The non-woven filter cloth is a kind of non-woven cloth, and it is directly applied to a novel fiber product having a soft, breathable war surface structure formed by a variety of web forming methods and consolidation techniques using polymer chips, short fibers or filaments.
It has the characteristics of short process flow, high output, low cost, quick change of types, and universal raw material sources. Non-woven fabrics can be divided into different types according to different consumption technologies:
1, spunlace non-woven fabrics: It is the high-pressure micro-water stream radiated to one or more layers of fiber network, so that the fibers are entangled with each other, so that the fiber network can be reinforced and have a certain strength. The
2. Heat-bonded non-woven fabric: Refers to the participation of fibrous or powdery hot-melt adhesive reinforcement materials in the web, and the web is heated and melted to be cooled and consolidated into cloth. The
3, pulp air-laid non-woven fabrics: also known as clean paper, dry paper non-woven fabrics. It uses the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses the air flow method to agglutinate the fiber on the reticular curtain, and the fiber network is then reinforced into a cloth. The
4. Wet non-woven fabrics: The fiber raw materials placed in an aqueous medium are opened into single fibers, and at the same time, different fiber raw materials are mixed to form a fiber suspension slurry, and the suspension slurry is sent to a network forming mechanism, and the fibers are in a wet state. The net is then reinforced into cloth. The
5. Spun-bonded non-woven fabrics: After the polymer has been extruded and stretched to form a continuous filament, the filaments are laid into a net, and the fiber web is then bonded, thermally bonded, chemically bonded, or mechanically reinforced. Means to make the web into a non-woven fabric. The
6, melt-blown nonwovens: The process: polymer feed --- melt extrusion --- fiber composition --- fiber cooling --- into the network --- reinforcement into cloth. The
7. Needle-punched non-woven fabric: It is a kind of dry non-woven fabric. Acupuncture non-woven fabric is a puncture effect of a needle, and it is used to reinforce loose fabric into a cloth. The
8, stitching non-woven fabric: is a dry non-woven fabric, stitching method is the application of warp stitches structure on the web, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or Their combination stops reinforcement to make a non-woven fabric.
Since nonwoven fabrics have many excellent functional properties, their usefulness is extremely common and can be divided into:
1, clothing with non-woven fabrics;
2, leather, shoes with non-woven fabrics;
3, home decoration, home non-woven fabrics;
4, medical non-woven fabrics;
5, non-woven fabric filter data;
6, industrial non-woven fabrics;
7, non-woven fabrics for the automotive industry;
8, packaging non-woven fabrics;
9, non-woven fabrics for agriculture and horticulture;
10. Military, non-woven fabrics for the defense industry;
11. Non-woven fabrics for other industries
