    • An object of the present invention is to provide an elastic woven fabric which has not only excellent elongation properties and elongation recovery properties but also a low washing shrinkage rate, and its producing method and producing apparatus.
      An elastic woven fabric comprises weft and warp yarns, the weft yarns including a plurality of elastic composite yarns 1 each of which comprises an elastic core yarn 10 and a sheath yarn 11 covering the elastic core yarn 10, and the warp yarns including a plurality of chemical fiber yarns and/or a plurality of natural fiber yarns,
      wherein each of the elastic composite yarns 1 is in a form of a singly-covered yarn, a number of turns of the sheath yarn 11 per 1 meter of the core yarn 10 being in a range of 1,000 to 2,500 T/m,
      and wherein a stretching magnification ratio of each of the composite yarns 1 in a weaving process is retained equal to or less than 1.30 folds based on the composite yarn 1 before weaving.
      By blowing a compressed air flow in a direction substantially opposite to a feed direction of the composite yarn 1 when weaving, it is possible to reduce a tensile force applied to the composite yarn 1 to decrease stretching of the composite yarn 1 in a weaving process, and therefore the stretching of the composite yarns 1 constituting the weft yarns of the elastic woven fabric can be kept low.

    • The screening arrangement (100) provides for adjustment of the light intake of a window, by providing an extensible screen (6) with variable permeability such that when traction is applied, the permeability of the material is increased. A roller shaft (1) is connected to drive means and traction means are provided to apply a traction force on the extensible screen (6) to bring the extensible screen (6) to a first stretched state in which the permeability of the material is increased, corresponding to a first screening position. From the first screening position, the extensible screen (6) is brought to a second screening position in which the extensible screen (6) is in a second stretched state by continued rotation of the roller shaft (1) in the unwinding direction. The permeability of the extensible screen (6) is decreased in the second stretched state relative to the first stretched state. According to the invention, the traction means comprises a cord system including at least one traction cord (3) in connection with the roller shaft (1) and the extensible screen (6). A spring device (5) provides pretensioning of the traction cord (3), the cord system being configured to apply a traction force on the extensible screen (6) such that the tension exerted by the cord system on the extensible screen (6) provides said first stretched state during unwinding of the extensible screen (6).
