Title:
PRODUCTION METHOD FOR DEODORIZING PAPER
Document Type and Number:
WIPO Patent Application WO/2019/131083
Kind Code:
A1
Abstract:
Provided is a production method for deodorizing paper, in which particles having deodorant effects are contained, at a desired rate, into a thin paper sheet without a bias so that sufficient paper strength can be ensured, and stable quality can be maintained even when the paper sheet is formed into a roll-like product. The method comprises: a first process for dehydrating a band-like paper material placed on a screen net 16 of a wire part; a second process for transferring the dehydrated band-like paper material to a transfer means of a pressing part and further dehydrating the band-like paper material; and a third process for drying the dehydrated band-like paper material by means of a drying means of a drier part. Any one of the first process to third process includes a fourth process for ejecting, from ejection parts 17a-17e, a liquid that contains particles having deodorant effects. In the fourth process, the ejection parts 17a-17e have been arranged side by side in order to cause adhesion of the particle-containing liquid along the width direction of the band-like paper material, and the ejection parts 17a-17e sequentially eject the particle-containing liquid at a predetermined time interval so as to prevent occurrence of bias or damage in the fiber of the paper material.
