Embodiment 1

[0031] 1) Pretreatment: desizing:

[0032] Desizing formula (per liter): Premix M100 amylase 3.0g, non-ionic penetrant Goon106 0.5g, citric acid 0.6mL, softener H-413 0.5g.

[0033] Process conditions: pH value 6.0, liquor ratio 1:20, temperature 40-90°C, time 30 minutes; add citric acid to the desizing solution, adjust pH 6.0-7.0, so that Premix M100 amylase can exert its best performance.

[0034] 2) Prepare modified solution:

[0035] (1) Add 987.5 kg of deionized water to the reactor, start the stirring device, add 4 kg of cationic guar gum, stir well, add 0.5 kg of citric acid, heat up to 70-75 ° C for 20 minutes, and cool down after the reaction is completed At 30°C, a clear and transparent cationic guar gum thickened liquid with a viscosity of 2000-3000mPa.s is obtained.

[0036] (2) Add 5.5kg of dodecyltrimethylammonium chloride in the cationic guar gum thickening solution, stir evenly at normal temperature, then add 2.5kg of penetrant isomer thirteen in the reactor ...

Embodiment 2

[0046] 1) Pretreatment: desizing:

[0047]Desizing formula (per liter): 1.0 g of Premix M100 amylase, 2.5 g of commercially available Goon106 non-ionic penetrating agent, 1.5 mL of citric acid, and 2.0 g of commercially available H-413 softener.

[0048] Process conditions: pH value 7.0, bath ratio 1:15, temperature 40-90°C, time 30 minutes; add citric acid to the desizing solution, adjust pH 6.0-7.0, so that Premix M100 amylase can exert its best performance.

[0049] 2) Prepare modified solution:

[0050] (1) Add 910kg of deionized water into the reactor, start the stirring device, add 4kg of cationic guar gum, stir well, add 0.5kg of citric acid, heat up to 70-75°C for 20min, and cool down to At 30°C, a clear and transparent cationic guar gum thickened liquid with a viscosity of 3000mPa.s was obtained.

[0051] (2) add the dodecyltrimethylammonium chloride of 6kg in the described cationic guar gum thickener, stir under normal temperature, then add the commercially availab...

Embodiment 3

[0061] 1) Pretreatment: desizing:

[0062] Desizing formula (per liter): 2.0 g of Premix M100 amylase, 1.5 g of commercially available Goon106 non-ionic penetrating agent, 1 mL of citric acid, and 1.5 g of commercially available H-413 softener.

[0063] Process conditions: pH value 6.0-7.0, liquor ratio 1:15, temperature 40-90°C, time 30 minutes; add citric acid to the desizing solution, adjust pH 6.0-7.0, so that Premix M100 amylase can exert the best performance.

[0064] 2) Prepare modified solution:

[0065] (1) Add 1000 kg of deionized water to the reactor, start the stirring device, add 3 kg of cationic guar gum, stir well, add 0.6 kg of citric acid, heat up to 70-75 ° C for 20 minutes, and cool down to At 30°C, a clear and transparent cationic guar gum thickened liquid with a viscosity of 2500mPa.S was obtained.

[0066] (2) Add 0.6kg of lauryltrimethylammonium chloride in the cationic guar gum thickener, stir evenly at normal temperature, then add 3kg of penetrating ...

Abstract

The invention provides a novel environment-friendly dyeing method for jeans apparel. The novel environment-friendly dyeing method specifically comprises the following steps: (1) pretreatment: desizing; (2) preparation of a modified solution; (3) pad drying; (4) preparation of dye liquor; (5) dyeing and padding of jeans apparel; (6) finishing of the jeans apparel. According to the novel environment-friendly dyeing method for the jeans apparel, a sizing agent on the apparel is removed by desizing; by the adoption of cationic modification treatment, natural medicinal plant extract pigment dye for dyeing and jeans apparel finishing, satisfactory environment-friendly jeans cloth can be prepared, and the effect is obvious; the jeans apparel has excellent advantages of resistance to wet color, resistance to wash color, sun durability, long service life and the like, and is higher in practical value; the process is energy-saving and environment-friendly, and the jeans apparel does not contain formaldehyde.

Description

technical field [0001] The invention belongs to the technical field of denim and relates to a novel environmentally friendly dyeing method for denim garments. Background technique [0002] Denim fabrics and clothing are suitable for all ages and have strong versatility. They have become one of the fashions favored by domestic and foreign clothing consumers. With the rise of denim clothing, thousands of consumers in China can't let go of their nostalgia for her in "spring, summer, autumn and winter". [0003] Cotton and hemp fiber fabrics need to fully remove cellulose symbiosis before dyeing, minimize tension and friction during dyeing, and prevent deformation or fluff from affecting the quality of dyed products. The dyes used in cellulose fiber dyeing mainly include reactive dyes, direct dyes, sulfur dyes, insoluble azo dyes, vat dyes, oxidation dyes, etc. Reactive dyes are widely used due to their excellent dyeing properties, but the use of a large amount of inorganic sa...
