Abstract
The invention relates to a helicase which is a compound enzyme extracted from a snail crop or a snail digestive tract, the helicase mainly contains twenty kinds of enzyme including cellulose, pectinase, amylase, prolease and the like and is a byproduct in comprehensive utilization and development of snails, however, in the practical processing, the internal organs of the snail are always discarded, so that great waste of enzyme resources is caused. The helicase is a good compound enzyme system containing the pectinase, the amylase and the cellulose; the helicase which is a natural compound enzyme system is applied to a biological refining process of a cotton woven fabric to remove pectin, waxiness and other impurities in cotton fiber under the hydrolytic action of the helicase, therefore, the purposes of improving the wettability and the whiteness of the cotton fabric are achieved. The helicase is adopted for refining the cotton fabric, the helicase has the environment-protecting and energy-saving characteristics, the snail processing byproducts can be comprehensively utilized, the requirement for the current sustainable development is met, and the comprehensive development of the dyeing and finishing industry and the processing industry for snail agriculture products are facilitated.
Description
Technical field
Utilize glusulase cotton fabrics to be carried out to a method for Bio-Pretreatment, belong to COTTON FABRIC dyeing and finishing processing pretreatment technology field.
Background technology
It is food that occurring in nature snail mainly be take blade and the tender shoots of plant, therefore, in long-term evolutionary process, has produced the biology enzyme that can digest various plant components in its body.1898, Bi Deerman found to exist a large amount of enzymes such as cellulase, hemicellulase, seminase and proteolytic enzyme in the glandula digestive of snail.Nineteen twenty-two, victory adds first separated from the glandula digestive of snail and has extracted this mixed enzyme, and is referred to as " glusulase ".China scientific worker also in 1974 respectively from Achatina and the brown glandula digestive with collar extension spiral shell, successfully separation and extraction glusulase.At present, glusulase has tentatively been realized suitability for industrialized production at home.
According to research reports, average every milliliter of snail digestive juice can extract 10-130mg dry state enzyme preparation.Primary Study shows mainly to contain in glusulase 20 plurality of enzymes such as cellulase, pectase, amylase and protease.What wherein content was maximum is respectively cellulase and pectase, and these two kinds of enzymes are the most frequently used enzyme preparations of Bio-Enzyme Pretreatment of Cotton Fabric.Wherein, cellulase can be removed impurity on fiber and the fine hair of fabric face by hydrocellulose, improves hygroscopicity and the fineness of fabric; Pectase can decompose pectin contained in cotton fiber, improves the wettability of fabric.Other contained enzymes of glusulase in addition, as: hemicellulase, seminase and protease etc. can with cellulase and pectase synergy, the impurity on cotton fiber also will be played to certain removal effect as hemicellulose and protein etc.Therefore,, by being rich in the biology enzyme pre-treatment of the glusulase of plurality of enzymes component for COTTON FABRIC, can produce good scouring result.
In addition,, in recent years along with the development of biological enzyme technology, the biology enzyme of COTTON FABRIC is concise, and also from single enzyme, concise to develop into complex enzyme concise.This is mainly because enzyme has selectivity, and single enzyme can only be removed certain impurity on fabric, so the concise improvement to fabric property of traditional single enzyme is limited, fabric property promotes comprehensive not.Therefore, adopt complex enzyme system to carry out the concise concise inevitable development trend of following biology enzyme that become to fabric.Glusulase is a kind of so concise natural complex enzyme system of COTTON FABRIC that meets just.So it is concise to adopt this enzyme to carry out COTTON FABRIC, not only there is the environmental protection of biological treatment, the feature such as energy-conservation, and can fully utilize the accessory substance of snail processing, be conducive to the comprehensive development of dyeing and finishing industry and snail processing of farm products.
Summary of the invention
The present invention is incorporated into this natural compound concise enzyme system of glusulase in cotton fabrics pretreatment process, utilize the multiple biology enzyme components such as the contained pectase of glusulase, cellulase, amylase and protease to carry out Bio-Pretreatment to cotton fabrics grey cloth, remove the contained impurity such as pectin, wax, starch size, lignin and pigment on cotton fiber, finally reach the object that improves COTTON FABRIC wettability and whiteness.Adopt the present invention not only can solve the poor problem of single enzyme scouring result, and can improve the comprehensive utilization ratio of snail processing byproduct, promote the sustainable development of heliculture industry.
Main solution of the present invention:
A kind of technique of utilizing glusulase to carry out Bio-Pretreatment to cotton fabrics mainly adopts semi-continuous rolling and piling biology enzyme method for refining.Its technological process mainly consists of the following components: first destarch cotton fabrics carries out hot water or low alkali preliminary treatment, pad afterwards the concise liquid of glusulase and be incubated and bank up, finally by overheated washing (having the enzyme effect of going out concurrently), room temperature washing, dry, finally complete the bioanalysis pre-treatment of cotton fabrics.

Low alkali preprocess method: the cotton fabrics after destarch is first padded to (alkali lye formula: NaOH 10g/L, non-ionic surface active agent 1g/L in the alkali lye of 90 ℃, two soak two rolls, pick-up 100%), time 2-5s; bath raio 1: 50; 120 ℃ of high temperature steaming 1-5min afterwards, last room temperature washing 3 times, dries (pick-up 100%).
2. glusulase is concise
(1) configuration of enzyme liquid: glusulase solid (Achatina product glusulase) is first melted with 40-50 ℃ of warm water, join afterwards in the buffer solution of being prepared by sodium hydrogen phosphate and citric acid, the nonionic or the anion surfactant that add 0-2g/L, stir and filter again.The concise liquid concentration of glusulase of final configuration is 2-10g/L, pH value 4.5-6.5.
(2) enzyme is processed: pretreated fabric is padded to glusulase liquid with the speed of a motor vehicle of 10-20m/min, and the mode of padding is two to soak two and roll, and the temperature of padding enzyme treatment fluid is room temperature to 65 ℃, and pick-up is 80%-100%, rolls laggard windrow and puts.
3. insulation is banked up
Temperature has material impact to the scouring result of enzyme, and cotton fabrics need be banked up after padding enzyme liquid under 50-65 ℃ of unsaturated steam condition, and the time, temperature was high between 30-90min, and the time of banking up is short, and the low time of banking up of temperature is long.
4. washing and oven dry
The fabric of heap postpone need be first with the hot wash of 95 ℃ of left and right 1 time, about 5-20s of time, this process not only can be removed most of impurity of enzyme processing but also glusulase is had to kill activity, prevent the continuation hydrolysis of enzyme to COTTON FABRIC, after hot wash, fabric with room temperature washing 3 times, is finally dried again.
