Problems solved by technology

From this point of view, it is mainly due to the difficulty in cleaning the dyeing liquid pipes of the dyeing equipment, which will bring oil stains to pure cotton fabrics.
The current conventional method for cleaning pipes is mainly to add acid, alkali, oxidant, hydrosulfite, etc., but through experiments, it is found that after cleaning the pipes with these cleaning agents, the oil stains on the dyed cotton fabric cannot be eliminated.

Embodiment 1

[0026] A method for eliminating oily stains on dyed pure cotton fabrics, comprising the steps of:

[0027] 1) Before dyeing, clean the dyeing device system including the emulsification tank, the dyeing batching tank and the dyeing tank with multiple dyeing liquid pipes leading into the dyeing liquid; the cleaning agent is the complex of caustic soda and hydrogen peroxide, the amount of caustic soda and hydrogen peroxide The ratio is 4:1.

[0028] 2) When dyeing, add the defoaming agent into the emulsification tank with other dyeing auxiliaries, do not stir the emulsification tank immediately, continue to stir for 2-5 minutes after 3 minutes, and then send the stirred dyeing auxiliaries into the dyeing process .

Embodiment 2

[0030] A method for eliminating oily stains on dyed pure cotton fabrics, comprising the steps of:

[0031] 1) Before dyeing, clean the dyeing device system including the emulsification tank, the dyeing batching tank and the dyeing tank with multiple dyeing liquid pipes leading into the dyeing liquid; the cleaning agent is the complex of caustic soda and hydrogen peroxide, and the The dosage ratio is 5:1.

[0032] 2) When dyeing, add the defoaming agent into the emulsification tank with other dyeing auxiliaries, do not stir the emulsification tank immediately, continue to stir for 2-5 minutes after 5 minutes, and then send the stirred dyeing auxiliaries into the dyeing process .

Embodiment 3

[0034] A method for eliminating oily stains on dyed pure cotton fabrics, comprising the steps of:

[0035] 1) Before dyeing, clean the dyeing device system including the emulsification tank, the dyeing batching tank and the dyeing tank with multiple dyeing liquid pipes leading into the dyeing liquid; the cleaning agent is caustic soda, hydrogen peroxide and oil emulsifier, caustic soda and hydrogen peroxide The dosage ratio is 6:1, the densities of caustic soda and hydrogen peroxide are both 35g / L, and the oil emulsifier is 8% of that of caustic soda and hydrogen peroxide.

[0036] 2) When dyeing, add the defoaming agent into the emulsification tank with other dyeing auxiliaries, do not stir the emulsification tank immediately, continue to stir for 2-5 minutes after 5 minutes, and then send the stirred dyeing auxiliaries into the dyeing process .

Abstract

The invention discloses a method for eliminating oil stains of dyed cotton fabric. The method includes the following steps that before dyeing is carried out, a dyeing device system comprising an emulsifying jar, a dyeing material jar and a dyeing jar with multiple dye-liquid pipes for leading into dye liquid is cleaned; when dyeing is carried out, antifoaming agents are added into the emulsifying jar filled with other dyeing auxiliaries, the emulsifying jar is not stirred at once, after 3-8 min, stirring is carried out for 2-5 min, and the stirred dyeing auxiliary liquid is sent to the dyeing procedure. By means of the method, the oil stain rate of the dyed cotton fabric can be effectively decreased, the oil stain rate of the dyed cotton fabric is decreased to 5% or below from 85% or above, the product qualification ratio is increased, and losses and waste of raw materials are reduced.

Description

technical field [0001] The invention relates to the field of dyeing processing, in particular to a method for eliminating oil stains on dyed pure cotton fabrics. Background technique [0002] After the pure cotton fabric is dyed, the dyed finished product often has various oil stains. In this case, dyeing rework is often caused. Before the dyeing rework, the oil stains on the pure cotton fabric need to be cleaned, which makes the whole dyeing process complicated and labor The time and labor intensity increase, and the cost increases while also causing a waste of resources. [0003] The equipment involved in the dyeing process mainly includes emulsification tanks, dyeing batching tanks, and dyeing equipment with many dyeing liquid pipelines. The emulsification tank and the dyeing batching tank are often cleaned, and it is not easy to bring oil stains during the dyeing process. The large dyeing tank liquid of the dyeing equipment is often cleaned, and the possibility of oil s...
