    The Fiber leading end density in the blended sliver composed of long and short fibers was measured and crosssectional 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 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 noticable 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.

  • Relation between Dynamic Friction and Shrinkage of Plasma-treated Wool

    In order to investigate the relationship between dynamic friction coefficients of plasma-treated wool and its shrinkage, we have made the apparatus for the friction measurements of single wool fiber in water. The effects of plasma treatment on the dynamic friction coefficient of wool and shrikage were studied using the apparatus. When wool is treated by plasma, chemical modification and etching occur. Since these surface changes influence differently the dynamic friction coefficient, the coefficient itself is not closely related to the shrinkage. However it was found that the difference between with-scale friction and against-scale one, that is scaliness, is correlated to the shrinkage. Also the situation of scale in water can be assumed from the comparison of scaliness in air with that in water.

  • Needle Deflection and Sewability on Sewing Machine

    It is established that in sewing operation, a needle could be deflected by factor like sewn fabric structure. Empirically, however, this deflection is considered to be closely related to sewability, but without defining the proper correlation they may have. A series of studies are, therefore, undertaken to find out the correlation between sewability and needle deflection in sewing operation. The present paper is aimed at a proposed method for evaluating the needle deflection. In the method, the deflecting force is measured by two gauges attached to the lateral surfaces of a needle shank, and then the deflection is estimated by using a simple needle shape. Some model studies are carried out on synthetic paper and cotton fabrics, and their results are presented.
