Dyeability of Indian natural dyestuffs to fabrics was investigated. Indian dyestuffs are more inexpensivethan domestic dyestuffs purchased at oriental medicine stores. We studied the dyeability of madder, mari-gold, and pomegranate imported from India on cotton, silk, and wool fabrics. Dyebaths of a combinationratio of 80:20, 60:40, 50:50, 40:60 and 20:80 of madder and marigold, fabrics with orange colors weredyed. To evaluate the dyeability of dyed fabrics, K/S values, Munsell color values and CIE L, a, b, ∆Ewere measured. The dyeability of fabrics dyed in dyebaths of pH 4 and pH 7 were higher than pH 10. Thedyeability in pH 4 was better than pH 7. Silk fabrics dyed with madder and marigold showed good dyeabi-lity and wool fabrics showed good affinity in madder dyebath and fair affinity in marigold dyebath. Cottonfabrics showed fair affinity in a marigold dyebath of pH 4 and pH 7. Cotton fabrics dyed with a 60:40 ratioof madder and marigold showed 4.76YR of Munsell color value. Silk Fabrics dyed with a 40:60 ratio sho-wed 4.76YR and wool fabrics dyed with 20:80 ratio showed 5.57RY. The ratios produced the closest colorsto 5.0YR of orange. This result indicated that marigold had a more powerful effect on cotton fabrics whilemadder was stronger on wool fabrics. Fading grades of washing colorfastness of wool and silk fabrics dyedin mixed dyebaths were higher than 3.5-4.0 and higher than homogeneous dyebaths. Staining grades of wa-shing colorfastness of all dyed fabrics were between grades 3.5-5.0. Colorfastness to dry-cleaning washigh as grades 4.0-5.0 in all of dyed fabrics. Colorfastness to light of dyed fabrics showed a fair grade of3.5-5.0; in addition, wool fabrics showed lower grades than silk and cotton fabrics.Key words: Indian natural dyes, Madder, marigold, Pomegranate, Mixed dyebath; , , , ,
