Problems solved by technology

[0005] After adopting the above method, compared with the prior art, the present invention has the following significant advantages and beneficial effects: the present invention first carries out scouring or scouring, then dries, and then carries out cold pad-batch dyeing. The cotton-linen blended fabric is padded in the dyeing solution obtained by mixing the reactive dye and the alkaline agent mixture in a volume ratio of 4:1, and then stacked at a constant temperature to color the cotton-linen blended fabric. Under the joint action of the alkali agent mixed solution, it can effectively solve the problem that the three kinds of fibers have different colors and cannot be of the same color, and the finished product after the treatment of the invention has a bright color, so the invention has the ability to make the cotton-viscose linen blended fabric the same color The advantages of good effect and bright color

Embodiment 1

[0007] Embodiment one, the target color that cotton viscose linen blended fabric is dyed is buff camel, i.e. reactive dyestuff: RRN blue 0.61g / l, 3BS red 0.6g / l, 3RS yellow 1.58g / l; Alkaline agent mixed solution: 50g / l Soda Soda, 15g / l Liquid Soda.

[0008] Concrete steps are, 1, add liquid caustic soda 6g / l, hydrogen peroxide 3g / l, sodium peroxide 1.5g / l, refining agent 2g / l and chelating dispersant 2g / l to carry out boiling and bleaching to cotton viscose linen blended fabric, 2 1. Dry the boiled and bleached cotton-viscose-linen blended fabric, which can be dried with a setting machine. The drying temperature is controlled at 170-175 degrees Celsius, and the drying time is controlled at 20-25 minutes. 3. For the dried cotton Cold pad-batch dyeing of viscose-linen blended fabrics. During the dyeing process, the dyeing solution is obtained by mixing reactive dyes and alkaline agent mixtures at a volume ratio of 4:1. The ratio and liquid supply can be realized by proportional...

Embodiment 2

[0014] Embodiment two, the target color that cotton viscose linen blended fabric is dyed is black, i.e. reactive dyestuff: GWF black 55g / l, 3BS red 6.8g / l, 3RS yellow 13.5g / l; Alkaline agent mixed solution: 80g / l Soda alkali, 33g / l liquid alkali.

[0015] Concrete steps are, 1, add liquid caustic soda 6g / l, hydrogen peroxide 3g / l, sodium peroxide 1.5g / l, refining agent 2g / l and chelating dispersant 2g / l carry out boiling and bleaching to cotton viscose linen blended fabric, because It is a very light color, and it needs to be re-bleached once, that is, add soda ash 5g / l, hydrogen peroxide 2g / l, sodium peroxide 1g / l, refining agent 2g / l and chelating dispersant 2g / l, 2. The final cotton-viscose-linen blended fabric is dried. The drying can be dried with a setting machine. The drying temperature is controlled at 170-175 degrees Celsius, and the drying time is controlled at 20-25 minutes. 3. For the dried cotton-viscose-linen blended fabric Carry out cold pad-batch dyeing. Durin...

Embodiment 3

[0021] Embodiment three, the target color that the cotton viscose linen blended fabric is dyed is deep navy blue, i.e. reactive dyestuff: B black 35g / l, 3BS red 6g / l, 3RS yellow 10.45g / l; Alkaline agent mixed solution: 80g / l Paohua alkali, liquid alkali 33g / l.

[0022] The specific steps are as follows: 1. Add liquid caustic soda 6g / l, refining agent 2g / l and chelating dispersant 2g / l to scour the cotton-viscose linen blended fabric. Generally, scouring can be carried out for dark colors, which can be bleached or bleached. Can not be bleached, based on cost considerations, generally do not need to be bleached, such as black, dark brown, dark gray, etc. Control it at 170-175 degrees Celsius, and control the drying time at 20-25 minutes. 3. Carry out cold pad-batch dyeing on the dried cotton-viscose linen blended fabric. The ratio is 4:1, and the ratio and liquid supply can be realized by a proportional pump. The cotton and linen blended fabric is padded in the dyeing solution ...

Abstract

The invention discloses a dyeing method of a cotton viscose ramie blended fabric, which can enable the cotton viscose ramie blended fabric to obtain good homochromatic effect and beautiful color. The method comprises the following steps of: (1) first, boiling and blanching or boiling off the cotton viscose ramie blended fabric; (2) drying the boiled and blanched cotton viscose ramie blended fabric; (3) carrying out cold pad batch dyeing on the dried cotton viscose ramie blended fabric, wherein a dyeing liquid is obtained by mixing a reactive dye and an alkali auxiliary mixed solution according to a volume ratio of 4:1 in the dyeing process; padding the cotton viscose ramie blended fabric in the dyeing liquid for 3-6 seconds; winding the padded cotton viscose ramie blended fabric by using a winding frame; sealing and packaging the cotton viscose ramie blended fabric on the winding frame by using a sealing material after the winding is finished; and then placing the sealed and packaged cotton viscose ramie blended fabric in a constant temperature environment for 12-16 hours, wherein the temperature of the constant temperature environment is one of 25-30 DEG C; and keeping the winding frame to rotate at a constant speed, wherein the rotation speed is 4-6 rpm; and (4) taking the cotton viscose ramie blended fabric out of water and neutralizing the cotton viscose ramie blended fabric.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a method for dyeing cotton-viscose-linen blended fabrics. Background technique [0002] Cotton-viscose-linen blended fabric contains cotton, viscose, and linen fibers at the same time. Although they are all cellulose fibers, the three have different crystallinity and orientation in terms of structure, and it is difficult to achieve the same color during the dyeing process. At present, when dyeing with a conventional overflow dyeing machine, the effect of the same color is very unsatisfactory, and the color is dark. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above disadvantages of the prior art and provide a dyeing method of the cotton-viscose-linen blended fabric that can make the cotton-viscose-linen blended fabric have good same-color effect and bright color. [0004] The technical solution of...
