ABSTRACT:
A continuous synthetic filament yarn is processed by crimping, entangling, and straightening the yarn. The yarn is straightened by heating under tension, resulting in a yarn that can be used in its straightened form and later bulked by a subsequent process such as dyeing, boiling, heating, etc. The length of a yarn plug formed by crimping is controlled by controlling the temperature of the yarn.
