Angled Ring Guide Assembly for Tubular Knit Torque and Skew Reduction

The patent changes the physical parameters of the yarn by using open-end yarn with lower twist multiple instead of ring-spun yarn with high twist multiple. This parameter change reduces the torque and skew in the knitted fabric while maintaining acceptable yarn strength through alternative yarn construction methods.

The patent employs composite yarn structures by combining different fiber types (cotton, polyester, rayon) in open-end yarn construction. This allows the yarn to achieve necessary strength through fiber interlocking and blending rather than relying solely on high twist, thereby reducing torque and skew in the final fabric.

The patent applies preliminary action by incorporating torque-reducing mechanisms during the knitting process itself, such as using specific needle configurations, yarn feed angles, and tension settings that prevent excessive torque development before the fabric even leaves the machine. This preliminary control maintains wale alignment while preventing subsequent skew during washing.

The patent converts the natural spiral tendency of knitted fabric into a benefit by deliberately designing the knitting process to create a controlled, minimal spiral that actually stabilizes the fabric structure. Rather than fighting the spiral tendency, the process harnesses it to create a self-stabilizing fabric that resists torque and skew during subsequent washing and drying.
