Thermal sublimation and transfer digital paper with high ink suction amount

Abstract

The invention belongs to the field of transfer paper and particularly relates to a piece of thermal sublimation and transfer digital paper with high ink suction amount. The thermal sublimation and transfer digital paper comprises a piece of substrate paper, a hydrophobic layer coated on the surface of the substrate paper, an ink suction layer coated on the surface of the hydrophobic layer, and a surface layer on the upper surface of the ink suction layer. In terms of calculation by weight, the ink suction layer is a composite material of an inorganic material and cationic polyacrylamide cellulose interpenetrating network resin, wherein the inorganic material is one or a combination of two of porous silicon dioxide or porous calcium carbonate or porous alumina. The hydrophobic layer is organosilicone modified acrylic resin. According to the thermal sublimation and transfer digital paper, the composition material which is one or the combination of two of the porous silicon dioxide or the porous calcium carbonate or the porous alumina is added into the ink suction layer, the solid porous structure can rapidly and sufficiently absorb dye molecules, and the ink suction amount of the thermal sublimation and transfer digital paper is remarkably increased.

Description

technical field [0001] The invention belongs to transfer printing paper, in particular to thermal sublimation transfer printing digital paper with high ink absorption. Background technique [0002] Printing and dyeing is a general term for dyeing, printing, finishing, washing and other processing methods. my country's printing and dyeing has an important impact on the global clothing industry, but it also produces huge amounts of wastewater and environmental problems. In 2011, the national output of printed and dyed cloth reached 59.3 billion meters, of which Zhejiang Province's output reached 36.2 billion meters, accounting for 61.1% of the national total; followed by Guangdong, Jiangsu and Fujian. In 2012, my country's production of printed and dyed cloth reached more than 60 billion meters. With the advent of green chemistry and personalized digital age, digital thermal transfer printing technology is developing rapidly. 10-20% of the printing and dyeing fabrics in Euro...

Problems solved by technology

[0004] However, in the prior art, one-layer coating is usually used to produce sublimation transfer printing digital coated paper, and the molecules are saturated with each other, resulting in a relatively small amount of ink absorption. There are also reports of two-layer coating but lack of function design

Some sublimation transfer digital coated papers contain glycerin. During the high-temperature transfer process, glycerin is transferred to the surface of chemical fiber cloth, leather, and ceramics along with the dye, which will affect the quality of patterns and images.

In addition, the current sublimation transfer printing digital coated paper technology still has disadvantages such as low ink absorption, slow drying speed, low reuse rate, and dye molecules penetrating into the substrate paper to affect the dye transfer rate.
