What are the process classifications of non-woven shopping bags? Non-woven shopping bags can be divided into: 1. Spunlace: the high-pressure fine water flow is sprayed onto a layer or a multi-layer fiber net to tie the fibers together, so that the fiber net can be reinforced and has a certain strength. 2. Heat-sealing non-woven bag: refers to adding fiber-like or powdery hot-melt bonding reinforcement materials to the fiber net, and the fiber net is heated, melted, cooled and reinforced into cloth. 3, pulp airflow into a net non-woven bag: can also be called clean paper, dry paper Non-woven fabric. It uses the airflow forming technology to loosen the wood pulp fiberboard into a single fiber state, and then uses the airflow method to make the fiber agglomerate on the mesh curtain, and the fiber mesh is added to the cloth. 4. Wet non-woven bag: it is to loosen the fiber raw materials placed in the water medium into single fibers, and at the same time mix different fiber raw materials to make fiber suspension slurry, which is transported to the mesh forming mechanism, the fiber is made into a net and then fixed into a cloth in a wet state. 5. Spunbonded non-woven bag: After the polymer has been extruded and stretched to form a continuous filament, the filament is laid into a net, and the fiber net is then bonded, hot bonded, chemical bonded or mechanical. Reinforcement method, make the fiber mesh into a non-woven fabric. 6, melt spray non-woven bag: its process: Polymer feeding---Melt Extrusion---Fiber formation---Fiber cooling---Net---Reinforced into cloth. 7, acupuncture: is a kind of dry non-woven fabric, acupuncture non-woven fabric is to use the puncture effect of the needle to reinforce the fluffy fiber net into a cloth. 8. Sewing: it is a kind of dry non-woven fabric. The sewing method is to use the warp knitting coil structure to pair fiber mesh, yarn layer and non-textile materials (For example, plastic sheets, plastic thin metal foil, etc) Or their assemblies are reinforced to make non-woven fabrics.
