AI Technical Summary

Technical Problem

In the early color-fixing process of spray-dyed fabrics, the contact between dye and fiber is mainly physical adhesion, which results in some dye failing to form a stable bond with the fiber, leaving floating dye residue and causing staining problems during subsequent processing or use.

Method used

The dyeing process employs a two-stage fixation process. First, the dyed fabric is mixed with a fixation paste for the first fixation, and then mixed with a fixation solution for the second fixation. Combined with washing and drying steps, specific steaming fixation conditions and the water-fixing properties of the paste are utilized to improve the binding stability of the dye and fiber and reduce dye contamination.

Benefits of technology

By employing two color-fixing processes and applying specific conditions, the color-fixing rate of the dye was significantly improved, the staining problem of the fabric was reduced, and the color fastness of the fabric in subsequent treatments was ensured.

Abstract

The invention relates to the field of textile printing and dyeing, in particular to an anti-staining spray-dyed fabric and a preparation method thereof. The preparation method comprises the following steps: S1, preparing a spray-dyed fabric; s2, the spray-dyed fabric is mixed with fixation slurry for primary fixation, intermediate fabric is obtained, and the fixation slurry is prepared from a dyeing auxiliary, paste and water according to the mass ratio of (1-20): (50-80): (50-150); and S3, mixing the intermediate fabric with a color fixing solution, and carrying out secondary color fixing to obtain the anti-staining spray-dyed fabric. In the step S2, a specific amount of slurry locks moisture and provides a continuous and stable moist environment, and a dyeing auxiliary agent optimizes the surface reaction activity of the fabric, accelerates permeation of the dye into fabric fibers, improves the fixation rate of the dye and reduces dye contamination; and in the step S3, the fixation liquid is combined with the unreacted dye to seal the dye, so that the unreacted dye is precipitated, and the staining problem of the spray-dyed fabric is effectively solved.
