Body Cooling Garment

The US Army NSRDEC seeks to commercialize through patent licensing a body cooling garment which utilizes fluid-carrying tubes and provides both air and vapor permeability to make a flexible, comfortable garment. This garment is breathable and launderable, and will maintain comfortable core body temperature in hot conditions, whether indoors or outside. The vest can be connected to a faucet or cooling unit and unhooked briefly for mobility, or be more permanently tethered.

Patent Abstract: 

The technology comprises both the cooling garments and the method for adhering tubing to the fabric substrate. The preferred method employs adhesive dots to fasten the tubing to the fabric, forming a single component. This component is fused to a second layer of fabric, creating a tricomponent construction, with the tubing "sandwiched" in the center of two breathable layers. This method eliminates the need for stitching to hold the tubing in place. Sewn tubing has the problem of potential pinhole puncturing of the tubing, skin irritation from the threads themselves, lengthy manufacturing time, and needleholes that allow unwanted chemicals to penetrate the fabric. This technology is also superior to brushed or rolled on adhesives which destroys porosity. Variations can be made for a chemical suit. Foot cooling is covered in a patent application. Five US patents have issued and a sixth patent application has been filed. US patent numbers are: 6,901,608, 6,813,783, 6,565,699, 5,538,583, and 5,320,164. The benefits of this product are: - A breathable, flexible, comfortable cooling garment - Lower manufacturing costs — eliminates stitching - Low pressure drop and up to 180 Watts of cooling power
