Problems solved by technology

Under this technical route, even if the technicians in the industry improve the dyeing equipment, the water consumption required for dyeing has not been significantly reduced, the bath ratio has been significantly reduced, and the sewage discharge during the dyeing process is still large, which directly leads to the comprehensive Higher costs and lower profits put a lot of pressure on environmental protection

specific Embodiment

[0027] Adopt dyeing device of the present invention to dye 48-50 S New Zealand washes 180Kg of wool, only 250Kg of water, and the liquor ratio is 1:1.4. The dyeing prescription and dyeing process are as follows:

[0028] Dye Recipe:

[0029] Lanaset Red 2B 0.31%

[0030] Lanaset Yellow 2R 0.58%

[0031] Lanaset Lan 2R 0.068%

[0032] Leveling agent D 0.25%

[0033] Glacial acetic acid 0.8%

[0034] Dyeing process:

[0035] Circulate the dye solution in the dyeing device through the pump, first raise the temperature to 40°C, add leveling agent, keep it for 5 minutes, then add dye, keep it for 5 minutes, then add glacial acetic acid, keep it for 5 minutes, then, add the dye at 1°C Raise the temperature to 98°C at a heating rate of 1 / min, keep it for 1 hour, then lower the temperature, and rinse the floating color.

[0036] This method can achieve:

[0037]1. Save dyes and auxiliaries: With the decrease of bath ratio, the concentration of dye auxiliary materials in dye l...

Abstract

The invention relates to a fiber compressing dipping bath-free dyeing method in a super low liquor ratio. In the method, materials to be dyed are forcedly compressed, and are dyed by flowing dye liquor penetrating the materials to be dyed in a compression state. The compression volume of the materials to be dyed is usually between 0.4 and 0.5g / cm3; and the liquor ratio of the mass of the materials to be dyed to the mass of the used dye liquor is smaller than or equal to 1:2. The method realizes stock dyeing in the super low liquor ratio, reduces water consumption of dyeing and maximum discharge loading, improves the dyeing uniformity, effectively lightens the pollution of sewage to environment, reduces production cost, and can be mainly used for dyeing loose fibers, fiber rods, yarns and the like of various natural or chemical fibers.

Description

technical field [0001] The invention relates to a fiber compact non-immersion bath ultra-small liquor ratio dyeing method, which can be mainly used for dyeing various natural or chemical fiber loose fibers, fiber strips or yarns. Background technique [0002] Existing fiber dyeing methods are mainly divided into: bulk fiber dyeing, fiber strip dyeing, yarn dyeing, finished product dyeing (piece dyeing, garment dyeing) and the like. Each dyeing method has its own dyeing equipment, such as: loose wool dyeing machine, top dyeing machine, yarn dyeing machine, rope piece dyeing machine, etc. Since different materials to be dyed require different dyeing equipment, it not only increases the cost of the production equipment, but also requires a large production space. [0003] In the textile dyeing industry, the bath ratio refers to the mass ratio of the material to be dyed to the dye solution used. The more dye solution used for the same amount of material to be dyed, the greater ...
