The classification 1. of non-woven spunlace non-woven spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber network
Classification of non-woven fabrics
1. spunlace non-woven fabric
The spunlace process is to spray high-pressure fine water onto one or more layers of fiber mesh, so that the fibers are entangled with each other, so that the fiber mesh can be reinforced and have a certain strength.
2. heat-seal non-woven fabric
Thermal bonding non-woven fabric refers to the addition of fibrous or powdery hot melt bonding reinforcement material in the fiber web, and the fiber web is then heated and 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, dry papermaking non-woven fabric. It uses air-laid technology to loosen the wood pulp fiberboard into a single fiber state, and then uses air-flow method to make the fibers agglomerate on the mesh curtain, and the fiber mesh is reinforced into cloth.
4. wet-laid non-woven fabric
Wet-laid non-woven fabric is placed in the water medium of the fiber raw materials open into a single fiber, at the same time make different fiber raw materials mixed, made of fiber suspension slurry, suspension slurry to the network into the mechanism, the fiber in the wet state into a network and then fixed into cloth.
5. spunbond non-woven fabric
Spunbond non-woven fabric is in the polymer has been extruded, stretched to form a continuous filament, filament laid into a web, and then through its own bonding, thermal bonding, chemical bonding or mechanical reinforcement method, so that the fiber web into a non-woven fabric.
6. meltblown non-woven fabric
The technological process of melt-blown non-woven fabrics: polymer feeding-melt extrusion-fiber formation-fiber cooling-web formation-reinforcement into cloth.
7. needle-punched non-woven fabric
Needle-punched non-woven fabric is a kind of dry-process non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of the needle to reinforce the fluffy fiber web into a cloth.
8. stitched non-woven fabric
The stitch-bonded non-woven fabric is a kind of dry-process non-woven fabric. The stitch-bonding method uses a warp-knitted loop structure to reinforce a fiber web, a yarn layer, a non-woven material (such as a plastic sheet, a plastic thin metal foil, etc.) or a combination thereof to form a non-woven fabric.
Its main uses can be roughly divided:
(1) Medical and sanitary non-woven fabrics: surgical clothing, protective clothing, disinfection disposable non-woven cloth, masks, diapers, civil rags, wipes, wet wipes, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads, and disposable sanitary cloths;
(2) Non-woven fabrics for court decoration: wall covering, table cloth, bed sheets, bedspreads, etc;
(3) Non-woven fabrics for clothing: lining, adhesive lining, wadding, shaped cotton, various synthetic leather backcloth, etc;
(4) Industrial non-woven fabrics; filter materials, insulating materials, cement packaging bags, geotextiles, covering fabrics, etc;
(5) Agricultural non-woven fabrics: crop protection cloth, seedling cloth, irrigation cloth, insulation curtain, etc;
(6) Other non-woven fabrics: space cotton, thermal insulation materials, linoleum, smoke filters, tea bags, etc.
