7 Good physical properties
It is made of polypropylene spun yarn directly spread into a net and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional and the strength is similar in the longitudinal and transverse directions.
8 Environmental protection
In terms of environmental protection, the raw material of most of the non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the pollution to the environment after being discarded is only 10% of that of plastic bags.
1 Compared with woven cloth, the strength and durability are poor.
2 Can not be washed like other fabrics.
3 The fibers are arranged in a certain direction, so it is easy to split from the right angle. Therefore, the improvement of the production method mainly focuses on the improvement of preventing splitting.
