What is the difference between a non-woven fabric and a non-woven fabric?

Dependency: Non-woven fabrics are a kind of non-woven fabrics.

Non-woven fabric is a non-spinning, woven fabric, the textile short fiber or filament orientation or random arrangement to form a fiber network structure, and then through mechanical, thermal bonding or chemical methods such as reinforcement. In short, it is not a thread that is intertwined. Is the use of physical methods directly paste the fiber. Therefore, when you get the adhesive in your clothes, you will find that a thread cannot be pulled out. The non-woven fabric breaks through the traditional textile principle and has a short process flow, fast production speed, high output, and low cost., Wide use, many sources of raw materials.

The main uses include:

(1) Medical and sanitary cloth: surgical gowns, protective clothing, disinfection cloth, masks, diapers, female sanitary napkins, etc;

(2) Home decoration cloth: wall covering, tablecloth, bed sheet, bedspread, etc.

(3) Packaging cloth: lining, adhesive lining, cotton, cotton, all kinds of synthetic leather bottom, etc;

(4) Industrial cloth: filter material, insulation material, cement packaging bag, geotextile, covering cloth, etc;

(5) Agricultural cloth: crop protection cloth, seedling cloth, irrigation cloth, insulation curtain, etc;

(6) Others: space cotton, thermal insulation materials, smoking felt, cigarette filters, tea bags, etc.

classification of nonwoven:

1. Spunlace non-woven fabric

The water hammer process is to spray high-pressure fine water into one or more layers of fiber web, so that the fibers are entangled with each other, thereby reinforcing the fiber web and making it have a certain strength.

2. Heat-bonding non-woven fabric

Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcing material into the fiber web, and reinforcing the fiber web with cloth after heating and melting and cooling.

3. Residue air-laid non-woven fabric

Air-laid non-woven fabric, also known as dust-free paper and dry-process paper-making non-woven fabric, uses air-laid technology to relax the wood pulp fiber board into a short fiber state, and then uses air-flow method to condense the fibers on the mesh curtain and re-reinforce the fiber net to make cloth.

4. Wet-laid non-woven fabric

Wet-laid non-woven fabric is to loosen the fiber raw materials in the water medium into short fibers, and at the same time mix different fiber raw materials to make fiber suspension slurry, and the suspension slurry is transported to the mesh forming mechanism, and the fibers are netted in the wet state and then reinforced with cloth.

5. Woven non-woven fabric

Spinning non-woven fabric means that after the polymer has been extruded and stretched to form continuous filaments, the filaments are wrapped in a mesh, and the fiber web is then self-bonded, thermally bonded, chemically bonded or mechanically reinforced. The fiber web is made into a non-woven fabric.

6. Melt jet non-woven fabric

Dissolving process of non-woven fabric spraying: polymer feeding-melt extrusion-fiber formation-fiber cooling-web formation-reinforcing cloth.

7. Needle-punched non-woven fabric

Needle-punched non-woven fabric is a dry type non-woven fabric, and the needle-punched non-woven fabric is made by using the effect of needle punching to reinforce the scattered fiber network into cloth.

8. Sewing non-woven fabric
