Title: Texturizing nozzle with a through duct for yarn for preparation of a curling yarn
Inventor: BERTSCH GOTTHILF
IPC: D02G1/16
Filed: 1997-02-14
Granted: 2002-02-21
Abstract: The present invention provides a method capable of enhancing the intensity of texturizing, in which the velocity of an air stream over Mach 2 can be obtained by means of a specific shape of a nozzle duct. The total aperture angle of the nozzle duct disposed immediately in front of the texturizing zone are designed to be bigger than that of the ideal Laval angle, and with an effective length which is preferably many times the narrowest diameter of the nozzle. Above all, this invention can improve the quality of the texture, which is surprising particularly under the circumstance that the productivity is high. The productivity can be increased to a range of from 600 to 1000 m/min and even higher. It is amazing that the present nozzle core can be so shaped that it can exhibit all the advantages of this invention, and be used as a replacement element for replacing the nozzle core of the existing art. The same can be applied to the texturizing head assembly, because the present invention is usable within the same outer geometric external dimension measurement and the same air pressure as well as the same air volume.
