False-twister as a yarn formation factor in wrap spinning

Abstract

The aim of the research published in the paper was to study the role of the false-twister in the formation of wrap yarns on a hollow spindle machine. Three cases were investigated as follows: without use of false-twister, with single wrapping around the false-twister, and with double wrapping around the false-twister. Wrap yarn structure, geometrical characteristics, and mechanical properties were analyzed. The results obtained showed some discrepancies with former statements in literature, but demonstrated the significant importance of the false-twister for the morphology and properties of the plain wrap yarns.
