Description

[Detailed Description of the Invention] When paper is made from bamboo pulp, if the thin film inside the bamboo material gets mixed in, the product value of the paper will be lost and it cannot be sold as a product. After that, the thin film has been peeled off) Throw away the boiling water, take out the boiling bamboo from the pot, expose it to water for about 1 hour, and continue boiling again to obtain material from which high-quality pulp can be extracted. After boiling for about 10 hours, and submerging in a wooden or plastic container in a chemical containing a fiber decomposer and bleach for about 3 to 4 hours, the bamboo material will turn milky white, so the bamboo material should be pulled out again. Transfer to another container, spray the bamboo material with water and expose it to water for about 1 hour at a pressure that will naturally separate the fibers. After confirming that the fibers have been separated, adjust the water pressure to a pressure similar to that of a babbling stream. Bamboo pulp can be produced after about 20 hours of continuous use.When the chemical mixture of fiber decomposition material and bleaching agent loses its effectiveness, the bamboo material added will not become milky white, so replace the chemical and use the method described above. Repeat the work process.

Claims (1)

[Claims] 1. All the processes necessary to produce chemical pulp from natural bamboo. In particular, the process of increasing the value of bamboo pulp by removing the inner membrane of the natural bamboo during the boiling process, and the beating process for fiber separation. A method of producing high-quality pulp by decomposing fibers using the water pressure of bleaching water without performing any other operations.
