What are the uses and advantages and disadvantages of non-woven fabrics
1.spunlace non-woven fabric
The spunlace process is to spray high-pressure fine water jets 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 form a cloth.
3.Pulp air laid non-woven fabric
Airlaid non-woven fabric can also be called dust-free paper and dry-laid 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 non-woven fabric
The wet-laid non-woven fabric is to open the fiber raw materials 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 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 melt-blown non-woven fabrics: polymer feeding---melt extrusion---fiber formation---fiber cooling---netting---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 fabric.
8.Stitched non-woven fabric
Stitch-knitting non-woven fabric is a kind of dry-laid non-woven fabric. The stitch-knitting method uses a 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.
