摘要：

The effect of ambient temperature bleaching of jute fibre with hydrogen peroxide on yarn properties and dyeing behaviour has been studied and compared with that produced by conventional hot bleaching technique. The optimum duration for ambient temperature bleaching of jute fibres of both white and tossa varieties has been found to be 1.5 h. Spinning process causes around 30% loss in whiteness index of bleached fibre, and carding and spinning stages are mainly responsible for it. Yarns produced from both hot and ambient temperature bleached fibres using suitable bleaching recipes give remarkably higher tenacity and higher work of rupture than that of grey yarn. Dyeing of yam made from ambient temperature bleached fibres results in higher dye uptake and shows an upward trend in work of rupture. A suitable recipe for ambient temperature bleaching consisting of 50 gpl hydrogen peroxide, 15 gpl sodium hydroxide, 20 gpl sodium silicate and 2.5 gpl sodium persulphate is suggested to get better yarn property and dyeing behaviour.
