Embodiment 1

[0036] A kind of reactive polymer dye ink is applied to the ink-jet printing printing and dyeing process on the cotton fabric, comprises the following steps,

[0037] 1) Cotton fabric reactive dye printing pretreatment:

[0038] Singeing, mercerizing, open-width continuous bleaching, biological enzyme polishing, and three mercerizing treatments are performed on the knitted gray fabric in order to obtain cotton knitwear; singeing can remove the fluff on the surface of the cotton yarn, and make the surface of the cotton knitted fabric smooth and clean. Smooth, clear texture, mercerized treatment provides a high level of gray fabric for reactive dye printing, the process conditions of mercerized treatment:

[0039]

[0040] Process conditions of biological enzyme polishing:

[0041]

[0042] Bioenzyme polishing is to use biological enzymes to remove surface substances of gray cloth, so that the gray cloth is anti-pilling, soft and fluffy, and the effect of bio-polishing fi...

Abstract

The invention provides an active polymer dye ink and applications of the active polymer dye ink in an ink jet printing and dyeing process for cotton fabrics. A purpose of the present invention is to solve the problems of low washing fastness and poor brilliance of the ink in the prior art. According to the present invention, the active polymer dye ink is prepared by carrying out a homogeneous grafting reaction on N,O-carboxymethyl chitosan as a polymeric dye skeleton and an active dye in an aqueous solution, wherein the active dye is formed by compounding an X-type active dye and a F-type active dye, and a molar ratio of the N,O-carboxymethyl chitosan to the active dye is 7-4:1; and the active dye molecules are grafted onto the skeleton of the N,O-carboxymethyl chitosan, such that the migration and the penetration of the active dye molecules are less so as to provide excellent performances of no toxicity, safety and convenient use.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a reactive polymer dye ink and an inkjet printing and dyeing process applied to cotton fabrics. Background technique [0002] Inkjet printing inks are generally composed of pigments, water or organic solvents, and additives. Inkjet printing inks for fabrics are not only concerned with the purity of pigments, the particle size of insoluble solid particles, and the viscosity, surface tension, stability, pH, and foaming properties of inks. In addition to specific requirements, it is also required that after the ink is sprayed onto the fabric to form a pattern, it must have good color fastness such as washing resistance. At present, according to the solvent used to prepare the ink, textile digital inkjet printing ink can be Divided into water-based inks and solvent-based inks, water-based inks are further divided into small molecule dye inks and polymer dye inks, small mo...
