Introduction to the Characteristics of Non-woven Fabrics

Non-woven fabric is a kind of non textile fabric. It is a kind of non-woven fabric that directly uses polymer chips, staple fibers or filaments to form fibers through air flow or mechanical netting, then through spunlace, needle-punching, or hot-rolling reinforcement, and finally off line treatment. The advantages of the new fiber products with soft, breathable and flat structure are that they do not have fiber chips, are strong, durable, silky and soft. They also have the feeling of cotton. Compared with cotton fabrics, non-woven bags are easy to form and cost less.

In terms of environmental protection, most of the raw materials used for non-woven fabrics are polypropylene, while the raw materials for plastic bags are polyethylene. Although the names of the two materials are similar, their chemical structures are quite different. The chemical molecular structure of polyethylene is quite stable and very difficult to degrade, so it takes around 300 years for plastic bags to decompose; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, so it can be effectively degraded, and in the non-toxic form into the next environmental cycle, a non-woven fabric. Shopping bags can be completely decomposed in 90 days. Moreover, the non-woven shopping bags can be reused more than 10 times, and the environmental pollution degree of the discarded bags is only 10% of that of the plastic bags.
