Types Of Non-woven Fabrics

19-03-2024

According to different production processes, non-woven fabrics can be divided into:

1. Spunlace non-woven fabric: It sprays high-pressure fine water 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-bonding non-woven fabric: refers to adding fibrous or powdery hot-melt adhesive reinforcement material 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 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 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. Melt-blown non-woven fabric: its technological process: polymer feeding --- 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. The needle-punched non-woven fabric uses the piercing effect of a needle to reinforce the fluffy web into a cloth.

8. Stitched non-woven fabric: It is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to align fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or Their combination is reinforced to make a non-woven fabric.
