Digital printing and dyeing paper used for cotton fabrics, and preparation method thereof

Abstract

The invention discloses a digital printing and dyeing paper used for cotton fabrics. The digital printing and dyeing paper comprises a substrate and a functional material coat covered on the substrate; the functional material coat comprises a printing system, a catalytic system and an auxiliary system; the printing system comprises one or more selected from water-soluble polymers and amphiphilic polymers; the catalytic system comprises one or more selected from amide compounds, amine compounds, water-soluble metal hydroxides, weak acid salts of alkali metals, and weak acid salts of alkaline earth metals; and the auxiliary system comprises a coating agent, an antifoaming agent, an adsorbent and an antiseptic. There is no need to preprocess the fabrics when the digital printing and dyeing paper is used to chemically print and dye various cotton fabrics, so the technological cost is substantially saved; and printed and dyed products obtained through using the digital printing and dyeing paper have the advantages of brilliant color, excellent color fastness, good permeability and comfortableness, maintenance of the original application performances of the cotton fabrics, and substantial effect.

Description

technical field [0001] The invention relates to a digital printing and dyeing paper used for cotton-containing fabrics and a preparation method thereof. The digital printing and dyeing of cotton-containing fabrics belongs to the field of printing and dyeing. Background technique [0002] The energy-saving and environment-friendly green printing and dyeing process is being strongly supported and promoted by the national or local government to gradually replace the traditional printing and dyeing process. The current digital printing and dyeing process can be divided into the following two types according to the principle: (1) physical printing and dyeing method in which pigment molecules and fabrics are combined through physical bonding (such as patents: 201010119584.6, 201010109026.1), (2) pigment molecules and fabrics Chemical printing and dyeing method combined with chemical bonds (such as patents: 200710040431.0, 200810201472.8). For the physical printing and dyeing meth...

Problems solved by technology

[0004] However, the existing digital chemical printing and dyeing technology requires pre-treatment of fabrics (such as patent: 200710037612.8). Pre-treatment not only increases the cost of the process, but also leads to a series of problems, such as difficult control of process factors and a significant decrease in the stability of product dyeing quality , The slurry substance contained in the product is difficult to remove, the fabric fiber degeneration and other problems, which affect the mass promotion of new technology
