The main production processes are: foam material, cooking materials, cleaning materials, drying white, playing materials, fishing paper, squeezed dry, baking paper.
Foam material, also known as dip expected, is to separate the different materials by rating, tied into small bundles, soak in the pond. Incubation time varies with the variety of raw materials, cut bamboo soaked in water after about half a month, tied bundles of straw soaked in the river generally 7 to 10 days, branches, hemp stalk of time soaking in 10 days . The purpose of soaking is to dissolve soluble contaminants in raw materials (except) to, for the manufacture of pulp and lay a good foundation.
Cooking material is an aqueous solution of alkali or lime treatment of raw materials at high temperatures, the adhesion between the fiber pectin, lignin, etc. to get rid of, so that the fibers spread out to become pulp. Cook raw material process is different with very different: boiled mulberry blisters the first 10 minutes with lime, then baked in the pan with the lime-huang for 5 days, even after removing piling fermentation. Just a little bit of lime straw cooking or pile fermentation, become pulp.
Material is to wash the slurry into the bag after cooking, after a water rinse and back and forth, the pulp mixed with ash and boiling stone and other materials washed solutes.

Drain is to wet sheet squeeze out excess water within, so that the wet paper with a certain intensity, in order to facilitate drying brush on paper. When the wet papermaking accumulated thousands of pages of paper, the use of press facilities, impose the appropriate pressure on the paper slowly out of the water. Must not press too much pressure, otherwise it will affect the quality of the wet sheet; press after the wet paper contains too much water and it is not, after too little to prevent the sub-paper or baking paper when exposed the loss occurred.
Also known as baking paper baking paper or drying of paper, is to use wet sheet into a dry product. Baking paper is to drain through a wet piece of paper to separate, and then drying the brush attached to the outside wall, using wall fires, heat, transfer to paper the wall of water evaporation, the dry sheet .
