What is the principle of non-woven fabric bags

Non woven fabric is a type of non-woven fabric that directly utilizes polymer chips, short fibers, or filaments to form a new type of fiber product with soft, breathable, and flat structure through various fiber mesh forming methods and consolidation techniques. Compared to traditional plastic bags, non-woven fabric bags have the following advantages: they are cost-effective, environmentally friendly, practical, widely used, and have a prominent advertising position. Suitable for various business activities and exhibitions, it is an ideal advertising promotion gift for enterprises and institutions
The raw material of non-woven fabric bags is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are very different. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose completely; 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 does not require the spinning process to be made into a non-woven fabric, also known as non woven fabric. Because it only needs to orient or randomly support textile short fibers or filaments to form a fiber network structure, and then use mechanical, thermal adhesive, or chemical methods to reinforce it. Most non-woven bags are made of spunbonded non-woven fabric.
Simply put, non-woven fabrics are not made by interweaving and weaving yarn after yarn, but by directly bonding fibers together through physical methods. Therefore, when you get the adhesive weight in your clothes, you will find that it is impossible to pull out thread after thread. Non woven fabrics break through traditional textile principles and have the characteristics of short process flow, fast production speed, high yield, low cost, wide use, and multiple sources of raw materials.
Laminated non-woven fabric bag, the product adopts casting method, and the composite is firm. During the composite process, it does not stick, has a soft feel, no plastic feeling, and no skin irritation. It is suitable for the production of disposable medical sheets, bed sheets, surgical gowns, isolation suits, protective clothing, shoe covers, and other health protection products; This type of fabric bag is called a laminated non-woven fabric bag.
