Embodiment 1

[0019] Take a piece of indigo denim and soak it in the solution for enzyme desizing and anti-seepage pretreatment. The function of enzyme desizing is to remove the size on the fabric fibers, which is conducive to better contact and adhesion of dyes to the fibers on the fabric. In conclusion, the role of anti-seepage is to prevent the ink from spreading to the surroundings during printing, resulting in blurred patterns. The technical formula of the solution is to add 4g of amylase, 5g of salt, 1g of sodium alginate, 2g of sodium bicarbonate, and 1.5g of urea per liter of water. Treatment conditions: the temperature is 55°C; then dry at 90°C; in the presence of vinylsulfone type epoxy resin-based polymer reactive dye 5%; surfactant OP-100.6%; humectant PEG 5%; deionized water 89.4%, after preparing according to the above formula, add PH value buffer solution to adjust the PH value to 8, print under the printer of the prepared ink; then through a post-treatment of spraying hot al...

Embodiment 2

[0026] Take a piece of indigo denim and soak it in the solution for enzyme desizing and anti-seepage pretreatment. The technical formula of the solution is to add: 6g of amylase, 7g of salt, 2g of sodium alginate, 5g of sodium bicarbonate, 4g of urea, after preparing according to the above formula, add pH value buffer to adjust the pH value to 6, treatment conditions: temperature is 60°C; then dry at 100°C; Dye 10%; Surfactant OP-100.7%; Humectant PEG 7%; Deionized water 82.3%, after preparing according to the above formula, add pH value buffer solution to adjust the pH value to 8, and print on the printer of the prepared ink; After a post-treatment of spraying hot alkali, the concentration of alkali solution is 15g of alkali per liter of water, and the temperature is 75°C; it is dried at 100°C, washed with water, and then dried at 100°C.

Embodiment 3

[0033] Take a piece of indigo denim and soak it in the solution for enzyme desizing and anti-seepage pretreatment. The technical formula of the solution is to add per liter of water: 8g of amylase, 9g of salt, 4g of sodium alginate, 7g of sodium bicarbonate, urea 6g, after preparing according to the above formula, add pH buffer solution to adjust the pH value to 6.5, conditions: the temperature is 65°C; then dry at 110°C; %; Surfactant OP-100.9%; Moisturizing agent PEG 9%; Deionized water 75.1%, after preparing according to the above formula, add pH value buffer solution to adjust the pH value to 8, and print under the printer of the prepared ink; A post-treatment of hot alkali spraying, wherein the concentration of alkali solution is 18g of alkali per liter of water, and the temperature is 78°C; it is dried at 110°C, washed with water, and then dried at 110°C.

Abstract

The invention relates to reactive ink for printing and dyeing, containing the following components of 5%-20% of vinyl-sulfone epoxy resin-based high-polymer reactive dyes, 0.5%-1% of surface active agents OP-10, 5%-10% of propylene glycol PEG and 69%-89.5% of deionized water, and the PH value of the high-polymer reactive ink for printing and dyeing is 7-9 through adding a PH-value buffer solution after mixing the components. The invention also relates to a method for carrying out jet printing on a denim fabric by adopting the ink, comprising the following steps of: pretreating and drying the denim fabric, then carrying out jet printing by adopting the high-polymer reactive ink for printing and dyeing, after treating and drying the denim fabric, and finally washing and drying the denim fabric. After being used, the reactive ink for printing and dyeing and the method for carrying out jet printing on the denim fabric have the advantages of environmental protection and energy saving; the printed denim fabric has the advantages of high washing-resistant color fastness and wear-resistant color fastness and favorable hand feeling; and meanwhile, the quality level and the additional value of denim garment are enhanced.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an active ink for printing and dyeing and a method for inkjet printing of denim fabrics using the ink. Background technique [0002] The development prospect of the denim industry is very broad. At present, the focus is on the development of new fibers and functional denim fabrics, which can further meet the needs of denim clothing development. Although the current competitiveness of enterprises is constantly increasing, the domestic denim fabrics are still mainly low-end products, and the proportion of high-end denim fabrics is not high. Traditional denim fabrics can no longer meet the needs of the market. Vigorously developing high value-added products is a key issue faced by denim fabric and garment manufacturers. [0003] The innovation and application of finishing technology has become a necessary means to improve product quality and added value. Denim ...
