摘要： A rigid core for a textile yarn package particularly for dyeing is cylindrical in shape, corrugated over the whole outer peripheral surface corresponding to the package, and has a part situated at one end which is provided with a groove, incorporating perforations of a maximum diameter of 2 millimeters, which is intended for forming a yarn reserve, a central part perforated with tapered orifices, wider at the outer surface than the inner, with an angle of taper, relative to the axis of the respective orifice, being between 2.degree. and 80.degree., preferably between 20.degree. and 70.degree., and two interengably shaped ends to permit the fluid-tight nesting of the cores on each other during the dyeing.The method of using such a yarn package in which a textured continuous polyester yarn is reeled at a speed of between 400 and 1,000 m/min.
