The exact name of non-woven fabric should be non-woven fabric

Because it is a kind of fabric that does not need to be spun and weaves, it just aligns or randomly arranges the textile short fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical methods to strengthen it.


Non-woven fabric breaks through the traditional textile principles, and has the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials. Its main uses can be roughly divided into: (1) Medical and sanitary cloths: surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc.; (2) Home decoration cloths: wall coverings, table cloths, bed sheets, bedspreads, etc.; (3) Follow-up cloths : Lining, fusible lining, wadding, shaped cotton, various synthetic leather base fabrics, etc.; (4) Industrial fabrics: filter materials, insulating materials, cement packaging bags, geotextiles, covering fabrics, etc.; (5) Agriculture Cloth used: crop protection cloth, seedling cloth, irrigation cloth, thermal insulation curtain, etc.; (6) Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.


Types of non-woven fabrics


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


1. Spunlace non-woven fabric: It sprays high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength.


2. Heat-bonding non-woven fabric: refers to adding fibrous or powdery hot-melt bonding reinforcement material to the fiber web, and the fiber web is heated, melted and cooled to reinforce into a cloth.


3. Pulp air-laid non-woven fabric: also known as dust-free paper and dry-laid non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the web curtain, and then reinforce the fiber web into a cloth.


4. Wet-laid non-woven fabric: It is to open the fiber raw materials placed in the water medium into single fibers, and at the same time, mix different fiber raw materials to make a fiber suspension slurry. The suspension slurry is transported to the web forming mechanism. In the wet state, a net is formed and then reinforced into a cloth.


5. Spunbond non-woven fabric: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is bonded by itself, thermally, and chemically. Or mechanical reinforcement method to make the web into a non-woven fabric.


6. Melt-blown non-woven fabric: its technological process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- netting --- reinforcement into cloth.


7. Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric uses the puncture effect of a needle to reinforce the fluffy web into a cloth.


8. Stitched non-woven fabric: It is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to align the fiber web, yarn layer, and non-woven materials (such as plastic sheet, plastic thin metal foil). Etc.) or their combination to be reinforced to make a non-woven fabric.
