What are the classifications of non-woven fabrics
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, so that the fibers are entangled 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 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-laid 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, the different fiber raw materials are mixed to form a fiber suspension slurry. The suspension slurry is transported to the 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 through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. The web becomes a non-woven fabric.
6. Meltblown 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 puncture 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 the warp-knitted loop structure to couple fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or a combination of them. The body is reinforced to make a non-woven fabric.
