Abstract (en)
[origin: WO2015199998A1] 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.
