Embodiment 1

[0026] Example 1: A denim printing and dyeing process with printing and spraying effects. The gray fabric used is elastic denim knitted fabric, and the selected pattern is thin-neck letters filled with bottom scraping printing. Since the thin-neck letters require clear and fine, it is selected Pigment printing plus scraping printing, printing with sulfur dyes, has the following steps:

[0027] A. Pre-treatment gray cloth: Treat the gray cloth with alkali, refining agent and hydrogen peroxide, and dehydrate and shape it.

[0028] B. Printing: mixing paste ① pigment printing paste; ② sulfur dye printing paste. Scrape printing paint color paste first, then scrape printing sulfur dye printing color paste, flat screen printing, drying, the temperature of the machine printing drying room is 110 ℃.

[0029] C. Steaming: continuous steaming, temperature 102°C, time 6 minutes.

[0030] D. Water washing: use a continuous rope washing machine, use cold water for the first three steps, ...

Embodiment 2

[0040] A denim printing and dyeing process with printing and spraying effects. The gray fabric used is elastic denim. The pattern with more color registration is selected. In order not to affect the hand feeling and meet the requirements of rich colors, vat dyes are used for pattern printing. , the large scraping bottom is printed with sulfur dyes, which specifically includes the following steps:

[0041] A. Pre-treatment gray cloth: Treat the gray cloth with alkali, refining agent and hydrogen peroxide, and dehydrate and shape it.

[0042] B. Printing: Sizing ① vat dye printing paste; ② sulfur dye printing paste, flat screen printing, drying, machine printing drying room temperature is 115 ℃.

[0043] C. Steaming; the continuous steaming temperature is 100°C and the time is 8 minutes.

[0044] D, water washing; select continuous rope washing machine, the first three with cold water, the fourth with 75 ℃ hot water, the last two with cold water, centrifuge dehydration.

Abstract

The invention relates to a looped fabric printing and dyeing technology with special effects. A plurality of technologies of active printing, disperse printing and three-sheet two-phase dye fixation are combined organically, so as to endow a routine CVC looped fabric with a hazy stereo printing effect. The technology specifically comprises six steps of grey pre-treatment, burn out prints, disperse active one paste printing, ageing, washing and fixing. The technology is simple for operation; the two-phase dye fixation method renders the looped fabric good physicochemical indexes and good chromatic reproduction performance, so the low-end CVC burn-out becomes a special style fabric with high added value. Therefore, the invention has characteristics of simple operation, high dye fixation rate, little environmental pollution, hazy stereo special effect and good chromatic reproduction performance. The printing and dyeing technology can also be applied to epitaxial products of the traditional CVC looped fabrics like T / R and T / C.

Description

technical field [0001] The invention relates to the technical field of knitted fabric printing and dyeing, in particular to a denim printing and dyeing process with printing and spraying 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. Countries around the world, especially developed countries in Europe and the United States, advocate green textiles, and China has also begun to pay more and more attention to the destruction of natural ecology caused by pollution. The products among companies in the market are becoming more and more similar, and the ...
