Abstract
A method for texturizing synthetic thermoplastic yarn in a bulking apparatus wherein a heated, dry gas is employed to convey a yarn into a bulking chamber to form a compact mass of yarn. The process is characterized in that an auxiliary gas is introduced into the bulking apparatus at a lower temperature than that of the heating gas to convey the yarn during start-up and/or shutdown of the apparatus to avoid over-heating and fusion of the yarn, and to thereby prevent plugging of the apparatus.
