Briefly introduce the uses of several non-woven fabric and spunbond non woven fabric equipment

August 31,2023

Non woven fabric,  also known as non-woven fabric, is composed of directional or random fibers and is a new generation of environmentally friendly materials. It has the characteristics of moisture-proof, breathable, flexible, lightweight, non combustible, easy to decompose, non-toxic and non irritating, rich in color, low in price, and recyclable. If polypropylene (PP material) particles are mostly used as raw materials, they are produced through a one-step process of high-temperature melting, spinning, laying, and hot pressing and coiling. It is called cloth due to its appearance and certain properties.

Non woven fabrics can be divided into:

1. Spunlaced non-woven fabric: It sprays high-pressure micro water onto one or multiple layers of fiber mesh, causing the fibers to intertwine with each other, thereby strengthening the fiber mesh and possessing a certain strength

2. Heat bonded non-woven fabric: refers to the addition of fibrous or powdered hot melt bonding reinforcement materials to the fiber mesh, which is then heated, melted, and cooled to form a fabric.

3. Pulp air flow net forming non-woven fabric: also known as dust-free paper or dry papermaking non-woven fabric. It uses airflow mesh forming technology to loosen the wood pulp fiberboard into a single fiber state, and then uses airflow method to aggregate the fibers onto the mesh curtain, and the fiber mesh is reinforced into a cloth.

4. Wet non-woven fabric: It is the process of loosening fiber raw materials placed in a water medium into single fibers, and mixing different fiber raw materials to create a fiber suspension slurry. The suspension slurry is transported to the mesh forming mechanism, and the fibers are formed into a mesh in the wet state and then reinforced into a fabric.

5. Spunbonded non-woven fabric: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, which is then self bonded, thermally bonded, chemically bonded or mechanically reinforced to turn the web into non-woven fabric.

6. Melt blown non-woven fabric: Its process includes polymer feeding - melt extrusion - fiber formation - fiber cooling - mesh formation - reinforcement into fabric.

7. Needled non-woven fabric: It is a type of dry process non-woven fabric that utilizes the puncture effect of a needle to reinforce a fluffy fiber mesh into a fabric.

8. Stitching non-woven fabric: It is a type of dry process non-woven fabric, which uses warp knitted coil structure to reinforce fiber mesh, yarn layer, non-woven materials (such as plastic sheets, plastic thin metal foil, etc.) or their combination to make non-woven fabric.

The uses of non-woven fabrics can be roughly divided into:

(1) Medical and sanitary non-woven fabrics: surgical gowns, protective clothing, disinfection bags, masks, diapers, household cleaning cloths, wiping cloths, wet face towels, magic towels, soft tissue rolls, beauty products, sanitary napkins, sanitary pads, and disposable sanitary cloths;

(2) Non woven fabrics for home decoration: wall coverings, tablecloths, bed sheets, bed covers, etc;

(3) Non woven fabrics for clothing: lining, adhesive lining, wadding, shaped cotton, various synthetic leather bottoms, etc;

(4) Industrial non-woven fabrics; Filter materials, insulation materials, cement packaging bags, geotextiles, wrapping fabrics, etc;

(5) Agricultural non-woven fabrics: crop protection fabrics, seedling raising fabrics, irrigation fabrics, insulation curtains, etc;

(6) Other non-woven fabrics: space cotton, insulation and soundproofing materials, oil absorbent felt, smoke filter tips, tea bags, etc.
