Embodiment Construction

[0008] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0009] This example provides an improved process for post-dyeing cheese dyeing. The cheese is placed in a dyeing machine, and the post-treatment process is carried out after the dyeing process. First, the cheese is washed with water at 80°C for 8 minutes, and then the cheese is washed with water for 8 minutes. Drain the water out of the dyeing machine, continue to wash again with water neutralized by HAC for 8 minutes, keep the water temperature at 60°C, then drain the water again, then wash again with 80°C water for 8 minutes, drain the water after washing, and then Add saponification agent into water at 98°C, and carry out two high-temperature soaping for 16 minutes. After the soap ...

Abstract

The invention discloses an improved technology for cone yarn dyeing aftertreatment. The improved technology comprises the following steps: firstly washing a cone yarn for 8 minutes with water at the temperature of 80 DEG C, then discharging the water out a dyeing machine, continuously washing for 8 minutes again with water neutralized by HAC, maintaining water temperature to be 60 DEG C, then discharging the water again, then washing for 8 minutes with the water at the temperature of 80 DEG C, then discharging the water, then adding a saponifying agent into water at the temperature of 98 DEG C, carrying out high temperature soap boiling for 16 minutes twice, discharging liquid once the soap boiling is finished, then sequentially washing for 16 minutes with the water at the temperature of 98 DEG C, washing for 8 minutes with the water at the temperature of 80 DEG C, washing for 8 minutes with water at the temperature of 60 DEG C, and washing for 8 minutes with water at the temperature of 45 DEG C, finally adding a color fixing agent, a softening agent and a smoothing agent into the water at the temperature of 45 DEG C, and carrying out softening treatment for 32 minutes. High temperature soaping is carried out twice for treating the cone yarn, so that salt, alkali and unfixed dyes can be removed.

Description

technical field [0001] The invention relates to a package yarn production process, in particular to an improved post-treatment process after package yarn is dyed. Background technique [0002] In yarn production, it is usually necessary to dye the yarn, and then perform post-treatment to remove fixed dyes, salts and alkalis, so that the pH of the dyed fabric is close to neutral, so post-treatment is an important part of the entire dyeing process, but The existing post-treatment process is not effective, and it is easy to leave a large amount of hydrolyzed dyes on the fiber. The affinity of reactive dyes affects its washability. The washing treatment time is generally more than twice that of the dyeing and fixing process. , a large amount of water and heat are used for post-washing treatment, therefore, it is particularly important to solve this type of problem. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a...
