Non-woven fabrics, understand the production process of non-woven fabrics

The environmental protection of non-woven fabrics has become a symbol of environmental protection in the current society. The characteristics of non-woven fabrics are conducive to decomposition and have a great impact on the environmental protection of daily waste. The name of non-woven fabrics means that the production process is different. Everyone introduces the production process of several non-woven fabrics. 1. Spunlace non-woven fabric: It sprays high-pressure fine water flow 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. Heat-bonded non-woven fabric: refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and the fiber web is heated, melted and cooled to reinforce into a cloth. 3. Pulp air-laid non-woven fabric: also known as 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 the air-flow method to agglomerate the fibers on the web curtain, and then strengthen the fiber web into a 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 at the same time to form a fiber suspension slurry, which is transported to the web forming mechanism, and the fibers are in a wet state. Form a net and then reinforce into a cloth. 5. 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 bonded by itself, thermally bonded, chemically bonded or mechanically reinforced Method to make the web into a non-woven fabric. 6. Meltblown non-woven fabric: The process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- net formation --- reinforcement into cloth. 7. 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. 8. Stitch-knitted non-woven fabric: It is a kind of dry-laid non-woven fabric. The stitch-knitting method uses the warp-knitted loop structure to align the fiber web, yarn layer and non-woven materials.
