Summary: | PURPOSE: Security paper with a drug discoloration function and a manufacturing method thereof are provided to include a color fiber which expresses a discoloration function by reacting to solvent, acid, alkali and bleaching agents as a security component. CONSTITUTION: A manufacturing method for security paper with a drug discoloration function comprises following steps. A fiber or a fiber of a film type is manufactured in order to include solvent discoloration dyes or pigment or fluorescent dyes by radiating them (S10). Paper is manufactured by cutting the manufactured fiber into a regular length and adding the cut fiber in a cotton fiber (S30). When the cut fiber is added in the cotton fiber, 0.001-0.5 weight% of the fiber about the cotton fiber is added. In the step of manufacturing paper, the manufactured fiber is cut into a regular length of 3-5 mm and added in the cotton fiber when the manufactured fiber is smaller than 70 denier or the manufactured fiber is cut into a plate form or a single fiber form of less than 2 mm in a right angle direction and added in the cotton fiber when the manufactured fiber is more than 70 denier (S20,S40). [Reference numerals] (AA) Start; (BB) No; (CC) Yes; (DD) End; (S10) Manufacture security fiber by mixing dyes/pigment for discoloring solvent fluorescent dyes/pigment while process of radiating and producing fiber; (S20) Diameter< 70 denier?; (S30) Produce paper by cutting into the length of 3-5mm and adding to cotton fiber; (S40) Produce paper by cutting into the fiber length of 2mm or plate shape and adding to cotton fiber |
