Why is non-woven fabric an environmentally friendly material?

Update:14 Dec 2020
Non-woven fabric is a new type of fiber product with soft, breathable and flat structure. The advantage is that it does not produce fiber debris, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it has a cotton feel, compared with cotton fabrics. , Non-woven bags are easy to shape and cheap to make.
It is a new generation of environmentally friendly materials, which are water-repellent, breathable, flexible, non-combustible, non-toxic, non-irritating, and rich in colors. If the material is naturally decomposed outdoors, its longest life span is only 90 days, and it decomposes within 8 years when placed indoors. It is non-toxic, odorless, and contains no leftover substances when burned, so it does not pollute the environment, so environmental protection comes .
In terms of environmental protection, the raw material of most non woven fabric for face mask currently 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 decompose, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be 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 disposal is only 10% of that of plastic bags.
The disadvantage of non-woven fabrics is that they have poor strength and durability, and cannot be cleaned like other fabrics. Because the fibers are arranged in a certain direction, they are easy to split from the right-angle direction.
