There are many styles of non-woven bags, such as laminating, folding, pressing, hand-held, flat mouth, reinforced hand-held, ultrasonic and so on. I hope I can help you ~ the above are the differences in style, technology and use. Production process classification 1, spunlaced nonwovens spunlace process is to spray high-pressure micro-water on one or more layers of fiber webs, so that the fibers are intertwined and the fiber webs are strengthened and have certain strength. 2. Thermal bonding non-woven fabrics Thermal bonding non-woven fabrics refers to adding fibrous or powdery hot-melt bonding reinforcing materials to the fiber web, and then heating, melting and cooling the fiber web to strengthen it into cloth. 3. Pulp airlaid nonwovens Airlaid nonwovens can also be called dust-free paper and dry papermaking nonwovens. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to bond the fibers to the net curtain, and the fiber net is reinforced into cloth. 4. Wet-process nonwovens Wet-process nonwovens are made by opening fiber raw materials placed in water medium into single fibers, and mixing different fiber raw materials to make fiber suspension slurry, which is conveyed to the web-forming mechanism, and the fibers are web-formed in wet state, and then reinforced into cloth. 5. Spunbonded nonwovens Spunbonded nonwovens means that after the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a net, which is transformed into nonwovens through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. 6. Melt-blown nonwoven process: polymer feeding-melt extrusion-fiber forming-fiber cooling-web forming-reinforced cloth forming. 7. Needle-punched nonwoven fabric Needle-punched nonwoven fabric is a dry nonwoven fabric. Needle-punched nonwovens use the puncture effect of needles to strengthen fluffy fiber webs into cloth. 8. Sewing non-woven fabric Sewing non-woven fabric is a dry non-woven fabric. Sewing method is to make non-woven fabric by reinforcing mesh, yarn layer and non-woven material (such as plastic sheet, plastic thin metal foil, etc.). ) or their combination with warp knitting coil structure. Usage classification can be divided into: 1, non-woven bag series: non-woven environmental protection bag, non-woven handbag, non-woven shopping bag and so on. 2. Non-woven bag series: non-woven file bag, reusable shopping bag, packaging bag and non-woven handbag. 3. Non-woven products series: non-woven storage box, non-woven storage box and non-woven suit cover. 4. Jewelry bag series: gift rope bag, jewelry bag, flannel bag, perfume bottle bag, pen bag and jewelry bag.
