The structure of fiber tufts of a sliver consisting of equal length fibers has been analyzed and some uses have been found from the results.<BR>1) The evaluation of fiber distribution in the sliver can be attained by using the value of V (W<SUB>F</SUB> - W<SUB>B</SUB> / W<SUB>F</SUB> + W<SUB>B</SUB>), where W<SUB>F</SUB> and W<SUB>B</SUB> are weights of frontand back of half a tuft and V is the Variance.<BR>2) The begree of fiber hooking in the sliver is well presented by E (W<SUB>F</SUB> - W<SUB>B</SUB>/ W<SUB>F</SUB> + W) <SUB>B</SUB>, where E is the mean.<BR>3) The short fiber content R obtained from the staple diagram is related to R<SUB>I</SUB> or R<SUB>II</SUB> derived from the fiber tuft method by the following equations as R=12R<SUB>I</SUB> / 3 + 4R<SUB>I</SUB> and R = 3 R<SUB>III</SUB> . A good correlation between the theoretical and the observed values is found.
