Basic introduction to non woven fabrics

What are the types of non woven material? Non woven fabric can produce non-woven fabrics for different purposes according to the production process. Synwin non woven fabric manufacturer will give you a detailed introduction.

The non-woven fabric has no warp and weft threads, so it is very convenient to cut and sew, and it is light in weight and easy to shape. According to the application requirements, non woven materials are divided into two categories: disposable application type and durable type.

According to the production process of non woven material is divided into:

 1. Spunlace non woven cloth: The spunlace process is to spray high-pressure micro water jets onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs are reinforced and have a certain force.

 2. Heat-bonded non woven cloth: Heat-bonded non-woven fabric refers 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 material: Air-laid non-woven fabrics can also be called clean paper and dry-laid non-woven fabrics. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to condense the fibers on the web-forming curtain, and the fiber web is then reinforced into a cloth.

4. Wet-laid non-woven fabric: Wet-laid non woven cloth is to open fiber raw materials placed in an aqueous medium into single fibers, and at the same time mix different fiber raw materials to make fiber suspension pulp. In the wet state, it is formed into a net and then reinforced into a cloth.

5. Spunbond non-woven fabric: Spunbond non woven material is after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then self-bonded, thermally bonded, chemically bonded Or mechanical reinforcement methods to turn the web into a non-woven fabric.

6. Meltblown non woven cloth: The process of meltblown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling---web forming---reinforcement into cloth.

7. Acupuncture non-woven material: Acupuncture non woven material is a kind of dry-laid non-woven fabric. Acupuncture non-woven fabric uses the puncture effect of a needle to reinforce the fluffy fiber web into cloth.

 8. Stitch-bonding non-woven fabric: Stitch-bonding non woven cloth is a kind of dry-laid non-woven fabric. The stitch-bonding method uses the warp-knitted coil structure to stitch the fiber web, yarn layer, and non woven materials (such as plastic sheets, plastic thin metal foils, etc.) etc.) or their combination for reinforcement to make non woven material.

 9. Hydrophilic non-woven fabric: mainly used in the production of medical and sanitary materials to achieve better hand feel and not scratch the skin. For example, sanitary napkins and sanitary pads use the hydrophilic function of hydrophilic non-woven fabrics.

The following Synwin non woven fabric manufacturer will introduce the

1. Light weight: Polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, only three-fifths of cotton, with fluffy and good hand feeling.

2. Non-toxic and non-irritating: The product is produced with FDA-compliant raw materials, does not contain other chemical components, has stable performance, is non-toxic, has no peculiar smell, and does not irritate the skin.

3. Antibacterial and anti-chemical agents: Polypropylene is a chemically passive substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and finished products do not affect the strength due to erosion.

4. Good physical properties. It is made of polypropylene spun directly into a mesh and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional, and the vertical and horizontal strengths are similar.

5. In terms of environmental protection, the raw material of most of the non woven material used is polypropylene, while the raw material of plastic bags is polyethylene. Although the two substances have similar names, they are quite different in chemical structure. The chemical molecular structure of polyethylene is quite stable and difficult to degrade, so it takes 300 years for plastic bags to decompose; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, so that it can be effectively degraded , and enter the next environmental cycle in a non-toxic form, a non woven cloth shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the pollution to the environment after disposal is only 10% of that of plastic bags.
