Knowledge broadcast: Detailed explanation of the use of non-woven fabrics

Business News, November 3, according to different production processes, non-woven fabrics can be divided into: 1. Spunlace non-woven fabrics: high-pressure fine water jets are sprayed onto one or more layers of fiber nets to make non-woven fabrics according to the production process The differences can be divided into: 　　1. Spunlace: It is to spray high-pressure fine water stream 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: refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and then the fiber web is heated, melted and cooled to form a cloth.　　3. Pulp airlaid: also known as dust-free paper, dry papermaking. 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 method: 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 form a fiber suspension slurry, which is transported to the web forming mechanism, and the fibers are formed into a web in a wet state. Reinforce into cloth. 5. Spunbond: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make The web becomes.　　6. u200bu200bMeltblown: The process: polymer feeding---melt extrusion---fiber formation---fiber cooling---netting---reinforcement into cloth.　　7. Acupuncture: It is a kind of dry method. Acupuncture uses the puncture effect of a needle to reinforce the fluffy web into a cloth. 8. Stitching: It is a kind of dry method. The stitching method uses the warp-knitted loop structure to reinforce the fiber web, yarn layer, non-woven material (such as plastic sheet, plastic thin metal foil, etc.) or their combination , To make. Its main uses can be roughly divided into: 　　 (1) Medical and sanitary use: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, wet face towels, magic towels, soft towel rolls, beauty Supplies, sanitary napkins, sanitary pads and disposable sanitary cloths, etc.; 　　 (2) home decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc.; 　　 (3) clothing: lining, adhesive lining, padding, shaping Cotton, various synthetic leather base fabrics, etc.; 　　(4) industrial use; filter materials, insulating materials, cement packaging bags, geotextiles, covering cloths, etc.; 　　(5) agricultural use: crop protection cloth, seedling cloth, irrigation cloth, Thermal insulation curtains, etc.; 　　(6) Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.　　Characteristics　　 Nonwovens break through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials.
