摘　　要：用液态水分管理测试仪MMT测试CoolMax织物及经TPU涂层处理、层压TPU透湿薄膜处理织物的内外表层的浸湿时间、吸收速度、最大浸湿半径、水分传递速度、单向传递能力和整体液态水分管理能力等指标,以研究它们的防水透湿行为。结果表明:经过透湿和TPU涂层处理的锦纶机织物的透湿性能和水分扩散性能较差,但其内表面均具有较强的防水性能;经TPU涂层处理的斜纹锦纶机织物相对于平纹织物具有较好的湿传递能力;不同的织物表面处理方法对织物动态水分传递能力的影响较为明显。此外,还探讨了CoolMax织物及经过高分子TPU涂层、层压TPU薄膜处理的功能性防水透湿织物的应用以及改进方式。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. TPU 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.
