The difference between PP non-woven and PET non-woven fabric

Non-woven fabric and nonwoven fabric, nonwoven or call. It is a kind of don't need to be formed by spinning weaving fabric, just short textile fiber or filament for directional or random supporting columns, form a fiber network structure, and then we used mechanical, thermal or chemical methods such as solid. Nonwovens break through the traditional principle of textile and a short process flow, production speed, high output, low cost, wide application, raw material source, etc. The most common is PET non-woven, PP non-woven fabric and then the difference in what way? One, different raw material: PP non-woven material is polypropylene, polypropylene fiber. PET non-woven material is polyester, polyester fiber. Second, high temperature resistant different: PP high temperature at 200 degrees, and PET high temperature at 290 degrees, PET high temperature more than PP. Three, the environmental protection point of view, PP more decomposition, decomposition cycle is short, the PET will be expected to very long period of time. Fourth, the tension, tension, bearing force, the same gram weight, PET is bigger than the PP. Five, the PP can be recycled recycling of waste materials, and PET cannot be recycled, so PP costs are lower.
