回用染色废水用于羊毛织物活性染料染色
Reactive Dyeing of Wool Fabric Using Recycled Dyeing Wastewater
摘要
Abstract
Aiming to solve the problem of large discharge and severe pollution of reactive dyeing wastewater for wool fabrics,peroxodisulfate(SPS)was used for the degradation and recycling of dyeing wastewater containing reactive dye Lanasol Red CE.The process of degrading the reactive dye was determined by using the dye residual rate as the evaluation index.The feasibility of reactive dyeing of wool fabrics using recycled dyeing wastewater was confirmed by measuring the dye uptake,exhaustion and fixation rates,as well as color parameters and fastness of the dyed fabrics.The results showed that the appropriate conditions for degrading Lanasol Red CE were 0.2 g/L SPS,an initial pH value of 3 and 100℃for 30 min.Under these conditions,the dye degradation rate was as high as 93.14%.When the recycled dyeing wastewater was used for dyeing of wool fabrics,the exhaustion rate of Lanasol Red CE exceeded 99%,and the fixation rate was higher than that achieved by the conventional dyeing process.Under the same dyeing conditions,the recycled-dyed fabrics appeared darker.When the number of cycles was fewer than five,the effect on color fastness was not obvious.Although the color fastness to rubbing and washing of the fabrics dyed in the 10th cycle decreased by half a grade and 1 grade,respectively,compared to that of the fabrics dyed with the conventional dyeing process,they still met the production requirements.关键词
