Even as snow continues to blanket much of the country, most of us are gearing up for summer and the hot temperatures to come. Last year was the hottest ever recorded in the US, with July 2012 the warmest month on record. With this continuing warming trend, many companies are looking to play in the ever growing cooling apparel market. CoolCore is the latest to throw their hat in the ring with a cooling technology that claims to lower the temperature of the fabric to 30% below your skin temperature for up to several hours.
Much like Columbia's Omni-Freeze ZERO, CoolCore cooling fabric technology uses the power of evaporation to cool your skin. The fabric captures moisture either from your sweat or added water and regulates the rate of evaporation in order to reduce the temperature of the fabric and therefore your skin.
The fabric derives its cooling function from its construction, which uses a number of different fibers that create a capillary system, wicking away moisture from your skin, circulating the moisture throughout the entire garment, and regulating the rate of evaporation before releasing the molecules into the atmosphere. The fibers closest to your skin wick away moisture (polyester), while the interior of the fabric uses fibers that retain or store liquid (hollow fiber) and the outside of the fabric is configured with fibers that regulate the rate of evaporation to be slower than the rate of absorption (nylon).
During the manufacturing process, the fabric is "peached" or brushed on both sides, effectively entangling all the fibers together to create the best cooling environment. CoolCore’s technology is free of chemicals, polymers, gels, crystals or phase changing materials. The fibers used to create the fabric are all biologically safe and hypo-allergenic, as well as anti-microbial and anti-bacterial.
The cooling fabric technology was invented and patented by Dennis Ackroyd (part of the original Polarfleece team at Malden Mills) and Joseph Turner, original owners of Cool Comfort Technologies in Windham, Maine. In 2011, the duo sold the intellectual property and other assets to CoolCore LLC of Portsmouth, NH, who is now looking to both license the fabric as well as release their own line of cooling apparel in Spring 2014, creating a multi-national brand in the process.
