Abstract:
1. Textile fabric comprising: at least one raised surface upon a base, the 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 exhibiting differential thermal elongation to cause the multicomponent fibers to bend and/or curl, the multicomponent fibers being configured to bend and/or curl relative to the base, toward a relatively reduced loft of the raised surface, in response to increasing ambient temperature, and unbend and/or uncurl relative to the base, toward a relatively increased loft of the raised surface, in response to decreasing ambient temperature, thereby reversibly adjusting insulation performance of the textile fabric in response to ambient temperature conditions.
