METHOD FOR WHITE LIGHT-EMITTING NON-WOVEN FABRIC WITH RGB COMPONENTAL FINE FIBER VIA MULTI-NOZZLE ELECTROSPINNING

摘要

PURPOSE: A manufacturing method of white luminescence nonwoven fabric is provided to produce white luminescence nonwoven fabric that may be used as a light emitting diode and that emits light of different colors by controlling an amount of dye. CONSTITUTION: A manufacturing method of white luminescence nonwoven fabric comprises the following steps. a) Each spray solution is prepared by dissolving each of red, green, and blue light-emitting dyes and a transparent resin in a solvent; and b) the spray solutions prepared in the step a) are electrospun on a collector from different nozzles, each respectively, through an electrospinning device when a voltage is applied thereto. A light-emitting wave range of the red light-emitting dye is from 580 nm to 650 nm, the green light-emitting dye is from 480 nm to 550 nm, and the blue light-emitting dye is from 390 nm to 450 nm. A weight ratio of the red light-emitting dye : the green light-emitting dye : the blue light-emitting dye is 0.07375 to 0.0765 : 0.041 to 0.04375 : 0.8825 to 0.88525.
