| Abstract: | The feasibility of combination process of jute degumming and bleaching with alkali-hydrogen peroxide in one-step-one-bath was discussed.The combination process basically has the similar function as the traditional two-step-two-bath method.The factors such as hydrogen peroxide concentration.CBI concentration, sodium hydroxide concentration, treatment time and temperature were studied respectively, and then an orthogonal experiment was designed to study the interactions among the hydrogen peroxide concentration, CBI concentration, sodium hydroxide concentration.After the designed experiments, the optimum treatment conditions were obtained as follows: hydrogen peroxide of 12 g/L, sodium hydroxide of 4 g/L, CBI of 4 g/L, JFC of 1 g/L, treatment time of 60 min and temperature of 75℃ |
