We investigate actuation of woven fabrics including active Janus fibres withan imposed twist, which bend in variable directions upon phase transitionbetween isotropic and nematic state. The essential feature of textilesincorporating a pair of Janus fibres with a mismatched pitch or handedness ofcoiling is the existence of multiple stable shapes with different energieswithin a certain range of the extension coefficient. If the active fibres areclosed into a ring, torsion develops to accommodate adjustment of the directionof bending. The structure is generally stabilised by adding more passivefilaments, and multistability is observed also in this case.
