Dyeing and application of natural fragrance using citrus plant component on silk fabric / Intan Nadirah Mohd Yusof

Due to the global awareness of the hazardous toxicity that comes from synthetic dyes, dyes from natural sources had gained back the attention by textile researchers. In this research, natural dye was extracted from the peels of calamondin fruit (Buah Limau Kasturi) whereas the juice and tamarind were used as the sources of mordant in the exhaustion dyeing process of silk fabric using the technique of meta-mordant. Besides that, kaffir leaves (Daun Limau Purut) were used in the dyeing process as the value added element in this research by including the effect of fragrance. Samples were evaluated and tested based on their colour composition, intensity of the fragrance after 5 times of washing and colourfastness properties towards washing, perspiration and rubbing/crocking. The shade of fabric obtained was yellow with a slight of green effect while the results of colourfastness to washing and rubbing/crocking were satisfactory. Based on the results from odour evaluation, samples dyed with tamarind as mordant was the most effective as the fragrance was able to sustain until the final wash cycle.
