dc.description.abstractTorsional rigidity as well as torsional and tensile moduli of cotton was determined before and after crosslinking with formaldehyde (HCHO) and dimethylol dihydroxyethyleneurea (DMDHEU). The single fibre torsional pendulum method was adopted for determining the torsional properties, while the tensile load-extension curve obtained on the Instron was used for finding the tensile modulus. The tests were carried out in both conditioned (65% RH) and wet states. While the crosslinking in DMDHEU resulted in considerable increase in torsional rigidity, no such change seemed to accompany HCHO treatment. Torsional modulus did not change with HCHO treatment, but showed an apparent fall as a result of DMDHEU treatment, when this modulus was calculated on the basis of the increased cross-sectional area of the modified fibre. However, if the dimensional change is ignored and the cross-sectional area of the untreated fibre is used in the calculations, this modulus shows an increase. With both the treatments, the tensile modulus is found to register a fall. The results are discussed in the light of known ideas on fibre structure and deformation mechanism.en_US
