Dyed Fabric

Natural dyes extracted from Cassia fistula and onion peels are used to dye wool that is pretreated with chitosan by using tannic acid as a mordant. The effect of the mordant concentration on the color strength (K/S) is discussed. The results obtained indicated that K/S increases after treatment with chitosan. It is also noticed that K/S increases with an increasing concentration of chitosan. K/S also increases with an increase of mordant concentration until 4% and then decreases. The effect of the dye bath pH, dyeing temperature and dyeing time are also studied. The K/S and dye uptake exhibit high values. Good fastness properties of the dyed fabric are achieved. The antimicrobial activity of chitosan-treated wool fabric is tested in accordance to diffusion agents. Test organisms, such as Escherichia coli, Bacillus subitilus Pseudomons aeruginosa and Staphylococcus aureus are used and the results indicate that the samples treated with a lower concentration of chitosan exhibit a smaller inhibition zone.

This research work involves the dyeing of silk fabrics with cochineal inset, Safflower yellow, gardenia blue, three kinds of natural dyes. Then, UV protection performance was analyzed. The results show that the fashion color that turquosice has been acquired through changing the proportion of each natural dyestuff in combination dyeing, simultaneously there will be a certain influence on the movement comfort performance.

Synthetic dyes and all the processing used in general dyeing is harmful to our health. Dye from natural sources can reduce the risk of synthetic dyes. As indigo has been used for thousands of years for the coloration of textiles as a natural source. This review is aimed at a discussion of different raw materials used for the extraction of natural dyes, the extraction process for different natural dyes, and the properties of fabric dyed by those dyestuffs. Most of the natural dyes showed a very good fastness property in researches. The dyes can be extracted from trees, bark, leaves, flowers, and many more sources. Most of the natural dyes exhibit special properties like anti-microbial, less toxicity, less allergenic, UV protection.
