Coloring process for modified polypropylene chemical fiber processing

Abstract

The present invention discloses a coloring process for modified polypropylene chemical fiber processing, and belongs to the technical field of modified polypropylene chemical fiber production processes. According to the coloring process for modified polypropylene chemical fiber processing, a soaking vat used for soaking modified polypropylene chemical fibers is additionally arranged on one side ofa bleaching and dyeing vat, and the soaked modified polypropylene chemical fibers are dewatered and dried, so that the operation process is simplified and the operation efficiency is effectively improved; by cooperation of a winding roller and a dip dyeing roller set, the modified polypropylene chemical fibers are uniformly dip-dyed; the modified polypropylene chemical fibers on the winding roller are guided into dyeing liquid in the bleaching and dyeing vat and are guided up to outside through the dip-dyeing roller set; the dip-dyeing roller set which does opposite rotational motion can remove excess dyeing liquid on the modified polypropylene chemical fibers on one hand and effectively improves the dip-dyeing uniformity of the modified polypropylene chemical fibers on the other hand; and the modified polypropylene chemical fibers penetrate through the dip-dyeing roller set and then are pressed by the dip-dyeing roller set which rotates, so that the permeability of the dyeing liquidto the modified polypropylene chemical fibers is further improved, the coloring effect is effectively improved, and the color fastness of the modified polypropylene chemical fibers is improved.

Description

Technical field [0001] The invention relates to the technical field of cotton chemical fiber production technology, and more specifically, to a coloring process for cotton chemical fiber processing. Background technique [0002] Chemical fiber fabric is a new type of clothing developed in modern times, with many types. Here mainly refers to the pure spinning, blending or interwoven fabric processed by chemical fiber. Among them, cotton fiber is a modified polypropylene fiber. The ultra-cotton fiber underwear, bathrobes, T-shirts and other products developed and produced with it have superior properties such as heat preservation, water absorption, moisture transmission, quick drying, and antibacterial properties, which are high-end fabrics; Chemical fiber has the general superior properties of chemical fiber. It has excellent properties such as high strength, light weight, easy washing and quick drying, good elasticity, and resistance to mildew. [0003] In the production process ...

AI Technical Summary

Problems solved by technology

[0003] In the production process of chemical fiber fabrics, dyeing is an indispensable step. The existing dyeing machines are large in size and can only realize the function of dyeing. However, in the prior art, the dyed object needs to be bleached before dyeing. Cooking and drying, and these mechanical equipment are often set up separately, the operation process is not smooth, resulting in cumbersome operation steps and prolonging the production cycle;

[0004] In addition, the traditional coloring process often uses a rotating dip roller to bring the dye to the passing chemical fiber fabric. The lower end of the dip roller is dipped in the dye, and the dip roller is attached to the dipping tank. The dip roller is rotating. In the middle, the dye is driven upwards through the dipping tank. When the chemical fiber fabric passes through the surface of the dipping tank, the dye solution adheres to the effect of coloring. In this coloring method, the dye on the side of the chemical fiber fabric that is in contact with the dipping tank There is a lot of adhesion, and it is difficult for chemical fiber fabrics to fully contact with the dipping tank, resulting in poor coloring effect, and the color fastness of chemical fiber fabrics is not high
