Advantages and disadvantages of non-woven fabrics

Non-woven fabrics are widely used in life, and you can see non-woven fabrics everywhere. So what are the advantages and disadvantages of non-woven fabrics? The advantages of non-woven fabrics 1. Lightweight: use polypropylene resin as the main production material , The specific gravity is only 0.9, only three-fifths of cotton, it is fluffy and feels good.　　2. Softness: It is composed of fine fibers (2-3D) and is formed by light-point hot-melt bonding. The finished product is moderately soft and comfortable.　　3. Water repellency and breathability: Polypropylene slices do not absorb water, have zero water content, and have good water repellency. It is composed of 100% fibers and has good air permeability. It is easy to keep the cloth dry and easy to wash.　　4. Non-toxic and non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical ingredients, has stable performance, is non-toxic, non-odor, and does not irritate the skin.　　 5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, not moth-eaten, and can isolate the corrosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and the strength of the finished product will not be affected by erosion.　　 6. Antibacterial property. The product is water-repellent, not moldy, and can isolate the erosion of bacteria and insects in the liquid, and is not moldy.　　7. Good physical properties. It is made of polypropylene spun yarn and directly spread into a net and thermally bonded. The strength of the product is better than that of ordinary staple fiber products.　　 8. 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 degrade, so it takes 300 years for the plastic bag 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 being discarded is only 10% of that of plastic bags. Disadvantages of non-woven fabrics: 　　 1) Compared with woven fabrics, the strength and durability are poor.　　2) Cannot be washed like other fabrics.　　3) The fibers are arranged in a certain direction, so it is easy to split from the right angle direction, etc. Therefore, the improvement of the production method mainly focuses on the improvement of preventing splitting.
