The Principle Of Non-woven Fabric Bags

The raw material for non-woven bags is polypropylene, while the raw material for plastic bags is polyethylene. Although the two substances have similar names, their chemical structures are very different. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so plastic bags take 300 years to decompose completely; However, the chemical structure of polypropylene is not strong, and the molecular chains can easily break, which can effectively degrade 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 is made without the need for textile processing and resembles non-woven fabric, also known as non-woven fabric. Because it only needs to orient or randomly support textile short fibers or long fibers to form a fiber mesh structure, and then use mechanical, thermal adhesive, or chemical methods to reinforce it. Most non-woven bags are made of spunbond non-woven fabric.
Simply put, non-woven fabric is not made up of interwoven and woven yarns, but rather fibers that are directly bonded together through physical methods. Therefore, when you take the adhesive scale from your clothes, you will find that it is impossible to pull out individual threads. Non woven fabrics break through traditional textile principles and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials.
