Abstract:

The moisture transfer principles of CoolMax fabric, TPU coated fabric, and TPU film laminated fabric were tested using the moisture management tester ( MMT ) in terms of wetting time of inside and outside surfaces of the fabrics, absorption rate, maximum wetted radius, moisture transfer speed, one way moisture transfer ability, and overall moisture management ability etc. The results indicated that TPU coated woven polyamide fabric showed relatively lower moisture permeability and moisture spreading ability, but its inside surface exhibited better water-proofing power. TUP coated twill woven polyamide fabric had better moisture permeability than its plain fabric. In addition, the impact of different surface treatments on the moisture management ability of fabrics is obvious. Applications and modified way of the above fabrics were discussed as well.
