Xuan paper manufacturing method

Abstract

The invention discloses a Xuan paper manufacturing method, which comprises the steps of pteroceltis tatarinowii peeling, pteroceltis tatarinowii bark bleaching, pteroceltis tatarinowii bark pulping, straw pretreatment, straw bleaching, straw pulping, pulp mixing, papermaking, draining, baking and inspection, cutting, and packaging, wherein pectinase is added in the pteroceltis tatarinowii bark bleaching process, and a layer of epoxy resin is brushed in the baking process. According to the method, the manufacturing period of Xuan paper can be greatly shortened; the epoxy resin is immersed into the Xuan paper in the baking process, so that the connection strength between fibers is enhanced, the internal gap distance of the Xuan paper is reduced, and the air permeability is good; pectinase is added in the pteroceltis tatarinowii bark soaking process, so that complete pteroceltis tatarinowii bark fibers can be extracted, and the alkali consumption is reduced; the Xuan paper manufactured by the method is pure white and fine in texture, clear in texture, good in ink wetting property, capable of effectively retaining pen ink, uniform in ink diffusion and free of sawtooth; and the manufactured Xuan paper is not easy to deform, good in stability and capable of being stored for a long time.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for making rice paper. Background technique [0002] Xuan paper has a long history of production and is a typical representative of traditional handmade paper. The selection of materials for Xuan paper is closely related to the geography of Jing County, the place of origin. Green sandalwood bark is one of the main local tree species, so green sandalwood bark has become the main raw material of rice paper. And because rice is grown locally, its rice has also become one of the raw materials. [0003] The production of rice paper can be roughly divided into 18 processes, and if subdivided, it can exceed Shangbaidao. The traditional method of cutting rice paper is to steam the branches of Qingtan tree first, then soak them, then peel them off, dry them in the sun, add lime and soda ash, and steam them again to remove impurities. After washing, tear them into thin stri...

AI Technical Summary

Problems solved by technology

[0004] The whole manufacturing process is relatively complicated and takes a long time. The raw materials can be exposed to the sun and rain for as long as one year, and the fibroblasts are often incompletely extracted during the processing of the green sandalwood bark.
