The description of ceramic eyelet guides
Alumina is a leading most popular technical ceramic material for ceramic yarn guides. In the application of yarn passaging, its extraordinary hardness, wear resistance, low friction coefficient, and anti-chemical performance are used fully. These outstanding characteristics greatly help the textile machinery to extend its service life, improve production efficiency, and decrease the breakage of yarn, thread, and wire in the productions.

Our state of the art forming processes include hot pressing, dry pressing. The ceramic body is very dense after high-temperature cured. The main type of textile ceramic spare parts includes ceramic eyelet guides, ceramic roller, traverse guide, ceramic pigtail guide, air-jet nozzle, friction disc, and so on. These textile ceramic parts can be made of the high purity of alumina, zirconia, and titania ceramics.
