Problems solved by technology

However, the inkjet printing technology currently used can only be directly printed on textile fabrics. If the inkjet printing method is used, it should be printed on the base paper to become transfer printing paper, and then transferred to the fabric. Many difficulties, unable to adapt to cold transfer printing process requirements
The main problem of inkjet printing transfer printing paper is that the existing inkjet printing ink and its inkjet printing process can not meet the requirements of transfer printing process, even if there is an inkjet printing ink suitable for transfer printing, it can be printed into transfer printing paper, but the transfer effect of such transfer printing paper is still very poor
In order to meet the practical requirements of inkjet printing transfer printing paper, its base paper also needs to be treated with a coating with an isolation effect, but the currently known isolation coating cannot achieve this purpose
Because be coated with the base paper of this present known isolation coating when printing, the pattern that ink-jet printing ink prints can not dry immediately, and spreads on paper surface, can't form practical transfer printing paper, or cause Transfer printing paper with severely deformed printing patterns

[0010] Base paper specification: 120g / m 2 base paper.

[0011] First use a 155-mesh anilox roller to roll-coat the base paper with an isolation layer, and the coating amount reaches 13-14g / m 2 . The isolation layer adopts fluorine-containing organic silicon polymer solution, and its concentration (mass) is 9-10%.

[0012] Finally, a 180-mesh anilox roller is used to coat the ink-receiving layer on the base paper coated with the isolation layer, and the coating amount reaches 15-17g / m 2 . The ink receiving layer used is as follows in terms of mass percentage: industrial grade xanthan gum is 0.4%, modified starch is 5%, carboxymethyl cellulose (CMC) is 10%, and water constitutes a 100% solution. The modified starch is a dry powder, which should be matured into a liquid after 5 hours in a reaction kett...

Embodiment 2

[0014] Base paper treatment coating for cold transfer printing paper, a base paper treatment coating for inkjet printing transfer printing paper suitable for synthetic fiber fabrics.

[0015] Base paper specification: 50g / m 2 base paper.

[0016] First use the scraper coating method to coat the base paper with an isolation layer, and the coating amount reaches 6-7g / m 2 . The isolation layer adopts fluorine-containing acrylate polymer solution, and its concentration (mass) is 5-6%.

[0017] Finally, the ink-receiving layer is coated on the base paper coated with the isolation layer by scraper coating, and the coating amount reaches 5-6g / m 2 . The used ink receiving layer is: 0.3% of industrial grade xanthan gum, 3% of compound starch for modified starch, 9% of carboxymethyl cellulose (CMC), and 100% solution with water. The composite starch is a dry powder, which should be aged in a reaction kettle with an aqueous solution at 65° C. for 5 hours before being used.

Embodiment 3

[0019] Base paper treatment coating for cold transfer printing paper, a base paper treatment coating for inkjet printing transfer printing paper suitable for viscose fabrics.

[0020] Base paper specification: 70g / m 2 base paper.

[0021] First use a 200-mesh anilox roller to roll-coat the base paper with an isolation layer, and the coating amount reaches 8-9g / m 2 . The isolation layer adopts fluorinated modified polysiloxane polymer solution, and its concentration (mass) is 7-8%.

[0022] Finally, a 200-mesh anilox roller is used to coat the ink-receiving layer on the base paper roller coated with the isolation layer, and the coating amount reaches 8-9g / m 2 . The used ink receiving layer is: 0.35% of industrial grade xanthan gum, 4% of modified starch, 9% of carboxymethyl cellulose (CMC), and 100% solution with water. The adhesive tape starch is a dry powder, which should be aged in a reaction kettle with an aqueous solution at 70°C for 5 hours before being used.

Abstract

The invention relates to a base paper treatment coating of sublistatic print paper for an inkjet printing. The base paper treatment coating comprises an isolation layer and an ink-bearing layer and is produced by the steps of firstly preparing the isolation layer of an organosilicon containing fluorin or an acrylate polymer containing fluorin with a coating weight of 6-15g / m<2>, then preparing the ink-bearing layer with a coating weight of 5-18g / m<2> and composed of xanthan gum, modified starch and carboxymethyl cellulose, and combining the two layers to obtain the final treatment coating. The base paper treatment coating of sublistatic print paper for the inkjet printing provided by the invention can be successfully peeled off and transfer-printed onto the fabrics due to the coated isolation layer, which causes a transient bonding of the sublistatic print paper on the base paper through a dye-based inkjet printing; and meantime, the base paper treatment coating of sublistatic print paper for inkjet printing provided by the invention solves the difficult problem of easy dispersing of dye-based ink patterns on the paper surface and can be successfully peeled off along with a part of ink-bearing layer and transfer-printed onto the fabrics when being closely transfer-printed with the fabrics to be printed due to the coated ink-bearing layer, which causes a transient bonding between the dye-based ink and the base paper coated with the isolation layer.

Description

technical field [0001] The invention relates to printing and dyeing engineering in the textile industry, in particular to a base paper treatment coating for ink-jet printing transfer printing paper. According to the process requirements of transfer printing, the base paper of inkjet printing transfer printing paper must be pretreated first, and then coated with two treatment layers that act as isolation and ink bearing, so that digital inkjet printers can print conventional transfer printing Paper, and can transfer the dye ink pattern on the transfer printing paper to various textile fabrics. Background technique [0002] Transfer printing with transfer printing paper has become a new method for daily industrial decoration and textile printing. It is to print the pattern or text to be printed on special paper with suitable dye ink by printing method Transfer printing paper, and then close the dyed side of the transfer printing paper to the printed fabric, and the dye ink is...
