Non woven fabric is a new generation of environmental protection materials, which is composed of directional or random fibers. It is moisture-proof, breathable, flexible, light weight, non combustion supporting, easy to decompose, non-toxic and non irritating, rich in color, low price and recyclable. For example, polypropylene (PP) granules are usually used as raw materials, which are produced by continuous one-step process of high-temperature melting, wire spraying, thread laying and hot pressing coiling. It is called cloth because of its appearance and some properties.
Non woven fabric is a new type of fiber product with soft, breathable and plane structure. It has the advantages of no fiber chips, strong, durable and silky soft. It is also a kind of reinforcing material, and has the feeling of cotton. Compared with cotton fabric, the bag of non-woven fabric is easy to form and cheap to make. The disadvantage of non-woven fabric is its poor strength and durability, and it can not be cleaned like other fabrics. Because the fibers are arranged in a certain direction, it is easy to split from the right angle direction.
It is a new generation of environmental protection materials, with water repellent, breathable, flexible, non combustion, non-toxic, non irritant, colorful and so on. When burning, it is non-toxic, tasteless and free of any residual substances, so it does not pollute the environment, so environmental protection comes from it. The chemical structure of polypropylene is not firm, the molecular chain can be easily broken, so it can be effectively degraded, and enter the next environmental cycle in the non-toxic form.
