Comparative Study on colorimetric & fastness properties of different dyes on cotton and viscose fabrics

Abstract

This research presents a comparative study of on colorimetric & fastness properties of 100% Cotton and 100% Viscose knitted fabric dyed with Reactive, Direct, Vat Dyes for 2% shade is reflectance% and carve ware contested and L.a.b.c values and K/S (Color Strength) also measured by using spectral meter color fastness to wash and rubbing test were performed to compare dyeing perform. The results should darker shade on viscose for all dyes than in cotton all most similar wash fastness values were found for reactive and vat dye on both fabric were as direct dye should poor results direct dye should lower (poor) wet rubbing fastness on both fabric then the other two dyes.
