Embodiment 1

[0027] Put the cotton gray cloth into the water, add H to the bath 2 o 2 and NaOH, heat up to 98°C, keep warm for 45 minutes; cool down to 80°C, drain into water; add glacial acetic acid, run for 10 minutes, drain into water; add deoxygenase, run for 10 minutes; finally dyeing.

Embodiment 2

[0029] Put the cotton gray cloth into the water, add H to the bath 2 o 2 and NaOH, heat up to 98°C, keep warm for 45 minutes; cool down to 80°C, drain into water; add glacial acetic acid, run for 10 minutes, drain into water; add deoxygenase, run for 15 minutes; finally dyeing.

Embodiment 3

[0031] Put the cotton gray cloth into the water, add H to the bath 2 o 2 and NaOH, heat up to 98°C, keep warm for 45 minutes; cool down to 80°C, drain into water; add glacial acetic acid, run for 10 minutes, drain into water; add deoxygenase, run for 12 minutes; finally dyeing.

[0032] In terms of cost, compared with the prior art, the dyeing pretreatment method of cotton fabric of the present invention:

[0033] Calculated per ton of cloth (bath ratio is 1:8):

[0034] Water saving: save about 8 tons of water for one line;

[0035] Power saving: about 6 degrees;

[0036] Save time: about 10 minutes.

[0037] The dyeing pretreatment method of cotton fabric of the present invention, carries out boiling bleaching, acid neutralization on pretreatment, the third water of traditional craft is removed H 2 o 2 Processing is put into dye sync. Add deoxygenase to the same water that was dyed and run the machine for 12 minutes, after testing the residual H 2 o 2 Has been remov...

Abstract

The invention discloses a dyeing pre-treatment method of a cotton fabric, which specifically comprises the following steps that: a gray fabric is put into water, a scouring and bleaching additive is added to a first bath liquid, and the temperature is raised to 98 DEG C, and is kept holding for 45 minutes; after holding, the first bath liquid is cooled to 80 DEG C, and is discharged, and then thefabric is put into a second bath liquid; glacial acetic acid is added into the second bath liquid, and the second bath liquid is discharged, and then is put into a third bath liquid after the operation is carried out for 10 minutes; deoxy enzyme is added into the third bath liquid, and the operation is carried out for 10 to 15 minutes; and finally, dyeing is carried out. In the dyeing pre-treatment method of the cotton fabric, on the basis of ensuring the dyeing property, energy saving and cost reduction are realized.

Description

technical field [0001] The invention relates to the field of textile fabric treatment, in particular to a method for pre-dyeing cotton fabric. Background technique [0002] Cotton fabrics are widely manufactured and used for their comfort and breathability. The traditional pre-dyeing method of cotton fabric mainly includes three processes: boiling and bleaching + acid neutralization + enzyme deoxidation. Among them, the boiling and bleaching is completed in an alkaline environment. To make the cloth bottom achieve the required whiteness, it is necessary to add H 2 o 2 The scouring and bleaching process with alkali at a specific temperature is completed, and the reactive dyes used in cotton dyeing require the cloth surface to be treated to a pH value of 6-8, and the residual H in the cylinder 2 o 2 Will lead to poor color uptake of reactive dyes, such as H 2 o 2 If the remaining cloth is partially uneven, the coloring rate of the active material will also be uneven, res...
