Studies on the Physico-mechanical Properties of the Modified Jute Fibre by Sulphonation Method

Nurul Islam, Mohammad Ali, M. Kamal Uddin, Khalil Ahmed and A.M. Sarwaruddin Chowdhury    

Abstract: Modification of jute fibre was due to sulphonation which were improved the physico-chemical and physico-mechanical properties of jute fibre. The change in chemical composition, morphological, geometrical structure, tensile properties and stress-strain characteristics were determined at different degree of sulphonation at optimal reaction conditions. The dimensional structure and mechanical properties of sulphonated jute fiber was studied. In sulphonation no damage and disintegration of the fibre cells were noticed except swelling of the secondary wall only and the fibre tenacity was not impaired. The sulphonation treatment in the optimal condition were improved the fineness in terms of linear density and developed flexibility, softness and compressibility of jute fibre. These values were measured in order to assess the textile importance of sulphonated jute fibre compared to cotton and other textile fibres for fine spinning. The stress-strain properties of the sulphonated fiber were much improved. The breaking extension of jute fibre was increased up to 3% with the degree of sulphonation against the initial value of 1%. The evaluation of these properties was regarded very significant towards improvement of spinnable characters and other textile performances of the sulphonated jute fibre.
