Cohesion Phenomena in Cotton Rovings and Yarns

Abstract

In the present work, cohesion phenomena of a general character are studied in cotton rovings and yarns. The cohesion is expressed as a coefficient of minimum twist of cohesion, and the following are considered throughout the work: (a) influence of testing conditions on the cohesion of rovings and yarns, (b) influence of fiber characteristics on cohesion. Finally, on the basis of data of the cohesion test, the strength of cotton rovings is also considered. In this first part of the work, commercial yarns and rovings have been used.
