Tape for Printed Label Production and Process for Producing Tape

Abstract

There are utilized at least two kinds of ultraviolet-fluorescent yarns with different chromophore, which is spun out of dope kneaded with a fluorescent material. When ultraviolet-fluorescent yarns and colorless yarns are wound around a beam or drum with or without infrared-fluorescent yarns, ultraviolet-fluorescent yarns are arranged repeatedly in specific color order in the traverse direction during the warping operation. These yarns as the warp are woven into a wide textile with a wide loom. In this weaving, ultraviolet- and infrared-yarns are interwoven in specific color order in parallel with each other over the entire width of the wide textile, which is cut into tapes with heating in the broader width than a space where the color order may be identified.

1 . A tape of obtaining printed label used as informative security label, the tape being cut into labels after designs and/or characters were printed on the surface thereof, comprising:
 a tape body that is colorless when irradiating it with a visible light; and   at least two kinds of ultraviolet-fluorescent yarns with different chromophore, the yarns being interwoven into the tape body in parallel with other yarns;   the ultraviolet-fluorescent yarns being arranged in specific color order in the traverse direction, the color order being repeated every rows selected from the group consisting of every at least four rows by means of two kinds of the yarns, every at least three rows by means of three kinds of the yarns and every at least to rows by means of at least four kinds of the yarns over the entire width of the tape, whereby the specific repetitive pattern on the label is identified by irradiation of ultraviolet rays.   
     
     
         2 . The tape according to  claim 1 , wherein a prescribed width of the first and end rows of ultraviolet-fluorescent yarns are defined while arranging them in specific color order, the color order being repeated every at least three rows by means of two kinds of yarns in the traverse direction, whereby the specific repetitive pattern on the label is identified by irradiation of ultraviolet rays. 
     
     
         3 . The tape according to  claim 1 , wherein, infrared-fluorescent yarns instead of one kind of ultraviolet-fluorescent yarns are interwoven into the tape in parallel with other yarns, whereby the specific repetitive pattern on the label may be identified by irradiation of both ultraviolet and infrared rays. 
     
     
         4 . The tape according to  claim 1 , wherein infrared-fluorescent yarns are interwoven into the tape in parallel with other yarns in addition to plural rows of ultraviolet-fluorescent yarns, whereby the specific repetitive pattern on the label is identified by irradiation of both ultraviolet and infrared rays. 
     
     
         5 . The tape according to  claim 1 , wherein textile design thereof is a satin weave on which a lot of the warp come to the surface, whereby chromophore of ultraviolet-fluorescent yarns or existence of infrared-fluorescent yarns is identified by irradiation of both ultraviolet and infrared rays on the surface of the label. 
     
     
         6 . A process for manufacturing a tape of obtaining printed label by means of at least two kinds of ultraviolet-fluorescent yarns different from each other in chromophore, the yarns being spun out of dope kneaded with a fluorescent material, which comprises:
 arranging ultraviolet-fluorescent yarns repeatedly in specific color order in the traverse direction when winding them together with normal colorless yarns around a warp beam by beam warping;   weaving ultraviolet-fluorescent yarns and colorless yarns as the warp with a wide loom while the ultraviolet-fluorescent yarns are interwoven in specific color order over the entire wide of a textile; and   cutting the wide textile into tapes with heating in the broader width than a space where the color order is identified.   
     
     
         7 . The process according to  claim 6 , wherein a prescribed wide of the first row and the end row of ultraviolet-fluorescent yarns are defined while arranging them repeatedly in specific color order in the traverse direction, after woven, the wide textile is cut into tapes with heating in the broader width than a space where the first row and the end row exist in the tape. 
     
     
         8 . The process according to  claim 6 , wherein infrared-fluorescent yarns are wound together with ultraviolet-fluorescent yarns and normal colorless yarns around a warp beam by beam warping, and they are woven as the warp with a wide loom. 
     
     
         9 . The process according to  claim 6 , wherein a wide satin textile on which a lot of the warp come to the surface is woven while rows of the warp are opened with a dobby or a tappet machine and colorless yarns of synthetic fiber are inserted as the woof into a shuttle path caused by this opening movement within a wide loom 
     
     
         10 . The process according to  claim 6 , wherein the warp and the woof composed of colorless yarns is made of a non-bleached polyester fiber.
