Abstract | A composite polymeric material is provided that may be used to construct an abrasion resistant layer or sheet such as an abrasion resistant meltblown layer. Desirably, the composite polymeric material comprises blends of syndiotactic and isotactic polypropylene with ferroelectric materials. The composite polymeric material is particularly useful for constructing a filter media comprising an abrasion resistant fine fiber layer such as a nonwoven layer. The composite polymeric material of the present invention also allows for electret treatment to improve its filtration characteristics.
L'invention concerne un matériau polymère composite qui peut être utilisé pour construire une couche ou feuille résistante à l'abrasion, telle qu'une couche obtenue par fusion-soufflage et résistante à l'abrasion. De façon souhaitable, le matériau polymère composite comprend des mélanges de polypropylène syndiotactique et isotactique avec des matériaux ferroélectriques. Le matériau polymère composite est particulièrement utile pour construire un milieu filtre comprenant une couche de fines fibres résistante à l'abrasion, telle qu'une couche non tissée. Le matériau polymère composite de la présente invention permet également un traitement d'électret pour améliorer ses caractéristiques de filtration. |
