Abstract
A method for high speed melt spinning of binder fibers by melting a polymer that exhibits substantially no exothermic crystallization peak as measured by DSC when it is cooled to solidification from a molten state according to test A, spinning said polymer at a speed of greater than about 2000 meters per minute to form said binder fibers; and winding said binder fiber onto a spin bobbin.
