Non woven fabric, also known as non-knitting fabric or Nonwoven Cloth, is composed of directional or random fibers. It is called cloth because of its appearance and some properties.
The non-woven fabric has advantages of moisture-proof, breathable, flexible, light, non-combustion supporting, easy to decompose, non-toxic and non-irritant, rich in color, low in price and recyclable. For example, polypropylene (PP material) particles are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, wire spraying, sizing and hot rolling.
Features: non-woven fabric has no warp and weft thread, so it is very convenient to cut and sew, and it is light and easy to shape, so it is popular with handcraftsmen.
Because it is a kind of fabric which does not need spinning and weaving, 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 non-woven and spunbond: spunbond and non-woven are subordinate. There are many production processes in the manufacture of non-woven fabrics, among which spunbond is one of them.
Spunbond nonwovens: (including spunbond method, melt blown method, hot rolling method and spunlace method. Most of the nonwovens on the market are produced by spunbond method).
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 cotton sensation. Compared with cotton fabric, the bag of non-woven fabric is easy to form and cheap.
