Classification of non-woven fabrics
1. Wet-laid non-woven fabrics: The non-woven bag manufacturers introduce this kind of non-woven fabrics. The fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to make fiber suspension pulp. The pulp is transported to the web-forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into a cloth; acupuncture non-woven fabric: it is a kind of dry non-woven fabric. The fiber mesh is reinforced into cloth.
2. Thermal bonding non-woven fabrics: refers to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is then heated, melted and cooled to reinforce into cloth; stitched non-woven fabrics: the use of warp knitted coil structure Webs, layers of yarns, nonwoven materials, or combinations thereof are consolidated to make nonwovens.
3. Spunbond non-woven fabric: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. , so that the fiber web becomes a non-woven fabric; spunlace non-woven fabric: the non-woven bag manufacturer sprays high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber web can be reinforced and Have a certain strength.
