Non-woven fabric (non-woven fabric), also known as non-woven fabric, is a fabric produced by needle-rolling mechanical or carding machinery for processing various fiber raw materials and forming or bonding them by high pressure. Non-woven fabrics are also divided into new and old technologies or broad sense. The old technology is made into a synthetic flannel that works like a labor. The new technology is responsible for the common environmentally friendly shopping bags, N95 masks, and many curtain rag products in the ten yuan store. There is often an average embossing point on the texture. The generalized nonwoven fabric contains all fabrics that are not woven with threads, or even paper; narrowly defined nonwoven fabrics refer to finished products that are neatly left to be embossed. Non-woven textile bags can be made from any fiber. If there is a textile recycling factory nearby, these recycled fibers can be transported at low cost for further processing. The fiber may be woven, rayon or synthetic fiber (glue, resin, etc.), and the non-woven fiber material usually contains polypropylene (PP). Non-woven fabrics are not woven from warp and weft. The manufacture of non-woven fabrics varies with the construction method. For example, the needle-rolling method is to make cotton through thousands of needle-punching needles. Tangle with each other, each tangled will make the cotton body more and more solid.
