Abstract
The present invention relates to a boiling method of cotton fabrics by using a glucose oxidase preparation in an enzyme method, which belongs to a compounding technique of a glucose oxidase preparation and the application technical field thereof in the pre-processing technology of cotton fabrics. In the present invention, a glucose oxidase preparation is added when a cotton fabric is boiled by an enzyme method, and the enzyme preparation can generate hydrogen peroxide by using glucose as substrates at the temperature of 60 to 80 DEG C. in the pH value of 6.0 to 8.0, thereby enhancing the boiling effect of the enzyme method of cotton fabrics and being helpful to remove impurities of noncellulose and enhance the wetting property and the whiteness of fabrics treated by enzyme. Compared with cotton fabrics which are not treated by the enzyme preparation, the treated cotton fabrics have higher impurity removing efficiency, high fabric wetting property, high whiteness, etc. Glucose can be obtained from de-sizing products of starch size, and the starch size is reutilized. The present invention has the advantages of energy saving, low energy consumption and favorable environment. The boiling method of cotton fabrics in an enzyme method is better than the traditional high-temperature high-alkali boiling method by that factors in many directions are comprehended.
Description
Technical field
A kind of method of boiling off cotton fabric of using glucose oxidase preparation is the new method that is applicable to the boiling-off of COTTON FABRIC biology enzyme, can improve the performance that biology enzyme is handled the back fabric.Relate to glucose oxidase preparation compounded technology and the applied technical field in cotton pretreatment technology thereof.
Background technology
With biology enzyme COTTON FABRIC is carried out boiling-off, because the mildness of enzyme action condition and the selectivity of enzyme, enzyme is handled the accessibility and the destructive high temperature highly basic that is not so good as of impurity on the cellulose fibre.So when COTTON FABRIC being carried out boiling-off,, can improve the accessibility of enzyme and the clearance of impurity if make the cotton fiber surface be subjected to a certain degree destruction with enzyme.Hydrogen peroxide is a kind of strong oxidizer, controls its consumption, can make impurity in cellulose surface and the fiber such as pectin, wax etc. obtain to a certain degree destruction, thereby can improve the effect of COTTON FABRIC biology enzyme boiling-off.Starch size on the COTTON FABRIC can be degraded to glucose completely by α-Dian Fenmei and glucoamylase, and glucose oxidase can generate hydrogen peroxide by catalysis glucose, is used to promote the boiling-off of fabric.Glucose oxidase and glucoamylase and fabric boiling-off can act under the condition of the low alkali of middle temperature with enzyme, and starch size can utilize again simultaneously.Therefore the energy-conservation province of this method consumes environmental friendliness.
Summary of the invention
The method that the purpose of this invention is to provide a kind of boiling off cotton fabric of using glucose oxidase preparation, the effect of raising boiling off cotton fabric to satisfy the processing request of fabric later process, improves fabric quality.Use the present invention can solve the problem of present enzyme process boiling-off poor effect, when improving the fabric product quality, energy-conservation province consumes, environmental friendliness.
Technical scheme of the present invention: when boiling off cotton fabric, in boiling-off is bathed, add glucose oxidase preparation, with glucose is that substrate generates hydrogen peroxide, promote the boiling-off of COTTON FABRIC, the source of required substrate glucose is directly to add glucose in boiling-off is bathed, or adding amylase degradable starch slurry obtains glucose in boiling-off is bathed, boiling-off is bathed and is consisted of: scouring enzyme preparation (alkaline pectase) 0.3～1.5g/L, glucose oxidase preparation 0.3g/L, glucose 3g/L or L-2000 amylase 3g/L, penetrating agent JFC 8g/L (Yixing City army reaches Chinese workers factory product), boiling house condition is: the mass ratio that COTTON FABRIC and boiling-off are bathed is 1: 20, pH6.0～8.0, at 60～80 ℃ of boiling-off 60～120min, used glucose oxidase preparation is by glucose oxidase and glucoamylase is composite forms, and its mass ratio is 1: 0.2～0.4.
Beneficial effect of the present invention: the present invention can improve the effect of boiling off cotton fabric, help the removal of non-cellulosic impurity, pectin, wax etc. there is destruction preferably, can improve the accessibility of other enzyme preparations and fabric in the enzyme process boiling-off, improve enzyme and handle back wettability of fabrics and whiteness.Handling removal of impurity, wettability of fabrics, the whiteness geometric ratio of back COTTON FABRIC does not use this enzyme preparation to improve a lot.Glucose can obtain from starch size destarch product, and starch size is utilized again, energy-conservation province consumption, and environmental friendliness, the factor of comprehensive each side uses boiling off cotton fabric of the present invention to have more advantage than the high-alkali boiling-off of conventional high-temperature.
