| description | The invention belongs to the field of pulping and papermaking, and specifically relates to a preparation method of a natural-color bamboo fiber biochemical mechanical pulp. The method comprises the following steps: 1) preparing materials by a dry method; 2) sending bamboo chips obtained in the step 1) to a press for pressing; 3) mixing animal manure and the bamboo chips, and screened-out finely-divided debris such as bamboo sawdust, bamboo piths and knots according to a ratio, then performing aerobic fermentation composting, and adding efficient active biological complex bacteria while mixing;4) performing screening and dust removal treatment after fermentation is completed; 5) washing away surface substances of the bamboo chips after screening and dust removal, and removing excess water;6) performing pre-impregnation with a lye; 7) performing pulp grinding or pulp beating; and 8) performing papermaking. The method uses the combination of biological, chemical, and physical methods toproduce the natural-color |
