Abstract
The invention discloses a bio-enzyme chemical degumming method for jute fiber, comprising the following steps: determining the weight of raw jute; preparing a bio-enzyme aqueous solution; weighting laccase 0.5-5% of the weight of raw jute, mixing with water 12-35 times of the weight of raw jute to obtain a laccase aqueous solution, and regulating the pH value to 4.0-6.0 and the temperature to 40-65 DEG C; impregnating the raw jute into the bio-enzyme aqueous solution; carrying out chemical degumming treatment of the raw jute; carrying out enzyme inactivation treatment of the jute treated by the bio-enzyme aqueous solution; and taking out the degummed jute and drying. The degumming method for the jute by the bio-enzyme, disclosed by the invention, is simple in procedures, and has good xylogen removing effect.
Description
Technical field
The present invention relates to a kind of jute degumming method, particularly relate to a kind of biology enzyme chemical Degumming method of tossa.
Background technology
Because flax fibre has preferably sucting wet air permeability, low static behaviour and good antibacterial characteristics, hemp product more and more receives people's favor, but because flax, ramie price are higher, make hemp product use and be restricted.Jute is the second-biggest-in-the-world cellulose fibre that is only second to cotton, and is cheap, compares with flax, ramie 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 than high several times of flax, adopts conventional Degumming method that tossa is come unstuck, removes the lignin weak effect, so restricted the application of jute in textiles greatly.Chinese patent document CN1232691C discloses the method that a kind of applying biological enzyme comes unstuck to jute; To the tossa processing of coming unstuck, the tossa warp of gained and other fiber are like cotton, chemical fibre blending or interweave and can satisfy the requirement of garment material basically with the biology enzyme of pectase and laccase for this method.But above-mentioned patent documentation disclosed method is desirable not enough to the removal of lignin impurity in the tossa; Clearance is merely about 76%; The content of lignin is still higher in the tossa of gained, need with other fiber like cotton, chemical fibre blending or interweave, if the fabric that adopts the true yellow flax fibre to weave out; Feel is bad, weak effect.
Summary of the invention
Goal of the invention: in order to solve the problems of the prior art, the invention provides a kind of chemical Degumming method that adopts the tossa of laccase, this method can effectively be removed pectin and the lignin impurity in the tossa.
Technical scheme: to achieve these goals, the biology enzyme chemical Degumming method of a kind of tossa of the present invention, this method may further comprise the steps:
(A) confirm the weight of single treatment jute raw ramie;
(B) the configuration biology enzyme aqueous solution: 0.5～5% the laccase of getting jute raw ramie weight is mixed into the laccase aqueous solution with the water of 12～35 times of former jute fiber crops weight, and adjusting pH value is 4.0～6.0, and temperature is: 40～65 ℃;
(C) the jute raw ramie impregnated in kept in the biology enzyme aqueous solution 20～120 minutes;
(D) the jute raw ramie being carried out chemical Degumming handles: get 1～20% the NaOH of jute raw ramie weight and the water of 10～40 times of jute raw ramie weight and be mixed into sodium hydroxide solution; Regulating temperature is 80～95 ℃; To be immersed in the sodium hydroxide solution through the jute raw ramie that the biology enzyme aqueous solution was handled, kept 20～150 minutes;
(E) jute after handling through the biology enzyme aqueous solution being carried out enzyme deactivation handles;
The jute of (F) taking out after coming unstuck is dried.
In sodium hydroxide solution, can add 0.5～5% bleeding agent of jute raw ramie weight in the step described in the present invention (D).
Said bleeding agent is chosen as PST or JFC.
It is right to be included in the step among the present invention (C) before impregnated in the jute raw ramie in the biology enzyme aqueous solution, and the jute raw ramie is carried out preliminary treatment.
Step described in the present invention (D) is carried out the synergy processed steps of banking up before; Said synergy time of handling of banking up is 6～24 hours.
Enzyme deactivation in the step described in the present invention (E) is treated to the high temperature washing or regulates the pH value and carry out enzyme deactivation processing, perhaps both combinations.The temperature of water was 80 ℃～100 ℃ when said high temperature was washed; PH value when adjusting pH value is carried out the enzyme deactivation processing is greater than 10.0 or less than 4.0.
Preliminary treatment described in the present invention is one or more the combination in water-bath, acid bath or the hydrogen peroxide dipping.
When water-bath was adopted in preliminary treatment described in the present invention, bath temperature was 35～75 ℃, and the time is 30～180 minutes.
Use sulfuric acid or acetic acid when said acid bath is adopted in preliminary treatment described in the present invention, temperature is a normal temperature.
Beneficial effect: the present invention has following advantage:
1, the present invention's mode of adopting biological enzyme to combine with chemical method is come unstuck to jute, and biology enzyme is handled in the part pectin and lignin of removing the jute flax fibre, can make the jute internal structure loose; Carry out chemical Treatment then; Treatment fluid can get into tossa inside more easily, more easily tossa is come unstuck, and can reach more than 80%; Can further carry out refinement to tossa, the tossa fineness after the inventive method is handled can reach more than 500 public.
2, the present invention adopts first biology enzyme processing to carry out chemical treatment then, but not first chemical treatment biology enzyme processing then.Because the strong base solution in the chemical treatment have certain damaging action to the fiber in the jute; Jute internal structure without biology enzyme is handled is tightr; If adopt chemical treatment this moment, strong base solution can cause damage to the cellulose in the jute when removing pectin and lignin; Thereby the intensity of tossa is reduced, finally cause the spinnability variation of tossa.And adopt chemical treatment earlier, and can not make the internal structure of tossa become loose, use biology enzyme to handle the effect that does not also reach further refinement tossa then.
