Competitive study between Natural dye and Synthetic dye in case of dying of 100% Nylon fabric

Abstract

This study was aimed to make a comparison between natural dyes and synthetic dyes based on different fastness properties and the costing of the dyes and their dyeing procedure. We used turmeric powder as our natural dye and acid dye as synthetic dye. As we know that the textile materials have lower affinity to the natural dye, so a mordant is needed to be used to increase the affinity between textile fibre and dye molecules. We used here two types of mordant Aluminium Sulphate and Ferrous Sulphate in our study. We found here different result based on different criteria like shade% of dye, types of mordant and the concentration of the mordant. Where the fabric mordanted by alum provides good fastness properties than the fabric mordanted by ferrous sulphate. We also observed that in case of acid dyeing it was more cost effective than the natural dyeing and the cost difference was fluctuated between different mordant we used. Rather our study found that the color fastness properties is better in case of acid dyeing than the natural dyeing. Hence we all know natural dyes are more environment friendly than the synthetic dyes like acid dyes. After all our study is imperative to make a comparison between turmeric colorant and acid dye.
