Problems solved by technology

[0005] The ability of carboxymethyl cellulose to ink is relatively poor, and it needs to be coated in a large amount. In addition, carboxymethyl cellulose in the transfer paper swells after absorbing water, making the paper surface elongate and arching, which is easy to rub against the printer. Nozzle, add a layer of "absorbing layer" to absorb moisture between the ink carrier layer and the base paper, although it can improve the drying speed of the inkjet sublimation transfer paper, but due to the sealing effect of the ink carrier layer, the drying speed will be improved limited capacity

Abstract

The invention discloses an easy-to-use ink-jet heat sublimation transfer paper. The paper comprises an ink holding layer, a paper fiber binding layer, a base paper layer and a back coating. The top layer of the transfer paper is the ink holding layer, the bottom layer of the transfer paper is the back coating and the paper fiber binding layer and the base paper layer are arranged between the ink holding layer and the back coating or a mixture layer of the paper fiber binding layer and the base paper layer is arranged between the ink holding layer and the back coating. The base paper layer is coated with the paper fiber binding layer through a coating machine or through a glue applicator in a paper machine in base paper layer preparation. Only one layer of the ink holding layer with very small thickness can prevent a dispersed dye from permeating into paper fibers and has an ink dye holding capacity which is 1.5-2.5 times that of carboxymethylcellulose and is more than 5 time that of polyvinyl alcohol so that a transfer rate is effectively improved. The coating has pore number greater than or equal to 20 per square millimeter so that an ink absorption capability is improved. Through use of the dried filling material in the transfer paper, a drying rate is fast in printing, a transfer paper shrinkage ratio is low, transfer paper water absorption arching-caused friction on a printer is avoided in ink-jet printing and the transfer paper can be used easily.

Description

technical field [0001] The invention belongs to the field of thermal sublimation transfer paper, in particular to an easy-to-use inkjet thermal sublimation transfer paper. Background technique [0002] Inkjet sublimation transfer paper is generally used for printing on polyester-containing fabrics or materials, using ink made of disperse dyes to print the image onto the inkjet sublimation transfer paper through an inkjet printer, and then print the printed surface with the substrate The transfer surface is pasted and heated to 170-230°C, the dye in the ink is sublimated into the transferred object by heat, and the transfer printing of graphics and text is realized. [0003] The emergence of inkjet sublimation transfer paper not only improves the printing precision, but more importantly, realizes the waterless printing and dyeing of textiles conveniently. The inkjet printer can directly print on the inkjet sublimation transfer paper under the control of the computer. It can ...
