US Patent:

20130294002, Nov 7, 2013

Filed:

Dec 20, 2012

Appl. No.:

13/722010

Inventors:

Leon S. Moser - Raleigh NC, US
Katherine A. McNamara - West Newbury MA, US
Leo Crotty - North Hampton NH, US
Alan Smithies - Overland Park KS, US

International Classification:

H05F 3/00

US Classification:

361212

Abstract:

An enhanced protective cover includes a top and bottom textile layer and an air permeable, moisture-vapor-transmissive, expanded polytetrafluoroethylene membrane layer located between the two textile layers. The cover exhibits an MVTR rating of at least 4000 g/m/day. The protective cover also includes a top layer coating or fibre treatment of a nano-ceramic material designed to increase the durability of the cover and increase the resistance to abrasion and wear while also resisting environmental conditions including exposure to solar radiation, temperature and humidity. Alternatively, the upper layer of the protective cover may incorporate ceramic coated fibers or ceramic co-extruded fibers, or carbon nanotubes. The protective cover 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.

Abstract:

A multi-layer liner material for use as a thermal and acoustical insulator which is lightweight, breathable, hydrophobic, oleophobic and fire-resistant. A central insulation core layer is contacted on a first surface by a first highly breathable layer and on a second surface by a second highly breathable layer, such that these three layers are resistant to water or oil penetrating the insulation core layer causing the liner to gain weight. The first and second highly breathable layers are preferably made from inherently flame resistant fibers and treated with a fluorocarbon surface treatment for water repellency, UV resistance and mold/mildew resistance. The first highly breathable layer is adjacent a facing layer while the second highly breathable layer is adjacent a backing layer. At least one surface of one of the first or second highly breathable layers, or facing or backing layers may include a carbon printing pattern to provide ESD protection.

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%.

International Classification:

C23C 16/511
H05F 3/00

Abstract:

A multi-layer fabric used to fabricate a garment or a protective cover includes a top and bottom textile layer and an air permeable, moisture-vapor-transmissive, expanded polytetrafluoroethylene middle layer. The fabric exhibits an MVTR rating of at least 4000 g/m/day. The fabric may also include a top layer coating or fiber treatment of a nano-ceramic material designed to increase the durability of the garment/cover and increase the resistance to abrasion and wear while also resisting environmental conditions including exposure to solar radiation, temperature and humidity. Alternatively, the upper layer of the multi-layer fabric may incorporate ceramic coated fibers or ceramic co-extruded fibers, or carbon nanotubes while in another embodiment may also feature a fire resistant application as well as 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.
