Study of fiber packing density of lyocell ring-spun yarns

Abstract

The study of yarn structure and related yarn properties has been the subject of much research. However, the study of the fiber packing density, which has practical significance for a number of yarns and their characteristics, has been limited to circular yarns because of the disordered yarn structure. In this paper, the fiber packing density of lyocell ring-spun yarns is determined with the image analysis method. This method does not have any limitation with regard to the fiber cross-sectional shape. The effect of yarn count, twist factor, spindle speed, traveler weight and front roller diameter on the fiber packing density in the yarn cross-section is analyzed. The results of this paper and the data published in other scientific works are in good agreement. © 2011 The Textile Institute.
