What you should know about non-woven fabrics

Non-woven fabric (non-woven fabric) is a kind of fabric that does not need to be spun and woven. It just aligns or randomly arranges textile short fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical Reinforced by other methods. To put it simply: 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 out the thread ends. The characteristics of non-woven fabrics Non-woven fabrics have no warp and weft threads, which are very convenient for cutting and sewing, and are light in weight and easy to shape. 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. Advantages 1. Light weight, using polypropylene resin as the main raw material, with a specific gravity of only 0.9, which is only three-fifths of cotton. It is fluffy and feels good. 2 Soft, composed of fine fibers (2-3D), light spot-like hot-melt bonding molding. The finished product is moderately soft and comfortable. 3 Water-repellent, breathable polypropylene slices do not absorb water, have zero moisture content, and have good water repellency. It is composed of 100% fiber and has good air permeability. It is easy to keep the cloth dry and easy to wash. 4 Non-toxic, non-irritating products are produced with FDA food-grade raw materials, without other chemical ingredients, stable performance, non-toxic, no peculiar smell, and no skin irritation. 5 Chemical resistance Polypropylene is a chemically blunt substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid. 6 Antibacterial products are water-repellent, not moldy, and can isolate the erosion of bacteria and insects in the liquid, and are not moldy. 7 Good physical properties: It is made of polypropylene spun yarn directly laid into a net and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. 8 Environmental protection In terms of environmental protection, the raw material of most non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to decompose, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the pollution degree to the environment after being discarded is only 10% of that of the plastic bag.
