A Study of the Hairiness of Cotton Yarns Part I: Effect of Fiber and Yarn Factors

A combmation of singeing and microscopic techniques has been adopted in the present study to get an insight into the length, nature, and distribution of protruding fibers causing hairmess in yarns. Alter examining various indices, a stutable method of expressing hairmess as the loss in weight on singeing per unit weight of varn has been adopted. Relationships between yarn hairmess and various fiber properties have been investigated in detail, and the factors that influence the preferential protrusion of fiber ends towards the yarn surface are studied by a tracer fiber technique. The results indicate that torsional and flexural rigidity. fiber length, and fineness of cottons are significantly correlated with yarn hairmess. Further, the length of protruding fiber ends and loops is mfluenced not only by the fiber properties of the cottons used but also by processing techniques and factois of varn geometry.
