摘要

A method for the manufacture of a bulky yarn with regular constrictions, characterized in that the yarn is subjected to forced oscillation between two fixed points under the action of a gas flowing perpendicularly to the running direction of the yarn, passing through the yarn twice in each period of oscillation the gas jet, forming a constriction, and being conducted to the treatment zone with a velocity, which is 5 to 50%, preferably 10 to 30%, above the winding speed.
