摘要： A multi-layered face mask (100) coated with discontinuous patterns of phase change material (300) are incorporated into the face mask (100) construction to provide for cooling of the microclimate in the dead space of the face mask (100). Optimized cooling is achieved by strategic placement of layers coated with a phase change material (300) within the mask (100) construction and the amount and density of the phase change material (300) in contact with the temperature sensitive areas of the face, as well as areas experiencing the maximum amount of flux from exhaled breath. The shape of the mask (100) can also be adjusted to increase skin contact with the phase change material (300) and decrease dead space volume, which reduces the volume of warm exhaled air and can provide sufficient cooling with less phase change material (300). The discontinuous patterns of phase change material (300) also provide inter-layer spacing between the layers of the mask (100), which can improve splash resistance.

摘要： A splash resistant multi-layered structure is provided. The structure includes a specific arrangement of layers of material and a plurality of three-dimensional spacers (302) that helps prevent penetration through the structure by a fluid that contacts an outer surface of the structure due to a state of forced separation that exists between two adjacent layers (300, 400, 802, 804, 806, 808) of the structure due to the presence of the plurality of three-dimensional spacers positioned between the layers. The plurality of three-dimensional spacers can be positioned on one of the adjacent layers (300, 802, 804, 806, 808) of the structure such that a distance (D) at least as large as the maximum height (S) of the plurality of three-dimensional spacers separates the two layers from each other and can be present on a layer of material in a continuous or discontinuous pattern or can be present on a layer of material in a random fashion. The presence of the three-dimensional spacers can reduce the basis weight or eliminate one or more layers of the structure, which, in turn, can reduce thermal resistance, lower the pressure drop across the layers of the structure, and reduce the overall weight of the structure to enhance breathability and comfort.
