What are the advantages of hot-rolled non-woven fabrics?
The advantages and main uses of hot-rolled non-woven fabrics . The hot-rolled non-woven fabrics (calendar bonded) are made of high-quality ES composite fibers, which are mechanically carded into a web, and then a pair of hot rolls are used to heat the web, which is composed of two roll jaws. The hot-rolled bonding zone heats and presses the fed fiber web, and the thickness and density of the fiber web change, which changes the thermal conductivity, which causes some fibers in the web to melt, flow and diffuse, thereby resulting in bonding, which is reinforced after cooling. The fiber web is hot-rolled non-woven fabric. Six advantages 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 moderat...
