The present study was conducted to evaluate changes occurring in the comfort properties during the BIOPOLISHING of cotton fabric. The study was carried out on 100% grey cotton fabrics of three different fabric weight viz. light, medium and heavy weight. Grey cloths were given pre-treatments prior to bio polishing. Pre-treatments included desizing, scouring and bleaching. Biopolished fabrics were analyzed for their constructional and comfort properties. Not much variation was shown in all the constructional properties but porosity showed marginal increase. Similarly, comfort properties, only in case of heavy weight fabrics showed higher comfort values. [ABSTRACT FROM AUTHOR]

The article presents a study which applied poinsettia leaves for dyeing silk fabric. Textile color alteration is a common problem. When subjected to specific conditions, for instance washing, colored textiles usually show alteration in hue, value and intensity. Colored textile when mixed readily transfer color to non-colored textiles and bleeding hasten the alteration of colored textile. Colorfastness defines the resistance of colored textiles to changes when subjected to a set of conditions. This study tests the colorfastness ability of poinsettia leaves.

The article provides information on the use of Poinsettia to create a wide range of colours for silk dyeing. Silk fabric was used for standardization of dye procedure. Degumming was done to remove impurities, if otherwise interfere with the absorption of dye. Dye concentration was optimized by extracting five different concentration of dye. Five dye solution of Poinsettia were prepared with optimized dyeing concentration of dye material and extraction time. Simultaneously mordanting and dyeing was used to find out the optimum concentration of mordant, as it is least time consuming method. Acidic, alkaline and aqueous medium was used for extraction of dye. Acidic medium was selected as it gave good shades on silk. The percentage absorption of silk increased with increase in the concentration of Poinsettia leaves dye. The optimized concentration of dye, extraction time, dyeing time and concentration of mordants were used for each method of mordanting. Simultaneous mordanting and dyeing was preferred for hards, amla and alum and post mordanting was preferred for pomogranate, copper sulphate and ferrous sulphate for Poinsettia dye.
