiple directions are more efficient assessment indicators than those of latitude and longitude. The fabric drying time tested by the self-made testing instruments is extremely precise, which can substitute the drying time indicators of classic weighing method. And significant differences exist among different directions for drop moisture transmission and perspiration across fabrics for big range ratio.

Key words: knitted fabric, moisture transmission and prespiration, wicking property, drying property
