Abstract
Mascarilla de respiración que comprende capas múl tiples que incluyen una capa que contiene partículas sorben tes permeables al aire entre capas que retienen partículas permeables al aire, siendo al menos una de las capas de dicha mascarilla de respiración una capa que retiene la forma, en la que la capa que contiene partículas tiene una forma generalmente semejante a una copa, caracterizada porque la capa que contiene partículas era estirable durante la conformación a dicha forma semejante a una copa sin desgarramiento o pérdida significativa de partículas, y al menos algunas de las fibras en la capa que contiene partículas son suficientemente adhesivas después de ser conformadas por sí mismas en una tela libre de partículas y enfriada a temperatura ambiente de tal manera que la tela se adherirá a sí misma.
