Embodiment

[0034] A kind of preparation method of ramie paper, comprises the following steps:

[0035] (1) Material preparation: peel off the ramie bark from the hemp stem, remove the green bark, and expose to the sun and rain for 2 to 3 months in the open air; the ramie fiber containing water is strongly oxidized by ozone generated by ultraviolet rays in the sun, and the residual ramie in the ramie material The lignin is oxidized to make the pulp white. Since chlorine bleaching agent is not used and the reaction is carried out under mild reaction conditions, the cellulose will not be degraded, so the paper made is durable and does not pollute the environment. advantage;

[0036] (2) Soaking hemp: Take 200 kg of ramie skins and put them in the retting pool, soak for 8-10 days, add 2000g of alkalophilic bacillus preparation before soaking to make the ramie skins undergo microbial fermentation to achieve the purpose of degumming, in order to obtain clean ramie fibers , the water needs to...

Abstract

The invention discloses a manufacturing method of ramie paper. The method has the advantages that the ramie (bast) is used as the raw material, and the paper is manufactured by the traditional manual methods of ramie sun and rain bleaching, microorganism fermentation and degumming, processing of natural paper medicines, dying of plant pigments, and the like, so the damage to the plant fiber is avoided, the quality of paper products is furthest improved, and the wastes generated in the whole technological process can be completely degraded, thereby realizing the non-toxic, non-harmful and pollution-free effects and meeting the national environment-protection standards; the manufactured ramie paper has the characteristics of classic elegance, high flexibility, softness and attractive appearance, is suitable for the restoration of ancient rare books and the creation of calligraphy and drawing, and can reach the better effect of non-decay for thousands of years; the technical standard is normative, so the method is suitable for factory production, and the good economic benefits and social benefits are realized.

Description

technical field [0001] The invention relates to the technical field of traditional papermaking, in particular to a method for making ramie paper. Background technique [0002] my country has a long history of planting and using ramie. The "Book of Songs Wang Feng" compiled in the Spring and Autumn Period (770-476 BC) records: "There is hemp in the hill." "The Book of Songs Chen Feng" records: "The East Gate It can be used for retting.” According to historical materials and research by relevant experts, papermaking originated from the floating wadding produced by spinning and weaving, and is closely related to retting. According to the Southern Dynasty Fan Ye's "Book of the Later Han·Cai Lun Biography": "Since ancient times, the book deeds have been compiled with bamboo slips; those who use silk (fine silk) are called paper. It is expensive but simple and heavy, which is not convenient for people. Lun Nai created ideas, using tree skin, hemp heads, cloth, and fishing nets as ...
