Abstract

The invention discloses a manufacturing method of crumpled colored paper for a paper scarf of dental department. The manufacturing method comprises the following steps: taking regenerated wood pulp long and short fibers as raw materials, beating and then mixing and pulping; adding a polyamine epichlorohydrin resin wet strength agent, a dry strength agent, a neutral dye and a color fixing agent before fibers subjected to pulp mixing are put on a net and molded; forming by adopting a wet-process paper machine and crumpling by a dry process; and after dyeing in the pulp, coiling and cutting to prepare finished-product paper. A production process is easy to control and the production cost is low; in a manufacturing process, any toxic and harmful substance is not added so that pollution to the environment is not caused; and after the product is abandoned, the product can be naturally degraded, so that low carbon and environment friendliness are realized; the paper for the paper scarf of the dental department, manufactured by the invention, has the characteristics of enough dry and wet strength, fine, smooth and soft paper sheets, no dust falling, good liquid absorption and liquid retention properties, no separation of pigments, biodegradation, environment friendliness and the like.

Description

technical field [0001] The invention relates to a kind of special paper and its manufacturing method, especially a kind of manufacturing method of crumpled colored dental paper scarf paper. Background technique [0002] Since China's reform and opening up, people's living standards have undergone earth-shaking changes, and people's consumption levels have also been greatly improved and improved. In particular, people's health, hygiene, and environmental awareness have undergone significant changes. Demand has also grown strongly. While paying attention to the material level, people's attention to oral health care is also gradually increasing. Dental health care, prevention and aesthetics are getting more and more attention. It can be said that the level of oral medical services is one of the criteria to measure the civilization and wealth of a society. China's oral medical industry is a good industry with rapid development and huge market potential. [0003] In the 1990s...
