Benefits of technology

This new type of chemical can be made more environmentally friendly without increasing its costs or making it difficult for people who are trying to use them because they may have negative health consequences if their skin comes into contact with these substances over time.

Problems solved by technology

The technical problem addressed by this patented method for producing dyestuff on fabrics involves traditional methods requiring heat during dyeings which consume significant amounts of power compared to contemporary processes involving chemical agents like bleachers. This results in increased costs associated with waste disposal issues due to excessive use of expensive materials used therein.

Embodiment 1

[0012] Take a package of yarn, add 1.8g of dyes AEL Yellow, 26g of AEL Claret, 139g of AEL Zhangqing, add 40kg of water to mix, add 3170g of Yuanmingfen at room temperature, then heat to 40°C, and wait 15 minutes after the temperature reaches 40°C Add 198g of soda ash, add 59g of caustic soda after another 15 minutes, wait for 50 minutes and then wash with water and soap.

Embodiment 2

[0014] Take a package of yarn, add 2.2g of dyes AEL Yellow, 28g of AEL Claret, 141g of AEL Zhangqing, add 40kg of water to mix, add 3230g of Yuanmingfen at room temperature, then heat to 40°C, and wait 15 minutes after the temperature reaches 40°C Add 202g of soda ash, add 61g of caustic soda after another 15 minutes, wait for 50 minutes, then wash with water and soap.

Embodiment 3

[0016] Take a package of yarn, add 2g of dyes AEL Yellow, 27g of AEL Claret, 140g of AEL Zhangqing, add 40kg of water to mix, add 3200g of Yuanmingfen at room temperature, then heat to 40°C, and add after 15 minutes after the temperature reaches 40°C 200g of soda ash, after another 15 minutes, add 60g of caustic soda, wait for 50 minutes, then wash and soap.

[0017] Since this dyeing process adopts the temperature condition of 40°C and uses caustic soda instead of soda ash, this dyeing process not only saves energy consumption, but also saves the cost of auxiliaries, and has less harm to the environment and human health.

Abstract

The invention relates to a deep navy reactive dye fixing agent, comprising the following components by weight: 1.8-2.2 parts of AEL yellow, 26-28 parts of AEL purplish red, 139-141 parts of AEL navy, 3170-3230 parts of anhydrous sodium sulfate, 198-202 parts of sodium carbonate and 59-61 parts of sodium hydroxide. A production process comprises the following steps: mixing the AEL yellow, the AEL purplish red, the AEL navy and 40kg of water under room temperature, adding the anhydrous sodium sulfate, heating the mixture to 40 DEG C, adding the sodium carbonate 15min later, then adding the sodium hydroxide 15min later and carrying out washing and soaping 50min later. The reactive coloring agent produces less pollution, has lower production cost and is economical and practical.
