Abstract:

A method of bulking and heat-setting a moving, continuous length of twisted thermoplastic yarn. The method includes the steps of saturating the yarn with a dielectric fluid contained in a fluid saturation station. The yarn is then moved downstream from the saturation station to an electromagnetic heating chamber for heating the yarn using electromagnetic radiation. Simultaneously in the heating chamber, the yarn is bulked to add size and texture and the twist permanently heat-set. The twisted and bulked yarn is then collected in a collection station located downstream of the heating chamber.
