Features and main uses of hot rolled non-woven fabrics

Hot-rolled non-woven fabrics are widely used in our lives. Maybe we are not familiar enough with it. Today we will introduce the characteristics of hot-rolled non-woven fabrics. Hot rolling is the last web-forming technology in the production process of non-woven fabrics. It is a process for fabrics after cooling and laying. Hot rolling has a high degree of heat (100-150 degrees rolling through the uniform fiber filaments to melt and become Net, so the hot-rolled non-woven fabric will have rolling points on the fabric surface, which are similar to pinholes, but do not penetrate. The specific size depends on the size and density of the steel thorns on the rolling wheel. Hot-rolled non-woven fabrics are not specific A kind of cloth, but a general term for a kind of non-woven fabrics made through similar processes. Generally speaking, the hot rolling process is spunbonded non-woven fabric, polypropylene non-woven fabric, PP non-woven fabric, polyester non-woven fabric Fabric. Features of hot-rolled non-woven fabric 1. Light weight: 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 has a good hand feeling. 　　 2. Softness: composed of fine fibers (2-3D) Light spot-like hot-melt bonding molding. The finished product is moderately soft and comfortable. 　　 3. Water repellent and breathable: Polypropylene slices do not absorb water, have zero moisture content, and have good water repellency. The finished product is composed of 100% fiber Porous, good air permeability, easy to keep the cloth dry and easy to wash.　　4, non-toxic, non-irritating: the product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, non-toxic, no odor, Does not irritate the skin. 　　5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, not moth-eaten, and not easy to be corroded. 　6. Antibacterial property: The product is water-repellent, does not mold, and can isolate bacteria and insects in the liquid Good physical properties: It is made of polypropylene spun yarn and directly spread 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. Environmental protection: The main material of the hot-rolled non-woven fabric is polypropylene, the chemical structure is not strong, the molecular chain can be easily broken, which can be effectively degraded, and the non-woven shopping bag can be reused more than 10 times. The pollution degree of plastic bags is only 10% of that of plastic bags. 　　 The main uses of hot-rolled non-woven fabrics 1, medical and health materials 2, filter materials 3, geosynthetics without using geosynthetics, using geosynthetics, 4, automotive materials, 5, shoes Cap imitation leather material Previous: Characteristics and main applications of spunlace non-woven fabrics
