The current research studied the dyeing properties and spectroscopic characteristics of natural dyes on PLA and PET fabrics. The natural dyes used were the dyes extracted from turmeric and cassumunar powder and the commercial dyes viz. Natural Orange and Natural Red Brown. The water solubility and partition of the dyes in octanol and water (logP) were studied. It was found that the dyes with poor water solubility that were the turmeric and cassumunar dyes exhibited a high degree of exhaustion and visual color yield (K/S) than the readily water soluble commercial dyes viz. Natural Orange and Natural Red Brown. Turmeric and cassumunar dyes can be used for dyeing PLA and PET fabrics to a medium-deep shade with the turmeric dye providing a deeper shade. The fluorescence properties of the turmeric and cassumunar dyes were examined on the PLA and PET fabrics and it was observed that the dyes exhibited a stronger fluorescence emission on PLA than PET for both turmeric and cassumunar dyes. Cassumunar dye displayed less fluorescence properties than turmeric dyes on both fabrics. The fluorescence emission properties of the turmeric dyes at different K/S levels were also investigated. |
