Problems solved by technology

[0002] The original silk dyeing process generally adopts the method of circulating for 3 hours per cylinder. Due to the uneven temperature of the left and right sides of the cylinder, it is easy to produce coloring speed, resulting in color difference of the fabric and easy to cause scratches. Half of the time in operation is soaked in In the dyeing solution, half of the time is out of the dyeing solution, and the secondary dyeing doubles the dyeing time

Embodiment

[0026] The present invention proposes a kind of fast silk dyeing process with low liquid feeding rate, which is carried out according to the following steps:

[0027] 1. Dyeing preparation, drop cloth in the lower vat, set the high-efficiency silk dyeing temperature control system program, feed water 0.5T, add dyeing auxiliaries;

[0028] 2. The pretreatment temperature is raised, and the water temperature is raised from room temperature to 80°C at a speed of 1°C / min;

[0029] 3. Cool down, let out flowing water for 5 minutes to cool down to 40°C;

[0030] 4. For dyeing, add dyeing material and heat up to 80°C at a rate of 1°C / min;

[0031] 5. Keep warm for 30 minutes;

[0032] 6. Cutting samples and matching colors, cutting samples and standard colors for comparison;

[0033] 7. After the color matching is normal, enter the water, cool down to room temperature for 10 minutes, and then discharge the water;

[0034] 8. Wash the cloth out of the tank, wash the cloth with dei...

Abstract

The invention discloses a low-liquor-feeding-rate rapid silk dyeing technology. According to the low-liquor-feeding-rate rapid silk dyeing technology, dyeing is achieved by conducting dip dyeing and jet dyeing on shell fabric, external circulation of dye liquor in a cylinder body is added, in this way, the liquor feeding rate is lowered greatly, dyeing time is shortened, energy consumption is reduced, and the quality of products is improved.

Description

technical field [0001] The invention relates to a silk dyeing process, which belongs to the field of dyeing process manufacturing. Background technique [0002] The original silk dyeing process generally adopts the method of circulating for 3 hours per cylinder. Due to the uneven temperature of the left and right sides of the cylinder, it is easy to produce coloring speed, resulting in color difference of the fabric and easy to cause scratches. Half of the time in operation is soaked in In the dyeing solution, half of the time is out of the dyeing solution, and the time for promoting dyeing is doubled for secondary dyeing. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a rapid silk dyeing process with low liquid feeding rate. [0004] Technical scheme of the present invention is as follows: [0005] The present invention proposes a kind of fast silk dyeing process with low liquid fe...
