Abstract
The physical properties of an elastane, i.e. spandex, filament may be selectively altered basically by stretching the filament to a selected degree while heating the filament to a selected temperature above its glass transition temperature to set the filament at a reduced denier and a reduced degree of elongation. The tenacity of the filament may increase or decrease depending upon variable parameters of the methodology. The method may be performed on a single elastane filament or simultaneously on multiple filaments, e.g., in a draw warping operation.
