The difference between pp non-woven fabric and spunlace non-woven fabric, PP means that the raw material of the non-woven fabric is PP, and the spunlace non-woven fabric refers to the production process. The two types of non-woven fabric are mainly different in terms of process flow. The fabrics made are not fundamentally different. Now explain the PP non-woven fabric in detail: the exact name of the non-woven fabric should be non-woven fabric, or non-woven fabric. Because it is a kind of fabric that does not require spinning and weaving, it is simply oriented or randomly stretched to form a web structure, and then it is reinforced by mechanical, thermal bonding or chemical methods.
Features of non-woven fabrics • Non-woven fabrics break through traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple raw material sources. The use of non-woven fabrics · Its main uses can be roughly divided into: (1) non-woven fabrics for medical and sanitary use: surgical gowns, protective clothing, disinfection cloths, masks, diapers, civilian wipes, wipes, wet towels, Magic towels, soft towel rolls, beauty supplies, sanitary napkins, sanitary pads and disposable sanitary cloths, etc .; (2) Non-woven fabrics for home decoration: wall coverings, tablecloths, sheets, bedspreads, etc .; (3) clothing Non-woven fabrics: linings, adhesive linings, flakes, shaped cotton, various synthetic leather base fabrics, etc .; (4) industrial non-woven fabrics; filter materials, insulation materials, cement packaging bags, geotextiles, covering cloths, etc. (5) Agricultural non-woven fabrics: crop protection cloth, seedling cloth, irrigation cloth, thermal curtains, etc .; (6) other non-woven fabrics: space cotton, thermal insulation materials, linoleum, smoke filters, tea bags, etc. .
Types of non-woven fabrics · Non-woven fabrics can be divided according to different production processes: 1. Spunlace non-woven fabrics: high-pressure micro-water jets are sprayed onto one or more layers of fiber webs to entangle fibers with each other, thereby The web can be strengthened and strengthened. String 5 2. Heat-sealed non-woven fabric: It refers to adding fibrous or powdery hot-melt bonding and reinforcing materials to the web, and the web is then heated and melted to cool and strengthen the fabric. 3. Pulp air-laid non-woven fabric: It can also be called dust-free paper and dry-process paper-making non-woven fabric. It uses air-laying 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 screen curtain, and the fiber web is then consolidated into a cloth. 4. Wet-laid non-woven fabric: The fiber raw material placed in the aqueous medium is opened into single fibers, and different fiber raw materials are mixed to make a fiber suspension slurry, which is transported to the web forming mechanism, and the fibers are in a wet state. Reinforce it 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 then self-bonded, thermally bonded, chemically bonded, or mechanically strengthened Method to make the web into a non-woven fabric. 6. Meltblown non-woven fabric: its process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- forming into a network --- strengthening into a cloth. 7. Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of puncture needles to strengthen the fluffy web into a cloth. 8. Stitch-knitted non-woven fabric: It is a kind of dry-process non-woven fabric. The stitch-knitting method uses warp-knitted coil structure to make webs, yarn layers, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) Their combination is reinforced to make a non-woven fabric.
