Abstract

Dyeing properties of the colorants from gromwell on cotton fabric were investigated. The effects of dyeing conditions on dye uptake and the effects of mordants and mordanting methods on K/S value, color change and colorfastness were explored. Gromwell colorants showed low affinity to cotton fabric, and its adsorption isotherm was Freundlich type close to Langmuir type. Therefore, it was considered that hydrogen bonding and Vander Waals force were involved in the adsorption of gromwell colorants to cotton fabric. Pre-mordanting method except Sn mordant gave higher K/S value but it was not significant. Gromwell colorants produced mainly R and RP color on cotton fabric depending on mordants and mordanting method. Dyed cotton fabric showed generally high colorfastness irrespective of mordanting treatment. Light colorfastness was increased by repeat dyeing and Fe and Sn mordanting.
