Three types of nonwoven fabrics were chosen, including pure polypropylene SMMS nonwoven materials, pure polypropylene spunbond nonwoven materials and polyester/viscose 70/30 spunlaced nonwoven materials. Testing indexes consisted of the test of the basic structure characteristics, permeability, moisture vapor transimission and thermal properties. After analysising of the results, we understood that, for pure polypropylene SMMS nonwoven materials, pure polypropylene spunbond nonwoven materials and polyester/viscose 70/30 spunlaced nonwoven materials, their permeability and moisture vapor transimission decrease with the increasing volume density. Their thermal properties depend on fabric thickness and volume density. In practice, only when proper manufacturing process, raw material, area density and volume density are selected according to fabric end-uses and the thermal and moisture comfort properties, can we produce appropriate nonwovens for apparel end-uses.
