Problems solved by technology

[0005] Due to the different structures and properties of nylon fiber and wool fiber, the dyeing rate, dyeing amount and dyeing depth of acid dyes on the two fibers are also different, and the best process conditions for dyeing are also quite different. It is very difficult to dye the same color of fibers in the same tank and bath

Embodiment 1

[0031] Step 1: Pretreatment: Put the mixed fiber of nylon 56 and wool to be dyed into 50°C water, pre-wet for 10 minutes, and then drain.

[0032] Step 2: Dyeing with acid dye: based on the total amount of the dye solution, the formula of the dye solution is: 1% owf of tianlong yellow dye, 0.1g / L of sodium lauryl sulfate, and polyethylene glycol of 0.005g / L 4000, JFC 0.1g / L, pH=3 acetic acid / sodium acetate buffer solution. Take the dye liquid into a beaker, then add acetic acid / sodium acetate buffer solution with pH=3, sodium lauryl sulfate solid and other medicines and stir evenly, and finally put the pretreated nylon 56 and wool mixed fiber into the prepared In the dyeing liquor, the mass ratio of mixed fiber and dyeing liquor is 1:50. The temperature was raised to 100° C. at 1° C. / min, and then kept for 60 minutes.

[0033] Step 3: Color fixation: take out the dyed mixed fiber, squeeze out the water with 0.05MPa, then wash with cold water, and use Selefa N-HFG 3% owf to f...

Embodiment 2

[0038] Step 1: Pretreatment: Put the mixed fiber of nylon 56 and wool to be dyed into 50°C water, pre-wet for 20 minutes, and then drain.

[0039]Step 2: acid dyeing: based on the total amount of the dyeing solution, the formula of the dyeing solution is: 2% owf of sky dragon blue dye, 0.5g / L of sodium lauryl sulfate, polyethylene glycol of 0.001g / L 2000, JFC 0.1g / L, pH=4 acetic acid / sodium acetate buffer solution. Take the dye liquid into a beaker, then add acetic acid / sodium acetate buffer solution with pH=4, solid sodium lauryl sulfate and other medicines and stir evenly, and finally put the pretreated nylon 56 and wool mixed fiber into the prepared In the dyeing liquor, the mass ratio of mixed fiber and dyeing liquor is 1:40. The temperature was raised to 80° C. at 1° C. / min and then kept for 60 minutes.

[0040] Step 3: Color fixation: take out the dyed mixed fiber, squeeze out the water with 0.1MPa, and then wash with cold water, and use Selefa N-HFG 2% owf to fix the ...

Embodiment 3

[0045] Step 1: Pretreatment: Put the mixed fiber of nylon 56 and wool to be dyed into water at 40°C, pre-wet for 10 minutes, and then drain.

[0046] Step 2: Dyeing with acid dye: Based on the total amount of the dye solution, the formula of the dye solution is: 1% owf of Tianlong red dye, 2 g / L of sodium dodecylbenzene sulfonate, 0.1 g / L of polyethylene glycol Alcohol 400, JFC 0.1g / L, pH=4 acetic acid / sodium acetate buffer solution. Take the dye liquid into a beaker, then add acetic acid / sodium acetate buffer solution with pH=4, sodium dodecylbenzenesulfonate solid and other medicines and stir evenly, and finally put the pretreated nylon 56 and wool mixed loose fiber Into the prepared dye liquor, the mass ratio of mixed fiber and dye liquor is 1:50. The temperature was raised to 100° C. at 1° C. / min, and then kept for 60 minutes. After dyeing, rinse with water, wash in warm water, wash in cold water, and tumble dry.

[0047] Step 3: Color fixation: take out the mixed fiber...

Abstract

The invention relates to the field of textile dyeing and finishing, in particular to a one-bath dyeing solution and a dyeing method of nylon and wool mixed fibers. The technical scheme adopted in the invention is: carry out wetting pretreatment to two kinds of mixed fibers, then use acid dye to carry out one-time same-color dyeing in the same bath for the mixed fibers, and finally carry out color-fixing post-treatment. The invention puts two kinds of fibers in the same dyeing vat to dye with acid dyes, realizes the purpose of dyeing two kinds of fibers at the same time, changes the current traditional processing mode of separately dyeing two kinds of fibers, and greatly shortens the processing of traditional techniques The process reduces the production cost and has a significant effect of energy saving and emission reduction, and the same color of the two fibers is good. After the fiber is fixed, its soaping fastness can reach level 4.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a one-bath dyeing solution and a dyeing method of nylon and wool mixed fibers. Background technique [0002] With the development of textile industry technology and the improvement of people's consumption of textile and clothing, multi-component fiber textiles have risen strongly in the market, and are more and more favored by domestic and foreign consumers. Multi-component fiber blending is to mix fibers with different characteristics such as types, physical properties, functions, and shapes to weave clothing fabrics with functions, styles, and fabrics that single fiber materials do not have. At present, there are many kinds of multi-component fiber textiles on the market. Some popular blended products contain as few as 2 to 3 types of fibers, and as many as 4 to 6 types of fibers. These blended and interwoven textiles combine the properties of various fibers and off...
