Embodiment 1

[0024] Embodiment 1: ultrasonic process

[0025] Soak the hemp fiber in 10wt% sodium hydroxide solution for 1 hour at room temperature. After taking it out, wash it with water and dry it for later use.

[0026] Weigh 0.02g of Reactive Brilliant Blue KN-R and dissolve it in 50mL of water, soak the pre-treated hemp fiber in the dye solution at 50°C, add 2g of sodium chloride, treat it under ultrasonic conditions for 30min, and then 90 ℃, add 1g of sodium carbonate, and fix the color at this temperature for 10 minutes. After dyeing, take out the hemp fiber, wash with soap, water, and dry.

Embodiment 2

[0027] Embodiment 2: ultrasonic process

[0028] Soak the hemp fiber in 10wt% sodium hydroxide solution for 1 hour at room temperature. After taking it out, wash it with water and dry it for later use.

[0029] Weigh 0.02g of Reactive Brilliant Blue KN-R and dissolve it in 50mL of water, soak the pre-treated hemp fiber in the dye solution at 50°C, add 2g of sodium chloride, treat it under ultrasonic conditions for 30min, and then 90 ℃, add 1g of sodium carbonate, and fix the color at this temperature for 30 minutes. After dyeing, take out the hemp fiber, wash with soap, water, and dry.

Embodiment 3

[0030] Embodiment 3: ultrasonic process

Abstract

The invention provides application of an ultrasonic technology to hemp fiber dyeing. The application includes the specific steps that 1, firstly reactive dye are dissolved in water for being prepared into dye liquor, textile to be processed is dipped into the dye liquor, neutral salt with the final concentration being 0-100 g / L is added, and ultrasonic treatment is conducted for 10-60 minutes at the temperature of 30-60 DEG C; 2, the temperature is raised to 90 DEG C under the state that no ultrasonic exists, alkaline agents with the final concentration being 10-50g / L is added, and color fixing is conducted for 30-60 minutes under the condition; 3, the textile is taken out after dyeing, washed with soap, washed with water and dried; the concentration of the reactive dyes is 1-5 o.w.f; the bath ratio is 1:20-50. By means of the application of the ultrasonic technology to hemp fiber dyeing, the dye-uptake of the reactive dye can be greatly raised, the dyeing temperature is lowered, and the dyeing time is reduced.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to an application method of ultrasonic technology in textile dyeing. Background technique [0002] Ultrasonic technology has gradually been used in many textile processes, such as scouring and bleaching processes. The role of ultrasonic waves in the scouring process is mainly due to the cavitation of ultrasonic waves, which makes a series of effects occur, such as dispersion, emulsification, washing and depolymerization. The cavitation effect of ultrasonic waves is mainly to reduce the surface tension of the dirt adhering to the fibers. Therefore, it can clean the dirt on various surfaces and recesses, and at the same time, the cavitation can emulsify the dirt and grease, so that these dirt can be removed more easily. The dispersion of ultrasonic waves can isolate the colloids and fibers on the surface of the hemp, and then remove the colloids through the depolymerization o...
