non woven flap wheel  ( English name : Non Woven) , also known as non-woven, is directed or random fibers constitute a new generation of environmentally friendly materials , with moisture , breathable, flexible, lightweight, non-combustion, easily biodegradable , non-toxic irritating, colorful , inexpensive, recyclable and so on. Such as multi- use polypropylene (pp material ) pellets as raw materials, high temperature melting, spinning , shop classes, hot coiling continuous one-step production. Because of the appearance of a fabric and certain performance called cloth . . Spinning from polypropylene thermally bonded together directly paved network , product strength is better than the average staple products , non-directional strength , longitudinal and transverse strength similar. 8 , in environmental protection , currently used by most non-woven material is polypropylene , polyethylene and plastic raw materials , although the name of the two substances are similar, but in the chemical structure is very different . The chemical molecular structure of polyethylene has a very strong stability , extremely difficult to degrade , so the bag is completed to 300 years to decompose ; the polypropylene chemical structure is not solid, the molecular chains can easily be broken , which can effectively degrade , and in the form of a non-toxic environment into the next cycle , a non-woven shopping bags in 90 days can be completely decomposed . And woven shopping bags can be reused more than 10 times , waste pollution to the environment after only 10% of non-woven plastic fiber is mainly used in the production of polypropylene (PP), polyester (PET). In addition, polyamide (PA), viscose, acrylic , Polyethylene (HDPE), polyvinyl chloride (PVC). According to application requirements , woven into a one-time application-oriented and durable two categories.
