Problems solved by technology

[0002] During the dyeing process of cotton-containing knitted fabrics in the dyeing vat, it is necessary to use a cloth lifting wheel to lift the fabric so that the fabric runs in the dyeing vat. When the fabric runs in the dyeing vat, the speed reaches 200m / min or above. The running time of the fabric in the dyeing vat is long, reaching 11 hours or more. There is a relatively large friction force between the fabric and the cloth lifting wheel of the dyeing vat, which often scratches the surface of the fabric and produces scratches, which affects product quality. Severe scratches need to be reworked

Embodiment 1

[0036] The present embodiment is a dyeing method of cotton-containing knitted fabric, comprising the following steps:

[0037] Pre-treatment: add caustic soda 4g / L, hydrogen peroxide 3.6g / L, penetrant 0.5g / L to the main tank of the dyeing machine, then heat up to 98 degrees, run for 45 minutes, cool down and drain, add acetic acid 1g / L after washing twice with water L and deoxygenase 0.12g / L, drain water after running for 10 minutes, and finish the pretreatment step.

[0038] Dyeing: After the main tank of the dyeing machine is filled with water, add 80g / L of Yuanming powder, then heat it up to 60 degrees, add 5% dye, after running for 30 minutes, add 25g / L of soda ash, continue to run for 45 minutes, drain the water to end the dyeing step.

[0039] Soaping: The main tank of the dyeing machine is washed three times with water, then add 1g / L of soaping agent into the water and heat it up to 90 degrees, run for 10 minutes, drain the water, and then clean it twice with water and ...

Abstract

The invention relates to a dyeing method of a cotton-containing knitted fabric. The method includes the following steps of preprocessing, dyeing, soaping, enzyme washing, and color fixing and softening. The enzyme washing step includes the substeps of water adding, heating, material adding, heat preserving and enzyme killing. Through the removal effect of cellulase on cotton fiber, cellulase reacts with cotton fiber in the enzyme washing process, laid fiber at scratches are washed away, scratches are repaired, scratch spots on the surface of the fabric are reduced on the aspect of vision, product quality is improved, and the rework cost caused by scratches is reduced.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a cotton-containing knitted fabric and a dyeing method thereof. Background technique [0002] During the dyeing process of cotton-containing knitted fabrics in the dyeing vat, the fabric needs to be lifted by a lifting wheel to make the fabric run in the dyeing vat. When the fabric is running in the dyeing vat, the speed reaches 200m / min or more. The running time of the fabric in the dye vat is long, reaching 11 hours or more, and a relatively large friction force is generated between the fabric and the cloth lifting wheel of the dye vat, which often causes the surface of the fabric to be scratched, resulting in scratches, which affects the quality of the product. Severe scratches require rework. The problem of scratches in the dyeing process of cotton-containing knitted fabrics is a worldwide problem in the current dyeing field, and the problem of scratches has alway...
