Problems solved by technology

[0004] 2. Some finished fabrics can only be made by mixing dyes. The compatibility of dyes and the timing of adding salt and alkali will directly affect the hue reproducibility of small sample dithering and large sample dyeing. In the traditional small sample dithering process , it is necessary to add dye first, and the fabric is dyed in the dyeing solution by adding salt and alkali in stages. Therefore, it is necessary to pursue the consistency of the dithering process of the small sample and the dyeing process of the large sample, which can only achieve twice the result with half the effort.

Embodiment 1

[0038] Such as figure 1 As shown, the sample dithering process of cotton knitted fabrics in this embodiment is dyed for high-temperature reactive dyes, and the process flow is as follows:

[0039] Small sample soaking treatment steps: Accurately weigh several pieces of dry pre-treated cotton knitted fabrics, put the cotton knitted fabrics into a stainless steel cup with a bath ratio of 1:10 for soaking, and then place the stainless steel cup in an induction cooker Heat to 80°C, rinse the cotton knitted fabric with cold water after 10 minutes, wring it out and spread it flat to make the humidity consistent.

[0040] Dyeing solution configuration steps: use high-temperature reactive dyes to prepare a high-temperature dyeing solution with a specified concentration, and the specific steps are as follows:

[0041] (1) Accurately weigh the high-temperature reactive dye according to the prescription and add it to a 50ml beaker, dissolve the dye with warm water at 40°C and stir well ...

Embodiment 2

[0052] Such as figure 2 As shown, the sample dithering process of cotton knitted fabrics in this embodiment is aimed at dyeing neutral color with medium-temperature reactive dyes, and the process flow is as follows:

[0053] Small sample soaking treatment steps: Accurately weigh several pieces of dry pre-treated cotton knitted fabrics, put the cotton knitted fabrics into a stainless steel cup with a bath ratio of 1:10 for soaking, and then place the stainless steel cup in an induction cooker Heat to 80°C, rinse the cotton knitted fabric with cold water after 10 minutes, wring it out and spread it flat to make the humidity consistent.

[0054] Dye liquor configuration steps: Use medium-temperature reactive dyes to prepare a neutral dye liquor with a specified concentration. The specific steps are as follows:

[0055] (1) Accurately weigh the medium-temperature reactive dye according to the prescription and add it to a 50ml beaker, dissolve the dye with warm water at 50°C and st...

Embodiment 3

[0066] The small sample dithering process of cotton knitted fabrics in this embodiment is aimed at dyeing dark colors with medium-temperature reactive dyes. A dark dye solution with a specified concentration, and the dark dye solution is then subjected to an auxiliary agent addition step and a dyeing treatment step.

Abstract

The invention discloses a hand sample color imitation process for cotton knitted fabric. The hand sample color imitation process is mainly designed to overcome the defect that the reproducibility of the color phase of a hand sample and the color phase of a bulk sample is low due to a traditional hand sample dyeing process. The hand sample color imitation process for the cotton knitted fabric comprises the steps of hand sample soaking treatment, dyeing liquid preparation, additive adding and dyeing treatment. In the step of additive adding, anhydrous sodium sulphate of a first preset amount and sodium carbonate of a second preset amount are added to high-temperature dye liquor or neutral color dye liquor or dark color dye liquor at one time, or the anhydrous sodium sulphate of the first preset amount and the sodium carbonate one third of the second preset amount are added to light color dye liquor for the first time. In the step of dyeing treatment of the light color dye liquor, when the dye liquor is 35 DEG C to 40 DEG C, the sodium carbonate of two thirds of the second preset amount is added for the second time. The reproducibility of the dyeing hand sample and bulk sample of the cotton knitted fabric can be effectively improved, the one-time success rate of bulk sample dyeing is improved, and production cost is lowered.

Description

technical field [0001] The invention relates to a sample dithering process of cotton knitted fabrics. Background technique [0002] There are many factors that affect the reproducibility of fabric dithering and large samples, such as liquor ratio, time, temperature, dyeing materials, fabric pretreatment, dyeing process, etc. Many textile enterprises in our country are striving to eliminate the influence of the above-mentioned factors, especially emphasizing the consistency of the dithering process of the fabric sample and the large sample dyeing process. Especially in the dithering of reactive dyes of cotton knitted fabrics, there is a phenomenon that the reproducibility of the hue of the small sample dithering and the hue of the large sample dyeing is less than 70%. The reasons for this result are: [0003] 1. The dyeing process of the small sample dithering equipment is different from that of the large sample dyeing equipment. The small sample dithering is that the dye li...
