<p>PURPOSE:To stably obtain the subject woven fabric having high quality by using a covering yarn containing an elastic core yarn and having a specific elongation as a weft and weaving by an air-jet loom to fly the weft with a main nozzle, etc., in a specific direction. CONSTITUTION:A covering yarn containing elastic yarn as a core yarn and having an elongation of >=50% is used as a weft. The weft is forced to fly through a yarn guide hole 2 of a modified reed 1 in opened warps 4 by the aid of air jet ejected from a main nozzle 5 and is successively delivered by air jet streams ejected into the yarn guide hole 2 from plural assistant nozzles 3 placed adjacent to the main nozzle 5. The weft is forced to fly in the direction of the width of fabric by this procedure. Finally, an end of the yarn is held with a stretch nozzle 6 to effect the weft-insertion and obtain the objective woven fabric. Preferably, the feeding tension of the weft is 0.04-0.2g/d and within the elastic limit of the wound fiber of the covering yarn and the holding force of the flying weft with the stretch nozzle is 0.1-0.7g/d based on the weft.</p> |
