A filter includes a pleated filter element having a fibrous support layer and a filtration layer bonded to the fibrous support layer. The fibrous support layer and the filtration layer are both in pleated form to provide a plurality of pleats. A cured stiffening agent is applied to the fibrous support layer, and the pleated form is maintained. The fibrous support layer is bonded to the filtration layer by other than the cured stiffening agent.

Pleated filter designs and components therefor for elevated temperature application

An improved stretchable filtration fabric laminate is provided. The laminate includes a first fabric layer and a nanofiber layer. The laminate may be stretched without damaging the laminate. The laminate is thus suitable for incorporation into wearable protective garments, such as protective hoods, balaclavas, scarves, etc. that provide both protection and air filtration to the wearer.

Stretchable laminated filter material and protective article

A waterproof, vapor-permeable and air-permeable sheet material. The sheet material includes a waterproof microporous polymer substrate and a microporous thermoplastic coating layer attached to the polymer substrate. The thermoplastic coating layer is vapor-permeable and air-permeable. The thermoplastic coating layer is at least partially interpenetrated into pores of the polymer substrate forming an interface that prevents passage of water droplets, while permitting passage of water vapor and air, when a chemical is present on the sheet material that would otherwise cause the polymer substrate to permit passage of water droplets. The interface is resistant to chemical interference with at least the waterproof property of the sheet material.

Breathable, chemical resistant, durable, and waterproof coated porous membrane

A system, in certain embodiments, includes a protective membrane having first and second layers. The first layer is air permeable, vapor breathable, and liquid repellant. The second layer is vapor breathable, liquid repellant, and adsorptive of chemical and/or biological agents.

Composite membrane for chemical and biological protection

A waterproof, vapor-permeable and gas-permeable sheet material and a method of making are provided. The sheet material includes a waterproof microporous layer and a thermoplastic layer attached to the microporous layer. The thermoplastic layer is vapor-permeable and air-permeable. The microporous layer is at least partially integrated with the thermoplastic layer to form a zone that prevents passage of water droplets, while permitting passage of water vapor and air, when a chemical is present on the sheet material that would otherwise cause the microporous layer to permit passage of water droplets. The Zone can be considered to be resistant to chemical interference with at least the waterproof property of the microporous layer and inhibits detachment of the layers.
