A coloring process for cotton fiber processing

Abstract

The invention discloses a coloring process for cotton chemical fiber processing, which belongs to the technical field of cotton chemical fiber production technology, and a coloring process for cotton chemical fiber processing. soaked cotton fiber is then dehydrated and dried, which simplifies the operation process and effectively improves the operation efficiency. At the same time, the coordination of the winding roller and the dipping roller group realizes uniform dip-dyeing of the cotton fiber and the cotton on the winding roller The fiber chemical fiber is introduced into the dye liquor in the dyeing vat and then passed through the dipping roller group and exported upward. The dip dyeing roller group rotating in opposite directions can remove the excess dye liquor on the cotton fiber chemical fiber on the one hand, and on the other hand effectively improve the cotton fiber chemical fiber. Dip dyeing uniformity, after the cotton chemical fiber passes through the dip dyeing roller group, it is rolled by the rotating dip dyeing roller group, which further improves the permeability of the dyeing liquid to the cotton fiber chemical fiber, effectively improves the coloring effect, and helps the cotton fiber chemical fiber The color fastness is improved.

Description

technical field [0001] The invention relates to the technical field of cotton chemical fiber production technology, and more specifically relates to a coloring process for cotton chemical fiber processing. Background technique [0002] Chemical fiber fabric is a new type of clothing material developed in modern times, with many types. Here it mainly refers to pure spinning, blending or interlacing fabrics processed from chemical fibers. Among them, cotton fiber is a modified polypropylene fiber, which is used to develop and produce ultra-cotton fiber underwear, bathrobes, T-shirts and other products, which are superior in warmth retention, water absorption, moisture conduction, quick drying, antibacterial and other properties, and belong to high-grade fabrics; Chemical fibers have the general superior properties of chemical fibers, such as high strength, light weight, easy washing and quick drying, good elasticity, and no fear of mildew and moth.

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
