Additive for preparation of cellulose and preparation method of cellulose

Abstract

The invention relates to an additive for preparation of cellulose and a preparation method of the cellulose. The additive is prepared from raw materials in parts by weight as follows: 10-15 parts of saccharomycetes, 10-18 parts of urea, 12-18 parts of fatty alcohol-polyoxyethylene ether, 8-12 parts of alkylphenol ethoxylates, 12-18 parts of lipase, 3-8 parts of cellolase, 3-8 parts of aspergillus niger and 3-8 parts of a hydrolytic enzyme. The additive prepared from the combined raw materials and added to fibrous raw materials for preparation of cellulose has stable performance and can shorten the fiber preparation process, prepared fibers have a uniform length, the beating degree (degree sR), the quantitation (g / m<2>), the tightness (g / cm<3>), the whiteness (%ISO), the opaqueness (%), the fracture length (km), the tearing index (mN*m<2> / g), the bursting strength index (KPa*m<2> / g), the folding strength (times by 180 degrees), the average length (mm) of fibers and the average width of the fibers (mu m) all reach the standards, and the cellulose has higher performance.

Description

technical field [0001] The invention relates to an additive for preparing cellulose and a method for preparing cellulose, belonging to the field of preparing cellulose from bamboo and wood. Background technique [0002] Among the existing published documents, such as US Patent No. US2179181 in 1938, it is specifically disclosed that cellulose can be dissolved without chemical transformation with the help of tertiary amine oxides. It is also stated in the cited patent document that by precipitating this cellulose solution, a cellulose molded body can be produced, but the production process is complicated, and the degree of polymerization of the produced fiber is low. [0003] A large amount of additives are used in the existing bamboo and wood fiber preparation process, but their components are complex and extremely unstable when added to the system, resulting in large differences in fiber length. Contents of the invention [0004] The technical problem to be solved by the...
