Introduction to various production processes of non-woven fabrics

Non-woven fabric is a general term for all types of non-woven fabrics, which are subdivided into multiple types according to different processing techniques. Next, I will talk about the various processing techniques of non-woven fabrics.　　 Spunlace non-woven fabric: High-pressure fine water jet is sprayed onto one or more layers of fiber webs to entangle the fibers with each other, so that the web can be reinforced and have a certain strength.　　 heat-bonding non-woven fabric: adding fibrous or powdery hot-melt adhesive reinforcement material to the fiber web, and then the fiber web is heated, melted and cooled to reinforce the fabric.　　 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. 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 form a fiber suspension slurry. The suspension slurry is transported to the web forming mechanism, and the fibers are formed into a web in a wet state. Reinforce into cloth. 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 bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make The web becomes a non-woven fabric.　　 Melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling---web formation---reinforcement into cloth.　　 Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric uses the piercing effect of a needle to reinforce the fluffy web into a cloth. Stitched non-woven fabric: It is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to connect fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their The assembly is reinforced to make a non-woven fabric.　　 Hydrophilic non-woven fabric: Mainly used in the production of medical and sanitary materials to achieve better hand feeling and not scratch the skin. For example, sanitary napkins and sanitary pads utilize the hydrophilic function of hydrophilic non-woven fabrics.　　 Nonwovens Co., Ltd. produces all kinds of nonwovens products.
