To provide a standard textile fabric which is quite effective, especially when layered with other textile fabrics for synergistic effect and enhancement of comfort, i.e. the textile fabric responsive to the change of ambient temperature by solving the problems wherein the standard textile fabric has properties set during fabric construction that are maintained despite changes in ambient conditions and physical activity.

The 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 specific thermal elongations, which cause 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.
