What are the types of non-woven fabrics according to different production processes?
Edit:Anhui Xingfu Plastic Industry Co., Ltd.   UpDate:2020-03-30

These two kinds of non-woven fabrics are mainly different from the craftsmanship, and the specific fabrics are basically different. Now explain in detailPP non-woven fabric: The exact name of non-woven fabric should be non-woven fabric, or called non-woven fabric. Because the formation of woven fabrics and fabrics is needed, short fibers or filaments are oriented or randomly supported to form a fiber structure, and then mechanical, thermal or chemical methods such as reinforcement are used.

According to different production processes, non-woven fabrics can be divided into:

1. Spunlace non-woven fabric: high-pressure fine water is sprayed onto one or more layers of fiber webs to entangle the fibers and strengthen the web with a certain strength.

2. Thermal bonding non-woven fabric: refers to the fiber or powdered hot melt adhesive reinforcement material in the fiber, which is then heated and cooled to form a fabric.

3. Pulp air-forming non-woven fabric: also called clean paper, dry paper non-woven fabric. The airflow technology is used to open the wood pulp fiberboard into a single fiber state, and then the airflow method is used to condense the fibers into curtains, and the fiber mesh is then reinforced.

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 make fiber suspension pulp. The suspension pulp is transported to the network organization, and the fibers enter the network when wet, and then strengthen the cloth.

5.Spunbond non-woven fabric: The polymer has been extruded, stretched and formed into continuous filaments, the filaments are laid into a net, and the fiber net is then made into a non-woven fabric through its own bonding, thermal bonding, chemical bonding or mechanical reinforcement.

6. Melt-blown non-woven fabric: Process: polymer feeding --- melt extrusion --- fiber forming --- fiber cooling --- into the net- strengthening into cloth.

7. Acupuncture non-woven fabric: dry non-woven fabric, acupuncture non-woven fabric is punctured by a puncture needle, and fluffy fiber is reinforced into a fabric.

8. Sewing non-woven fabric: It is a dry non-woven fabric, the sewing method is a network of warp-knitted loop structure, yarn layer, non-woven material (such as plastic sheet, plastic thin metal foil, etc.)) or Their combination is reinforced to form a non-woven fabric.
