The fibres extracted mechanically (raspador machine) from pseudostem of banana plant varieties Grand Naine and Ney Poovan were subjected to wet processing treatments such as scouring and bleaching. Further the physical parameters i.e. fibre weight loss, length, strength, elongation and fineness were assessed. The results revealed that significant increase in weight loss was observed with increasing concentrations of the wet processing liquors. Irrespective of the varieties, the length of the fibre gradually reduced. Fibres scoured with 1 per cent NaOH concentration exhibited improvement in the fibre strength in both the varieties; whereas 2, 3 and 4 per cent NaOH concentration reduced the strength. Similarly, the strength significantly decreased on scouring + bleaching and direct bleaching treatments. The elongation percentage decreased significantly with increase in NaOH and H2O2 concentrations. Maximum fineness was found in fibres treated with 4 per cent NaOH concentrations and 2 per cent H2O2 concentration. Manually spun yarn was used to prepare value added utility products using braiding and crocheting techniques. Fashion accessories like key chain, belt, hand bag, basket, mobile cover and household utility articles are table mat-I (square), table mat-II (circular), tea coasters, pen/spoon holder, wall mate-I and wall mate-II.EnglishThesis
