Cotton non-woven fabrics can be degraded. The raw material of most non-woven fabrics is polypropylene. Its chemical structure is not strong. The molecular chain is easily broken and degraded. It enters the environmental cycle in a non-toxic form. A non-woven shopping bag It can be completely decomposed within 90 days. The degree of pollution to the environment after being discarded is also relatively light.

Non-woven fabric is a kind of non-woven fabric. It is a non-woven fabric formed by directly using polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement. fabric. According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc., which are not easy to degrade. It is estimated that it will take hundreds of years to decompose.
