APPARATUS FOR FLUID TREATMENT OF FIBER BUNDLE

摘要

PURPOSE:To obtain the titled yarn having high strength and similar appearance to natural leather string, by arranging the first high-pressure liquid ejection nozzle train opened to the fiber bundle-passing hole and the other high -pressure liquid ejection nozzle train in a manner to have staggered phase along the circumferential direction of the fiber bundle-passing hole. CONSTITUTION:A plural rows of liquid ejection nozzles 5 are arranged along the direction of the fiber bundle-passing hole 7, and each raw is furnished with plural liquid ejection nozzles along the circumferential direction of the inner wall of the fiber bundle-passing hole 7. Each of the liquid ejection nozzles of the first liquid ejection nozzle train and each of the liquid ejection nozzles of the other liquid ejection nozzle train are arranged in a manner to have staggered phase with each other along the circumferential direction of the fiber bundle-passing hole 7. Water jets are made to collide with the circumference of the untwisted fiber bundle to obtain a string-like particular intertwined yarn.
