Oils and water absorption behavior of Biduri (Calotropis gigantea) fibers

This article reports on the oil and water absorption behavior of Biduri ( Calotropis gigantea ) fibres at room temperature. The material measured is a 100% raw material for Biduri (Calotropis gigantea) fibre, from 0.3 g to 1.5 g, and nonwoven structures made from 50/50, 60/40, 70/30, 80/20, and 90/10 mixture of Biduri and polyester. FTIR characterized the Biduri fibre, and the viscosity of used oil measured using Brookfield viscometer. The higher oils absorption at weight 0.3 g, 45.53 g/g, and water absorption at weight 0.3 g, 1.47 (g/g). The higher oil absorption at nonwoven structure showed at 90/10 composition, 42,86 g/g. It showed Biduri fibre is a natural absorbent that exhibits excellent hydrophobic and oleophilic properties.
