Problems solved by technology

[0002] With the continuous development of digital and imitation digital technology, the aesthetics of digital technology printing products are more and more popular among people. However, the old printing technology has little operability, and the digital printing and imitation digital printing process is single and easy to be copied. The environmental pollution is relatively large. In order to rejuvenate the knitted fabric hanging process, it is necessary to introduce digital printing technology to make it have the effect of digital printing and protect the intellectual property rights and economic interests of the manufacturer. Therefore, it is necessary to develop a new printing and dyeing process.

Embodiment 1

[0025] The present invention is a hanging printing burnt-out process with digital printing effect, the gray cloth used is nylon-cotton knitted burnt-out fabric, which specifically comprises the following steps in sequence:

[0026] a) Pre-treatment gray cloth: pre-treat the gray cloth with sodium hydroxide, non-phosphorus multifunctional scouring agent and hydrogen peroxide, and dehydrate and shape it;

[0027] b) Bottom dyeing: Double dyeing is used to dye the bottom, the base nylon is dyed with acid dyes, and the surface is dyed with removable reactive dyes;

[0028] c) Sketching and netting: use eight-color separation software to draw drafts according to the hanging printing process, and use 100 mesh screens to make nets;

[0029] d) Preparation of hanging printing paste: melt the vat dye with glycerin and add it to the homemade hanging white puree, and use a high-speed mixer to get the vat dye hanging printing paste. According to the drawing requirements, each of the four...

Abstract

The invention discloses a discharge printing and burnt-out technology having a digital printing effect. The technology orderly comprises the following steps: pre-treating gray cloth, double dyeing base cloth, drawing and making nets by utilizing an eight-color separation technology, dip dyeing and synchronously printing, ageing, water washing, and forming. Through organic combination of a plurality of technologies of eight-color separation digital imitation printing, reduction discharge printing, and burnt-out printing, the conventional cotton knitted cloth is enabled to have a hazy and stereo digital printing effect, the base color is uniform and penetrable, and the technology is easy to operate; because of adoption of eight-color separation digital imitation printing technology, the fabrics are enabled to have a digital printing effect, thus the grade of the products is improved, besides the products are hard to replicate; through the technologies of bottom dyeing and reduction discharge printing and burnt-out printing, the fabrics are enabled to have good physical and chemical indexes, so additional value of the products is increased; furthermore, the digital printing and digital imitation printing cannot carry out discharge printing technology production, the blank of the digital printing technology is fulfilled, the technology has a high technical content and little pollution to the environment, and the product has a novel, hazy and stereo effect.
