  We investigate actuation of woven fabrics including active Janus fibres with
an imposed twist, which bend in variable directions upon phase transition
between isotropic and nematic state. The essential feature of textiles
incorporating a pair of Janus fibres with a mismatched pitch or handedness of
coiling is the existence of multiple stable shapes with different energies
within a certain range of the extension coefficient. If the active fibres are
closed into a ring, torsion develops to accommodate adjustment of the direction
of bending. The structure is generally stabilised by adding more passive
filaments, and multistability is observed also in this case.
