Abstract
A textile fabric has at least one raised surface incorporating multicomponent fibers formed of at least a first material and a second material disposed in side-by-side relationship. The first material and the second material exhibit differential thermal elongation, which causes the multicomponent fibers to bend or curl and reversibly recover in response to changes in temperature, thereby adjusting insulation performance of the textile fabric in response to ambient conditions.
