ABSTRACT:
An improved high speed process for texturing continuous filament yarn is provided wherein the improvement comprises cooling the yarn, subsequent to texturing and prior to applying tension, by contact for at least 4 milliseconds with a curved surface at a temperature of -29.degree. to 2.degree. C. and an RMS of up to 10, frictional forces creating a yarn tension of 0.036 to 0.45 gram per denier per end at the surface. Apparatus is also provided for cooling the continuous filament yarn subsequent to texturing and prior to applying tension. The apparatus comprises a curved surface having a minimum length for yarn contact of 7.6 cm, an RMS of up to 10 and a temperature of -29.degree. to 2.degree. C. Textured yarn brought into contact with the surface for at least 4 milliseconds at a yarn tension of 0.036 to 0.045 gram per denier per end is cooled to increase yarn stability and prevent pullout of yarn texture.
