Title:
AUXILIARY SUB-NOZZLE FOR FLUID JET TYPE LOOM AND PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/1989/004390
Kind Code:
A1
Abstract:
This invention relates to an auxiliary nozzle for a loom which jets a pressurized gas in order to prevent the slowdown of a weft to be crossed with warp and to a method of producing the same. At least the tip of an auxiliary nozzle body is composed of an integrally molded ceramic material having extremely small surface coarseness, high tenacity and high strength, which makes it possible to remarkably reduce the occurrence of damage to the warp and to obtain a high quality woven product. Particularly when zirconia ceramic is employed, the moldability and durability of the nozzle can be improved drastically. Further when partially stabilized zirconia is used as a matrix, the moldability, borability and wear resistance can be improved and a high precision auxiliary nozzle can be obtained.
