Method for preparing bamboo primary fibre using composite biological enzyme

Abstract

A method for preparing a bamboo fiber by a compound bio-enzyme belongs to the technical field of manufacturing the natural cellulose fiber used for weaving. Bamboo linen is used as raw material; the bamboo linen normally processed is treated in the water liquid of the compound bio-enzyme for 1 to 5 hours, then is treated in a pectase liquid for 1 to 5 hours, then the bamboo fiber is obtained after normal processing; the water liquid of the compound bio-enzyme is any single or mixture of laccase, xylanase, the mixture of the laccase and the xylanase, the mixture of the laccase and cellulose, the mixture of the xylanase and the cellulose as well as the mixture of the laccase, the xylanase and the cellulose; the concentration of the laccase and the xylanase are respectively 20 to 50g / L; the concentration of the cellulose is 2 to 6g / L; the concentration of the pectase in the pectase liquid is 10 to 25g / L. The technique of the method is reasonably designed; the fineness, the intensity and the softness of the prepared bamboo fiber can all meet the weaving requirements.

Description

technical field [0001] The invention relates to a method for preparing bamboo raw fibers with compound biological enzymes, and belongs to the technical field of manufacturing natural cellulose fibers for textiles. Background technique [0002] According to literature search, in the early stage of bamboo fiber development and research, chemical (spinning) methods were basically used to produce viscose (type) bamboo fibers. sewage is difficult to treat. However, the extraction of raw bamboo fibers by physical methods is still in the laboratory stage, and industrial production has not been realized. The existing literature reports associated with the present invention mainly include: 02133494.3, 200310108826.1, 200410046802.2, 200410060809.x, etc., all of which use a single biological enzyme to treat bamboo, but the cycle is long, generally 3 to 7 days, and the equipment and higher process conditions. Contents of the invention [0003] The purpose of the present invention ...
