The non-woven fabric has no warp and weft threads, it is convenient to cut and sew, and it is light 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 made of yarns that are interwoven and knitted together, but the fibers are directly bonded together by physical methods. Therefore, when you get the sticky scale in your clothes, you will find that it is Can’t draw out the end of the 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 fabrics and spunbond fabrics
Spunbond fabric and non-woven fabric are subordinate. There are many production processes for the manufacture of non-woven fabrics, among which spunbond method is one of the non-woven fabric production processes
Spunbond non-woven fabrics (including spunbond, meltblown, hot-rolled, water-saturated, most of the non-woven fabrics on the market are produced by spunbond)
non-woven fabrics are polyester, polypropylene, nylon, spandex, acrylic, etc. according to the composition; different compositions 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 similar, it can be distinguished by high temperature test.
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 then finishing The resulting non-woven fabric. A new type of fiber product with soft, air-permeable and flat structure. The advantage is that it does not produce fiber debris, is strong, and silky soft. It is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven fabrics The bag is easy to form and cheap to make.
