Splash Resistant Facemask
There is provided a splash resistant facemask having two outer splash layers adjacent each other on a side away from a wearer, a filter layer and an inside layer. None of the layers contains a repellent treatment. The facemask can pass a fluid splash resistance test, e.g. ASTM F-1862-05, wherein fluid is directed at the mask at a pressure of 160 mmHg.
1 . A fluid resistant face mask comprising two outer splash layers adjacent each other on a side away from a wearer, a filter layer and an inside layer wherein none of the layers has a repellent treatment and wherein said mask passes a test of splash resistance conducted at a pressure of 160 mmHg.
2 . The mask of claim 1 wherein the splash layers have a combined basis weight of at least 1.4 osy and where the second (inner) splash layer has an air permeability value of greater than 250 CFM/Ft 2 .
3 . The mask of claim 1 wherein the filter layer has an air permeability value greater than 40 CFM/Ft 2 .
4 . The mask of claim 1 having an air permeability of at least 30 CFM/Ft 2 .
5 . The mask of claim 1 wherein said outermost splash layer has a drape stiffness above 3.5.
6 . The mask of claim 1 wherein said outermost splash layer has a drape stiffness above 4.0.
7 . The mask of claim 1 wherein said outermost splash layer has a drape stiffness above 4.5.
8 . The mask of claim 2 wherein said second splash layer is comprised of an aperture film.
9 . A facemask for surgical use comprising a first spunbond splash layer on a side away from a wearer's face, a second splash layer made from a spunbond fabric or apertured film, a meltblown filtration layer and an inner layer suitable for contact with the wearer's face and wherein said facemask passes an ASTM F-1862-05 level 3 test.
10 . The facemask of claim 9 wherein said second layer has a basis weight of at least 0.8 osy and the first and second layers have a combined basis weight of at least 1.4 osy.
11 . The facemask of claim 9 wherein the filter layer has an air permeability value greater than 40 CFM/Ft 2 .
12 . The facemask of claim 9 having an air permeability of at least 30 CFM/Ft 2 .
13 . The facemask of claim 9 wherein said outermost splash layer has a drape stiffness above 3.5.
14 . The facemask of claim 9 wherein said outermost splash layer has a drape stiffness above 4.0.
15 . The facemask of claim 9 wherein said outermost splash layer has a drape stiffness above 4.5.
