Jute is a biodegradable natural fibre with advantages as high tensile strength, breaking twist and excellent luster. Due to the improvement of people's living standards and need for environmental protection, the demand of natural biodegradable and eco-friendly fibres is rising worldwide day by day. Jute fibre is composed of small units of cellulose surrounded and cemented together by lignin and hemi-cellulose. The low cellulose content, coarseness, stiffness, low extensibility, low grip performance and some other disadvantages seriously restrict the raw jute fibre from spinning. So a series of wet chemical processing sequences are needed to improve the spinnability of jute fibre. The experiment was conducted in Textile Physics Division of Bangladesh Jute Research Institute during 2012 and 2013. For the improvement of spinning properties of jute fibre some chemical treatment were done. For modification of jute fibre, modifying factor such as softening agent concentration, NaoH concentration, time, and Material Liquor Ratio (MLR) were optimized as NaoH: 15 g/l. Softening agent: 2.5 g/l, time:20 minutes and MLR-1:10, after alkali and softening treatment. From the study it was found that the breaking twist means spin ability has increased than that of raw jute fibre. Furthermore the modified jute fibre had soft feeling than raw jute fibre. The modified jute fibre should be blend with cotton for jute cotton blended yarn production in spinning technology.
