, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color Inexpensive and recyclable. For example, polypropylene (pp material) pellets are used as raw materials, and are produced by a continuous one-step method of high temperature melting, spinning, laying, and hot pressing and coiling. It is called cloth because of its appearance and certain properties.
The non-woven fabric has no warp and weft threads, so it is very convenient to cut and sew, and it is light and easy to shape.
Because it is a fabric that does not require spinning or weaving, it just orients or randomly arranges textile staple fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical methods to reinforce it.
It is not interwoven and braided by yarns one by one, but the fibers are directly bonded together by physical methods, so when you get the sticky scale in your clothes, you will find that, You can't get a single thread out. Nonwovens break through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide application, and many sources of raw materials.
According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different components will have completely different styles of non-woven fabrics.
Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through air flow or machinery, and then is spunlaced, needle punched, or hot rolled for reinforcement. The non-woven fabric formed by finishing. A new type of fiber product with a soft, breathable and flat structure, the advantage is that it does not produce lint, it is strong, durable, and silky soft, and it is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven Cloth bags are easy to form, and non-woven bags are cheap.
