The dyed fibre showed poor to good fastness to light, very good to excellent fastness to rubbing, and poor to good to very good fastness to washing. The dyed fibres on exposure to bright sunlight or a light source of suitable wavelength showed a very good photochromic effect giving various shades. When the fibres were/removed from sunlight the colour returned to the original shade. The duration required for this return depended on intensity of incident light, ambient temperature and moisture content of fabric.</span> Page(s): 100-103 1986-06-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/32865 Title: Effect of Pre-heat-setting on Colour of Polyester Fabrics Dyed with a Disperse Dye Authors: Jahagirdar, C J; Venkatakrishnan, S Abstract: <span style="font-size:11.0pt;font-family:" calibri","sans-serif";="" mso-ascii-theme-font:minor-latin;mso-fareast-font-family:"times="" new="" roman";="" mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:minor-latin;="" mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;mso-fareast-language:="" en-us;mso-bidi-language:ar-sa"="">The effect of pre-heat-setting, at different temperatures and durations, of polyester fabrics dyed with a disperse dye (Dispersol Red B-3B) on dye uptake. dye penetration and the final colour of the fabric was studied. Variation in dye uptake was due to the variation in tension developed during heat-setting and structural changes. Colour measurement was found useful for predicting the optimum temperature duration of heat treatment and limits of variation tolerable for heat-setting a particular fabric with a particular dye. A new method is suggested for predicting the dye uptake from Δ <i>E </i>(total colour difference from the standard white).</span> Page(s): 94-99 1986-06-01T00:00:00Z
