|Title:||Fineness Characteristics of Jute Fibres in Sliver at Different Preparing Stages and in Yarn|
|Authors:||Banerjee, B L|
|Abstract:||The fineness-length relationship and the average tex of fibres in hessian quality slivers at finisher card, and first, second and finisher drawing stages, and in yarns have been studied separately for the three broad categories of fibres termed unfolded folded and root (i.e. those originating from the under-retted root ends or defective parts of raw jute reeds). The tex value of unfolded and folded fibres increases almost linearly with their length over the length range 5 to 30 cm, and there seems to be no appreciable change in fineness of fibres over this range at the drawing and spinning stages. In the case of root fibres, however there is no clear trend in fineness-length relationship. The average tex of fibres is reduced from finisher card sliver to yarn, the reduction being more pronounced at the first drawing stage. It is suggested that this is due to the rupturing and splitting of long fibres (> 30 cm) which are generally more branchy and coarser than the normal ones. The number of unfolded fibres increases but that of folded fibres decreases from finisher card sliver to yarn. The number of root fibres remains practically unaltered at all the stages.|
