Problems solved by technology

[0002] Batik is a traditional ethnic folk handicraft in Guizhou, with a single color tone and high fading rate
The use of high-temperature reactive dyes and low-temperature reactive dyes can increase the change of the color spectrum and make the color richer, but because the wax will melt when exposed to high temperatures, high-temperature reactive dyes cannot be used in batik
Therefore, since the 1980s, batik has generally used low-temperature reactive dyes in the dyeing process. Although the color is slightly richer than the traditional ones, the fading rate is still high, almost reaching 30-50%.

Embodiment 1

[0010] A method for modifying and fixing colors of reactive dyes, comprising the following steps:

[0011] (1) Preparation of dyeing solution: add 50 grams of water softener to 1000 grams of water at 28 ° C, then add 10 grams of low-temperature reactive dye X-3B Brilliant Red to dissolve, add 30 parts of urea after fully stirring, 20 grams of baking soda, 15 After 10 minutes, add 10 grams of catalyst triethylenediamine, raise the temperature to about 40°C, add 10 grams of soda ash after fully dissolving, and stir evenly;

[0012] (2) Put 500 grams of cotton fabric into dyeing and soaking for 30 minutes, take it out, soap boil, wash with water, and dry to obtain a bright red batik cotton fabric product.

[0013] After testing, the color fixation rate reaches more than 95%.

Embodiment 2

[0015] A method for modifying and fixing colors of reactive dyes, comprising the following steps:

[0016] (1) Preparation of dyeing solution: add 20 grams of water softener to 1000 grams of 25°C water, then add 5 grams of B-RV high-temperature active brilliant blue to dissolve, add 10 grams of urea after fully stirring, 5 grams of baking soda, 10 Minutes later, add 5 grams of catalyst triethylenediamine, raise the temperature to about 30°C, add 5 grams of soda ash after fully dissolving, and stir evenly;

[0017] (2) Put 300 grams of silk dyed material into dyeing and soak for 40 minutes, take it out, boil it with soap, wash it with water, and dry it to get the blue batik silk product with bright color and luster.

[0018] After testing, the color fixation rate reaches more than 95%.

Embodiment 3

[0020] A method for modifying and fixing colors of reactive dyes, comprising the following steps:

[0021] (1) Preparation of dyeing solution: Add 80 grams of water softener to 1000 grams of water at 30°C, then add 10 grams of reactive dye X-6G bright yellow to dissolve, add 20 grams of urea and 10 grams of baking soda after stirring well, after 20 minutes Add 10 grams of catalyst triethylenediamine, raise the temperature to about 35°C, add 10 grams of soda ash after fully dissolving, and stir evenly;

[0022] (2) Put 450 grams of silk burnt-out gauze to be dyed and soak for 30-40 minutes, take it out, boil with soap, wash with water, and dry to get bright yellow silk burnt-out gauze batik.

[0023] After testing, the color fixation rate reaches more than 95%.
