14 Claims

1. A textile that is a woven structure, wherein the woven structure is comprising at least one twisted or coiled polymer fiber actuator that is operable to reversibly change either (1) the porosity of at least one single layer of the textile, (2) textile coloration, or (3) combinations thereof, in response to a change in temperature or moisture absorption, without substantially changing overall textile width and length, wherein the at least one twisted or coiled polymer fiber actuator comprises at least one twisted or coiled polymer fiber having a degree of twist in which the product of (a) the degree of twist per unit length multiplied by (b) average diameter of the at least one twisted or coiled polymer fiber is at least 50°.
