    摘要: A thermally stable meltblown fibrous web, including a plurality of meltblown multilayer fibers, in which at least some of the meltblown multilayer fibers each include at least one primary layer that includes a primary polymer that is slow-crystallizing with a Tm of at least about 200° C., and at least one secondary layer that includes a secondary polymer that is fast-crystallizing with a Tm of at least about 200° C.
