Needle of jetting nozzle for water jet loom

Abstract

The present invention relates to a needle of a jetting nozzle for a water jet loom. In the needle of the jetting nozzle for the water jet loom, a protruding part (8) having an inclined surface (10) and an inclined cross-section part (11) is formed at a side of a needle (6) which is located in a first water storage part (5a) in order to rectify water in an unstable state which is introduced to a water storage part of an injection nozzle, whereby the water in an unstable state, while going through the inclined surface (10) and the inclined cross-section part (11), passes through a waterway (12) and is rectified to be injected through an outlet (24) in a stable state. Thus, the needle has effects of improving quality of fabric according to diffusion reducing of the injected water (30) and concentration increasing and of saving costs.

Description

technical field [0001] The present invention relates to a spray needle of a nozzle for a water jet loom. It relates to reducing the spread of the spray water sprayed from the nozzle and improving the bundling property, so that the interference of the spray water on the warp yarn can be reduced, and the traction force of the weft yarn can be increased to achieve more stable threading. latitude The spray needle of the water jet loom with the nozzle. Background technique [0002] In general, a water jet loom weaves fabrics by introducing weft yarns between warp yarns that are open up and down by using jet water jetted from nozzles. [0003] The general weft insertion principle of the water jet loom is that the intermittently pressurized water in the pump is intermittently ejected from the nozzle through the water supply pipe. [0004] The nozzle is roughly divided into a body part and a needle part, such as Figure 8 As shown, the weft yarn that passes through the spray need...

AI Technical Summary

Problems solved by technology

[0007] In order to solve various problems such as warp lengthening, breakage and weft insertion instability caused by the diffusion of jet water and the resulting decrease in the binding force, it is necessary to increase the size of the upper and lower openings of the warp and increase the size of the jet. Water Volume and Jet Water Pressure

[0008] However, when the amount of upper and lower openings of the warp yarns, the amount of sprayed water, and the sprayed water pressure are increased, the resulting problems are degradation of the quality of the fabric, premature aging of related mechanisms caused by excessive use of sprayed water, and increased water pressure.
