Abstract
Fancy polyester based yarns are disclosed, wherein polybutylene terephthalate yarns comprise one or more filaments having irregular diameters, substantially constant crystallinity over the whole length of the filament, and a Young's modulus of less than 300 g/tex. These yarns are useful in textile applications wherein great pliability is required, such as for imitation silk fabrics, dress trimmings, and furniture fabrics.
