Classification Of Non-woven Fabrics

According to application requirements: non-woven fabrics are divided into two categories: disposable application type and durable type.

According to the production process, it is divided into:

1. Spunlace non-woven fabric: The spunlace process 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. Thermally bonded non-woven fabric: Thermally bonded non-woven fabric refers to the addition of fibrous or powdery hot-melt bonding reinforcement materials into the fiber web, and the fiber web is heated, melted and cooled to reinforce into a cloth.

3. 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.

4. Wet-laid non-woven fabric: 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 make a fiber suspension slurry, which is transported to the web forming mechanism. The fibers are formed into a net in a wet state and then reinforced into a cloth.

5. Spunbond non-woven fabric: Spunbond non-woven fabric is formed after the polymer has been extruded and stretched to form continuous filaments. Bonding or mechanical reinforcement method, the fiber web becomes a non-woven fabric.

6. Melt-blown 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 puncture effect of needles to reinforce the fluffy web into a cloth.

8. Stitched non-woven fabric: Stitched non-woven fabric is a kind of dry-laid non-woven fabric. The stitching method uses warp-knitted loop structure to connect fiber webs, yarn layers, and non-woven materials (such as plastic sheets, thin plastic sheets). Metal foil, etc.) or their combination is reinforced to make a non-woven fabric.

9. 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 use the hydrophilic function of hydrophilic non-woven fabrics.
