Production of torque-free singles ring yarns

The concept of a new direct approach to reducing yarn residual torque in ring-spun yarns, called Torque-free Singles (TFS) ring-spinning is introduced. Its incorporation into the ring spinning process without the need of an additional step is seen as its main advantage. It also requires only the attachment of a modification device to a conventional ring frame. The operating principle of TFS ring spinning is demonstrated. The efficiency of the modification process can be monitored by measuring the 'wet snarling' properties of the modified yarns produced. The modified yarn's achievement of a 38% reduction in spirality of a circular knit fabric as compared to its ring-spun counterpart is noted.
