Abstract

The invention provides a myopia-preventing exercise book and a production process thereof, and relates to the technical field of papermaking. The myopia-preventing exercise book comprises myopia-preventing antibacterial paper which is bound into a book, the myopia-preventing antibacterial paper is composed of a middle layer, a light reflecting layer and a light absorbing layer, the light reflecting layer and the light absorbing layer are sprayed on the two sides of the middle layer respectively, and groove-shaped outer rings are arranged on the front face and the back face of the myopia-preventing antibacterial paper and located on a top spray head. The groove-shaped outer ring is gradually transited from creamy white to black from the binding side to the far side. The sweet leaves and the bagasse are used as papermaking raw materials, so that the utilization rate of resources is greatly improved, the bagasse is white, the use of a bleaching agent is reduced, the Chinese juniper is used as a raw material for resisting bacteria, pigment and a light absorption layer, the moss is used as a natural pigment, two printing and coating styles are matched to assist in regulating eye muscles, anti-myopia effect is far better than similar products in the market, and moreover, various raw materials are easy to obtain, the process is simple, and the overall cost is saved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an anti-myopia workbook and a production process thereof. Background technique [0002] At present, the anti-myopia effect on the market is mainly to use light yellow paper containing yellow dyes such as frozen yellow G and basic bright yellow O, so that the paper appears light yellow with a brightness of 51%-59%, and can reflect light with a wavelength of 500-550nm. Shade. Since the brightness of the paper and the chromaticity of the image printed on the paper form enough contrast to form the best visual environment, when using this exercise book for various studies and exercises, it can prevent myopia . However, the processing of these dyes has the problem of environmental pollution, and after being made into workbooks, although a comfortable visual environment can be provided for the user, the eye muscles of the user cannot be adjusted after long-term use, resulting in ...
