Design and application of highly stable continuous roll dyeing reactive dyestuff dyeing scheme
摘要
Abstract
To improve the stability and color fixation effect of continuous pad dyeing with reactive dyes,this study developed a novel reactive dye pad-batch dyeing process by adding alkali agents to the dye bath and precisely controlling the pre-drying temperature and time.The effects of alkali type,dosage,and pre-drying conditions on the color fixation rate were systematically investigated.The composition of dyes on the fabric after pre-drying and the applicability of dyes were analyzed,and pilot-scale experiments were carried out to verify the feasibility of the scheme.The results showed that when Na2CO3 was used as the alkali agent(dosage 5 g/L)with pre-drying at 80℃for 3 min,the color fixation rate of various re-active dyes could be increased by 2%-5%under the same steaming fixation conditions.In the pilot-scale experiment,the K/S value of the fabric samples treated by this scheme was significantly improved,and the color difference within the 2 000 m processing interval was smaller than that of the conventional process,which not only improved the product quality but al-so reduced the control difficulty of the production process.关键词
