How to classify non-woven fabric production processes

1. Spunlace non-woven fabric

  The 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. Heat-sealing non-woven fabric

  Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement material to the fiber web, and then the fiber web is heated, melted and cooled to reinforce into a cloth.

3. Airlaid non-woven fabric

   Airlaid non-woven fabrics can also be called dust-free paper and dry-laid non-woven fabrics. 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 non-woven fabric

The wet-laid non-woven fabric is to open the fiber raw materials placed in the water medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to a web forming mechanism, and the fibers are formed into a web in a wet state. Reinforce into cloth.

5. Spunbond non-woven fabric

Spunbond non-woven fabrics are formed after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a net, and the fiber net is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make The web becomes a non-woven fabric.

6. Meltblown 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 fabric

   Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the piercing effect of needles to reinforce the fluffy web into a cloth.

8. Stitched non-woven fabric

Stitched non-woven fabrics are a kind of dry-laid non-woven fabrics. The stitching method uses a warp-knitted loop structure to bond fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combination The body is reinforced to make a non-woven fabric.
