A general-purpose image processing analyzer was used to evaluate the blend irregularity in sliver by mean and standard deviation of detected blend ratio, which was obtained from the brightness of the image. The image of the black and white blended sliver was taken with a CCD camera.<BR>The influence of number of gilling, fiber length, blending system and feeding direction on the blend irregularitywas discussed. In sliver blending, as the number of gilling is increased, the blend irregularity is remarkably reduced. In stock blending process, the blend irregularity is small and it shows nearly the same value irrespective of number of gilling. This fact indicates that the sufficiently blend has been obtained in the stock blending process. In sliver blending process, the sliver composed of fibers with the same length shows better blending than that of different length fibers. In reverse direction feeding, the blend irregularity of sliver is better than that of the forward direction feeding.
