Wine lees fiber paper pulp and paper made thereof

Abstract

The invention relates to a lees fiber pulp and the method for producing paper with said pulp. Wherein, it uses the less generated by alcohol industry as raw material, via breaking, screening, braising, and washing, to produce the lees fiber pulp that containing the fibrin and hemicellulose; it can be mixed with the slurries made from wood, bamboo, straw, or recycled waste paper, into mixed pulp, to be fed to paper maker to produce paper; or it can only use the less as raw material to produce less fiber pulp, to be diluted and mixed with water to be fed to paper maker to produce paper. The invention enlarges the raw material resource of paper industry, reduce the producing cost of paper, and solve the problem of environment pollution.

Description

technical field

[0001] The invention relates to the production technology of pulping and papermaking, in particular, the invention relates to a distiller's grain fiber pulp and a method for making paper with the distiller's grain fiber pulp. Background technique

[0002] At present, China's papermaking technology is still at the middle and lower level in the world. The main reasons are: first, the high energy consumption. One ton of pulp only consumes 15 to 60 tons of water, while China needs 400 to 500 tons; second, the pollution is serious. After China took measures to ban logging to protect forests, the traditional paper industry mostly uses bamboo, rice straw, reeds and other materials. Plants are the main raw materials for papermaking, and its production scale is small. Compared with large-scale wood pulp production, its technical equipment is relatively backward. The discharge of wastewater from the papermaking industry in China is second only to the chemical industry,...
