Embodiment 1

[0032] Embodiment 1: a kind of knitting cloth printing and dyeing process with special effect, used gray cloth is 80% CVC knitted plain weave cloth, specifically comprises the following steps:

[0033] A. Pre-treatment gray cloth: treat the gray cloth with alkali, refining agent, hydrogen peroxide, and whitening agent, and dehydrate and shape it;

[0034] B. Burnt-out printing: prepare the hollow printing paste, and control its viscosity at 30000Pa.S. After the preparation is uniform, filter it with a 70-mesh screen, and print it with a rotary screen printing machine. The temperature of the machine printing drying room is 110 degrees;

[0035] C. Disperse reactive same paste printing: ①Prepare the flower paste: dissolve the disperse dye with water and add seaweed stock paste, then add the prepared anti-dyeing salt, finally add reactive dye and stir evenly with a high-speed mixer, ②Print on the machine: Print with a rotary screen printing machine, and the temperature of the dry...

Abstract

The invention relates to a knitted fabric printing and dyeing process with a special effect. A conventional CVC knitted fabric has the hazy three-dimensional printing effect by organically combining various processes together, such as active printing, dispersive printing, three-cedar sheet two-phase color fixation, and the like. The process is concretely divided into six steps of preprocessing blank fabric, burning-out printing, disperse/reactive printing in one paste, steaming, washing by water and molding, and the process is simple and is easy to operate; favorable physical and chemical indexes and color light reproducing performance are obtained through the two-phase color fixation process, thereby lower-end CVC burnt-out fabric becomes special style fabric with a high additional value. Accordingly, the invention has the characteristics of simple operation, high dye fixing rate, less pollution to environment, hazy three-dimensional special effect and favorable color light reproducing performance. The printing and dyeing process can be also used for a T/R product and a T/C product extended from the traditional CVC knitted fabric.

Description

technical field [0001] The invention relates to the technical field of knitted fabric printing and dyeing, in particular to a knitted fabric printing and dyeing process with special effects. Background technique [0002] With the improvement of people's living standards, the requirements for printing and dyeing of knitted fabrics are getting higher and higher, and personalized printing effects are becoming more and more popular. In addition to the long process route, high cost and difficult quality control, the existing conventional reactive dye printing and dyeing process also has the problem of serious environmental pollution caused by sewage discharge. With the continuous development of the printing and dyeing chemical industry, the environmental damage is increasing, and countries around the world, especially developed countries in Europe and the United States, advocate green textiles. China has also begun to pay more and more attention to the destruction of natural ecol...
