Non-woven fabric (non-woven fabric) is a kind of fabric that does not need to be spun and weaves. It just aligns or randomly arranges textile short fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical Reinforced by other methods.
To put it simply: it is not interwoven and knitted together one by one yarn, but the fibers are directly bonded together by physical methods, so when you get the sticky scale in your clothes , You will find that it is impossible to draw out the thread ends.
Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low price, and recyclable.
Non-woven fabrics are also divided into new and old technologies or a broad and narrow sense. The old technology makes synthetic flannel that looks like work. The new technology has resulted in common environmentally friendly shopping bags, N95 masks, and many curtain rag products in the ten-yuan store. The texture often has even and neat impression points. In a broad sense, non-woven fabrics include all cloth-like objects that are not woven with threads, even paper; in a narrow sense, non-woven fabrics refer to finished products with neatly imprinted parts.
Non-woven textile bags can be made of any fiber. If there is a textile recycling plant nearby, these recycled fibers can be transported at low cost for further processing.
The fiber can be broken cloth, man-made fiber or synthetic fiber (glue, resin, etc.). The fiber raw material of non-woven fabric often contains polypropylene (Polypropylene), referred to as PP, which is continuously melted by high temperature, spinning, laying and hot pressing. It is produced by one-step method, or polyethylene, or PE for short.
Non-woven fabrics are not woven by warp and weft like woven fabrics. The production of non-woven fabrics varies with different methods. For example, the needle rolling method uses thousands of needles to continuously hook cotton up and down to make the cotton Tangled with each other, each tangled will make the cotton body more and more solid.
