Abstract
A bi-component friction disc for imparting false twist to yarn to texture the yarn comprising an inner surface having a first portion of ceramic material surrounded by a second portion of polyurethane or rubber. Typically, one of these discs is installed on each end of a hollow tube, and two sets of tubes and discs are used in order to allow the yarn being textured to make four passes over the discs to impart the false twist.
