Principle Of Non-woven Bags

Non-woven fabric is a kind of non-woven fabric. It is a new type of fiber product with soft, breathable and flat structure formed by directly using polymer slices, short fibers or filaments through various fiber web forming methods and consolidation technologies. Advantages of non-woven bags compared to traditional plastic bags: non-woven bags are cheap and good, environmentally friendly and practical, widely used, and have prominent advertising positions. Suitable for all kinds of business activities and exhibitions and trade fairs, it is an ideal advertising promotion gift for enterprises and institutions.
The raw material of non-woven bags is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, they are very different in chemical structure. The chemical molecular structure of polyethylene has a very strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose completely; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, so it can be effectively degraded, and enter the next environmental cycle in a non-toxic form. A non-woven bag can be completely decomposed within 90 days.
Non-woven fabric is a product that does not require a textile process to be made into a cloth-like non-cloth product, also called non-woven fabric. Because it only needs to orient or randomly support textile staple fibers or filaments to form a fiber mesh structure, and then use mechanical, thermal bonding or chemical methods to reinforce it. Most non-woven bags are made of spunbond non-woven fabrics.
Simply put: non-woven fabrics are not interwoven and knitted together by yarns one by one, but the fibers are directly bonded together by physical methods. Therefore, when you get the sticky scale in your clothes, you will find that you can't pull out a single thread. Non-woven fabrics break through the traditional textile principles and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple sources of raw materials.
