Method for preparing natural colored mechanical pulp by utilizing laccase to treat bagasse

摘要: The invention discloses a method for preparing natural colored mechanical pulp by utilizing laccase to treat bagasse. According the technical scheme, comprises steps that hot water pre-extraction is conducted on bagasse, and an interbody are adopted conduct first-stage biotreatment pre-extracted bagasse obtained after ground, then filtrate second-stage ground pulp. reaction conditions of moderate, unique product water, no chemical agent not used in whole technological process, environmental pollution problem solved, prepared coloredmechanical has good filtering performance, physical properties paper high.
