Technical Field

The invention relates to a printing and dyeing technology, in particular to a transfer printing method of a textile.

Background

The transfer printing is to print dye pigment on transfer printing paper, transfer printing and heat treatment to transfer the dye in the pattern to the textile and fix the dye to form the pattern. The most widely used transfer printing method is dry transfer of disperse dyes onto synthetic fiber fabrics. The method is that the disperse dye, paste powder, alcohol, benzene and other solvent are first selected and mixed with resin to form ink, and the ink is printed onto tough paper to form transfer paper. When printing, the surface of the transfer paper with patterns is overlapped with the fabric, and the fabric is hot pressed for about 1min at high temperature (220 ℃), so that the disperse dye is sublimated to be changed into gas, and the gas is transferred to the fabric from the paper. After printing, no water washing treatment is needed, so that no sewage is produced, and the effects of bright color, clear gradation and delicate flower shape can be obtained.

However, the existing ecological problem is that a large amount of transfer paper is needed during printing and dyeing, and the transfer paper is difficult to recycle after printing, which causes serious resource waste.

Therefore, a new solution is needed to solve this problem.

s7: putting the textile in a second water tank after leaving the first water tank, wherein the second water tank is also clear water, the temperature of the water in the second water tank is normal temperature, and soaking the textile in the second water tank for 10 minutes;

s8: and taking the wet textile out of the water tank II, and performing washing, dewatering and drying work.

The invention is further configured to: the dispersing agent comprises 20-45% of fatty alcohol-polyoxyethylene ether, 20-31% of polyvinyl acetate, 5-13% of hydrochloric acid, 30-39% of formaldehyde solution and 5-12.4% of dispersing agent viscosity improver.

The invention is further configured to: the organic solvent is one or more of dimethyl carbonate, diethyl carbonate, absolute ethyl alcohol and the like.

The invention is further configured to: the transfer paper comprises water-soluble vinylon fibers, polyvinyl alcohol and waterproof emulsion, wherein the content of the waterproof emulsion is 0.5-1.6%.

The invention is further configured to: the modification treatment comprises plant fiber modification treatment and animal fiber modification treatment, wherein the plant fiber modification treatment is carried out in a chemical modification mode, and the animal fiber modification treatment is carried out in an ultrasonic modification mode.

The invention is further configured to: the dispersant viscosity improver comprises a ferrous ion salt, and the content of the ferrous ion salt in the ink is more than 5 mg/L.

In conclusion, the invention has the following beneficial effects:

the ink that obtains through the ratio, thereby make it comparatively disperse when the stamp on the transfer paper, the effect of printing and dyeing is better, secondly the ink is not dissolved in aqueous, transfer paper for water-soluble paper has certain water-resistant effect after the ratio again, make the ink print when on transfer paper from this, transfer paper can not take place damaged problem, and after the rendition to the fabrics is accomplished, transfer paper can obtain fully dissolving in hot water, make can not remain the wastepaper of transfer paper on the fabrics, and simultaneously, transfer paper can form the chemical in aqueous, thereby make the fabrics soak wherein, fixed effect and subsequent cleaning performance to the fabrics effectively strengthen, make transfer paper can form the material and come to produce protection or other more excellent effects to the fabrics, make the resource obtain make full use of.
