Abstract: For carrying out an overall and objective evaluation of wet comfort of knitted fabric through a simple and easy testing method,four indexes,i.e.,velocity constant of moisture absorption,moisture transmission rate,air permeability,drying rate were selected based on the mechanism of wet transmission for testing the wet comfort of the light weight knitted fabric under slightly sweated condition.Then fuzzy evaluation model was established,and each index could be evaluated by weighted average synthetic evaluation function.Here,weight coefficient was determined by maximum deviation,and all calculation was completed by MatLab program.
