An ecofriendly reducing agent, viz. alkaline pectinase alongwith iron (II) salt, has been used in place of sodium hydrosulphite for dyeing of cotton with indigo. Dyed samples are then characterized by ATR-FTIR, SEM and XRD. It is observed that the alkaline pectinase alongwith iron (II) salt reducing system is also capable of producing almost identical level of reduction potential in dye baths, reduction bath stability, dye strength and colour fastness properties of dyed cotton to those obtained with sodium hydrosulphite.

使用碱性果胶酶和Fe(II)盐对靛蓝进行棉染色

一种环保的还原剂,即。碱性果胶酶与铁(II)盐一起已被用来代替亚硫酸氢钠用靛蓝染色棉。然后通过ATR-FTIR,SEM和XRD对染色的样品进行表征。观察到,碱性果胶酶与铁(II)盐还原系统一起还能够产生与使用亚硫酸氢钠获得的染料相比几乎相同水平的染浴还原电位,还原浴稳定性,染色强度和色牢度特性。
