UV Protection Property of Colorant from Lac for Silk Fabric Dyeing by Cold Pad-Batch: The Influence of Metal Mordants Concentration

Article Preview

Abstract:

In the present study, natural dye from lac dye and various metallic salts have been used to identify the proper dyeing condition for attaining high quality natural dyeing along with imparting UV protection property to the dyed silk fabric. Silk fabrics dyed with lac extract showed a light pink shade, while those dyed with alum and stannous chloride pinkish-red colour. Silk substrates dyed with CuSO4 gave a purple red colour, while those dyed with FeSO4 had a reddish-gray colour. The fastness properties ranged from fair to good, while washing fastness was poor level. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between very good and excellent for the silk fabric.
