Natural Dyeing of Cotton Fabrics with Pigment Extracted from Roseomonas Fauriae
Journal Title: Universal Journal of Environmental Research and Technology - Year 2014, Vol 4, Issue 1
Abstract
Natural dyeing is a technique to dye the textile fabrics with the colours extracted from natural sources like plants, animals and minerals, microorganisms etc. They are eco-friendly, biodegradable and noncarcinogenic in comparison to synthetic dyes. In this research work, the pigment was extracted from Roseomonas fauriae using aqueous media. The dye potential of the extract was evaluated by dyeing on 100 % cotton fabrics under normal dyeing conditions. These findings reveal that the extract of pink pigment can be used for coloration of 100 % cotton. The relative colour strength of the dye was found to be more in case of cotton clothes mordant with alum. Air permeability of the treated cotton fabric was not much affected by the treatment. The slight decrease in tensile and tear strength was noticed in the treated samples. The aqueous pigment finished fabric has the best fastness criteria to washing. After treatment the stiffness of fabric was moderately increased.
