Generally, we can divide non-woven fabrics into the following eight categories according to their causes:
(1) Spunlace non-woven fabric: Spray high-pressure fine water flow onto one or more layers of fiber webs to entangle the fibers with each other, thereby strengthening the fiber webs.
(2) Heat-bonded non-woven fabric: refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, so that the fiber web is heated, melted and then cooled, and reinforced into a cloth.
(3) Pulp air-laid non-woven fabric: also known as dust-free paper and dry-laid non-woven fabric. It uses air-laid technology to turn wood pulp fibers into single fibers, and uses airflow to agglomerate the fibers on the web-forming curtain and then reinforce them into cloth.
(4) Wet-laid non-woven fabric: The fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed to make a fiber suspension slurry, which is sent to the web forming mechanism, and the web is formed and reinforced in a wet state. cloth.
(5) Spun-bonded non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, it is laid into a web, and the fiber web is bonded or mechanically reinforced to become a non-woven fabric.
(6) Melt-blown non-woven fabric: The production steps are polymer input-melt extrusion-fiber formation-fiber cooling-netting-reinforcement into cloth.
(7) Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric, which uses the puncture effect of a needle to reinforce the fluffy fiber web into a cloth.
(8) Stitch-bonded non-woven fabric: It is a kind of dry-laid non-woven fabric, which is made by reinforcing web, yarn layer, non-woven materials (such as plastic sheets, etc.) or their combination by warp-knitted coil structure non-woven fabric.
