PROCESS FOR MAKING FIBER-ON-END MATERIALS

摘要

Processes for making fiber-on-end materials from multicomponent fibers and hollow fibers are provided. The fibers are arranged parallel to each other and continuously thermally fused into a ribbon or fabric, which in turn is thermally fused into a fully consolidated block of material that is skived to produce membranes or capillary arrays having narrow, well-defined pore size distributions. The skived materials are particularly useful in filtration and protective clothing applications.
