WIPO Patent Application WO/2017/030280

A1

The present invention relates to a warping device using a retroreflective yarn and a method for weaving a raw fabric using the same and, more particularly, to a warping device using a retroreflective yarn and a method for weaving a raw fabric using the same, wherein a retroreflective yarn is applied as a warp such that a twisting phenomenon is prevented during weaving, thereby making it possible to acquire a raw fabric with excellent quality. The present invention, described above, provides, as the technical gist, a warping device using a retroreflective yarn and a method for weaving a raw fabric using the same, the warping device comprising: a creel unit having multiple bobbins, around which a yarn is wound, cradled thereon such that the yarn is unwound; an aligning unit for aligning the yarn, which has been unwound from the creel unit, at a predetermined interval; and a winding unit for winding the yarn, which has been aligned by the aligning unit, around a beam, wherein the creel unit comprises a main frame comprising horizontal bars, which are installed vertically at a predetermined interval, and vertical bars, which are installed between the horizontal bars at a predetermined interval, and a cradling frame comprising first cradling bars, which are formed to protrude from the inner side of respective vertical bars, and second cradling bars, which are formed to protrude from the outer side of respective vertical bars; first bobbins, around which a synthetic fiber yarn is wound, are cradled on respective first cradling bars; and second bobbins, around which a retroreflective yarn is wound, are cradled on respective second cradling bars to be perpendicular to the first bobbins.
