Classification Of Non-woven Fabrics
With the development of the non-woven fabric industry, more and more people use Non-woven Shopping Bag. As a result, the types of non-woven fabrics have become richer. The following will introduce the types of non-woven fabrics.
1. Spunlace non-woven fabrics The spunlace process is to spray high-pressure fine water flow 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-bonded non-woven fabrics Heat-bonded non-woven fabrics refer to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is then heated, melted, cooled and reinforced into cloth.
3. Pulp air-laid non-woven fabrics Air-laid non-woven fabrics can also be called dust-free paper and dry papermaking non-woven fabrics. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air flow method to agglomerate the fibers on the mesh curtain, and the fiber web is reinforced into cloth.
4. Wet-laid nonwovens Wet-laid nonwovens are made by opening fiber raw materials placed in a water medium into single fibers, and mixing different fiber raw materials to form a fiber suspension slurry. The suspension slurry is transported to a web-forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into a cloth.
5. Spunbond nonwovens Spunbond nonwovens are made by laying the filaments into a web after the polymer has been extruded and stretched to form continuous filaments. The web is then bonded, thermally bonded, chemically bonded or mechanically reinforced to make the web into a nonwoven fabric.
6. Meltblown nonwovens The process of meltblown nonwovens: polymer feeding---melt extrusion---fiber formation---fiber cooling---web formation---reinforcement into cloth.
7. Needle-punched nonwovens Needle-punched nonwovens are a type of dry-laid nonwovens. Needle-punched nonwovens use the puncture of needles to reinforce the fluffy web into cloth.
8. Stitchbonded non-woven fabric Stitchbonded non-woven fabric is a kind of dry-laid non-woven fabric. The stitchbonding method uses a warp knitting coil structure to reinforce the fiber web, yarn layer, non-textile material (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make non-woven fabric.
