Beschreibung
Zusammenfassung: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 DEG C, and at least one secondary layer that includes a secondary polymer that is fast-crystallizing with a Tm of at least about 200 DEG C. 本发明提供了种热稳定熔喷纤维幅材，所述热稳定熔喷纤维幅材包含多个熔喷多层纤维，其中所述熔喷多层纤维中的至少些各自包含至少个包含主要聚合物的主要层，所述主要聚合物为缓慢结晶型聚合物且T为至少约200℃，以及至少个包含次要聚合物的次要层，所述次要聚合物为快速结晶型聚合物且T为至少约200℃。
