Salt-free low-alkali dyeing treatment system and method for shortening dyeing time of reactive dye

Abstract

The invention discloses a salt-free low-alkali dyeing treatment system and method for shortening dyeing time of reactive dye, and relates to the technical field of textile printing and dyeing. The salt-free low-alkali dyeing treatment system comprises a box body. A first cloth roller and a second cloth roller drive cloth to penetrate through the interior of a spray dyeing mechanism, a second water pump pumps out blended dye liquid in a constant-temperature dye tank, then the dye liquid is conveyed into an upper material spraying plate and a lower material spraying plate through a pipeline, then the dye liquid is evenly sprayed on the upper surface and the lower surface of the cloth through a plurality of spraying head assemblies, so that the purpose of even and rapid printing and dyeing is achieved; the cloth drives an upper extrusion roller and a lower extrusion roller to rotate when passing through the space between the upper extrusion roller and the lower extrusion roller, and the cloth is evenly extruded by the upper extrusion roller and the lower extrusion roller in the passing process, so that redundant dye in the cloth is extruded and the purpose of saving the dye is achieved; and in the process of extruding the cloth, the redundant dye in the cloth is extruded and flows into a recycling box through a seepage opening, and the dye collected in the recycling box is conveyed into the constant-temperature dye tank through a first water pump to be reused.

Description

Technical field [0001] The present invention relates to the technical field of textile printing, particularly with reactive dyes in order to shorten the time of dyeing a low alkali salt-free processing system and method. Background technique [0002] Reactive dyes known as reactive dyes, is the emergence of the 1950s a new class of water-soluble dyes, reactive dyes contain reactive groups in the molecule reactive with cellulose hydroxyl groups and amino groups in the protein fiber dyeing fiber form a covalent bond, generating a "dye - fiber" compound. Reactive dyes having a bright color, good leveling, simple staining method, high color fastness, complete chromatography and low cost characteristics, mainly used in the dyeing of cotton, hemp, viscose, silk, wool and other fibers and blended fabric and printing. [0003] However, the conventional dip equipment, all of the fabric is placed in the vat, stirring dyeing cloth, but in the dyeing process can not be placed inside the vat ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a salt-free and low-alkali dyeing treatment system and method that shortens the dyeing time of reactive dyes, which solves the need for batch dyeing in the traditional printing and dyeing textile dyeing process, which cannot be dyed continuously and cannot be dyed after dyeing. Problem with collecting excess dye on cloth
