Olive green dye color fixing agent and dying process thereof

Abstract

The invention relates to an olive green dye color fixing agent. The color fixing agent comprises the following components in parts by weight: 1-1.5 parts of DB yellow, 0.5-0.6 part of BD red, 0.5-0.7 part of BD blue, 60-65 parts of anhydrous sodium sulphate, 30-33 parts of soda and 2-3 parts of color fixing agent. The dying process comprises the following steps of: heating up to 60 DEG C, and adding the color fixing agent; 5 minutes later, adding mixed dye of the BD yellow, the BD red and the BD blue; 10 minutes later, adding 1 / 3 of anhydrous sodium sulphate; another 10 minutes later, adding 2 / 3 of anhydrous sodium sulphate; 20-30 minutes later, adding 1 / 4 of soda; another 10 minutes later, adding 3 / 4 of soda; and carrying out water washing and soap boiling after waiting for 30-60 minutes. The color fixing agent has the advantages of less active dye pollution, lower production cost, and high product percent of pass, and easiness of operating the whole dying process.

Description

technical field [0001] The invention relates to a color-fixing agent for dyes, and also relates to its dyeing process, in particular to an olive-green dye color-fixing agent and its dyeing process. Background technique [0002] The current conventional dyeing is common reactive dye fixing agent, such as figure 1 , under the dyeing process conditions of 40°C, add leveling agent, dyes GTL brown, black G, 4BL yellow and 4BS scarlet, and then heat to 98-100°C, during the heating process, gradually add sodium sulfate, keep warm Dye for 20 minutes, then gradually warm to 70°C, and then wash with water. During the whole dyeing process, the temperature difference is large, from 40°C to 98-100°C, and then heated to 70°C, the whole process needs to consume a lot of electricity or coal, so the cost of product dyeing is high, and because of the temperature difference Large, it is easy to cause dyeing unevenness, resulting in dyeing deviation, therefore, the product qualification rate ...

AI Technical Summary

Problems solved by technology

During the whole dyeing process, the temperature difference is large, from 40°C to 98-100°C, and then heated to 70°C, the whole process needs to consume a lot of electricity or coal, so the cost of product dyeing is high, and because of the temperature difference Large, it is easy to cause dyeing unevenness, resulting in dyeing deviation, therefore, the product qualification rate is relatively low; in addition, because the temperature during washing is 70 ° C, due to the high temperature, it takes a lot of water to rinse to clean, that is, It will inevitably bring a lot of sewage. With the enhancement of people's awareness of environmental protection laws and the improvement of national environmental protection regulations, this production process is no longer in line with modern dyeing processes.
