Embodiment 1

[0035] This embodiment relates to a dyeing method in the process of preparing denim fabrics from cotton fibers. The dyeing method is a dyeing process for oxygen bleached cotton fibers before spinning. The steps include:

[0036] (1) Pretreatment: Make the cotton fiber after oxygen bleaching into a silk cake and put it into the dyeing vat, control the amount of cotton fiber and water according to the bath ratio of 1:5, and add additives to it;

[0037] (2) Dyeing: Add dye, sodium sulfate and alkali to the tank to dye the cotton fiber;

[0038] (3) Post-treatment: dyed cotton fibers are treated with oil to obtain dyed fiber products.

Embodiment 2

[0040] This embodiment relates to a dyeing method in the process of preparing denim fabrics from cotton fibers. The dyeing method is a dyeing process for oxygen bleached cotton fibers before spinning. The steps include:

[0041] (1) Pretreatment: make the cotton fiber after oxygen bleaching into a silk cake and put it into the dyeing vat, control the amount of the cotton fiber and water according to the bath ratio of 1:12, and add additives to it;

[0042] (2) Dyeing: Add dye, sodium sulfate and alkali to the tank to dye the cotton fiber;

[0043] (3) Post-treatment: dyed cotton fibers are treated with oil to obtain dyed fiber products.

Embodiment 3

[0045] This embodiment relates to a dyeing method in the process of preparing denim fabrics from cotton fibers. The dyeing method is a dyeing process for oxygen bleached cotton fibers before spinning. The steps include:

[0046] (1) Pretreatment: Make the cotton fiber after oxygen bleaching into silk cake and put it into the dyeing vat, control the amount of cotton fiber and water according to the bath ratio of 1:9, and add additives to it;

[0047] (2) Dyeing: Add dye, sodium sulfate and alkali to the tank to dye the cotton fiber;

[0048] (3) Post-treatment: dyed cotton fibers are treated with oil to obtain dyed fiber products.

[0049] In the above process, oxygen bleaching is to control the amount of cotton fiber and water according to the bath ratio of 1:6, and add hydrogen peroxide, hydrogen peroxide stabilizer, penetrant and scouring enzyme to it in order to control the concentration of hydrogen peroxide, hydrogen peroxide stabilizer and penetrant in the bath. The conc...

Abstract

The invention discloses a dyeing method for preparing a jean fabric from cotton fiber. The method includes the process for dyeing oxygen-bleached cotton fiber before spinning. The dyeing process includes the steps of preprocessing, dyeing and post-processing. By means of the method, in the preparation process of the jean fabric with the cotton fiber as the raw material, the oxygen-bleached cotton fiber is dyed, the jean fabric is prepared through spinning and other procedures after the oxygen-bleached cotton fiber is dyed through a fiber dyeing method, the problems that in the jean fabric production process, the yield is low and environment protection does not reach the standard are solved easily, and the method is suitable for wide use and popularization.

Description

technical field [0001] The invention relates to a dyeing method in the process of preparing denim fabrics from cotton fibers, in particular to a dyeing method for denim fabrics prepared from cotton fibers, and belongs to the technical field of denim fabric preparation. Background technique [0002] Traditional denim fabrics are made from pure cotton through spinning, dyeing, sizing, weaving and finishing. In order to improve the performance of denim fabrics, in the current denim market, there are also a series of blended fabrics, such as cotton / polyester (50 / 50) blended fabrics, and cotton and other fibers such as Tencel, linen, or even jute, wool Yarn and other fibers are woven together, which expands the categories and special requirements of denim fabrics, and develops special non-cotton denim fabrics with denim style. Such as patent documents CN105803761A (a production process of colored soft denim, 2016.07.27, D06M11 / 50), CN105200625A (a production method of micro-elas...
