Extraction and Application of Novel Eco-friendlyNatural Dye Obtained from Leaves of Sanamicky onSilk Fabric

摘要

Sanamicky plant as a source of natural dye was used to dye silk fabrics; this plant has not been exploited as natural dye by far. Optimization of natural dye extraction from sanamicky leaves with respect to dye bath concentration to aid exhaustion was done. The effect of changed dye bath concentration on the reflectance spectra was followed using spectrophotometer tool and CIE tristimulus values. The color parameters including L, a, and b values were determined. The data obtained indicated that the color parameters were highly affected by changing dye concentration by this new dye. The color fastness of fabric was very important aspect, as end use of fabrics depends on this property. The silk dyed fabric samples with sanamicky were evaluated for color yield, color difference and color fastness to light, washing, rubbing, light, perspiration and heat. Finding shows that the natural dye extracted from sanamicky leaves have good potential in textiles dyeing and can be exploited further. So, the present work gives the chance to produce different hues from a new traditional natural dye to improve the natural dyeing cultural heritage to meet the environmental future demands technology of high quality fantastic dyed pattern through an economical point of view. It was seen that pH of 3 and temperature of 80°C were the ones that produced the best results in and silk.
