Abstract
Quantitative estimation of load bearing capacity of parallel fibre assembly has been made by applying transverse pressure on them with the help of an attachment while they are strained longitudinally by the tensile strength tester. Tenacity of parallel fibre assembly increases with the increase in transverse pressure applied by the compression blocks (attachment), the rate of increase is found to be high initially up to 80 g/cm2 applied pressure and thereafter, notable reduction in the rate of increase in tenacity is observed. These results confirm the assumption that in case of Dref-III yarns the tensile force developed in the parallel bundle of core fibres is due to the compressive force generated by the sheath fibres. Required sheath-fibre content for generation of a given transverse pressure has been calculated by solving the regression equations for sheath fibre content and applied transverse pressure with tenacity.
