One-bath dyeing process for cotton polyester textile fabric

The invention provides a one-bath dyeing process for a cotton polyester textile fabric. According to a scouring dyeing agent LS01 used in the dyeing process, a refined oil removal effect of the cotton polyester textile fabric is good, cotton fibers are well bleached, cottonseed hulls are completely removed, and disperse dyes are good in dye uptake effect and do not have selectivity. According to the dyeing process, refining of the cotton polyester textile fabric, cotton fiber bleaching and polyester dyeing are merged into one-bath one-step treatment, the process time can be greatly shortened, the single machine yield is improved, the water consumption is greatly reduced, discharge of sewage is reduced by 85.7%, the COD content of the sewage is reduced, the sewage discharge amount is greatly reduced, the production efficiency is facilitated to be improved, the production cost is reduced, the environmental pollution is greatly reduced, and the production process is environmentally friendly. 本发明提供了种棉涤纺织面料的浴染色工艺，
