The Principle Of Non-woven Bags

- Oct 31, 2017-

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.
