Composite membrane quick-drying type dye-sublimation transfer printing digital paper

Abstract

The invention belongs to the field of transfer printed paper and particularly relates to composite membrane quick-drying type dye-sublimation transfer printing digital paper which comprises base material paper, a hydrophobic layer coated on the surface of the base material paper and an ink absorption layer coated on the surface of the hydrophobic layer, wherein a surface layer is coated on the upper surface of the ink absorption layer. The ink absorption layer is made of positive ion polyacrylamide cellulose interpenetrating polymer network resin. The surface layer is one or a combination of two of polyvinyl alcohol-vinyl acetate copolymer or polyvinyl butyral or polyvinyl alcohol. The hydrophobic layer is made of organosilicone modified acrylic resin. The composite membrane quick-drying type dye-sublimation transfer printing digital paper is provided with the surface layer which is one or a combination of two of polyvinyl alcohol-vinyl acetate copolymer or polyvinyl butyral or polyvinyl alcohol and can transfer a strong water permeation capability to the ink absorption layer on the condition of normal temperature. The number of intermolecular hydrogen bonds is reduced on the condition of high temperature, the surface layer can provide a large gap, dye molecules quickly and sufficiently sublimate in transfer printing digital paper coating materials, the transfer printing effect is ideal, and the composite membrane quick-drying dye-sublimation transfer printing digital paper has a wide application prospect.

Description

Technical field [0001] The invention belongs to transfer paper, and particularly relates to composite film quick-drying sublimation transfer digital paper. Background technique [0002] Printing and dyeing is the 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 a huge amount of waste water and environmental problems. In 2011, the national output of printed and dyed fabrics reached 59.3 billion meters, of which Zhejiang’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 fabrics reached more than 60 billion meters. With the advent of green chemistry and personalized digital era, digital thermal transfer technology is developing rapidly. 10-20% of printed and dyed fabrics in European and American countries are re...
