ABSTRACT:
Apparatus for manufacturing a bulky textured yarn from a thermoplastic multifilament yarn by applying a pressurized heated fluid in a condition of automatically controlling the operating parameters of the texturing operation. During the steady operational condition of manufacturing the bulky textured yarn, the yarn tension is continuously detected in a drafting zone between a texturing device and a winding device, and the operating characteristics, such as surface temperature of the heating roller and, temperature of the pressurized heated fluid supplied to the texturing device, which affect the shrinkage of the processing yarn passing through the texturing device, are automatically adjusted so as to control the yarn tension in the drafting zone. To eliminate the causes which degrade the dyeability of the textured yarn produced in a period of carrying out a threading operation through the texturing device, the heating roller is preheated at a temperature higher than the set temperature thereof in the period of carrying out the steady continuous operation of the texturing device, and the set temperature of the heating roller is gradually lowered to that utilized during steady continuous operation, for a short time, for example 60 seconds.
