摘要：
The friction texturized polyester filament yarn has a titer of 400 to 600 dtex and a crimpability of at least 45% and can be provided with at least 60 slubs/m. The method of making this friction texturized polyester filament yarn comprises texturizing a flat yarn with a titer of 400 to 600 dtex at a rate of at least 350 m/min and a yarn tension ratio, F2/F1, less than one via a squeezing twister. A set yarn can be made from the friction texturized polyester yarn with the titer of 400 to 600 dtex by heating.
