Cloth printing method

Abstract

The invention provides a cloth printing method and belongs to printing methods. The cloth printing method comprises steps of cloth selecting, size blending, cloth sizing, cloth printing, ageing, clothcooling, cloth washing and setting a finished product. The method comprises the following steps: (1) selecting cloth, namely selecting cotton cloth; (2) carrying out size blending, namely adding 4-6parts of carboxymethylcellulose, 2-4 parts of polydimethylsiloxane, 12-16 parts of methylene-bisacrylamide, 6-10 parts of itaconic acid, 0.4-0.6 parts of sodium persulfate and 60-80 parts of water into a container, transferring the container into a digital display speed-measuring constant-temperature magnetic stirrer, stirring and reacting under conditions of a temperature of 65-75 DEG C and a rotation speed of 70-90 revolutions per minute for 80-100 minutes, taking out the container, naturally cooling materials in the container to a room temperature, and filling to obtain a printing pulp material; and (3) carrying out cloth sizing, namely spreading the selected cloth, and uniformly coating the printing pulp material onto the positive and reverse sides of the cloth. According to the printing method disclosed by the invention, the finished cloth is washable, does not fade, and is bright in printing color.

Description

technical field [0001] The invention relates to a printing method, in particular to a cloth printing method. Background technique [0002] Currently, the process of patterning dyes or paints on fabrics is called fabric printing. Printing is partial dyeing, requiring a certain color fastness. One of the important ways of fabric pattern decoration. After printing, it can improve the aesthetics of textiles and increase the color of textiles. In recent years, printing paste has been more and more respected in the printing industry, thanks to its own diversity can change a variety of printing effects, simple and convenient operation, easy storage, environmental protection and pollution-free and other advantages. The printing pastes currently on the market are all emulsified thickening systems, which are composed of emulsified paste, sodium alginate, etc., which are made by adding ammonium sulfate, adhesives, and paint color pastes.

Problems solved by technology

The printing pastes currently on the market are all emulsified thickening systems, which are composed of emulsified paste, sodium alginate, etc., which are made by adding ammonium sulfate, adhesives, and paint color pastes. There are several disadvantages in the process of use: 1. The printing paste has poor stability and is easy to become thinner and stratified; the other is poor water holding capacity and easy to seep

Moreover, the existing printing paste is not firm, and it is easy to dissolve and disperse into the medium after encountering water and other substances, causing fading, which in turn affects the aesthetics of textiles to a large extent, so it is necessary to solve the problem of color fading and deflowering of printed cloth
