A kind of super-flexible spunbond non-woven double reinforcement molding process

Abstract

The present invention proposes a supersoft spunbonded non-woven fabric double-reinforcement molding process, which includes the following steps: fully mixing raw materials and feeding them into a hopper, the ratio of each component in the raw materials: polypropylene PP 81-86.5 parts, propylene-based elastic 12.5-16 parts of body, 0.5-1.5 parts of soft masterbatch, 0.5-1.5 parts of titanium dioxide, then melt and filter, and then enter the spinning system, and cool the spun silk through the side cold air to obtain primary growth silk, and process the primary growth silk Air drafting to obtain fiber web, the fiber web is fed into the hot rolling mill for reinforcement under the continuous conveying of the web forming conveyor belt, after hot rolling, it is spunlace reinforced to obtain non-woven fabric, and the non-woven fabric is sprayed with antibacterial antibacterial treatment system Finishing solution, and then input the non-woven fabric into the oven for drying, and use the spunbond spunlace double reinforcement process to replace the traditional hot-air cloth production. The non-woven fabric has the characteristics of fluffy, soft and skin-friendly. The invention adopts a novel processing technology of non-woven fabric, which provides direction for the development of non-woven fabric in the future.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a double-reinforced forming process for supersoft spunbonded non-woven fabrics. Background technique [0002] Non-woven fabrics are non-woven fabrics. It is a non-woven fabric formed by directly using high polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then strengthened by water entanglement, needle punching or hot rolling, and finally finished. Woven cloth. Spunbonded non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the fiber The net becomes a non-woven fabric; spunlace non-woven fabric: it sprays high-pressure fine water onto one or more layers of fiber nets to entangle the fibers with each other, so that the fiber nets can be rein...

Spunbonded non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the fiber The net becomes a non-woven fabric; spunlace non-woven fabric: it sprays high-pressure fine water onto one or more layers of fiber nets to entangle the fibers with each other, so that the fiber nets can be reinforced and have a certain strength. The hand feel of spunlace is not soft enough, while the spunlace non-woven fabric feels comfortable and soft, but its strength is insufficient. A double-reinforced forming process for ultra-soft spunbonded non-woven fabrics is now proposed
