Non-woven fabric scientific name: Nonwovens (Nonwovens), also known as non-woven fabric, non-woven fabric, non-woven fabric, non-woven fabric. Non-woven technology is a material processing technology that originated from textiles but surpasses textiles.
The classification of non-woven fabrics is as follows:
1. Classification according to production process
1. Spunlace non-woven fabric:
The high-pressure fine water jet is sprayed onto one or more layers of the fiber web to make the fibers entangled with each other, so that the fiber web can be reinforced and possess a certain strength.
2. Heat-sealing non-woven fabric:
Refers to adding fibrous or powdery hot-melt adhesive reinforcement materials 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:
It can also be called dust-free paper and dry paper-making 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 fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time 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 and then consolidated into a cloth.
5. Spunbond non-woven fabric:
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 become non-woven cloth.
6. Meltblown non-woven fabric:
The process: polymer feeding→melt extrusion→fiber formation→fiber cooling→netting→reinforcement into cloth.
7. Needle punched non-woven fabric:
A type of dry-laid non-woven fabrics, needle-punched non-woven fabrics use the piercing effect of a needle to reinforce the fluffy web into a cloth.
8. Stitched non-woven fabric:
A kind of dry-laid non-woven fabrics. The stitch-knitting method uses a warp-knitted loop structure to reinforce fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combinations to make Into a non-woven fabric.
2. Classification according to purpose
1. Medical and sanitary non-woven fabrics:
Surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wiping cloths, wet face towels, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths, etc.;
2. Non-woven fabric for home decoration:
Attach wall cloth, table cloth, bed sheet, bedspread, etc.;
3. Non-woven fabric for clothing:
Lining, fusible interlining, wadding, shaped cotton, various synthetic leather base fabrics, etc.;
4. Industrial non-woven fabric:
Filter materials, insulating materials, cement packaging bags, geotextiles, covering cloths, etc.;
5. Non-woven fabrics for agriculture:
Crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.;
6. Other non-woven fabrics:
Space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.
