A Comparative Study on Sustainable Dyeing of Silk and Wool with Acid Red 138 Dye

ABSTRACT

Environment-friendly textile processing is now-a-days worldwide demand. The current study has been concerned with the utilization of suitable tool i.e. microwave radiation for the improvement of dyeing behavior of natural fabrics using Acid Red 138 dye. Microwave treatment up to 6 min has been given to both dye solution and fabrics. Microwave-treated and un-treated fabrics were used to dye under-treated and un-treated solutions. Different dyeing parameters were employed and shade made at optimized conditions were as per ISO fastness standards and it was found that un-heated silk has given excellent results when dyed at 65^◦C for 65 min under irradiated dye solution of 4 pH containing 4 g/100 mL of salt. But irradiated wool has given good results when the solution of 1 pH contaminating 4 g/100 mL salt was irradiated to dye fabrics at 65 ^◦C for 65 min. However, silk fabric has shown more promising behavior toward treated dye solution as compared to wool fabric under optimum conditions. It is concluded that microwave treatment has a good potential not only to make acid dyeing process more sustainable for the coloring behavior of silk more than wool under mild condition.

摘要

环境友好型纺织品加工现在是全世界每天的需求. 目前的研究是利用合适的工具, 即微波辐射来改善酸性红138染料对天然织物的染色性能. 为此, 对染料溶液和织物进行了长达6分钟的微波处理. 用微波处理和未处理的织物对未处理和未处理的溶液进行染色. 采用不同的染色参数, 在优化条件下制得的色光符合ISO牢度标准, 结果表明, 在65℃染色时, 未加热的真丝具有优异的染色效果◦在含有4 g/100mL盐的4 pH辐照染料溶液中, 在C下放置65 min. 但是, 当在65℃下将污染4g/100ml盐的1pH溶液辐照到染色织物时, 辐照羊毛产生了良好的效果◦持续65分钟. 然而, 在最佳条件下, 与羊毛织物相比, 真丝织物对处理后的染料溶液表现出更为良好的性能. 结果表明, 微波处理不仅使酸性染色过程更加可持续, 而且在温和条件下, 丝绸的染色性能优于羊毛.
