water proof spunbond non woven fabric
1.Water proof spunbond non woven fabric production line The doubling of the water proof spunbond non woven fabric production line refers to the phenomenon that many fibers are entangled together during the process from spinning to forming a non-woven fabric, causing the filament bundles to be consolidated on the surface of the non-woven fabric. In addition to the cohesion and doubling of the primary yarn due to poor quenching air cooling during spinning, there are three main places in the production line where doubling will occur: the nozzle tunnel, the spinning device and the net curtain of the web forming machine. This article introduces the doubling on the mesh curtain of the web forming machine in the water proof spunbond non woven fabric production line. There are three methods of doubling wires on the net curtain of the net forming machine: one is to form parallel wires on the net curtain and roll on the net curtain like a cat's tail; The surface layer of the flakes on both sides of the net curtain at the rear of the web forming machine is flanged. Strictly speaking, the latter two cases do not belong to doubling, but the effect is the same as that of doubling, which affects the surface quality of non-woven fabrics. The parallel phenomenon on the net curtain of the net forming machine is caused by the unbalanced air flow between the upper and lower sides of the net curtain of the net forming machine.
