Abstract

The current study is aimed to explore the sustainable dyeing approach of silk fabric with turmeric powder using tannin as mordant extracted from tamarind seed coat. For that, tamarind seed coat tannin was extracted and applied as natural mordant alone and in combination with metal mordant namely copper sulphate for dyeing silk fabric with the extract of turmeric powder. Dyeing parameters such as temperature, time and mordant concentration were varying for optimizing the process. The color strength, color coordinates, color fastness to wash, perspiration, water and rubbing were evaluated for examining dyeing performance. Firstly, tannin was extracted from tamarind seed coat and applying on the silk fabric at 95°C temperature for 45 min by varying concentration. Among them 15 g/l shows better results. Some samples were mordanted with both 15 g/l extracted tannin and 0.5% copper sulphate solution. The mordanted samples were dyed with turmeric dye by varying the time and temperature. By analyzing the test results, the sample mordanted with extracted tannin showed high color strength and good fastness properties dyeing at 80°C for 60 min. The application of 0.5% copper sulphate mordant enhanced sustainable wash fastness properties.

Highlights

Tannin is one in every necessary natural mordant commonly called bean tree which is one in every foremost necessary utile tree species within the Indian sub-continent [1] [2]

Summary

Introduction

Tannin is one in every necessary natural mordant commonly called bean tree which is one in every foremost necessary utile tree species within the Indian sub-continent [1] [2]. Coloration of textiles with natural mordant associated graded dyes was a recent specialty of history. The kernels contain polysaccharides having an awfully sensible size property or utilized as a sizing agent for jute and textile yarns. The seed coat containing four-hundred water soluble matter is nothing a mix of tannins. It is used for wound healing associated degreed as an anti-dysenteric drug. With a specific astringent style, the profile of polyphenolics gift within the tamarind seed coat was found to be dominated by proanthocyanidin, meaning a group of compounds shaped by the condensation or chemical change of flavan-3-ol or flavan-3,4-diol, normally called condensed tannins or phlorotannin [17]
