Abstract

The present invention relates to a continuous saltless pad-steam dyeing method with reactive dyes, which belongs to the novel technical field of textile printing and dyeing. After being singed, desized, boiled, bleached and mercerized, the half-finished product of cellulosic fibre woven fabric is dyed in the process of the continuous dyeing technique of padding, steam fixation, water washing, soaping, water washing and drying by the reactive dyes. The half-finished product of the preprocessed cellulosic fibre woven fabric is produced by pad dyeing, steaming and water washing, wherein, dyeing solution is composed of M reactive dyes, leveling agent, fixation alkali agent and water, and the mixture ratio is as follows: M reactive dyes: 0.01 percent to 10 percent, leveling agent: 0.1 percent to 0.2 percent, fixation alkali agent: 1.5 percent to 4 percent, and water: balance. The method is different from the conventional continuous dyeing technique of padding, drying, padding and steaming,which uses reactive dyes, and also different from the shortened wet-steaming technique with reactive dyes. On the conventional continuous padding machine, the novel method can fulfill the whole process of reactive dyeing without a hot-air padding machine and only with a developing and soaping range, thus greatly saving energy and reducing cost.
