    Non-woven fabric, also called non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties.

    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. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. 

    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 kind of 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 yarns, 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 spun-bond fabric

    Spun-bond fabric and non-woven fabric are subordinate. There are many production processes for the manufacture of non-woven fabrics, among which spun-bond method is one of the non-woven fabric production processes.

Spun-bond non-woven fabric

(Including spun-bond method, melt-blown method, hot rolling method, spun-lace method, most of the non-woven fabrics on the market are produced by spun-bond 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 spun-bond fabric usually refers to polyester spun-bond and polypropylene spun-bond; 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 hydrogen-tangling, needle punching, or hot rolling reinforcement, and finally finishing the resulting non-woven fabric. A new type of fiber product has 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 has cotton feel. Compared with cotton fabrics, non-woven bags are easier to shape and cheaper to manufacture.
