There is no warp and weft in non-woven fabric, so it is very convenient to cut and sew, and it is light and easy to shape, so it is very popular with handcraftsmen.
Because it is a kind of fabric which does not need spinning and weaving, it is just a kind of fabric which is made of short textile fibers or filaments arranged randomly or directionally to form a fiber net structure, and then reinforced by mechanical, thermal adhesive or chemical methods.
It is not interweaved and weaved by one yarn, but the fibers are directly bonded together by physical methods, so when you get the scale in your clothes, you will find that there is no thread out. Nonwovens break through the traditional textile principle, and have the characteristics of short technological process, fast production rate, high output, low cost, wide use and many sources of raw materials.
The relationship between nonwoven and spunbond
Spunbond and nonwovens are subordinate. There are many production processes for the manufacture of non-woven fabrics, among which spunbond is one of them (including spunbond, melt blown, hot rolled and Spunlaced processes, most of which are produced by spunbond at present)
According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different compositions will have different styles of non-woven fabrics. While spunbond usually refers to polyester spunbond and polypropylene spunbond, and the style of these two kinds of fabrics is very similar, which can be distinguished by high temperature test.
Non woven fabric is a kind of non-woven fabric. It is a kind of non-woven fabric that directly uses polymer chips, short fibers or filaments to form a net by air flow or machinery, and then it is reinforced by pricking, needling, or hot rolling, and finally it is finished. A new type of fiber product with soft, breathable and plane structure has the advantages of no fiber chips, strong, durable and silky softness. It is also a kind of reinforced material, and has the feeling of cotton. Compared with cotton fabric, the bag of non-woven fabric is easy to form and cheap.
