Reactive-dye wet-transfer printing technology of pure-cotton fabric

Abstract

The invention discloses a reactive-dye wet-transfer printing technology of pure-cotton fabric. The reactive-dye wet-transfer printing technology adopts the technical process as follows: conducting alkali rolling on the fabric, rolling and transferring, piling and performing color fixing, and washing and drying; a formula of an alkali solution is as follows: 15g / L of a caustic soda solution and 31g / L of sodium silicate solution; transfer printing conditions are as follows: the alkali rolling liquid rate is 70-80% and the transfer printing pressure is 0.2-0.4MPa; printing of transfer printing paper adopts the technical process as follows: concocting a color paste, printing transfer paper and airing; a formula of the color paste is as follows: 0.5-3.0% of reactive dye, 3-15% of urea, 25-40% of modified starchRX60+ emulsified paste and the balance of water. Transfer printing adopts a method of printing the transfer printing paper, is rich and colorful and multi-layered in pattern, convenient and free in pattern design and strong in expressive ability, can print the pattern with vivid pattern shape and strong artistry, is simple in equipment and convenient in management, and can reduce pollution to the environment.

Description

[0001] technical field [0002] The invention belongs to transfer printing, and in particular relates to wet transfer printing of pure cotton fabric with reactive dyes. [0003] Background technique [0004] As a relatively new printing method, transfer printing has changed the traditional printing process in the past. It uses suitable dyes or paints to print the required patterns on special paper to make transfer printing paper. Then the pattern on the transfer paper is transferred to the fabric by heat and pressure or pressure and solvent. However, most of the disperse dyes are transferred to polyester textiles by sublimation. However, synthetic fibers, like other man-made chemicals, have caused a lot of trouble to humans. [0005] Contents of the invention [0006] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a wet transfer printing of reactive dyes for pure cotton fabrics to reduce environmental...
