Abstract

A method for manufacturing tissue using recovered paper from corrugated fiberboard as raw material is provided. A method for manufacturing tissue using disclosed recovered paper from corrugated fiberboard as raw material comprises: (a) a step of inputting recovered paper from corrugated fiberboard into a pulper and dissociating fibers in weak alkali condition using sodium hydroxide, (b) a step of removing foreign materials of high concentration or large size in a cleaner or screen, (c) a step of removing foreign materials in a first double nip thickener through decompression dehydration, (d) a step of generating friction between fibers in a kneader, in which the foreign materials of high concentration or large size are removed, to disperse ink embedded in the fibers, (e) a step of removing ink particles in a flotator using air bubbles through flotation, (f) a step of removing low concentration or fine foreign materials in the cleaner or screen, (g) a step of removing fine foreign materials in a second double nip thickener through decompression dehydration, and (h) a step of inputting dye for dyeing to make the fiber a raw material of tissue level. The foreign materials are removed from primary white water using a first dissolved air flotation tank, which is dehydrated in step (C). The foreign materials are removed from secondary white water using a second dissolved air flotation tank, which is dehydrated in step (g). The white water through the first and second dissolved air flotation tanks can be recycled as dilution water. In addition, the present invention is able to produce an environmentally-friendly product since bleaching is not performed during the manufacturing process. Also, the present invention contributes to cost reduction by saving the bleaching agent and preventing loss of raw materials. Single fiberizing and fines content reduction not only enhance product strength, but foreign materials such as pitch, ash, ink, flake and waste synthetic resin are also removed through a serial screening process. Therefore, raw materials of tissue level minimizing problems during post-process can be made.
