Cellulose Fiber Blended Fabric

This fabric is designed to keep you comfortable and prevent a sticky or steamy feeling, even when you sweat. It achieves this by incorporating cellulose fibers that expand by at least 2% when they absorb water. The claims narrow this to fibers that specifically extend by 3% or more when wet, making up at least 10% of the fabric's weight.

Why it matters: Since 2007, significant advancements in cellulosic material science and smart textile technologies could enable more precise and cost-effective production of fibers with the claimed water-responsive dimensional changes. This might simplify manufacturing the specialized cellulose fibers required.
