What are the classifications of non-woven fabrics

1. The spunlace non-woven fabric spunlace process is to spray a high-pressure fine water stream onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. 2. Thermal bonding non-woven fabric Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement material to the fiber web, and the fiber web is heated, melted and cooled to be consolidated into a fabric. 3. Pulp air-laid non-woven fabric Air-laid non-woven fabric can also be called dust-free paper and dry paper-making non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the web curtain, and then reinforce the fiber web into a cloth. 4. Wet-laid non-woven fabrics Wet-laid non-woven fabrics are used to open fiber raw materials placed in an aqueous medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to the web forming mechanism, and the fiber In the wet state, it is formed into a net and then reinforced into a cloth. 5. Spunbond non-woven fabric Spunbond non-woven fabric is formed after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a net, and the aluminized non-woven fabric web is then bonded and heated by itself. Bonding, chemical bonding or mechanical reinforcement methods make the web into a non-woven fabric. 6. Melt-blown non-woven fabric The process of melt-blown non-woven fabric: polymer feeding-melt extrusion-fiber formation-fiber cooling-net formation-reinforcement into cloth. 7. Needle-punched non-woven fabrics Needle-punched non-woven fabrics are a kind of dry-laid non-woven fabrics. Needle-punched non-woven fabrics use the piercing effect of needles to reinforce the fluffy web into a cloth. 8. Stitch-woven non-woven fabrics are a kind of dry-laid non-woven fabrics. The stitch-bonding method uses warp-knitted loop structure to align fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal, etc.). Foil, etc.) or their combination is reinforced to make a non-woven fabric.
