Production line of spunbond pulp-based nonwoven fabric and production technology thereof

Abstract

The invention discloses a production line of spunbond pulp-based nonwoven fabric and a production technology thereof. The production line comprises a third layer assembly line, a second layer assemblyline and a first layer assembly line in an upstream-and-downstream direction, wherein the first layer assembly line comprises a first spunbond production line and a first hot press; the second layerassembly line comprises a cellulose fiber pulp subline and a hot-melt fiber subline; the third layer assembly line comprises a second spunbond production line, a second hot press, a dip finishing container and a discharge finishing nitrogen tank; a third hot press is arranged in the downstream direction of the first layer assembly line; a hot air drying oven is arranged in the downstream directionof the third hot press; a fiber mesh conveying device for conveying a fiber mesh is arranged among the third layer assembly line, the second layer assembly line, the first layer assembly line, the third hot press and the hot air drying oven. The invention further discloses the production technology of the production line. Pollution and waste in the production process of cellulose fiber and in a spunlacing technology can be avoided, and a product has good lipophilicity and hydrophilicity.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a production line and a production process of a lipophilic and hydrophilic nonwoven fabric. Background technique [0002] The spunlace nonwoven process is called spunlace or hydroentangling. The spunlace nonwoven process is to continuously spray the fiber web through high-pressure water flow, and under the action of hydraulic force, the fibers in the fiber web can be moved, displaced, rearranged and entangled with each other, so that the fiber web can be reinforced to obtain certain physical and mechanical properties. [0003] In the United States, popular industrial wiping cloths are generally made of polypropylene spunbonded nonwovens and wood pulp fibers by spunlace. The hydroentanglement process entangles shorter wood pulp fibers evenly and tightly around the spunbond filaments, making them both strong and absorbent. [0004] However, in the series of wood pulp spunlace no...
