Embodiment

[0023] 100% Australian wool, skein, dyed fruit green, weight 120kg.

[0024] 1. Dye:

[0025] Acid Bright Yellow 2G, the dosage is 0.14% of wool weight;

[0026] Acid lake blue A, dosage is 0.08% by weight of wool.

[0027] 2. Additives:

[0028] Sulfuric acid in an amount of 2% by weight of wool;

[0029] Yuanming powder, the dosage is 5% of wool weight;

[0030] Low-temperature dyeing accelerator SY-7, the dosage is 2% of wool weight.

[0031] 3. Dyeing equipment: skein dyeing machine S-300, horizontal (Qianzhou Yangjia Dyeing Equipment Factory, Wuxi).

[0032] 4. Dyeing process:

[0033] The skeined Australian wool yarn is cleaned and put into the machine. After fully soaked, add sulfuric acid, sodium sulfate, and low-temperature dyeing accelerator SY-7 at 25°C, and run for 20 minutes; 1'Heat up to 65°C, keep the temperature constant for 30 minutes; add 1% sulfuric acid, keep the temperature constant for 30 minutes, cool down and leave the machine.

Abstract

The invention relates to a wool low temperature dyeing process, which adopts dyeing process and dyeing equipment in prior art. The dyeing process mainly includes: adding sulphuric acid, glauber salt, low temperature accelerating agent SY-7, operating for 20 minutes; adding adequately dissolved acid color, heating to 65 DEG C. according to 1 DEG C. per 1 minute, keeping the temperature for 30 minutes; adding 1% sulphuric acid, keeping temperature for 30 minutes, reducing the temperature. The invention has beneficial effects: (1) simple in process, easy to operate, with great dyeing and fixation effect; (2) energy and water resource saving, pollution reducing, having great economic and social benefit; (3) color and adjuvant saving, product cost reducing.

Description

technical field [0001] The invention relates to a fiber dyeing process in the textile field, in particular to a wool low-temperature dyeing process. Background technique [0002] The traditional wool dyeing process is to add sulfuric acid, sodium sulfate, and leveling agent at 25°C, then add fully dissolved acid dyes, raise the temperature at 1°C / 1′ to 60°C for 10 minutes, and then press 1°C / 1.5′ Raise the temperature to 100°C for 60 minutes, then cool down and leave the machine. The disadvantage of this process is that it consumes a large amount of steam, water, and electricity; It is necessary to add a variety of color-fixing agents, which increases the dyeing cost and increases the pollution discharge. Contents of the invention [0003] In order to overcome the shortcomings of the traditional wool dyeing process, the invention provides a wool low-temperature dyeing process. [0004] The technical scheme of the present invention is achieved in this way. [0005] A wo...
