Comparative Evaluation of Yarn Hairiness by Different Methods

Abstract

Using a rapid yarn hairiness tester, the Shirley yarn hairiness meter, this work has confirmed that for cotton yarns, the statistical distribution of the number of protruding ends of different lengths is exponential. The study indicates that, compared to the other hair length settings available on the hairiness meter, the recommended 3 mm hair length is suitable and advantageous. Further there is a high correlation between the Shirley hairiness meter and two other hairiness indices, the modified Jedryka and the Digital fibrograph, considered in this work.
