Abstract
The fiber leading end density in the blended sliver composed of long and short fibers was measured and cross-sectional number of fibers was obtained by using sliver diagram. The sliver structure was analyzed along the sliver axis. Subsequently, the influence of various drafting conditions on the sliver structure was also examined. The results obtained are as follows: (1) Variations in the fiber leading end density of short and long fibers in the blended sliver showed a similar tendency along the sliver axis. In all regions along the he sliver sliver axis, variation in the fiber leading end density of the short fiber component is larger than that of the long fiber component. (2) In the blended sliver composed of long and short fibers, there are a large number of short fibers in the region where the sliver gets thicker. On the other hand, there are a large number of long fibers in the region where it gets thinner. This tendency gets more and more noticeable with an increase in draft ratio and roller gauge. (3) The correlation coefficient of the cross-sectional number of long and short fibers increases in accordance with draft ratio and roller gauge. The phase of short fibers advances a little more than that of long fibers.
