Eight categories of non-woven fabrics

Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of directional or random fibers. It is called cloth because of its appearance and certain properties.

Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low price, and recyclable. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing.

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 the fiber web is heated, melted and cooled to be consolidated into a cloth.

3. Pulp air-laid 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 make 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 web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make The web becomes a non-woven fabric.

6.melt blown non-woven fabric

The process of meltblown non-woven fabric: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- forming a net --- strengthening into cloth.

7.needle punched non-woven fabric

Needle-punched non-woven fabrics are a kind of dry-laid non-woven fabrics. Needle-punched non-woven fabrics use the piercing effect of needles to reinforce the fluffy web into a fabric.

8. Stitched non-woven fabric

Stitched non-woven fabric 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 The body is reinforced to make a non-woven fabric.
