Embodiment 1

[0038] T / C 65 / 35 20×20 108×58 150cm Gauze jungle camouflage printed cloth

[0039] 1. Process flow

[0040] Singeing—deboiling and bleaching—mercerizing—setting—dyeing base color—printing—baking—rapid steaming—washing—finishing—finished product

[0041] 2. Process conditions

[0042] (1) The process conditions of the pre-treatment process are the same as those of the traditional printing process. The wool effect of the fabric is required to be 8-10cm / 30min, the whiteness consistency is good, the pH value of the cloth surface is 7-8 and uniform, and the cloth surface should be flat and the width is consistent after the shaping process. The ground color usually uses the dispersion / reduction process, which requires the color to be consistent, fully washed, and the cloth to be rolled. The pre-treatment requires the consistency of the indicators and the cloth surface is clean and free of fluff, so as to prevent uneven dyeing and blockage of the flower net to cause missing printi...

Embodiment 2

[0059] According to embodiment 1 process condition, adjust the pulping slurry formula as follows:

[0060] The composition of the slurry is that each liter of slurry contains:

[0061] Disperse dye 10g

[0062] Reactive dye 5g

[0063] Raw paste 750g

[0064] Urea 40g.

Embodiment 3

[0066] According to embodiment 1 process condition, adjust the pulping slurry formula as follows:

[0067] The composition of the slurry is that each liter of slurry contains:

[0068] Disperse dye 50g

[0069] Reactive dye 30g

[0070] Raw paste 750g

[0071] Urea 40g.

[0072] By the technique of embodiment 1-3, the main index detection of finished product all can be higher than following standard:

[0073]

[0074] Moreover, the steam consumption of the steamer during the processing is 250-300kg / hour, which greatly reduces the steam consumption.

[0075] In addition, the storage time of the remaining slurry can be extended to one week, and the finished products used in the rapid steaming process are not inferior to the traditional steaming process in terms of pattern fineness, color brightness, color yield, color fastness, and hand feeling. .

Abstract

The invention belongs to the field of textiles printing processing, and relates to a fast ageing process of T / C fabric dispersion / active camouflage prints. The printing process comprises the followingsteps: mixing slurry by adopting the following components for each liter of slurry: dispersion dye X, active dye Y, 750g of original paste, and 40g of urea; roasting: performing the roasting at the temperature of 200 to 205 DEG C and at a speed of 45 to 50 meters per minute; ageing at the temperature of 125 to 130 DEG C and at the speed of 25 to 30 meters per minute, wherein a color fixing solution is applied in a manner of applying the solution to a single front surface when in ageing, and the color fixing solution comprises the following components: 12.5g of NaOH, 150g of Na2CO3, 150g of Na2SO4, and 15g of starch; and other conditions are same with the traditional process. The process stability is improved, and the color difference is reduced. The storage time of the remaining slurry isprolonged. The indexes of a finished product such as pattern exquisiteness, color brightness, color obtaining degree, color fastness, hand feeling and the like are not lower than that of the traditional ageing process.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing processing, in particular to a T / C fabric camouflage printing process. Background technique [0002] The printing of T / C blended fabrics usually adopts the dispersion / reactive two-phase printing process, in which the color fixing of reactive dyes needs to be steamed on a steamer, and a large amount of steam is consumed in the process. Alkali agent is necessary in the color fixing conditions of dyes, which causes the disperse dyes in the same bath to be baked and fixed under alkaline conditions, which will cause unstable situations such as lightening and discoloration of dyes. Due to the influence of alkaline agents, there are still phenomena such as hydrolysis failure in the long-term storage of the color paste, which makes the process control more difficult. And as far as the process is concerned, soaping is generally required after steaming, and then washed with water. The process is ...
