Polymer alloys including two or more components with differing melting points, filaments made thereof, and fabrics made therefrom

A synthetic filament formed from first and second compatible polymers. The first polymer has a first, higher melting temperature melting point and the second polymer has a second, lower temperature melting point that is at least 5° C. lower. The polymers are mixed and extruded to form a filament that has two distinct melting points so that the filament remains stable and can be heat set at a temperature less than the first high temperature. A woven textile is also provided which incorporates the filaments in at least some of the machine direction and cross direction yarns.
