The description of the textile friction ceramic disc
Advanced ceramic melt spinning parts, including traverse guides, pigtail guides, air-jet nozzle, spin finish applicators have been extensively using the polymer fiber production. With our veteran knowledge for materials and growing experience for the design of the physical application in the production, we can design the contact surface with yarn, thread to be the ideal state with the diamond polishing finish.
We offer a number of ceramic yarn guides for thread guides, yarn forming, and yarn modification via different shaping methods in different technical raw materials as per customers' needs.
All these ceramic yarn guides are designed for use in processes at low yarn tensions with no damage. It helps decrease and maintain times and improve production efficiency greatly.
