Embodiment 1

[0021] This embodiment relates to a printing and dyeing method for controlling the phenomenon of reactive brilliant blue dyeing, and the method comprises the following steps:

[0022] Step 1, taking the fabric and performing pretreatment; the pretreatment includes the following steps: scouring and bleaching the fabric under alkaline conditions, and then adjusting the pH value of the fabric to be neutral;

[0023] Step 2, adjust the temperature in the constant temperature dyeing vat to 30°C; then add the amount of alkali to 0.6g / L; add reactive brilliant blue after 10 minutes; then raise the temperature to 60°C, put the fabric into the dyeing vat, and dip dye for 20 minutes; then Then heat up to 80°C and dip for 20 minutes; then cool down to 75°C and keep warm for 10 minutes;

[0024] Step 3: Take out the dyed fabric, wash it with water, fix the color and dry it.

[0025] Implementation effect: adopting the dyeing method of the present invention can effectively reduce the sens...

Abstract

The invention relates to a printing and dyeing method for controlling reactive brilliant blue staining dyeing-defect phenomena. The method includes the following steps that step one, a fabric is taken and undergoes pretreatment; step two, the temperature in a constant-temperature dye vat is adjusted to be 30-38 DEG C and then alkali is added; reactive brilliant blue is added after 10-15 minutes; heating is performed to reach the temperature of 60-70 DEG C, and the fabric is put into the dye vat to undergo dip dyeing for 20-30 minutes; then, heating is performed to reach the temperature of 80-90 DEG C, and dip dyeing is performed for 20-30 minutes; cooling is performed to reach the temperature of 75-85 DEG C, and heat preservation is performed for 10-20 minutes; step three, the dip-dyed fabric is taken out to undergo washing, color fixation and drying. By the adoption of the printing and dyeing method, the sensitivity of the reactive brilliant blue to the dyeing conditions can be effectively reduced, the dyeing-defect problems easily produced by using the reactive brilliant blue can be effective solved, the dyeing effect of the reactive brilliant blue and the production efficiency are greatly improved, and the printing and dyeing method has very good practical production and application value.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing, and in particular relates to a printing and dyeing method for controlling the discoloration phenomenon of reactive brilliant blue dyeing. Background technique [0002] There are many reasons for the appearance of colored flowers, such as uneven treatment of the base fabric, improper capillary effect, improper use and configuration of reactive dyes, and the temperature during dyeing. and time control, as well as humidity and other control factors; Reactive Brilliant Blue is a medium-temperature reactive dye with a vinylsulfone structure, and the color fastness of dyed cotton fabrics is excellent, especially the light fastness is better; Reactive Brilliant Blue is a medium-temperature blue Occupies a unique position in reactive dyes; the dyeing stability of reactive brilliant blue is extremely sensitive to process conditions, and various problems will occur, which will bring great troubles to...
