Are non-woven fabrics cloth? Why is it called "non-woven"?
Polypropylene is the raw material of non-woven fabrics, while polyethylene is the raw material of plastic bags. Although the names of the two substances are similar, their chemical structures are quite different. Polyethylene is very stable and difficult to degrade, so it takes 300 years for plastic bags to decompose. Polypropylene has a strong chemical structure, which can easily break the molecular chain, so it can be effectively degraded, and in the non-toxic form into the next environmental cycle, a non-woven bag can be completely decomposed in 90 days.
