Embodiment 1

[0018] A composition for one-bath process of woven fabric dedyeing, its raw materials are calculated by mass percentage: sodium myristoyl glutamate 15%, sodium cocoyl isethionate 15%, sodium carboxymethyl cellulose 8%, diffuser MF 8%, and the balance is water.

[0019] The preparation method of the composition that is used for the one-bath process of woven fabric destaining, comprises the following steps:

[0020] (1) Weigh each raw material according to the formula ratio;

[0021] (2) Add sodium myristoyl glutamate and sodium cocoyl isethionate into the reaction kettle, then add water, and mix and stir for 20 minutes;

[0022] (3) Add sodium carboxymethylcellulose and stir for 20 minutes, then raise the temperature to 50°C, continue stirring for 10 minutes, and wait for the foam to disappear;

[0023] (4) Add the diffusing agent MF to the mixture in step (3), and then fully stir for 10 minutes to prepare the composition.

Embodiment 2

[0025] A composition for one-bath process of woven fabric dedyeing, its raw materials are calculated by mass percentage: sodium myristoyl glutamate 20%, sodium cocoyl isethionate 20%, sodium carboxymethyl cellulose 10%, diffusing agent MF 10%, the balance is water.

[0026] The preparation method of the composition that is used for the one-bath process of woven fabric destaining, comprises the following steps:

[0027] (1) Weigh each raw material according to the formula ratio;

[0028] (2) Add sodium myristoyl glutamate and sodium cocoyl isethionate into the reaction kettle, then add water, and mix and stir for 20 minutes;

[0029] (3) Add sodium carboxymethylcellulose and stir for 30 minutes, then raise the temperature to 55°C, continue stirring for 10 minutes, and wait for the foam to disappear;

[0030] (4) Add the diffusing agent MF to the mixture in step (3), and then fully stir for 10 minutes to prepare the composition.

Embodiment 3

[0032] A composition for one-bath process of woven fabric dedyeing, its raw materials are calculated by mass percentage: sodium myristoyl glutamate 25%, sodium cocoyl isethionate 25%, sodium carboxymethyl cellulose 12%, diffusing agent MF 12%, the balance is water.

[0033] The preparation method of the composition that is used for the one-bath process of woven fabric destaining, comprises the following steps:

[0034] (1) Weigh each raw material according to the formula ratio;

[0035] (2) Add sodium myristoyl glutamate and sodium cocoyl isethionate to the reaction kettle, then add water, and mix and stir for 30 minutes;

[0036] (3) Add sodium carboxymethylcellulose and stir for 30 minutes, then raise the temperature to 60°C, continue stirring for 10 minutes, and wait for the foam to disappear;

[0037] (4) Add the diffusing agent MF to the mixture in step (3), and then fully stir for 10 minutes to prepare the composition.

Abstract

The invention belongs to the technical field of textile auxiliary agents, and particularly relates to a composition for a woven fabric desizing and dyeing one-bath technology and a preparation methodthereof. The composition comprises the following raw materials in percent by mass: 15-25% of sodium myristoyl glutamate, 15-25% of sodium cocoyl isethionate, 8-12% of sodium carboxymethyl cellulose, 8-12% of a diffusant MF and the balance of water. The composition can be combined with other auxiliary agents, improves the coloring rate and the color fastness of fabric, has high dyeing rate, can effectively prevent a re-attachment phenomenon of a sizing agent or impurities dissolved or shedding in a water bath, has relatively strong dispersing and level dyeing capabilities, improves the dyeing quality, has a good overall dyeing effect, and can maintain a relatively good soft hand feel of the fabric.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to a composition used in a one-bath destaining process of woven fabrics and a preparation method thereof. Background technique [0002] Traditional woven fabric dyeing is generally divided into three-step process of "desizing-dyeing-reduction cleaning" and two-step process of "desizing-dyeing". The traditional dyeing process is not only time-consuming and laborious, but also high energy consumption and low efficiency. The one-bath destaining process of woven fabrics changes the traditional three-step or two-step method into a one-step desizing and dyeing process, that is, the fabric can be directly dyed under weak acid or weak alkaline conditions without draining water after desizing. The dyeing time is greatly shortened, energy consumption is saved, and environmental pollution is reduced. In the one-bath destaining process of woven fabrics, desizing and dy...
