Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic, non-irritating, and rich in colors. , Low price, recyclable and other characteristics. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by a continuous one-step method of high temperature melting, spinning, laying, and hot-pressing. It is called non-woven fabric because of its appearance and certain properties.
1. Lightweight: Polypropylene resin is used as the main raw material for production. The specific gravity is only 0.9, only three-fifths of cotton. It is fluffy and feels good.
2. Soft: It is composed of fine fibers (2-3D) and is formed by lightly hot-melt bonding. The finished product is moderately soft and comfortable.
3. Water-repellent and breathable: Polypropylene slices do not absorb water, have zero water content, and have good water-repellent properties. They are made of 100% fiber and are porous and have 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: 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 directly laid into a net and thermally bonded. The product strength is better than ordinary staple fiber products, the strength is non-directional, and the vertical and horizontal strengths are similar.
8. In terms of environmental protection, most of the non-woven fabrics currently in use are made of polypropylene, and 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 the plastic bag.
