    Characterization of Yarn Diameter Measured by Different Systems

    This thesis work tries to establish ways of comparing yarn diameter measurement values obtained from different measuring systems particularly Uster Tester 4 and QQM 3 as attempts have been made in the past to try and correlate the results from these two instruments. The work will also try and further investigate the versatility of the D-Yarn program in analyzing yarn diameter (and its variations) data compared to other similar analyzing systems. Yarn diameter and its variations together with hairiness were measured and compared accordingly, using various instruments and systems and from there, conclusions were drawn as to the comparability (correlation) of the results from these instruments.
