Non-woven properties:

Non-woven fabric is a kind of non-woven fabric, which directly uses high polymer chips, short fibers or filaments to pass the fibers through airflow or mechanical netting, and then reinforced by hydroentanglement, needle punching, or hot rolling, and then finished by finishing. A non-woven fabric. A new type of fiber product with soft, breathable and flat structure, the strength is not to produce lint, strong, durable, silky soft, and also has a cotton feel, compared with cotton fabric, the non-woven bag is simply formed, And the cost is cheap.

Non-woven features: durability, one-off. Insulated, conductive. Softness, stiffness. Fineness, swelling. Isotropic, anisotropic. Filterable, breathable and impervious. Elasticity, stiffness. Light, loose, warm. Thin as a flap, thick as a felt. Waterproof and moisture permeable. Ironed, stitched, molded. Flame retardant, antistatic. Water permeable, waterproof, abrasion resistant, and napped. Resistant to wrinkles, good elasticity, high moisture absorption, water repellency.

1. Light weight: Polypropylene resin is the primary production material, the proportion is only 0.9, as long as three-fifths of cotton, loose, feel good.

2. Soft: Made of fine fiber (2-3D), light-point hot melt bonding. The product is soft and comfortable.

3. Water and ventilation: polypropylene chips do not absorb water, the water content is zero, the product has good water repellency, and it is made of pure fiber with porosity, good gas permeability, easy to keep the cloth dry and easy to wash.

4. Non-toxic, non-influence: The product is produced in accordance with FDA food grade materials, does not contain other chemical components, has stable function, is non-toxic, has no odor, and does not affect the skin.

5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, which is free of insects and can isolate the corrosion of bacteria and insects in liquids; antibacterial and alkali corrosion, and products do not affect the strength due to corrosion.

6, antibacterial. The product has water-extracting properties, is not moldy, and can isolate the corrosion of bacteria and insects in the liquid, and is not mildewed.

7, good physical properties. It is made by directly spinning polypropylene into a mesh, and the strength of the product is better than that of the general staple fiber product, the strength is non-directional, and the longitudinal and transverse strengths are similar.

8. In terms of environmental protection, the original material of most non-woven fabrics used today is polypropylene, and the original information of plastic bags is polyethylene. Although the two substances have similar names, they have far different chemical structures. The chemical molecular structure of polyethylene has a moderately strong stability and is extremely difficult to degrade. Therefore, it takes 300 years for the plastic bag to be differentiated. The chemical structure of polypropylene is not strong, the molecular chain is simple to crack, and then it can be effectively degraded. And in the non-toxic form into the next environmental cycle, a non-woven shopping bag can be completely differentiated within 90 days. And the non-woven shopping bag can be reused more than 10 times, and the environmental pollution is only 10% of the plastic bag after disposal.

Depending on the production process, non-woven products can be divided into:

1. Spunlace non-woven fabric: The spunlace process is to spray a high-pressure fine water stream onto one or more layers of fiber webs, so that the fibers are entangled with each other, and then the web is reinforced to have a certain strength.

2. Heat-bonded non-woven fabric: Thermally-bonded non-woven fabric refers to the fiber-reinforced or powdered hot-melt bonding reinforcement material in the fiber web, and the fiber web is then reinforced by heating and melting to form a cloth.

3, pulp airlaid non-woven fabric: airlaid non-woven fabric can also be called dust-free paper, dry papermaking non-woven fabric. It uses the air-laid technology to open the wood pulp fiber board into a single fiber condition, and then uses the air flow method to agglomerate the fibers on the mesh curtain, and the fiber web is further reinforced into a cloth.

4. Wet-laid non-woven fabric: The wet-laid non-woven fabric is to open the fibrous material placed in the aqueous medium into a single fiber, and to mix the different fiber materials to form a fiber suspension slurry, and the suspended pulp is transported to the networked structure. The fibers are netted in a wet state and then reinforced into a cloth.

5, spunbond non-woven fabric: spunbond non-woven fabric is after the polymer has been extruded, stretched to form a continuous filament, the filament is laid into a net, and the web is then bonded by itself, thermally bonded, chemical Bonding or mechanical reinforcement to make the web into a non-woven fabric.

6. Meltblown non-woven fabric: melt-blown non-woven fabric process: polymer feeding---melt extrusion---fiber composition---fiber cooling---forming into the net---reinforcing into cloth.

7. Needle-punched non-woven fabric: Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric is a puncture effect using a lancet, and the loose fiber web is reinforced into a cloth.

8. Non-woven fabric: Non-woven fabric is a kind of dry non-woven fabric. The stitching method uses warp-knitted coil structure, web, yarn layer and non-woven materials (such as plastic sheet, plastic sheet). The metal foil or the like or a combination thereof is reinforced to form a nonwoven fabric.
