Abstract
An auxiliary nozzle for a loom, such as an air jet loom within a shuttleless loom, jets pressurized gas in order to prevent stall of weft inserted into warp shedding. At least a tip portion of an auxiliary nozzle body is formed of ceramics material having a very small integrally-molded surface roughness of 0.5 .mu.m or less and having characteristics of high toughness and high strength whereby occurrence of flaws in warp can be minimized and woven fabric of high quality can be obtained. Particularly, by employment of particular zirconia-type ceramics, the moldability, processing properties for drilling and wear resistance can be improved.
