The non-woven fabric has no warp and weft threads, it is very convenient to cut and sew, and it is light in weight and easy to shape.
Because it is a fabric that does not need to be spun and weaves, it just oriented or randomly arrange the textile short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.
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 a single thread. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production rate, high output, low cost, wide use, and multiple sources of raw materials.
The relationship between non-woven fabric and spunbond fabric
Spunbond fabric and non-woven fabric are subordinate. There are many production processes in the manufacture of non-woven fabrics, among which spunbond is one of the non-woven production processes (including spunbond, meltblown, hot rolling, spunlace, and most of them are on the market. Non-woven fabric produced by spunbond method)
According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different compositions will have completely different styles of non-woven fabrics. The spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; and the styles of these two fabrics are very similar, which can be distinguished by high temperature testing.
Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or mechanical netting, and then undergo hydroentangling, needle punching, or hot rolling reinforcement, and finally finishing The resulting non-woven fabric. A new type of fiber product with soft, breathable and flat structure. The advantage is that it does not produce fiber debris, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it has a cotton feel. Compared with cotton, non-woven The cloth bag is easy to form and cheap to manufacture.
