The ramie degumming method has sufficient deguming matched with the subsequent soda boil procedure so that three procedures, such as enzyme scouring, ramie retting and ramie washing, of the traditional biological dugumming are combined into one procedure and the time is shortened to half of original time, thereby enhancing the production efficiency.
Description
Technical field
The present invention relates to textile industry, promptly a kind of method of utilizing complex enzyme formulation to carry out China grass degumming.
Background technology
Ramie belongs to Urticaceae perennial root herbaceos perennial, its fiber content is more than 60%, its bast fiber is especially long and solid, it is a kind of important textile industry raw material, yet being attached with a large amount of colloids on the ramee, accounting for 25～30% of gross weight, mainly is pectin, hemicellulose and lignin etc., therefore to obtain industrial available fiber, the processing of must coming unstuck.Degumming method commonly used at present is chemical caustic soda high pressure kiering method, this method produces a large amount of acidic and alkaline waste waters, cause serious environmental to pollute, therefore have many enterprises carrying out the test of enzyme preparation China grass degumming, its technological process is: it is numb to prick handle → dress cage → enzyme white silk → retted fibre → wash fiber crops → soda boiling → copy fiber crops → rinsing → oil supply → de-oiled water → tremble fiber crops → baking.Above-mentioned technology is a kind of biological one chemical combined degumming tech, and wherein part technology is consistent with the method for traditional chemical Degumming, and institute's difference is, the sour preimpregnation of former usefulness is changed into enzyme white silk, retted fibre, washes the fiber crops sterilization, is illustrated one by one below.
Enzyme is practiced: will account for the complex enzyme formulation of ramie weight 1～3%, the textile auxiliary that accounts for ramie weight 0.2～0.5% adds degumming baths, the weight ratio of ramie and degumming baths is 1: 12～15, adjusting the degumming baths pH value is 8.5～9.5, adding the ramie immersion comes unstuck, temperature is controlled at 40～50 ℃, and usually time is 2～10 hours;
Retted fibre: after enzyme practice to finish, pull out and topped, under the temperature about 40 ℃, placed 12～24 hours with Polypropylence Sheet;
Wash fiber crops: the fiber crops that will finish the system of macerating of coming unstuck were sterilized 30 minutes with 90 ℃ hot-water soak;
Soda boiling: the coming unstuck fiber crops after will sterilizing add in the alkali lye, and the concentration of NaOH is 6～10g/L, and according to producing needs, add 0.2～0.5% auxiliary agent of ramie weight, boil under the normal pressure 2～4 hours;
Thereafter operation is undertaken by the traditional chemical degumming tech.
Though said method has reduced the generation and the cost of material of acidic and alkaline waste water, usually time is long, and efficient is low, and energy consumption is big, and it is little that production cost reduces amplitude, and while factory building, equipment increase more, invest bigger.
Summary of the invention
In order to shorten the time of China grass degumming, enhance productivity, reduce production costs, energy savings the present invention proposes a kind of method of utilizing the biology one chemical combined China grass degumming that complex enzyme formulation carries out.
This method of utilizing complex enzyme formulation to carry out China grass degumming, its step soak for pricking handle → dress cage → enzyme → and soda boiling → copy fiber crops → rinsing → oil supply → de-oiled water → tremble fiber crops → baking is numb, and it is characterized in that: the step that above-mentioned enzyme soaks is as follows:
Earlier the water of 13～15 times of ramie weight is heated to 56～60 ℃, water is transferred to the liquid complex enzymes that pH value 8～9 backs add ramie weight 2～4%, stir evenly with NaOH with steam, add ramie again, carry up and down 3～4 times, fiber crops are soaked evenly, 50～55 ℃ of static lower seal insulations, 3～5 hours;
The composition of above-mentioned liquid complex enzyme comprises: alkaline pectase, dextranase, neutral proteinase, zytase and mannase, and their vigor is respectively 300U/ml, 4000U/ml, 600U/ml, 500U/ml, 600U/ml;
The step of above-mentioned soda boiling is as follows: the ramie with processing 550Kg is an example, the water that in mixer, adds 13～15 times of ramie weight earlier, adding weight concentration again is 30% liquid NaOH160Kg, solid sodium phosphate trimer 5Kg, the liquid glass 22Kg of Baume degrees 36～38, heat water to 60～70 ℃ then, it is fully dissolved, make and boil material, simultaneously enzyme being soaked good ramie drains, drop in the autoclaving pot, boiling in the material suction saucepan of having prepared, build pot cover, open the vapour kiering, and guaranteed under operating pressure 0.22～0.25MPa kiering 1.5～2.5 hours;
Other operations are undertaken by the traditional chemical common process that comes unstuck.
The operative temperature of complex enzyme used in the present invention is 45～55 ℃, can not and be lower than 45 ℃ above 60 ℃, since better controlled of the present invention the operative temperature of complex enzyme, biological degumming is more abundant, cooperates follow-up soda boiling operation, make traditional biological degumming enzyme white silk, retted fibre, wash numb three process and be combined into one procedure, time foreshortens to original half, has improved production efficiency, has saved the energy, simultaneously can reduce number of devices such as soaking bucket, saucepan, reduce investment.
The specific embodiment
Below in conjunction with the specific embodiment, the present invention is described in detail as follows:
This method of utilizing complex enzyme formulation to carry out China grass degumming, step soak for pricking handle → dress cage → enzyme → and soda boiling → copy fiber crops → rinsing → oil supply → de-oiled water → tremble fiber crops → baking is numb.
Wherein the enzyme step of soaking is as follows: with steam the water of 14 times of ramie weight is heated to 58 ℃ earlier, after with NaOH water being transferred to pH value 8.5, the liquid complex enzyme that adds ramie weight 3%, stir evenly, add ramie again, upper and lower carrying 4 times, fiber crops are soaked evenly, at static lower seal, be incubated 53 ℃, 4 hours.
Consisting of of above-mentioned liquid complex enzyme: alkaline pectase, dextranase, neutral proteinase, zytase and mannase, their vigor is respectively 300U/ml, 4000U/ml, 600U/ml, 500U/ml, 600U/ml.
