Description
Technical field
A kind of glucoamylase, glucose oxidase, pectase and CBD-lignin peroxidase cotton pretreatment method belong to COTTON FABRIC dyeing and finishing processing pretreatment technology field.
Background technology
COTTON FABRIC has good wearability, is one type of important textiles.But in the growth course of cotton fiber; The material that a certain amount of protective effect arranged; And the material that generates in the bio-metabolic process and cellulose symbiosis are long altogether; These cellulose commensals mainly contain pectin substance, nitrogen substance, waxy substance, natural colouring matter etc., the cotton seed hulls of when stripping cotton fiber, carrying secretly in addition.These impurity are called the natural impurity on the COTTON FABRIC.In addition; Cotton fiber is before spun yarn is woven into fabric; Need be that master, weight account for the slurry about yarn weight 6%-18% with starch at last layer on the warp thread,, guarantee to have high weaving efficiency and good fabric quality to improve brute force, the anti-wear performance of warp thread.But on commensal on the cotton fiber and the COTTON FABRIC warp thread on slurry can influence the wearability and the dyeing and finishing processing characteristicies such as suction, dyeing such as feel, outward appearance, whiteness of COTTON FABRIC; Therefore; In the pre-treatment of dyeing and finishing processing, need to remove, to satisfy dyeing and finishing processing and the needs of taking.This process is called the pre-treatment of COTTON FABRIC.
Traditional pre-treating method of COTTON FABRIC is; Adopt alkali that swelling, dissolution or the amylase of starch based slurry are removed the slurry (destarch) on the fabric to the decomposition of starch size; Utilize alkali that the hydrolysis of fatty acid ester material, nitrogen substance (being mainly protein substance) in pectin, the cotton wax and emulsification, the peptizaiton of surfactant are removed all natural impuritys except that natural colouring matter and cotton seed hulls on the cotton fiber; Improve the water absorbing properties of COTTON FABRIC, this step is called concise.Utilize alkali in the refinery practice to macromolecular degradation of lignin and hydrogen peroxide solution or clorox in the swelling of cotton seed hulls and the cotton seed hulls to natural colouring matter and the decolorization of the cotton seed hulls of swelling remove natural colouring matter and make the decolouring of cotton seed hulls surface; Reach the purpose that improves fabric whiteness, this process is called bleaching.
Therefore, COTTON FABRIC traditional preprocessing process generally is divided into alkali or enzyme desizing, alkali is concise and bleached for three steps, and its typical technological process is: alkali or enzyme desizing → alkali is concise → and washing → bleaching.
COTTON FABRIC traditional preprocessing method technical maturity, treatment effect is good.But also exist fiber (fabric) damage greatly, handle that chroma in waste water is dark, pH value is high, COD value problems such as (generally reaching thousands of to 10,000 mg/L), slurry amount be big have greatly had a strong impact on the quality of COTTON FABRIC, the waste water that discharges simultaneously also severe contamination environment.
To the existing problem of COTTON FABRIC tradition pre-treating method; Since the nineties in 20th century; Both at home and abroad through to the concise big quantity research that carries out of the biology enzyme of COTTON FABRIC; The biology enzyme pre-treating method of COTTON FABRIC has been proposed; Promptly utilize amylase to the decomposition of starch size and alkaline pectase amylase/concise one-step method of alkaline pectin enzyme desizing to the decomposition of pectin; Concise and the hydrogen peroxide bleaching two step method of enzyme desizing of utilizing hydrogen peroxide solution that COTTON FABRIC is bleached again; Perhaps utilize amylase that the enzyme desizing of the decomposition of starch size and alkaline pectase are hydrolyzed to the micro fiber fine hair that cotton seed hulls fragment and COTTON FABRIC link to pectin decomposition and cellulase; Weaken the alkaline pectase/cellulase of cotton seed hulls fragment and COTTON FABRIC adhesion concise with the destruction of hydrogen peroxide solution to the decolouring of natural colouring matter on the cotton fiber and the cotton seed hulls fragment of having made a concerted effort to weaken with the COTTON FABRIC bulk junction, or directly utilize the complex enzyme discoloration of forming by amylase, alkaline pectase and cellulase etc. concise to the destarch of COTTON FABRIC and hydrogen peroxide solution to reach the purpose of pre-treatment.Its typical technological process is: amylase/alkaline pectin enzyme desizing is concise → and hydrogen peroxide bleaching; Or amylase destarch → alkaline pectase/cellulase concise → hydrogen peroxide bleaching, or amylase/alkaline pectase/cellulase complex enzyme destarch concise → hydrogen peroxide bleaching.
Though the method for above-mentioned biology enzyme pre-treatment has good removal effect to the impurity such as pectic substance on starch based slurry, the cotton fiber, and the COD value with weight-loss ratio little to the damage of cotton fiber, fabric low (being merely alkali pre-treatment traditional about 2% reaches about 8%-10%), waste discharge such as is merely about the 10%-30% of traditional alkali pre-treatment at advantage.But a large amount of researchs show that there is two large problems in the handled COTTON FABRIC of this pre-treating method, the one, and wettability of fabrics is poor, and capillary effect is low.Fabric treated basically can not be by water-wet after 100-105 ℃ of oven dry in this way, and capillary effect is 0.Another problem is the poor removal effect of cotton seed hulls fragment, and fabric is after bleaching, and fabric face is also residual to have more cotton seed hulls fragment, has a strong impact on the outward appearance of fabric and the uniformity of dyeing.Cause the reason of this present situation to be, cotton fiber in growth course, can fiber surface form one deck mainly by number of carbons (like C
16, C
18) epidermal area formed of hydrocarbon.This epidermal area ability illumination, anti-rain erosion, thus play the effect of protection fiber itself.This epidermal area is hydrophobic, can not be decomposed by various enzymes such as common amylase, pectase, cellulases.Simultaneously, because the existence of this epidermal area also can have influence on accessibility and the removal effect of the enzyme classes of pre-treatment to various impurity in the cotton fiber.So COTTON FABRIC is after various enzyme pre-treatments, wettability is poor on the one hand, and capillary effect is low, and the clearance of pectin also has only 70%-80% on the other hand, has had a strong impact on its pre-treatment effect.And the cotton seed hulls fragment in the COTTON FABRIC mainly is made up of lignin, cellulose, hemicellulose and tannin etc., complex structure, and quality is hard.Because in above-mentioned biology enzyme pre-treatment; Lacked at caustic soda, high temperature and act on for a long time, lignin is difficult to degraded, depends merely on follow-up hydrogen peroxide bleaching and just has been difficult to only certainly; Particularly low for cotton quality, the more fabric of cotton seed hulls fragment is all the more so.
The present invention utilizes glucoamylase/glucose oxidase, alkaline pectase and CBD-lignin peroxidase three-step approach to carry out cotton pretreatment.
Glucoamylase is claimed carbohydrase again, can starch be produced glucose from non reducing end hydrolyzing alpha-1,4 glucoside bond, and also slowly hydrolyzing alpha-1,6 glucoside bond changes into glucose.Its optimal pH scope is 4.0-4.5, and optimum temperature range is 58-60 ℃.The starch size on the fabric is decomposed in effect through glucoamylase, reaches the purpose of destarch, simultaneously, generates glucose.
The glucose that generates generates hydrogen peroxide (hydrogen peroxide solution) under the effect of glucose oxidase.Glucose oxidase is a kind of oxidoreducing enzyme, but catalysis glucose and oxygen reaction generate hydrogen peroxide solution and glucolactone.The optimum pH of glucose oxidase is 5.6, under the condition of pH4.5-6.5, has good stability.Temperature stabilization scope (30-60 ℃) with broad.The optimum condition of this condition and glucoamylase is very approaching, and both have the condition of well fitting altogether.
The hydrogen peroxide solution that generates plays two effects to cotton pretreatment, and the one, discoloration utilizes the destruction of hydrogen peroxide solution to natural colouring matter on the cotton fiber, improves the whiteness of fabric.Another effect is the hydrophobic layer that can destroy the cotton fiber surface, can improve the wettability of COTTON FABRIC, simultaneously the pectic substance on the cotton fiber is fully exposed, and improves the accessibility and removal efficient of follow-up alkaline pectase to pectin.
The glucolactone less stable that glucose oxidase and oxygen reaction generate, facile hydrolysis generates gluconic acid.Gluconic acid has very strong sequestering power to metal ion, and therefore this method need not to add hydrogen peroxide stabilizer when bleaching.
Because when glucoamylase and glucose oxidase were handled, handling the pH value of bathing was faintly acid-neutrality, temperature is also lower, is generally about 60 ℃, and under such condition, the functioning efficiency of hydrogen peroxide solution is low, and the whiteness of fabric is lower.For hydrogen peroxide solution is played a role, improve the whiteness of fabric, handle at glucoamylase/glucose oxidase, behind the hydrogen peroxide solution that acquisition needs, need be warmed up to 95 ℃ and handle 120min.
Pectase is the enzyme of one type of decompose pectin; Contain in the decompose pectin molecule ester bond between the methoxyl group in the ester of polygalacturonic acid and galacturonic acid; Form the pectinesterase of polygalacturonic acid, the polygalacturonase that cuts off polygalacturonic acid α-1,4 glycosidic bond and generation β-elimination reaction, α-1 in the division polygalacturonic acid; 4 glycosidic bonds generate the pectin lyase of unsaturated sugar etc.Pectase commonly used is an alkaline pectase, 55-60 ℃ of its best use of temperature, optimal pH 8.Simultaneously, because pectic substance between wax and fiber, is bonded in wax on the fiber like " glue ", after pectic substance was removed, the adhesion of wax and fiber can reduce, and therefore, when pectic substance is removed, also had the part cotton wax to be removed.
The main component of cotton seed hulls fragment is lignin, cellulose and hemicellulose.Lignin peroxidase is a topmost component in the whiterot fungi Phanerochaete chrysosporium lignin degradation enzyme system, effectively the degraded of catalysis lignin.The CBD-lignin peroxidase is to contain the cellulose binding domain lignin peroxidase of (cellulose-binding domain is called for short CBD).CBD is usually located at the C-end or the N-end of lignin peroxidase albumen; One side is hydrophilic, and one side is hydrophobic wedge structure, and hydrophobic surface exposes has the aromatic amino acid residue; Can form hydrogen bond; Have the function with cellulose adsorption, can the enzyme molecule be connected on the cellulose, improve the degradation efficiency of lignin peroxidase lignin.
