Embodiment 1

[0019] Example 1: Take 20×16 T65 and C35 108×58 polyester cotton olive green gauze as an example; the specific process steps are as follows:

[0020] 1. Small sample dithering: through laboratory sample dithering, select disperse dyes: disperse ruby ​​H2GFL, disperse blue 2BLN, disperse yellow SE-RGFL; reactive dyes: reactive red B-3BF, reactive brilliant blue B-RV, reactive golden Color matching prescription of six dyes including B-4RFN;

[0021] 2. Prepare disperse and reactive dye dyeing solutions (dyeing solutions are prepared according to different hue requirements); the disperse dyes used are alkali-resistant disperse dyes; the reactive dyes used are high-temperature-resistant double-reactive B-type dyes;

[0022] 3. Put the polyester-cotton blended fabric into the high-temperature and high-pressure overflow dyeing machine;

[0023] 4. Slowly inject the mixture of disperse and reactive dyes into the high-temperature and high-pressure overflow dyeing machine, and then ...

Abstract

The invention discloses a cotton-polyester blended fabric and a dispersive and reactive dye one-bath dyeing process. The process is characterized by comprising the following steps: injecting dispersive and reactive dyes and bath materials into a high-temperature high-pressure overflow dyeing machine slowly; then adding Na2SO4 solution and Na2CO3 solution into the high-temperature high-pressure overflow dyeing machine slowly, and carrying out high-temperature high-pressure apposition dyeing on cotton-polyester blended fabrics in the mixed dispersive and active dyeing solution; and carrying out scouring, soaping, washing and drying to ensure that the cotton-polyester blended fabrics are fully subject to color fixing, thus finishing the whole dyeing process. Compared with the cotton-polyester blended fabric two-bath two-step dyeing process, the dyeing process of the invention has the advantages that the time is shortened to 2.5-3.5 hours from 5-7 hours, the water consumption is reduced by 35%-40%, the electricity consumption, the steam consumption and the worker labor strength are lowered, and the production efficiency of enterprises is improved.

Description

technical field [0001] The invention relates to a polyester-cotton blended fabric dyeing and finishing process, in particular to a polyester-cotton blended fabric dyeing process with disperse and reactive dyes in the same bath. Background technique [0002] Polyester-cotton blended fabric series products are very common in the international and domestic markets. It has a wide range of applications and a large market share; currently affected by the economic crisis, the demand in the civilian product market shows a trend of small batches, multiple hues, and tight delivery dates. Most printing and dyeing processing enterprises use overflow dyeing machines for dyeing; its production Low cost and low energy consumption, it is very suitable for dyeing small batches and many varieties of civilian products; but at present, some domestic printing and dyeing processing enterprises use disperse and reactive dye overflow machines to dye polyester-cotton blended fabrics, such as figure...
