Abstract
Described herein are textile fiber-working units and methods for preparing them. These units have at least one layer made of a mixture of a polyamide, a crosslinked acrylonitrilebutadiene rubber, a plasticizer and a crosslinking agent. This layer forms a ring and has an outer fiber-working surface which forms an endless path for processing fibers. The units are made by combining the ingredients to form a uniform blend which is then worked into a shape, heated to crosslink the rubber, and then producing the fiber-working unit using appropriate finishing techniques such as cutting, grinding, and polishing.
