brrr°’s Apurba Banerjee Speaks at SYFA Conference About Advances in Cooling Fabric

cooling fabricbrrr° Chief Scientist Apurba Banerjee, PhD, is delivering a compelling presentation today about how synthetic fibers are revolutionizing cooling fabric.

Banerjee is featured as the second speaker at the fall conference in Charlotte, North Carolina. hosted by the Synthetic Yarn and Fabric Association (SYFA), a non-profit trade group that represents suppliers and manufacturers in the synthetic fiber industry.

In her talk titled “Chill Out,” Banerjee explores advances in synthetic fibers such as thermal regulation through nano structures and recycled polyester.

Banerjee also discusses some misinformation in the marketplace, with some products being labeled as “cooling” when in reality they only wick away moisture.

“The term cooling should be reserved for fabrics that actually draw away heat,” Banerjee says.

brrr° uses natural cooling minerals embedded right in the yarn combined with active wicking and rapid drying to create a Triple Chill Effect that is instant and permanent.

brrr° Chosen to Present at Emory RAISE Forum Investor Conference

brrr° is excited to be selected as one of eight companies chosen to present at the Emory RAISE Forum conference today hosted by the Goizueta Business School at Emory University in Atlanta.

brrrº Cooling Fabrics include Cooling Minerals, Active Wicking, and Rapid Drying

The prestigious conference connects fast-growing startups that are already generating revenue with interested and active investors who are looking to place $1 million to $5 million in capital to close the gap in funding sources at higher levels.

Leaders of startups also receive consulting and mentoring from professors and other business leaders in the community.

“We look forward to sharing our business strategy with investors at the RAISE Forum as we prepare to raise $3 million to $5 million in equity funding,” said brrr° Founder and CEO Mary-Cathryn Kolb.

The RAISE Forum was created seven years ago by early stage investor Barry Etra to encourage collaboration across the entrepreneurial ecosystem in the Southeast, and is now a pillar of the Entrepreneurship program at Emory’s Goizueta Business School.

brrr°’s Banerjee Discusses Fashion and Function

For centuries, fashion was driven by beauty standards that seem downright barbaric today: tight corsets, heavy layers, and stiff structures that restricted movement.

Thankfully, today’s fashion is married with function and our clothing is more stretchy, breathable and comfortable to wear as we go about our daily lives at work and at play.

For a long time, Lycra and Spandex were considered cutting edge – clothes that included these ingredients fit better and had a perceived performance edge.

"Today’s fashion is married with function"

Now it’s time for our clothes to take another leap forward with smarter materials that can actually draw heat and moisture away from our bodies to keep us cooler, says brrr° Material Scientist Apurba Banerjee, Ph.D.

Yet cooling technology is shrouded in mystery.

Some companies claim that their clothes cool, but what they really mean is that they are good at wicking.

“We think it’s time for the textile industry to adopt a standard definition for ‘cooling’ and that should mean it has an innate cooling sensation that can be felt even when you’re not sweaty,” said Banerjee, who gave a well-attended presentation on the subject titled “Don’t Sweat It!” at the recent Functional Fabric Fair by Performance Days in New York City.

brrr° is a pioneer in cooling fabric, with patent-pending technology that achieves an instant and permanent cooling sensation by combining natural cooling minerals, active wicking, and rapid drying to create a “Triple Chill Effect™” that won’t ever fade or wash out.

Cooling technology is jumping beyond the athletic and fashion industries to also be used in denim, footwear, bedding, car seats, office chairs, baby blankets, uniforms, and medical applications.
