ABSTRACT:
A traveling yarn is introduced into a yarn treatment chamber, such as a texturing device, wherein essentially standard treatment temperatures are being employed, the yarn traveling at standard speeds and temperatures for the treatment process carried out in the treatment chamber. The yarn is caused to pass through, out of, and away from the yarn treatment chamber.
This is accomplished by first capturing the traveling yarn and positioning the captured traveling yarn in front of the inlet orifice of the yarn treatment chamber at a tension of 0.025 gram/dtex to 0.35 gram/dtex. Then the captured traveling yarn is cut and simultaneously directed into and through the yarn treatment chamber by means of an external propelling fluid. Finally, the treated yarn is conveyed away from the yarn treatment chamber.
