Abstract
An enhanced filtration multilayer laminated fabric includes an air permeable, moisture-vapor-transmissive central layer such as polytetra-fluoroethylene (ePTFE) sandwiched between a first pair of nonwoven textile layers and a second pair of woven textile layers. The laminated fabric may also feature a fire resistant application. The top textile layer may also include a permanent, highly breathable and highly durable electro-static discharge feature added to the inside of the layer by laying down a carbon based printed pattern on the inside of the layer. The filtration fabric may be utilized to manufacture a wearable garment that is aesthetically pleasing and comfortable to wear in all weather conditions and which effectively filters airborne particulates from entering a user's respiratory system by blocking particulates having a size of 0.3 microns and larger from inhaled air for a user's respiratory system with a particle blocking efficiency of at least 90%.
