  • the cloth that was produced by weaving the 100% polyester filament yarns having an average fineness of 120 to 180 deniers, weaving the 100% polyester DTY yarns having an average fineness of 150 to 300 deniers, or knitting (circular knitting) polyester having an average fineness of 30 to 50 deniers was refined, washed using water, and bleached.
  • the bleached cloth was dyed by means of a high temperature and pressure liquid dyeing machine (13O 0 C, 3 D/D, and 40 min) using a fluorescent yellow dye (trade name: LUMINOUS YELLOW) and then dried.
  • the dried cloth was treated by using the fluorine-containing water repellent (trade name: AG-713) and fixed in the forced convection oven at 16O 0 C by heating to produce a cloth having high visibility.
  • the cloth having high visibility and the backing cloth for lamination were laminated along with the fluorescent/luminescent film having high visibility to produce a cloth having high visibility for lamination.
  • a moisture-curable polyurethane hot melt adhesive resin having an NCO group at a terminal thereof was uniformly applied between the cloth having high visibility and the fluorescent/luminescent polyurethane film having improved visibility, luminance and strength in a dot or mesh form to perform lamination of the fluorescent/luminescent polyurethane film having high visibility. Subsequently, the fluorescent/luminescent polyurethane film having high visibility was exposed to the saturated vapor at 3O 0 C to perform aging so that the residual NCO group was hardened.
  • the film where the fluorescent/luminescent polyurethane coating solution composition having high visibility of Experimental example 17 and the compositions for the luminance and strength improving layer of Experimental examples A or B are sequentially applied have high water resistance, light resistance, and wear resistance but relatively low vapor permeability.
  • the film is capable of being laminated with the cloth as an outer shell.
  • the film where the fluorescent/luminescent polyurethane coating solution composition having high visibility of Experimental example 18 and the composition for the luminance and strength improving layer of Experimental example A are sequentially applied have high water resistance and vapor permeability, the film is capable of being laminated with the cloth as an inner shell.
  • a cloth having high visibility, a backing cloth for lamination having high visibility, and a fluorescent/luminescent cloth having high visibility that is laminated with a fluorescent/luminescent polyurethane film having improved visibility, luminance and strength according to the present invention may be applied to industrial goods that require high visibility such as clothes including safety clothes, mountain-climbing clothes, and fire fighting clothes, and display means including emergency exit displays and advertisement structures.
