Ultrasonic Dyeing of Silk Fabric with Dirinaria picta Lichen Species
Keyword(s):
The aim of this work is to enhance dyeing efficiency and fastness properties of natural dyes from Dirinaria picta lichen species using ultrasound method. The dyes were extracted using boiling water, ammonia fermentation and solvent extraction methods. The time and temperature of ultrasound dyeing on silk fabrics were varied and compared with conventional dyeing. The results revealed that the efficiency of ultrasound dyeing is better than conventional dyeing in terms of giving darker shades on the fabrics. Ultrasound dyeing has the advantage of using lower dyeing temperature. The results of fastness properties to washing, perspiration, crocking and light were fair to good.
