The principle of non-woven bags
The nonwoven fabric is a nonwoven fabric which utilizes high polymer chips, short fibers or filaments to form new fibrous products with a soft, breathable and planar structure formed by various web forming methods and consolidation techniques. Non-woven bags compared to the advantages of traditional plastic bags: non-woven bags cheap, environmentally friendly and practical, widely used, there are prominent advertising position. Applicable to all kinds of business activities and exhibition trade fairs, enterprises and institutions is the ideal advertising promotional gifts.
Non-woven bags of raw materials are polypropylene, and plastic bags of raw materials is polyethylene, although the two substances similar names, but the chemical structure is very different. Polyethylene chemical structure has a very strong stability, very difficult to degrade, so the plastic bags need 300 years to break down; and polypropylene chemical structure is not strong, the molecular chain is easy to break, which can be effectively degraded , And in the non-toxic form into the next environmental cycle, a non-woven bags in 90 days can be completely decomposed.
Non-woven fabrics do not need the textile process and made like cloth non-cloth products, also known as non-woven. Because it is only the textile short fiber or filament orientation or random support, the formation of fiber structure, and then use mechanical, thermal or chemical methods can be made to strengthen. Most non-woven bags are made of spunbond nonwovens.
Simply speaking: nonwovens are not woven by a single yarn, knot together, but the fiber directly through the physical method of bonding together, so when you get your clothes in the sticky , It will be found, is not a root of the thread. Nonwovens break through the traditional textile principle, and has a short process flow, production speed, high yield, low cost, wide use, raw materials and more features.
Laminating non-woven bags, products using cast way, compound solid, in the composite process is not viscose, soft to the touch, no plastic feeling, no skin irritation, apply to disposable medical single, bed sheets, Isolation clothing, protective clothing, shoe covers, and other health care products production; this cloth bag is called Fumo non-woven bags.
