UV-Protection Property of Silk Fabric Dyed with Natural Indigo by Using Padding Technique: A Focus on Effect of Ferrous Sulfate Mordant

Article Preview

Abstract:

Silk fabric has been dyed with natural indigo (Indigofera tentoria) in absence and present ferrous sulfate mordant by using post-mordanting and pad dyeing processes. It was observed that with an increase in the dye concentration, the ultraviolet (UV) protection factor (UPF) values ranged between good and very good for the silk fabric. Silk fabrics dyed with natural indigo showed green shade. The level of fastness properties were ranged from good to very good. The results confirmed that natural dyes from natural indigo with ferrous sulfate have potential applications in fabric dyeing and in producing UV-protective silk fabrics.
