Introduction to the use and classification of non-woven fabrics

Different raw materials and processing techniques determine the different uses of non-woven products. Different types of non-woven fabrics have different requirements for raw materials and processing techniques. Among them, different types of non-woven fabrics are different in thickness and technical indicators. Next, the use and classification of non-woven fabrics will be introduced in detail. The use and classification of non-woven fabrics: 　　 non-woven use introduction: 　　1, non-woven fabrics for clothing: lining, fusible interlining, wadding, styling cotton, various synthetic leather base fabrics, etc.; 　　2, industrial non-woven fabrics ; Filter materials, insulating materials, cement packaging bags, geotextiles, covering fabrics, etc.; 　　3, medical and sanitary non-woven fabrics: surgical gowns, protective clothing, disinfection disposable non-woven fabrics, masks, diapers, civilian use Wipes, wipes, wet face towels, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads, and disposable sanitary cloths, etc.; 　　4. Non-woven fabrics for garden decoration: wall coverings, table cloths, bed sheets, Bed cover, etc.; 　　5, agricultural non-woven fabrics: crop protection cloth, seedling cloth, irrigation cloth, thermal insulation curtain, etc.; 　　6, other non-woven fabrics: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc. .　　 Introduction to the classification of non-woven fabrics: 　　1. Thermally bonded non-woven fabric 　　 Thermally bonded non-woven fabric refers to the addition of fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is heated, melted and cooled to reinforce the fabric.　　2. Pulp airlaid nonwoven fabric 　　Airlaid nonwoven fabric can also be called dust-free paper and dry papermaking nonwoven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-flow method to agglomerate the fibers on the web curtain, and then strengthen the fiber web into a cloth.　　3. Spunlace non-woven fabric 　　The spunlace process is to spray a high-pressure fine water stream onto one or more layers of fiber webs to entangle the fibers with each other, so that the web can be reinforced and have a certain strength. 4. Wet-laid non-woven fabrics Wet-laid non-woven fabrics are used to open fiber raw materials placed in an aqueous medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to the web forming mechanism, and the fiber In the wet state, a net is formed and then reinforced into a cloth.　　 5. Melt-blown non-woven fabric 　 　 Melt-blown non-woven fabric process: polymer feeding-melt extrusion-fiber formation-fiber cooling-net formation-reinforcement into the cloth.　　6. u200bu200bNeedle-punched non-woven fabrics 　　 Needle-punched non-woven fabrics are a type of dry-laid non-woven fabrics. Needle-punched non-woven fabrics use the puncture effect of needles to reinforce the fluffy web into a fabric. 7. Spunbond non-woven fabric Spunbond non-woven fabric is formed 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, and chemically bonded. Combination or mechanical reinforcement method to make the web into a non-woven fabric. 8. Stitched non-woven fabrics Stitched non-woven fabrics are a kind of dry-laid non-woven fabrics. The stitching method uses the warp-knitted loop structure to align the fiber web, yarn layers, and non-woven materials (such as plastic sheets, plastic thin metal Foil, etc.) or their combination is reinforced to make a non-woven fabric. The above is a detailed introduction of the use and classification of non-woven fabrics. Different types of non-woven fabrics are usually classified according to their uses. Common types of non-woven fabrics include needle punched non-woven fabrics, spunlace non-woven fabrics, and spunbonded fabrics. Non-woven fabrics, etc., different types of non-woven fabrics also have very different uses. Previous post: Where are there many non-woven fabric factories in Fujian?
