Abstract:

The dyeing of wool fibers using saffron petals as a natural dye has been studied for first time in this paper. Saffron petal is one of the by-products of fields which are thrown away after harvesting while they can possibly be used. A series of dyeing formulation prepared with saffron petals and different mordants and the mordant effect on hue, light and wash fastness of dyed fibers were investigated. The K/S and CIELAB were used to determine the color of the fiber. The results of dyeing show that varied hues of color from light yellow to brown are obtained. The results of fastness properties of dyed fibers were fair to good. It was found that the best mordants in this study to improve wash and light fastness of dyed fibers were FeSO4 and Na2Cr2O7.

Using Eggplant Skin as a Source of Fruit Waste Colorant for Dyeing Wool Fibers

Today, natural colorants are emerging globally due to their safety and environmental friendly characteristics. Natural dyes have been employed in dyeing Persian carpet piles for many years. Food and fruit industry wastes are one of the main sources of colorants which can be employed for textile coloration. Eggplant (Solanum melongena), a member of the family Solanaceae, is used in food recipes....

Lipid Role in Wool Dyeing

The textile industry uses different fibers obtained from various animals, of which the wool from domesticated sheep Ovis aries is commercially the most important. Dyeing is one of the most important finishing procedures of wool processing. It almost invariably involves absorption of water-soluble colorants from aqueous solutions by the fibers. Diffusion is the process by which the colorant mole...

Dyeing of Indian wool with reactive dyes

Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...
