Problems solved by technology

Viscose fiber needs to be dyed under alkaline conditions, while nylon fiber needs to be dyed under neutral or weakly acidic conditions; at the same time, the staining of nylon by reactive dyes must be considered, which often makes the whole dyeing process complicated and lengthy. , and it is also difficult to balance the dyeing yield and color of the two fibers of viscose and nylon, especially when dyeing the different-sided woven fabrics composed of viscose and nylon fibers, the two fibers are dyed The balance defects in terms of color yield and hue will be more exposed
In addition, due to the temperature difference in the dyeing equipment, the above shortcomings are exposed and magnified.
[0003] Now some manufacturers are looking for a reactive dye that stains nylon fibers as much as possible to replace acid dyes to dye nylon to achieve the coloring effect on nylon, which also complicates the dyeing process
The most typical is that it is necessary to shut down and cut the plate during the dyeing process to evaluate the staining effect of reactive dyes on nylon and to check the color. If there is any difference, it is necessary to add color and repeat the dyeing process, which will result in low labor productivity and high energy consumption. Large, very inconsistent with the national goal and purpose of energy conservation and emission reduction

Embodiment 16

[0036] This embodiment is a composition of a reactive dye and an acid dye of the present invention applied to the cheese dyeing process of viscose / brocade 89 / 11,32s doubling yarn, the following is the operation process:

[0037] Firstly, put the bobbin yarn into each dyed bobbin and place it in the bobbin dyeing vat, then fill in the water, and correct the water level (water volume) to the specified bath ratio range (usually yarn weight: water weight = 1) when the pump is stopped. : 6), then run to drain after pretreatment such as degreasing or scouring, and set the automatically controlled dyeing process curve computer program while entering water to wash and cool the package to wait for dyeing, and enter the dyeing program.

[0038] Dyeing process:

[0039] Step 1: After entering the water to reach the water level required by the liquor ratio (reserve a part of clean water for the use of auxiliary agents in the subsequent process) to run, correct the head (pump force) and co...

Embodiment 17

[0049] The present embodiment is that the composition of a kind of reactive dyestuff of the present invention and acid dyestuff is applied to the dyeing process of sticky / brocade 70 / 30,40s Roman cloth, and the following is the operation process:

[0050] First, the dyeing vat is filled with water and then the cloth is fed, and the water level (water volume) is corrected to be within the specified liquor ratio range (usually cloth weight: water weight = 1:7) when the pump is stopped, and then it is run for pretreatment such as degreasing, and then While washing the cloth and waiting for dyeing, set the computer program of the automatically controlled dyeing process curve and enter the dyeing program.

[0051] Dyeing process:

[0052] The first step: After entering the water to the required water level of the bath ratio (reserve a part of clean water for the use of chemical additives in the subsequent process), run, and control the water temperature at 40°C.

[0053] Step 2: Re...

Embodiment 18

[0062] The present embodiment is that the composition of a kind of reactive dyestuff and acid dyestuff of the present invention is applied to the dyeing process of sticky / brocade 30 / 70,42s brocade wrapped sticky Roman cloth, and the following is the operation process:

[0063] First, the dyeing vat is filled with water and then the cloth is fed, and the water level (water volume) is corrected to be within the specified liquor ratio range (usually cloth weight: water weight = 1:7) when the pump is stopped, and then it is run for pretreatment such as degreasing, and then While washing the cloth and waiting for dyeing, set the automatically controlled computer dyeing process curve program and enter the dyeing program.

[0064] Dyeing process:

[0065] The first step: After entering the water to the required water level of the bath ratio (reserve a part of clean water for the use of chemical additives in the subsequent process), run, and control the water temperature at 40°C.

Abstract

The invention relates to a dye and an application thereof, in particular to reactive dye and acid dye composition and an application thereof. By means of combination of one or more different reactivedyes and acid dyes in a weight ratio of the reactive dyes to the acid dyes, full-bath and one-step fast dyeing production of textiles prepared from viscose and nylon in different content ratios of viscose to nylon can be realized very well, and requirements of the two fibers for color yield balance and hue flatness can be met to the maximum degree. The reactive dye and acid dye composition is black and commonly used with dyes in other colors. The reactive dye and acid dye composition is applied to fast dyeing of textiles such as viscose and nylon blended or interlaced knitted Roman cloth, foreign-fiber double-sided woven fabric, paralleled yarn, threads, stockings woven by the materials and the like.

Description

technical field [0001] The invention relates to a dye and its application, in particular to a composition of a reactive dye and an acid dye and its application. technical background [0002] At present, the dyeing of textiles composed of viscose / nylon fibers is completed through two dyeing processes. Viscose fiber needs to be dyed under alkaline conditions, while nylon fiber needs to be dyed under neutral or weakly acidic conditions; at the same time, the staining of nylon by reactive dyes must be considered, which often makes the whole dyeing process complicated and lengthy. , and it is also difficult to balance the dyeing yield and color of the two fibers of viscose and nylon, especially when dyeing the different-sided woven fabrics composed of viscose and nylon fibers, the two fibers are dyed The balance defects in terms of color yield and hue will be more exposed. In addition, due to the temperature difference in the dyeing equipment, the above shortcomings are exposed...
