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.

Abstract: Non-stick protection can be given to the surfaces of thermoplastic material which has a tendency to become stuck to other thermoplastic surfaces during storage, especially during the heat of the summer months. By placing a film of (1) a salt selected from (a) a hydroxy alkyl sulfonate salt and (b) and alkyl sulfonate salt, and (2) an alkyl sulfate salt on the surface of the thermoplastic, sticking can be reduced or totally prevented.
