Description
Technical field
The present invention relates to a kind of jute degumming method, particularly relate to the method that a kind of applying composite enzyme comes unstuck to jute.
Background technology
Because flax fibre has sucting wet air permeability, low static behaviour and good antibacterial characteristics preferably, crudefiber crop fabric clothing lining more and more is subjected to people's favor.The lining of existing crudefiber crop fabric clothing is meant that mainly flax, ramie raw materials or this type of raw material and other fiber carry out blending/interweave as cotton, wool, chemical fibre, silk etc. and make, but, make that the crudefiber crop textiles does not have to be more widely used because flax, ramie price are higher.And jute is the second-biggest-in-the-world cellulose fibre that is only second to cotton, and it is cheap, and compares with flax, ramie and to have better hygroscopicity and drapability, and antibacterial ability is only second to hemp, has huge using value and potentiality to be exploited.But because the content of lignin higher (can reach 10-13%) in the jute is higher several times than flax, uses common Degumming method and tossa is come unstuck, removes lignin be difficult to obtain desirable effect, this has restricted the application of jute aspect garment material greatly." Tianjin University of Technology's journal " August the 24th in 2005, the influence that cellulase, hemicellulase, lignoenzyme and pectin depolymerase are handled tossa studied in volume the 4th phase " enzyme is handled a tossa Effect on Performance " literary composition, what but this article was mainly studied is to utilize above-mentioned various enzyme separately tossa to be handled respectively, even wherein mentioning complex enzyme handles, also only be to utilize laccase and hemicellulase compound with cellulase respectively, facts have proved that this article disclosed method is unsatisfactory to the effect that tossa comes unstuck, removes lignin.Chinese patent literature CN1232691C discloses the method that a kind of applying composite enzyme comes unstuck to jute, this method with the complex enzyme of pectase and laccase to the tossa processing of coming unstuck, the tossa of gained through with other fiber as cotton, chemical fibre blending or interweave and can satisfy the requirement of garment material substantially.But above-mentioned patent documentation disclosed method is desirable not enough to the removal of lignin impurity in the tossa, clearance only is about 76%, the content of lignin is still higher in the tossa of gained, need with other fiber as cotton, chemical fibre blending or interweave, the quality of the garment material that makes is still waiting further raising.
Summary of the invention
For this reason, the method that provides a kind of applying composite enzyme that jute is come unstuck is provided technical problem to be solved by this invention, and this method can effectively be removed pectin and the lignin impurity in the tossa.
For solving the problems of the technologies described above, technical scheme of the present invention is: the method that a kind of applying composite enzyme comes unstuck to jute, and described complex enzyme comprises pectase and laccase, may further comprise the steps:
A. will jute be flooded by the complex enzyme aqueous solution that pectase and laccase are mixed with, the weight ratio of the described complex enzyme aqueous solution and jute is 15: 1, and the weight ratio of described complex enzyme and jute is greater than 2: 100 and smaller or equal to 5: 100;
B. adjusting described complex enzyme pH value of aqueous solution is 5.0-5.5, and is warming up to 55 ℃-60 ℃, keeps 25-50 minute;
C. the pH value of adjusting solution then is 7.5-8.0, keeps 25-50 minute under 60 ℃-70 ℃ temperature;
D. the jute after handling through described complex enzyme being carried out enzyme deactivation handles.
Said method also is included in described steps d and carries out the step that synergy is banked up and handled before.
Said method, described synergy time of handling of banking up is 6-24 hour.
Said method, the enzyme deactivation in the described steps d are treated to the high temperature washing or regulate the pH value and carry out enzyme deactivation processing, perhaps both combinations.
Said method, the weight ratio of pectase is 30-90% in the described complex enzyme.
Said method, the temperature of water is more than 75 ℃ when carrying out the washing of described high temperature; PH value when adjusting pH value is carried out the enzyme deactivation processing is more than 10.0 or less than 4.0.
Said method also is included in described step a and before jute is carried out pretreated step.
Said method, described preliminary treatment are one or more the combination in water-bath, acid bath or the hydrogen peroxide dipping.The temperature of described water-bath is 30 ℃ to 100 ℃; Use sulfuric acid or acetic acid during described acid bath.
Characteristics and content (other crudefiber crops such as relative flax, ramie at pectin in the jute and lignin self, content of lignin is higher), jute complex enzyme degumming method of the present invention, chosen the technological parameter that is complementary, especially increase the use amount of complex enzyme, the consumption of adjusting enzyme is greater than 2% of tossa weight, and other each parameter is adjusted in cooperation, make Degumming method of the present invention to remove lignin more effectively, obtain tossa with better spinnability than prior art.
Compared with prior art, technical scheme of the present invention has the following advantages: (1) method of the present invention adopts complex enzyme to the tossa processing of coming unstuck, the consumption of adjusting enzyme is greater than 2% of tossa weight, and other each parameter is adjusted in cooperation, and before carrying out the high temperature washing or regulate the processing of pH value inactivation, the jute after complex enzyme is handled carries out the synergy processing of banking up, can remove pectin and lignin in the tossa effectively, its pectin clearance is about 90%, reach as high as 96%, lignin removing rate reaches more than 79%, reach as high as 86%, the tossa after the coming unstuck of acquisition has higher spinnability.(2) method of the present invention had been carried out preliminary treatment before to the jute complex enzyme degumming, jute has been played expanded preferably effect, to weaken the associating power between filament, be more conducive to enzyme liquid and contact with the direct of flax fibre, can better remove pectin and lignin in the tossa.
