Hot rolled non-woven fabric is a process in the treatment process

Hot-rolled non-woven fabrics are widely used in our lives. Maybe we are not familiar with it. Today, Shandong Huaqiang Non-woven Fabrics Co., Ltd. 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 high heat (100~150 degrees. The uniform fiber filaments are rolled through the roller to melt and thereby melt. As a net, hot-rolled non-woven fabrics will have rolling spots 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 certain 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 Spinning cloth.


Features of hot rolled non-woven fabrics


1. Lightweight: 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.


2. Soft: 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-repellent and breathable: Polypropylene slices do not absorb water, have zero water content, and have good water-repellent properties. 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: The product is produced with FDA food-grade raw materials, does not contain other chemical components, 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 worm-eaten, and not easy to be corroded.


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 and 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. 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 to the environment after disposal is only 10% of that of plastic bags.


The main use of hot rolled non-woven fabrics


1. Medical materials


2. Filter material


3. Geosynthetics do not use geosynthetics, use geosynthetics


4. Vehicle materials


5. Imitation leather materials for shoes and hats
