This study was conducted to sustain the eco-friendly approach for bleaching ofKydia calycinafibres. TheKydia calycinafibres were extracted from the young shoots ofKydia calycinaplant through water retting and then the extracted fibres were scoured with pectinase enzyme. After that, the scouredKydia calycinafibres were bleached with three different methods. Among them, the best bleaching method was selected on the basis of tenacity, elongation, fineness, fibre length, weight loss and whiteness index. The concentration of sodium perborate, concentration of TAED, time and temperature of selected bleaching method were optimised using SAS software. At optimisation stage, tenacity, elongation, fineness and whiteness index of bleached fibres were tested. The results indicated that TAED activated sodium perborate showed better tenacity (3.81 g/d), elongation (2.09 %), fineness (22.92 denier) and maximum whiteness index (68.67) at optimised variables including concentration of sodium hydroxide (5 g/l), concentration of TAED (3 g/l), time (60 min) and temperature (500C).
