EVALUATION OF FASTNESS PROPERTIES FORCOTTON FABRICS DYED WITH EXTRACT OF SAFFRON PETALS

Nowadays, there is a growing demand in natural colorants from plants because of negative impact of the synthetic ones. The natural dyes are non- toxic and eco-friendly. In this study extracted colorant from saffron petals is used. The dyeing process is conducted both with and without the use of mordants, employing three distinct mordanting methods: pre-mordanting, simultaneous-mordanting, and post-mordanting. The experimental results showed that the simultaneous-mordanting method produces good grades of fastness compared to pre-mordanting and post-mordanting methods. The fastness properties were improved by mordanting process in all cases. The fabrics gained different hues with different mordants resulting in different hue profiles.
