Problems solved by technology

[0002] Disperse dyes are the main colorants for dyeing and printing polyester fabrics. Their molecular structure is simple, their molecular weight is small, and they have no reactive groups. They have low affinity for cotton fibers, so they cannot be directly applied to the dyeing and printing of cotton fabrics.
In order to realize the transfer printing of disperse dyes on cotton fabrics, scientific and technological workers at home and abroad have done a lot of research work and made some progress, mainly focusing on the modification of cotton fabrics, such as coating the surface of cotton fabrics Polymerized polymer film or expanded cotton fiber and other methods to improve the dyeing rate and color fixing performance of disperse dyes, the more common method is to cover a layer of polymerized polymer film on the surface of cotton fabric, so that sublimated disperse dyes can be fixed on the polymer film Obviously, this method needs to pretreat the cotton fabric before transfer printing, and will also produce a large amount of transfer waste paper in production, and at the same time, the covering effect of the polymer film will also affect the quality of the printed fabric. Moisture absorption and breathability

Abstract

The invention discloses disperse dye ink for cotton fabric inkjet printing and a preparation method thereof. The ink consists of the following components in parts by weight: 30-50 parts of emulsion particle nano composite pigment, 20-35 parts of cosolvent, 0.5-2.0 parts of surfactant, 0.4-1.2 parts of pH regulator, 0.1-0.3 part of bactericide and the balance of deionized water based on 100 parts. The prepared disperse dye ink can be directly inkjet-printed on the cotton fabric; after high-temperature treatment, the disperse dye is sublimated and fixed on the thin polymer film on the cotton fabric surface so as to finish the inkjet printing. By adopting the ink, direct transfer printing of the disperse dye on the cotton fabric is realized, and the waste paper generated in the transfer printing process is avoided. The ink disclosed by the invention has the advantages of no change of color phase of original dye, high brightness, good fastness and the like.
