Abstract:
1. A bicomponent fiber comprising first and second polymer components present in distinct portions of the cross section of the bicomponent fiber, wherein the first polymer component of the bicomponent fiber is partially crystalline and serves as the matrix component of the bicomponent fiber and the second polymer component of the bicomponent fiber is amorphous and serves as the binder component of the bicomponent fiber, and wherein an area-bonded nonwoven comprising the bicomponent fiber exhibits a single melting peak as evidenced by a differential scanning calorimetry (DSC) trace, wherein the bicomponent fiber comprises from 75% to 98% of the first polymer component and from 2% to 25% of the second polymer component, by weight of the bicomponent fiber.
