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 short textile fibers or filaments to form a web structure, and then uses mechanical, thermal 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.
1 Features of non-woven fabric
The non-woven fabric has no warp and weft threads, it is very convenient for cutting and sewing, and it is light and easy to shape. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide use, and multiple sources of raw materials.
Polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, which is only three-fifths of cotton. It is fluffy and feels good.
Composed of fine fibers (2-3D), light spot-like hot melt bonding molding. The finished product is moderately soft and comfortable.
Water repellent and breathable
Polypropylene slices do not absorb water, have zero moisture content, and have good water repellency. It is composed of 100% fibers and has a porous property, good air permeability, and easy to keep the cloth dry and easy to wash.
The product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, has no peculiar smell, and does not irritate the skin.
Polypropylene is a chemically blunt substance, does not eat insects, and can isolate the bacteria and insects in the liquid.
The product is water-repellent, not moldy, and can isolate the corrosion of bacteria and insects in the liquid, and is not moldy.
Good physical properties
It is made of polypropylene spun yarn directly spread into a net and thermally bonded. The strength of the product is better than that of ordinary staple fiber products.
In terms of environmental protection, the raw material of most of the 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 degrade, 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 to the environment after disposal is only 10% of that of plastic bags.More about:Non-woven scouring pad
