Production process of non-woven bag

Spunlace non-woven spunlace process is to spray high-pressure micro-water into one or more layers of fiber net, so that the fibers are entangled with each other, so that the fiber net can be reinforced and has certain strength. Heat-sealing non-woven heat-bonded non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber net, and then heating, melting, cooling and reinforcing the fiber net to form a cloth. Airflow into the net non-woven fabric can also be called dust-free paper, dry paper Non-woven fabric. It uses the air flow network technology to open the wood pulp fiberboard into a single fiber state, and then uses the air flow method to make the fiber agglutinate on the mesh curtain, and the fiber net is added into the cloth. Wet non-woven wet non-woven fabric is to loosen the fiber raw material placed in the water medium into a single fiber, and at the same time mix different fiber raw materials to prepare fiber suspension slurry, which is transported to the network forming mechanism, the fiber is added into a net in a wet state and then into a cloth. Spunbond non-woven fabric is that 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 subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement, make the mesh into a non-woven fabric. Process of meltblown non-woven fabric: Polymer feeding---Melt Extrusion---Fiber formation---Fiber cooling---Into the net---Reinforce into a cloth. Needle-punched non-woven fabric is a kind of dry non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of needle to reinforce fluffy fiber mesh into cloth. Sewing non-woven sewing non-woven fabric is a kind of dry non-woven fabric. Sewing method is to use warp knitted coil structure to mesh, yarn layer, non-textile material (Such as plastic sheets, plastic thin metal foil, etc) Or their combinations are reinforced to make non-woven fabrics.
