What is non-woven fabric?

· The exact name of non-woven fabric should be non-woven fabric, or non-woven fabric. Because it is a fabric that does not require spinning and weaving, it is just oriented or randomly braided short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.

The characteristics of non-woven fabrics · Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many raw material sources.

The use of non-woven fabrics · Its main uses can be roughly divided into:
(1) Medical and sanitary non-woven fabrics: surgical gowns, protective clothing, sterilization wraps, masks, diapers, civilian wipes, wipes, wet wipes, magic towels, soft towel rolls, beauty supplies, sanitary napkins, sanitary Pads and disposable sanitary cloths, etc .;
(2) Non-woven fabrics for home decoration: wall stickers, tablecloths, bed sheets, bed covers, etc .;
(3) Non-woven fabrics for clothing: lining, adhesive lining, flakes, shaped cotton, various synthetic leather base fabrics, etc .;
(4) Industrial non-woven fabrics; filter materials, insulation materials, cement packaging bags, geotextiles, covering cloths, etc .;
(5) Agricultural non-woven fabrics: crop protection fabrics, seedling raising fabrics, irrigation fabrics, thermal insulation curtains, etc .;
(6) Other non-woven fabrics: space cotton, thermal insulation and sound insulation materials, linoleum, cigarette filter, tea bags, etc.

Types of non-woven fabrics · Non-woven fabrics can be divided into:
1. Spunlace non-woven fabric: it is to spray high-pressure micro-water flow onto one or more layers of fiber mesh to make the fibers entangle with each other, so that the fiber mesh can be strengthened and has a certain strength.
2. Heat-sealed non-woven fabric: it refers to adding fibrous or powdery hot-melt bonding and reinforcing materials to the fiber web, and then the fiber web is heated, melted, cooled and consolidated into 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 the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses the air-flow method to condense the fibers on the screen forming curtain, and then the fiber web is consolidated 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, and the suspension slurry is transported to the web forming mechanism, and the fibers are in a wet state The net is then reinforced into cloth.
5. Spunbond nonwoven fabric: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a net, and the fiber web is then self-bonded, thermally bonded, chemically bonded or mechanically strengthened Method to make the web into a non-woven fabric.
6. Melt-blown non-woven fabric: Its technological process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- net formation --- reinforcement into cloth.
7. Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of the needle to strengthen the fluffy web into a cloth.
8. Stitch-bonded non-woven fabric: It is a kind of dry-laid non-woven fabric. The stitch-bonded method is to use warp-knitted coil structure to web, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or Their combination is reinforced to make a non-woven fabric.
