Evaluation of improvements in yarn quality with new ring spinning frame

Eric Hequet, Dean Etheridge, William Cole

Abstract


Since 1996, the ITC has had a Zinser 330 HS ring-spinning frame. This new-generation of ring spinning technology runs at about twice the speed of the remaining, old Saco Lowell SF-3H frames in the ring-spinning laboratory. Furthermore, the improved geometry and other features of the Zinser 330 HS make possible a higher quality of yarn than is possible with the old technology. This report was prepared to reveal: l the extent of yarn quality improvements with this new technology; l the extent of interactions among key variables of interest to fiber and textile producers; and l the nature of relationships between fiber property variables and yarn quality variables on the two ring spinning frames being compared.
