| Abstract: | The effect of dye conc., electrolyte (common salt) conc., dyeing time and dyeing temperature on the dyeing of jute fibres with direct dyes, viz. Congo Red, Titan YelIow, Fast Orange PRS, Durazol Red and Direct YeIlow 29, has been studied. The dye absorption increases with increase in electrolyte conc., dyeing time or dyeing temperature and decreases with increase in dye cone. In some cases, higher temperature decreases the dye absorption. The colour of dyed and modified jute fibres fades on exposure to sunlight, washing with soap solution and acid and alkali spottings. A mixture of 2% potassium bichromate, 2.5% blue vitriol and 3% of 30% acetic acid has been found to be effective in preventing the colour of Titan Yellow on the dyed fibres, but it does not prevent the strength loss of direct dyed jute fibres. |
