Abstract:
Most spandex polymers may be generally classified as polyether-polyurethane-polyurea block copolymers. They are composed of crystalline hard segments dispersed in a matrix of amorphous soft segments. The dynamic interplay between the soft and hard segments determines the stretch and recovery properties of the polymer. The many compositional variables and their effect on polymer properties as well as the spinning process and its effect on fiber properties will be briefly reviewed. Macro- and microscopic properties of spandex fiber will also be discussed.
