Non-woven, also known as non-woven, is made of directional or random fiber, is a new generation of environmentally friendly materials, with moisture, breathable, flexible, light, non-combustion, easy to break down, non-toxic non-irritating, rich colors, price Low, recyclable and so on. Such as the use of polypropylene (pp material) pellets as raw materials, high temperature melting, spinneret, paving, hot coiling continuous production from one step. Due to the appearance of cloth and some performance and called the cloth.
The From polypropylene spinning directly paved into a hot bond, the strength of the product is better than the general staple fiber products, the strength of non-directional, vertical and horizontal intensity similar. 8, in environmental protection, the current use of most non-woven raw materials are polypropylene, and plastic bags of raw materials are 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 cycle of the environment, a Non Woven Shopping Bag in 90 days can be completely decomposed. And Non Woven Shopping Bag can be reused more than 10 times, the pollution of the environment after the pollution is only 10% of plastic bags
Nonwovens production fiber is mainly polypropylene (PP), polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic, sponge (HDPE), polyvinyl chloride (PVC). According to the application requirements, non-woven fabrics are divided into one-time application and durable two categories.
At present, man-made fibers still dominate the production of non-woven fabrics, and before 2007, this situation will not have a big change. 63% of the fibers used in the production of nonwovens worldwide are polypropylene, 23% polyester, 8% viscose, 2% acrylic fiber, 1.5% polyamide, and the remaining 3% fiber.
