Abstract

The physical characteristics of hemp fibre were examined in terms of heat treatments and chemical treatments. Hemp fibres with hydrochloric acid and glyoxal for 2 hours. The effects of alkaline as well as formaldehyde therapy on elongation and tensile force at breaking were thoroughly investigated. Hemp's tensile modulus increased for the first five days of ageing at 50 °C before dropping. Heat complexation of the viscose in the fibre may have increased tensile properties, but pyrolysis due to glucose crosslinks decreased tensile. Tensile strength increased and break elongation decreased in nutrient specimens. Contaminants like paraffin as well as fat residue were removed from coconut fibre by interacting with the strongly basic solutions, which increased the fiber's strength. The cross linkage of viscose to fumaric acid in the fibre reduces flexibility while in use. Experiments were used to investigate the changes in morphology due to chemical treatments. Because of structural rigidity, NaOH and glyoxal can be successfully used to change hemp fibre with outstanding physical properties.
