Preparation method of polypropylene spun-bonded non-woven fabric

Abstract

The invention relates to a preparation method of a polypropylene spun-bonded non-woven fabric. A polypropylene spun-bonded non-woven fabric preparation device is used, and the polypropylene spun-bonded non-woven fabric preparation device comprises a bottom plate, a printing and dyeing pool, a winding mechanism, a vibration mechanism and a drying mechanism. The multi-layer polypropylene spun-bonded non-woven fabric is placed in a three-dimensional mode through the winding mechanism, so that multiple layers of the polypropylene spun-bonded non-woven fabric can be dip-dyed at the same time, and dip dyeing efficiency is improved; and meanwhile, the vibration mechanism is adopted to drive the polypropylene spun-bonded non-woven fabric to move up and down in the dip dyeing pool, dip dyeing liquid enters grid holes under the impact of up-down movement force of the polypropylene spun-bonded non-woven fabric, and therefore, the dip dyeing effect of the polypropylene spun-bonded non-woven fabric is improved.

Description

technical field [0001] The invention relates to the technical field of polypropylene spunbonded nonwoven fabric preparation, in particular to a preparation method of polypropylene spunbonded nonwoven fabric. Background technique [0002] Polypropylene is a polymer formed by the addition polymerization of propylene. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, pipelines, chemical containers, etc., and is also used in food and drug packaging. After extruding and stretching the polymer formed by polypropylene 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 web become Spun-bonded non-woven fabric, good high temperature resistance and low temperature resistance (polypropylene can be used for a long time in the environment of 150 ℃, and polyester can be us...

AI Technical Summary

Problems solved by technology

[0003] 1. When printing and dyeing common polypropylene spunbonded nonwoven fabrics, due to the large number of mesh holes on polypropylene spunbonded nonwoven fabrics, it is difficult for the liquid to carry out the dyeing process in the mesh holes of polypropylene spunbonded nonwoven fabrics. Exhaust dyeing, which makes the effect of exhaust dyeing of polypropylene spunbonded non-woven fabrics poor;

[0004] 2. When dip-dyeing polypropylene spunbond non-woven fabrics, since the multi-layer dip-dyeing effect of polypropylene spunbond non-woven fabrics is not good, most of them use a single layer for dip-dyeing, which makes the polypropylene spunbond non-woven fabrics more efficient. Low
