Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, rich color, low price and recyclable reuse. For example, polypropylene (pp material) granule is used as raw material, which is produced by continuous one-step process of high temperature melting, spinning spraying, laying and hot pressing.
Non-woven fabric has no warp and weft, and is easy to cut and sew,they are very popular among handcraft lovers.
Because it is a kind of don’t need to be formed by spinning weaving fabric, just short textile fiber or filament for directional or random arrangement, form a fiber network structure, and then by adopting the method of mechanical, hot glue or chemical reinforcement.
According to the composition, there are polyester, polypropylene, polyamide, spandex, acrylic, etc. Different ingredients can have distinct non-woven styles. And spin viscose cloth, usually refers to polyester viscose, polypropylene viscose; The two fabrics are very similar in style and can be distinguished by high temperature testing.
Non-woven fabric is a kind of nonwoven fabric, it is directly using polymer slice, short fibers or filament fiber by air flow or machine into the net, and then through the water thorn, acupuncture, or hot rolling reinforcing, finally after finishing of woven fabrics. With soft, breathable and plane structure of new type fiber products, advantage is that do not produce fiber crumbs, strong, durable, soft as silk, is also a kind of reinforced material, but also the feeling of cotton, compared with cotton, non-woven bag, easy forming and cheap.
