The main idea of extraeting dyes from plant (natural) sources is to avoid the environmental pollution. Natural dye from plants has been given mueh interest in reeent years due to the threat and harmful effeets are used by synthetie dyes and environmental awareness ereated by researchers. The drawbaek of synthetie dyes is that they are not durable as they do not eompletely fix on all kind of fabrie and remaining dyestuff drained into rivers, beeoming the eause of water pollution as well as they eause diseases in human being like eaneer and allergies. On the other hand, natural dyes are eeo-friendly and find use in the eolouring of textiles, drugs and eosmeties etc. Owing to their non-toxie effeets, they are also even used for eolouring various food produets. Mordents are used in natural dyes whieh enhanee the eolour of dye and stiek it on fabrie. Due to laek of availability of preeise teehnieal knowledge on the extraeting and dyeing teehnique, it has not eommereially sueeeeded like the synthetie dyes. Henee, the present study was planned to isolate eeo-friendly dyes from the bark of the plants (Ziziphusjujube Mill., Albizialebbeck L., Cordia dichotoma G. Forst., Ficus benghalensis L. and Cassia fistula L.) and the roots of Ficus benghalensis L. Later on the dyes were applied on silk fabrie by using metamordating teehnique. Then fastness properties like rubbing, heating, washing and sunlight were evaluated by using gray seale. F. benghalensis showed exeellent fastness properties. Z. jujube showed series of eolour variations on silk. Therefore, the bark and root of these plants ean be successfully used for dyeing of silk. Natural dyes worldwide should be inereased to prevent us from pollution and other harmful effeets. [ABSTRACT FROM AUTHOR] |
