Fabric pattern transfer ink and preparation method thereof

Abstract

The invention discloses a fabric pattern transfer ink which comprises the following components in percentage by weight: 0.1-40wt% of dye, 1-50wt% of binder and 10-98.9wt% of solvent, wherein the binder is water-soluble hot-melt resins, and the solvent is water, or an organic solvent or a mixture of the water and organic solvent. The invention also discloses a preparation method of the fabric pattern transfer ink, a fabric pattern transfer method using the ink and a fabric pattern transfer film. Compared with the prior art, large-scale industrial production of the heat transfer printing film or heat transfer printing paper of a fabric is possible through the invention, the production cost is greatly reduced, the production efficiency is remarkably improved, and the comprehensive popularization of the technology is facilitated. Moreover, the coating thickness of the prior art is also reduced, even the coating process can be saved, the equipment investment cost is lowered, and the manufacturing process is shortened.

Description

technical field [0001] The invention belongs to the field of fabric printing and dyeing, in particular to a fabric pattern transfer ink and a preparation method thereof. Background technique [0002] The traditional thermal transfer printing method for textiles began in the late 1960s. It is a printing method in which the easily sublimated disperse dyes are first printed on the transfer backing paper, and then the disperse dyes are sublimated and transferred to the fabric by hot pressing and other methods to form patterns. It has the advantages of realistic pattern, simple process, less discharge of three wastes and so on. It is only suitable for printing on polyester fabrics, and it does not work well on nylon, acrylic, and natural fiber fabrics. [0003] In order to realize the transfer printing of natural fibers, the wet transfer printing of reactive dyes and acid dyes has attracted the attention of many printing and dyeing workers at home and abroad.

AI Technical Summary

Problems solved by technology

The connecting material in printing ink is usually called resin. Chinese patent 200810196039.X provides a variety of polymer resins that can be used for the connecting material of wet transfer dye gravure ink. Although the resin part provided has It must be hot-melt, but not water-soluble. Although the printing ink composed of them can be transferred to the fabric well during heat transfer, it cannot be removed by washing, causing the pattern to feel hard.

And because there is no water solubility, the dye cannot be completely released during steaming or cold stacking, resulting in light color, high dye concentration in wastewater, and easy staining on the white background

Therefore, in the prior art, this layer of dense dye layer will isolate the hot-melt coating during high-temperature thermal transfer, so that the dye cannot be well attached to the fiber and affect the effect of transfer printing.

Or on the final product, because the resin is not water-soluble, it cannot be removed by washing, causing the finished product to feel hard and lose its use value
