[0003] The existing method of dyeing blended fabrics consumes a lot of energy and causes serious pollution. The water consumption per ton of fabric in most dyeing factories is above 1:100
Most of the dyeing process adopts the intermittent production of dyeing machines from pretreatment to soft finishing. The liquor ratio is about 1:80, and the technology is backward. Large amount of repair, more water consumption; more caustic soda used, high COD of wastewater, sewage treatment can not meet the discharge standards

Abstract
The invention relates to a technology for dyeing blended cellulosefiber fabric. The technology includes the steps of 1, gray fabric preshaping; 2, reduction and washing; 3, dyeing-assistant formula designing and preparing; 4, dyeing; 5, finishing after color fixing. The key technology is that a dyeing assistant with special ingredients is added in the dyeing technology. The technology for dyeing the blended cellulosefiber fabric has the advantages that water is effectively saved, pollution is reduced, and meanwhile high color fastness is achieved; as the dyed fabric is subjected to color fixing and after-finishing wet short steaming through the prepared dyeing assistant, the color fastness of the dyed blended fabric is improved, water is greatly saved, and pollution is greatly reduced.
Description
technical field [0001] The invention relates to the field of fabric dyeing, in particular to a blended cellulosefiber fabric dyeing process. Background technique [0002] Energy conservation, emission reduction, consumption reduction, and environmental protection are the strategies to realize the sustainable development of the textile industry. The printing and dyeing link is the top priority for the entire textile industry to achieve energy conservation and emission reduction. The success of dyeing and finishing energy-saving technology is the most direct and effective energy-saving emission reduction. Engineering is the core of corporate profits, and it is also a systematic project to improve product quality and product grade. Improving energy-saving and water-saving technologies in dyeing and finishing is the common expectation of dyeing and finishing enterprises, and it is a hot spot of research and exploration in the whole country and even in the world. [0003] The e...
