Types and characteristics of non-woven fabrics

Non-woven fabrics can be divided into the following types according to different production processes:

1. Stitched non-woven fabric

The nonwoven fabric is made by reinforcing a web, a yarn layer, a nonwoven material (e. g., a plastic sheet, a plastic thin metal foil, etc.) or a combination thereof with a warp-knitted loop structure. It is a kind of dry non-woven fabric

2. Needle punched non-woven fabric

The fluffy fiber web is reinforced into a cloth, which is a kind of dry non-woven fabric, and the needle-punched non-woven fabric uses the puncture effect of the needle.

3. Meltblown non-woven fabric

The process: polymer feed-melt extrusion-fiber formation-fiber cooling-mesh-reinforcement into cloth.

4. Spunbond non-woven fabric

The web is then subjected to self-bonding, thermal bonding, chemical bonding or mechanical strengthening methods to make the web into a non-woven fabric. After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web.

5. Wet-laid non-woven fabric

The fiber suspension slurry is made, and the suspension slurry is transported to the mesh forming mechanism, and the fibers are reeled and solidified into cloth in the wet state. It is to open the fiber raw material in the water medium into single fiber, and mix the different fiber raw materials at the same time.

6. Pulp air-laid non-woven fabric

Then the fiber is agglomerated on the mesh curtain by air flow method, and the fiber web is solidified into cloth. It is the wood pulp fiber board is opened into a single fiber state by air flow forming technology. It can also be called dust-free paper and dry papermaking non-woven fabric.

7. Heat-bonding non-woven fabric

The fiber web is then heated, melted, cooled and reinforced into a cloth, which refers to the addition of fibrous or powdery hot-melt adhesive reinforcement material into the fiber web.

8. Spunlace non-woven fabric

The fibers are entangled with each other so that the web is reinforced with a certain strength. It is a high-pressure fine water jet onto one or more layers of fiber mesh.

The difference between pp non-woven fabric and spunlace non-woven fabric

It is reinforced by mechanical, thermal bonding or chemical methods, because it is a fabric formed without spinning and weaving, but the textile staple fibers or filaments are oriented or randomly braced to form a fiber net structure. Now explain in detail the PP non-woven fabric: the exact name of the non-woven fabric should be non-woven, or non-woven. These two kinds of non-woven fabrics are mainly different from the process, and the specific cloth is not essentially different. The difference between pp non-woven fabric and spunlace non-woven fabric, PP refers to the raw material of non-woven fabric is PP, spunlace non-woven fabric is said to be the production process
