Description
Technical field
The present invention relates to field of textiles, be specifically related to china grass degumming process and matching used activator and boiling-off additive.
Background technology
At present, China's China grass degumming technology has still been continued to use the chemical Degumming technology since the fifties basically, 7～8 hours normal pressure degumming boiling-off time, and pressurization degumming boiling-off 4～5 hours, the kiering time is long, energy consumption is high, degumming waste water is seriously polluted.The degumming technology of this backwardness has jeopardized the existence of China's ramie textile industry, to the stage that non-change.
Summary of the invention
The technical problem to be solved in the present invention is exactly the shortcoming that overcomes prior art, and the energy-saving environment-friendly type china grass degumming process that a kind of kiering time is short, the steam consumption is low, small investment, production cost reduce, end product quality improves is provided.
Energy-saving environment-friendly type china grass degumming process of the present invention comprises dress cage, pickling, washing, kiering, washing, pickling, oils, dries, and increases the twice preliminary treatment before kiering: promptly spent lye is washed fiber crops and concentrated base soaks fiber crops, banks up, and specifically technological parameter is:
Spent lye is washed fiber crops: raw ramie was soaked 20～40 minutes under 80～100 ℃ of temperature with the kiering spent lye, add the activator JX-01 of raw ramie weight 1～8% in this kiering spent lye;
Concentrated base soaks fiber crops: the raw ramie that spent lye is washed behind the fiber crops is put into the NaOH aqueous solution that concentration is 40～80g/L, soaked 20～40 minutes under 40～60 ℃ of temperature;
Bank up: normal temperature 2～6 hours;
Described activator JX-01 prescription: hydrogen peroxide (H
2O
2) 60～95%, alkanolamide 1～15%, pure ether phosphate 1～15%, stabilizing agent 1～10%, phosphoric acid regulate pH value in right amount;
Preparation method: alkanolamide, pure ether phosphate and stabilizing agent added in the hydrogen peroxide according to quantity stir, transfer mixed liquor to pH value 3～5 to get final product with phosphoric acid then.
Described stabilizing agent can be ethylenediamine tetra-acetic acid.
The concrete processing step of energy-saving environment-friendly type china grass degumming process of the present invention is followed successively by: dress cage, pickling, washing, spent lye wash that fiber crops, concentrated base are soaked fiber crops, bank up, fiber crops are washed in kiering, boiling water, strike fiber crops, pickling for the first time, rinsing, pickling, washing for the second time, dewater, oil, dry, bank up, dry.
Described boiling parameter is:
In raw ramie weight: water 1000%, boiling-off additive ZL-02 1～4%, waterglass 3～4%, caustic soda 10～14% is put into raw ramie and boiling-off additive, waterglass, caustic soda the water normal pressure and was boiled 2～3 hours;
Described boiling-off additive ZL-02 mixes to pulverize with sodium phosphate trimer 35～75%, fatty alcohol polyoxyethylene ether sulfate 5～30%, isoparaffin anion surfactant 10～30%, sodium carbonate 10～30% and makes.
Other concrete technological parameter of energy-saving environment-friendly type china grass degumming process of the present invention can be:
Pickling: raw ramie is put into the H that concentration is 2～3.5g/L
2SO
4In the solution, under 55 ℃ of temperature, soaked 2 hours;
Boiling water is washed fiber crops: the raw ramie after the kiering is put into running water, and 100 ℃ were boiled 10 minutes;
Strike fiber crops: 5～7 circles;
Pickling for the first time: with concentration is that the aqueous sulfuric acid of 1～1.6g/L was washed 5 minutes;
Rinsing: with concentration is that the clorox of 0.8～1g/L was washed 5 minutes;
Pickling for the second time: with concentration is that the sulfuric acid of 0.4～0.8g/L was washed 5 minutes;
Washing: be washed to pH value 7～7.5;
Oil: above-mentioned operation raw ramie is put into its soft water to the oil emulsion that is added with raw ramie weight 1～1.5%, soaked under 40～60 ℃ the temperature 50～60 minutes;
Bank up: 8～24 hours.
Described oil emulsion can be tea oil phosphoric acid fat SJ-9980.
The characteristics of China grass degumming production technology of the present invention are to the preliminary treatment of pickling fiber crops before kiering, spent lye is washed fiber crops and concentrated base soaks numb three road preliminary treatment by the pickling fiber crops are carried out, make that pickling fiber crops epidermis is softening, colloid activation, fibre swelling, intermolecular bonding energy reduce, thereby the ramie colloid is degraded and stripping in the kiering process fast, and reach the degummed ramie index of quality that routine is come unstuck and produced.COD value reduction by 10%, colourity reduce by 50% in the waste liquid of kiering discharging.
When spent lye is washed numb preliminary treatment, add the activator JX-01 of 0.5～8% new research and development, the activator action principle is an etching raw ramie epidermis, destroys half fiber-lignin molecule chain, the degree of polymerization of the polysaccharide colloid close with cellulosic structure of degrading makes it to be soluble in the alkali lye.
By the pretreated fiber crops in three roads, when kiering, add the boiling-off additive ZL-02 of 1～3% new research and development, the boiling-off additive action principle is to reduce the interfacial tension of kiering liquid, make the alkali lye infiltration evenly, simultaneously chelated metal ions, suspension colloid, washing fiber, raising kiering quality.
The present invention compares with conventional China grass degumming technology, and its advantage foreshortens in 3 hours the normal pressure kiering under the situation that does not increase alkaline consumption, and the pressurization kiering foreshortened in 2 hours, improved one times of kiering output, reduces the steam consumption more than 30%; Kiering flax fibre softness, color and luster be pure white, it is good to open fibre; Reduce twice washing in the kiering process, the water saving of ton degummed ramie is more than 30 tons; Effectively reduce the colourity (reducing about 50%) and the COD value (reducing more than 10%) of waste discharge than conventional waste water than conventional waste water; The degummed ramie cost per ton of employing new technology can be saved 150～200 yuan; Every production line of newly-built China grass degumming factory can be saved about 400,000 yuan of investments.New technology is promoted in the whole nation, and its economical, societal benefits are remarkable.
