Yarn and fabric strength is one of the most important parameters to predict the uses of the end product. Fabric strength mostly depends on yarn strength and yarn strength is prejudiced by fibre strength or fibre properties. Crimp is one of the essential parameter that influences the fibre properties. In this research, crimp box and gear crimp methods were used to introduce crimp into jute fibre. It was found that crimps were irregular in size, shape and number produced from crimp box method. On the other hand, crimps produced from gear crimp method were comparatively regular in size, shape and number. Yarn and fabric strength tests were carried out according to testing standard. It was revealed that yarn strength and elongation at break of gear crimp method were higher than that of crimp box method. Apart from this, fabric strength and elongation were also improved for a regular and increased number of crimps for gear crimp method.
