Patent abstract

A smart (intelligent) textile that can control its porosity, shape, texture, loft, stiffness, or color by temperature change or moisture absorption by using polymer fiber torsional and tensile actuators. This temperature change can be due to a change in ambient temperature or by an external stimulus, such as electrothermal heating. Mechanisms to accomplish this include (a) direct actuation (contraction or expansion) of polymer fiber actuators in a textile structure (b) rotation of polymer fiber actuators helically wrapped around warp and/or weft yarns in a textile structure; (c) rotation of chenille type or ribbon-like warp (or weft) ends by polymer fiber torsional actuators; (d) contraction or expansion of piles or loops in a chenille type fancy yarn produced by using mandrel actuators as pile or loop part of the yarn; (e) buckling of warp (or weft) yarns by contraction of tensile polymer fiber actuators; (f) decrease in yarn diameter by a twisting effect of polymer fiber actuators; (g) contraction or expansion of segmented mandrel actuators with core filament, wire or yarns; or (h) rotation of differentially dyed polymer fiber actuators for color changing textiles.
