Description
Summary:An investigation is reported in which tops manufactured from batches of greasy wool varying widely in staple strength and the location of the zone of weakness were converted to yarn on the worsted system. The strength properties of the greasy wools were not related to the fibre breakage that occurred in producing yarn, nor did they significantly effect spinning breaks or yarn properties when spinning speed was similar to that used in commercial practice. At higher speed, however, variations in spinning efficiency and yarn properties were more closely related to the differences in Hauteur in the tops and therefore to the strength properties of the greasy wool.
