Description
Technical field
The present invention relates to a kind of method of preparing bamboo primary fibre using composite biological enzyme, belong to the manufacturing technology field of weaving with native cellulose fibre.
Background technology
By literature search, at the developmental research initial stage of bamboo fibre, be to adopt chemistry (spinning) method to produce viscose glue (type) bamboo fibre basically, these technologies have been destroyed bamboo fiber bundle, easily make product lose ecological attribute, and the sewage after the chemical treatment is difficult to handle.Also be in laboratory stage, the industrialization production of being unrealized and utilize physical method to extract bamboo fiber.02133494.3,200310108826.1,200410046802.2,200410060809.x etc. existing bibliographical information related to the present invention mainly contains:, all be to adopt the single creature enzyme that bamboo is handled, but the cycle is longer, generally need 3～7 days, and equipment and process conditions are had relatively high expectations.
Summary of the invention
The object of the present invention is to provide a kind of technological design reasonable, can satisfy the method for the preparing bamboo primary fibre using composite biological enzyme that can spin requirement and ecological, environmental protective.
The present invention is the method for preparing bamboo primary fibre using composite biological enzyme, with the bamboo fiber crops is raw material, remove materials such as part lignin, hemicellulose, pectin through conventional pretreatment process, it is characterized in that pretreated bamboo fiber crops were handled in the compound bio enzyme aqueous solution 1～5 hour, in pectase solution, handled 1～5 hour again after conventional post processing makes bamboo fiber; Described compound bio enzyme aqueous solution is any of following single or mixture: laccase, zytase, the mixture of laccase and zytase, the mixture of laccase and cellulase, the mixture of zytase and cellulase, the mixture of laccase and zytase and cellulase; The concentration of described laccase, zytase is respectively 20～50g/L, and the concentration of cellulase is 2～6g/L; The concentration of pectase is 10～25g/L in the described pectase aqueous solution.
PH in the described compound bio enzyme aqueous solution can be 4～6.
PH in the described pectase aqueous solution can be 8～10.
The treatment temperature of described bamboo fiber crops in the compound bio enzyme aqueous solution can be 45～60 ℃, and the processing time is 1～4 hour.
The treatment temperature of described bamboo fiber crops in the pectase aqueous solution can be 45～60 ℃, and the processing time is 1～4 hour.
Described pretreatment process can comprise kiering, pickling, centrifugal dehydration, mechanical roll compacting, water flushing etc.
Described bamboo fiber crops can by after the felling of bright bamboo by hand or mechanical system block by ring, the green grass or young crops of bamboo is slightd or/and Huang is slightd torn the well-thought-out plan fiber crops again.
Described bright bamboo can be bright mao bamboon or bright cizu or cadmium yellow bamboo etc.
The cellulase that the present invention selects for use is an endo cellulase, because bamboo fiber is dense, cellulase is difficult for degraded cellulose molecule in the infiltrated fiber, and fibre strength can be not impaired, but can play certain " explosion " effect, other endonuclease capables are permeated better and act on bamboo fiber.The present invention is by analysis-by-synthesis and comparison to existing bamboo fiber preparation technology, through repetition test research and checking, select the compound bio enzyme aqueous solution and pectase aqueous solution synergy for use, and rationally determined the concentration of each biology enzyme, pH value in the solution, treatment temperature, process conditions such as processing time, both can be to the lignin in the bamboo fiber crops, hemicellulose, pectin etc. carry out further effectively handling, the natural attribute that has kept cellulosic active ingredient and bamboo product in the bamboo product again, make it pointed strong, vigor is big, bamboo fibre is injured advantages such as little, and employed biology enzyme is commercially available industrial goods, low price.The bamboo fiber fineness of producing, intensity, pliability etc. all satisfy can spin requirement, can be used for making nonwoven fabric and family to spin decorative product, has green, nice and cool, fast excellent properties such as do.
