Beschreibung
Zusammenfassung:	A nonwoven article includes a plurality of polycrystalline, aluminosilicate ceramic filaments entangled to form a cohesive nonwoven mat. Each of the aluminosilicate ceramic filaments in the mat has an average diameter of less than about 2 microns (µm), and the aluminosilicate ceramic filaments include an average of about 15 wt% to about 80 wt% crystalline mullite. La présente invention concerne un article non tissé comprenant une pluralité de filaments de céramique d'aluminosilicate polycristallin entremêlés qui forment un tapis non tissé cohésif. Chacun des filaments de céramique d'aluminosilicate dans le tapis a un diamètre moyen inférieur à environ 2 microns (µm), et les filaments de céramique d'aluminosilicate comprenant une moyenne d'environ 15 % en poids à environ 80 % en poids de mullite cristalline.
