Traditional cotton fabric processing and dyeing is carried out separately , using a two-bath pre-treatment and dyeing . This method is required process time is long , complicated operation , the amount of labor and water consumption and pollution heavy burden . Therefore , simplify the work of cotton woven fabric dyeing process has been an important issue in the dyeing and finishing workers . This paper mainly discusses cotton woven fabrics , scouring and bleaching and reactive dyeing one bath process . Appropriate choice of reactive dyes for dyeing of reactive dyes in one bath dyeing process parameters ( dyeing temperature , pH value of the alkaline agent , hydrogen peroxide , liquor ratio , fixing agent , with or without scouring additives ) for dyeing finished uptake rate, capillary effect , tear strength rubbing fastness identified suitable for cotton woven fabrics , scouring and bleaching and reactive dyeing one bath dyeing process . Of the process , in addition to the dye uptake was slightly lower , other aspects can reach the general level of the two-bath , has the advantage of shorter dyeing time , improve production efficiency , reduce energy consumption , save water and reduce the burden on the sewage treatment .
