Non-woven felt is a kind of non-woven fabric, which directly uses high polymer chips, short fibers or filaments to pass the fibers through airflow or mechanical netting, and then through hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishing. Formed non-woven fabric. The new fiber product with soft, breathable and flat structure has the advantages of no lint, strong, durable, silky soft, and a cottony feel. Compared with cotton, the non-woven bag is easy to form, and The cost is cheap.
In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, and the raw material of the plastic bags is polyethylene. Although the two substances have similar names, the chemical structure is quite different.
The chemical molecular structure of polyethylene has considerable stability and is extremely difficult to degrade, so it takes 300 years for the plastic bag to be decomposed.
The chemical structure of polypropylene is not strong, the molecular chain can be easily broken, so that it 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, the non-woven shopping bag, printed non-woven felt sheet can be reused more than 10 times, and the environmental pollution degree after disposal is only 10% of the plastic bag.
