摘要： Methods for preparing composite non-woven fibers-in-fibers, otherwise referred to as composite polymeric fibers having an island-in-sea morphology, are described. The composite polymeric fibers may be prepared by a method that includes melt-blowing a blend of a first polymer and an immiscible second polymer to form the composite polymer fibers. The first polymer forms a matrix that surrounds the second polymer. Typically, the second polymer forms nanofibers within the matrix of the first polymer. The composite polymeric fiber may be treated with a solvent that selectively dissolves the matrix of the composite polymeric fiber and that does not dissolve the nanofibers of the composite polymeric fiber, and the nanofibers then may be collected for further treatment or use.

摘要： A filter media is described that employs multicomponent fiber material to form the filter media. The multicomponent fiber material is composed of two or more materials at least one of which is soluable in the application fluid that flows through and is filtered by the filter media to release additive(s) in a controlled manner into the application fluid. The additive(s) releases slowly throughout the filter application life.
