ABSTRACT:
A process for treating a ply-twisted crimped multifilament yarn. The process involves adjusting the temperature and moisture content of the yarn prior to passing the yarn through a stuffer box which is essentially free of steam. Excess hot fluid is removed from the yarn, and the yarn's temperature is adjusted to a temperature in the range of about 40.degree. to 90.degree. C. before the yarn is passed through the stuffer box. The yarns may be used for making a textured saxony-type carpets having a tightly tailored surface texture.
