Problems solved by technology

[0002] Most of the traditional fabric dyeing adopts water dyeing process, and the water dyeing process needs to consume a lot of water resources. In recent years, some new anhydrous or less water dyeing technologies have been developed, such as the use of long-car dyeing machines to dye and fix colors. However, due to the reasons of production cost, product quality c...

Embodiment approach

[0025] Such as figure 1 Shown, the embodiment of a kind of fabric dyeing method of the present invention comprises the steps:

[0026] 1) Dyeing: pass the fabric 3 through the paddle 1 to complete the dye / pigment adsorption process;

[0027] 2) Color fixation by electromagnetic wave heating: put the colored fabric 3 in the step 1) into the electromagnetic wave heating device 2 to heat, and after a period of time, the dye / pigment diffusion and fixation process on the fabric 3 is completed.

[0028] After step 2) is completed, proceed to step 3), that is, turn on the electromagnetic wave heating device, take out the color-fixed fabric 3, and clean or soap the color-fixed fabric 3.

[0029] Further specifically, the dyeing in step 1) adopts immersion or sizing, and the specific steps include: configuring the required dyeing precursor or coating slurry according to the material of the fabric, in order to complete the uniform adhesion in the fabric, after dyeing Add corresponding...

Embodiment 1

[0035] Embodiment 1: pure cotton fabric is dyed

[0036] 1) Prepare the dyeing precursor solution. Since the dyeing of cotton needs to be in an alkaline environment and the color can be fixed under the action of salt, it is necessary to add an appropriate amount of salt and alkali when configuring the precursor solution.

[0037] 2) Dyeing: After the cotton fabric 3 to be dyed is flattened by the screw, it passes through the prepared dyeing precursor solution 4 at a constant speed, and is colored by the paddle 1 to complete the fabric coloring process.

[0038] 3) Color fixing process: the cotton fabric 3 after coloring by the padder is directly transported to the electromagnetic wave heating device 2, and the curing time is adjusted for 5 minutes to achieve the best curing effect.

Embodiment 2

[0039] Embodiment 2: dyeing polyester fabric

[0040]1) Dissolve an appropriate amount of disperse dye in water according to the process requirements, and add an appropriate amount of thickener in the water to increase the adsorption of the dye precursor solution to polyester yarn. Let the polyester fabric pass through the pre-prepared dyeing precursor solution at a constant speed, and then pass through the rollers of the padding car 1 and squeeze it through the extrusion wheel, and adjust the pressure of the extrusion wheel to 0.1MPa to dye;

[0041] 2) Send the dyed polyester fabric to the electromagnetic wave heating device 2, and adjust the color fixing time to 3 minutes.

Abstract

The invention provides a textile dyeing method and device. The fixation efficiency is high, and the even dyeing and fixation effect is good. The textile dyeing method comprises the following steps of1, dyeing, wherein textile is subjected to dye/pigment adsorption through a coloring system; 2, heating and fixation through electromagnetic waves, wherein the colored textile in the first step is putinto an electromagnetic wave heating device for heating, heating continues for a period of time, and the dye/pigment diffusion and fixation process for the textile is completed. According to the textile dyeing method, by adopting an electromagnetic wave heating mode, heating is conducted in the dyeing and solidification process of a long machine, through the heating mode, energy is saved, the temperature is increased and decreased quickly, cleanliness is achieved, the penetrability is high, heating is even, and the situation can be avoided that in the prior art, during dyeing and fixation ofthe long machine, due to uneven heating, dye migration of the cloth surface is caused, and accordingly color diffusion is caused.

Description

technical field [0001] The invention belongs to the technical field of dyeing, and in particular relates to a dyeing method and a dyeing device for dyed fabrics. Background technique [0002] Most of the traditional fabric dyeing adopts water dyeing process, and the water dyeing process needs to consume a lot of water resources. In recent years, some new anhydrous or less water dyeing technologies have been developed, such as the use of long-car dyeing machines to dye and fix colors. However, due to the reasons of production cost, product quality control and production efficiency, there is still no method that can completely replace water dyeing to be widely used. In addition, the traditional long-car dyeing machine uses electric heating or natural gas heating to fix the color, which has low heating efficiency, and the uneven heating causes the dye to migrate on the cloth surface, resulting in color phenomenon. [0003] In view of the above-mentioned problems existing in th...
