Abstract

The invention relates to the technical field of blended fabric, in particular to a water-saving dyeing production process of blended fabric with high color fastness. The process comprises the following steps of A, sample cloth selecting, B, gray cloth pre-shaping, C, desizing, boiling off and bleaching one-bath treatment, and D, dyeing. The process has the beneficial effects that the three steps of processing of conventional desizing, boiling off and bleaching are combined into one step to be completed, desizing, boiling off and bleaching one-bath treatment can save the treatment time to a great degree, and water consumption for dyeing of the blended fabric is well reduced; for pretreatment of the blended fabric, the optimal pretreatment process is the desizing, boiling off and bleaching one-bath method with the bath ratio of 1:20, and more water is saved; and the difference between water consumption of dyeing under the condition that the bath ratio is 1:1 and water consumption of dyeing under the condition that the bath ratio is 1:50 is 98%, and therefore for the one-bath dyeing method of the blended fabric, the dyeing bath ratio is selected to be 1:1, more water is saved, when the dye liquor amount is 50 mL, the contact time of the blended fabric and the dye liquor is 20 min, and the concentration of a leveling agent is 2 g / L, the dyeing performance of the fabric is better, and water is relatively saved by 80%.

Description

technical field [0001] The invention relates to the technical field of blended fabrics, in particular to a production process for water-saving dyeing of blended fabrics with high color fastness. 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 enterprise profit, and it is also a systematic project to improve product quality and product grade; improving dyeing and finishing energy-saving and water-saving technology is the common expectation of dyeing and finishing enterprises, and it is a hot spot of research and exploration in the whole...
