Warping device using retroreflective yarn and method for weaving raw fabric using same

Abstract

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.

1 . A warping device using a retroreflective yarn, comprising: a creel unit having multiple bobbins, around which a yarn is wound, cradled thereon such that the yarn is unwound; an aligning unit to align the yarn, which was unwound from the creel unit, at a predetermined interval; and a winding unit to wind the yarn, which was aligned by the aligning unit, around a beam,
 wherein the creel unit consists of a main frame consisting of horizontal bars installed vertically at a predetermined interval and vertical bars installed between the horizontal bars at a predetermined interval, and a cradle frame consisting of first cradle bars formed to protrude from inner sides of the vertical bars and second cradle bars formed to protrude from outer sides of the vertical bars, so that first bobbins having a synthetic fiber yarn wound thereon are cradled on the first cradle bars while second bobbins having the retroreflective yarn wound thereon are cradled to be perpendicular to the first bobbins.   
     
     
         2 . The warping device according to  claim 1 ,
 wherein the second bobbin comprises:   a cylindrical body which has the retroreflective yarn wound around an outer circumference of the body;   a support plate formed to protrude from both ends of the body, in order to support and prevent the retroreflective yarn from leaving the body;   a tubular connector installed to pass through the inside of the body in a length direction; and   a hook-coupling pin which is installed to pass through the inside of the tubular connector and includes circular rings at both ends thereof to be hook-coupled to the second cradle bars.   
     
     
         3 . The warping device according to  claim 1 ,
 wherein the second cradle bars are installed at an angle ranging from 60 to 120° to the vertical length direction of the vertical bar.   
     
     
         4 . A method for weaving a raw fabric by means of a warping device using a retroreflective yarn, comprising:
 slitting a retroreflective film to form a retroreflective yarn;   a warping process that includes aligning first yarns including the retroreflective yarn then winding the same around a beam; and   a weaving process that includes using the first yarns wound on the beam as a warp thread and leading second yarns between the first yarns to be perpendicular to the same, so as to weave a raw fabric,   wherein the warping process is carried out by means of a warping device that includes a creel unit to unwind the first yarns,an aligning unit to align the first yarns unwound from the creel unit at a predetermined interval,and a winding unit to wind the yarns aligned by the aligning unit around the beam, and   wherein the first yarns unwound from the creel unit include a synthetic yarn unwound from a first bobbin cradled on the creel unit, as well as the retroreflective yarn unwound from a second bobbin which is cradled on the creel unit to be perpendicular to the first bobbin.   
     
     
         5 . The weaving method according to  claim 4 ,
 wherein the creel unit comprises a main frame consisting of horizontal bars installed vertically at a predetermined interval and vertical bars installed between the horizontal bars at a predetermined interval,and a cradle frame consisting of first cradle bars installed to protrude from inner sides of the vertical bars and second cradle bars installed to protrude from outer sides of the vertical bars,   wherein the first bobbin is cradled on the first cradle bar while the second bobbin is cradled on the second cradle bar.   
     
     
         6 . The weaving method according to  claim 4 ,
 wherein the weaving process includes a finishing process of feeding typical fiber yarns from both sides of a weaving device, in order to form a finished part at both ends of the raw fabric.
