Abstract
A textile fabric has at least one raised surface incorporating multicomponent fibers formed of at least a first polymer and a second polymer disposed in side-by-side relationship. The first polymer and the second polymer 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.
