Abstract
This research was concerned with dye extraction from the bark of Garcinia Dulcis (Roxb.) Kurz and with the application of this dye for silk fabric dyeing by the pad-dry process. Silk fabrics dyed with Garcinia Dulcis (Roxb.) Kurz bark extract showed a pale yellow shade, while those dyed with alum and stannous chloride bright yellow and light yellow colour, respectively. Silk substrates dyed with CuSO4 gave a yellowishgreen colour, while those dyed with FeSO4 had a dark brown colour. The colour fastness to rubbing after dyeing the silk fabric treated with the mordant was investigated, the results of which showed fair to good fastness. The results confirmed that natural dyes from Garcinia Dulcis (Roxb.) Kurz bark extract have potential applications for fabric dyeing and producing ultraviolet (UV) protective silk fabric.
