Webspirality on acrylic and cotton knitted fabrics is observed as twist liveliness. It is observed that the angle of spirality is decreasing on knitted fabrics, when yarns are fixed with vapor. At the same time by using two-ply yarns, the spirality is prevented, because the twist direction of the two-ply yarn is opposite to the twist of one-ply yarn. Webapparatus has made accurate and repeatable measurements of twist liveliness over a range of 100 % cotton ring spun yarn counts.

Direct Objective Measurement of Yarn-torque Level

WebAbstract Yarn residual torque or twist liveliness occurs when the twist is imparted to spin the fibers during yarn formation. It causes yarn snarling, which is an undesirable property … WebThe twist liveliness of false-twisted and set yarns depends on their structure and, in particular, on the properties of the helical parts of their filaments s. 1.1 Snarl The snarl is due to yarn torque and takes place dur ing the torsional buckling effect, where the yarn retires into itself and simultaneously is twisted in the opposite WebDraft International Standards adopted by the technical committees are circulated to the member bodies for voting.
