ABSTRACT:
The invention provides a voluminous, false twist texturized filament yarn having a great number of individual protruding filament ends; the filaments forming the filament yarn being of the same polyester raw material. The strength of such filament yarns must be of from 1.3 and 1.7 cN/dtex at a clamping length of 5 cm, and at a clamping length of 200 cm of less than 75% of the strength at 5 cm of clamping length, at least however of 0.8 cN/dtex, and the unevenness of the yarn must be less than 3 Uster %.
These filament yarns can be processed to web-like structures which correspond to webs made from staple fiber yarns obtained by secondary spinning with respect to their textile properties, their handle, drape and appearance, and which furthermore are distinguished by their low pilling.
