Nonwovens fabric, is directed or random fibers constitute a new generation of environmentally friendly materials , with moisture , breathable , flexible, lightweight , non-combustion , easily biodegradable, non-toxic non -irritating, colorful , inexpensive, can be recycling 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 from production. Has the appearance and performance by some cloth called cloth .
. Spinning polypropylene thermally bonded together directly paved network , product strength is better than the average staple products , the strength of non-directional , vertical and horizontal strength similar. 8 , the environment, the majority of non-woven materials currently used is polypropylene, polyethylene and plastic raw materials , although the names of the two substances are similar, but are very different in chemical structure . The molecular structure of polyethylene having a very strong chemical stability , degradation is extremely difficult , so the decomposition of the plastic bag 300 years to complete ; the chemical structure of polypropylene is not solid, the molecular chains can easily be broken , which can effectively degrade , and the next step in the form of a non-toxic environment in circulation , a non-woven shopping bags in 90 days can be completely decomposed. And woven shopping bags can be reused more than 10 times the pollution of the environment after the waste is also only 10% of plastic bags
Non-woven fiber production is mainly 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.
Currently, non-woven rayon still dominate production , and by 2007 , this situation will not change much . Fiber used worldwide in the production of non-woven polypropylene , 63% , 23% polyester , 8% viscose, 2% acrylic fibers , polyamide 1.5% , and the remaining 3% for other fibers.
