Description
Technical field
The present invention adopts special biological enzyme formulation (pectase, cellulase, lipase, protease, laccase, zytase, dextranase, catalase etc.) and the composite a kind of textile auxiliary made of environment amenable efficient surfactant and corresponding treatment process, is suitable for the biochemical pre-treatment of carrying out of cellulose fibre or its BLENDED FABRIC.Adopt the later cellulose fibre of this method pre-treatment or its blended product can satisfy dyeing, stamp or the back arrangement processing in road, back well.
Background technology
The dyeing and finishing production process is the wet process process of textiles, always is that industrial production is made one of pollution sources discharging rich and influential family in the processing industry.Dyeing and finishing is to one of negative influence of the maximum of environment, from traditional pre-treatment processing of cotton fiber, yarn, fabric or its blending product.
This pre-treatment comprises uses the bleaching process of oxidizer treatment with NaOH, chelating agent and the heat treated kiering process of surfactant solution, and the mercerising process that adopts concentrated base to handle.
Raw cotton fiber is a kind of plant tissue, and it is made up of the secondary film and covering nascent film and the epidermis thereon that with the cellulose are main component, and the impurity of raw cotton fiber mainly is present in nascent film and the epidermis.Be present in the impurity in the raw cotton, different because of the difference in the kind of cotton, the place of production, be generally the 4-5% that cotton fiber is formed.Cotton is concise to be before process such as fabric bleaching, dyeing, and to remove these impurity, improving hygroscopicity of fabric is the process of purpose.No matter wherein bleach product or coloured prod are all necessary through the kiering process.
Concise process typically uses a large amount of alkali and surfactant, carry out high-temperature process, make cotton accompaniment decomposition, emulsification and remove, for this reason, must wash with acid neutralization and a large amount of water, therefore salt dense in the waste liquid rises the BOD in the waste liquid, makes simultaneously that fibre weight reduces, intensity decreases.The whole world has 42,000,000,000 pounds of cotton fibers will carry out pre-treatment every year approximately at present, and obviously, the pre-treatment process can produce a large amount of waste water, serious environment pollution, and the arch-criminal is NaOH and its salt.
When starting green whirlwind on the current International Textile market, the environmental protection textiles has become the big problem of one in the trade.The management work of environmental protection aspect is no longer only accepted by developed country, developing country also begin now to note weaving and other industrial process to the influence of environment, purpose is chemicals is reduced to bottom line to the influence of waste water.Along with the continuous expansion of enzyme preparation kind, the cultivation of enzyme, production and purification technique are updated and are improved, and make the application of enzyme in textile and dyeing industry constantly obtain new achievement, and also the green production for textiles provides certain possibility.
Enzyme has the high and strong characteristics of selectivity of catalytic efficiency under temperate condition, in the correlative study at home and abroad, the researcher selects for use different enzymes to handle according to different accompaniments as removing object, finally reaches the purpose of removing impurity.
Part Study person adopts cellulase and pectase to handle cotton fiber both at home and abroad, utilize their cooperative effect, be that pectase decomposes the pectin in the cotton fiber, cellulase decomposes the cellulose macromolecule in the primary cell wall, cotton fiber surface impurity and part primary cell wall are removed, reached concise purpose.Wherein, cellulase is a kind of complex enzyme that contains mutual synergistic various ingredients, and it is mainly finished by three parts the effect of cellulose fibre: C
xEnzyme, it acts on the crystalline portion of fiber; C
1Enzyme, its texturized fiber element acts on the unformed part of fiber, and finally forms the product of solubility; Beta-glucosidase, it acts on and cellobiose, three carbohydrate materials, makes them finally be decomposed into monose.
The Wang Xianying of Textile Engineering College, Beijing Integrated Univ. (concise theory of COTTON FABRIC enzyme and effect analysis, printing and dyeing, 1997,10,5-9) utilize these two kinds of enzymes that cotton fiber is carried out pre-treatment, and the cotton combing knitted fabric after concise is dyeed with natural colouring matter, and this technology can change operating environment, reduce environmental pollution.The technical recipe that enzyme is washed is: cellulase 2% (w.o.f.), pectase 4% (w.o.f), pH are 4.5, the time is 10min, bath raio 1: 10, and the washing condition is 90 ℃, 10min, uses the clear water washing at last again.
(the Application of biotechnology in the Pre-treatmentProcesses of Textiles COLOURAGE ANNUAL of Co., Ltd is bleachinged and dyeing in the Ren Xuehong of Southern Yangtze University and reform, 1998,75-85) pre-treatment process of cotton poplin fabric is inquired into, destarch, the kiering that enzyme is handled and be that the technology of kiering compares after the cold batching process in a step and the first destarch, investigated the optium concentration that cellulase and pectase mix mutually, and the influence that enzyme is handled of time, temperature, pH value, bleeding agent consumption.Filtered out technological effect preferably treatment fluid composition and be applicable to the pre-treatment process of actual production.
Youlo.Hsieh and Lisa Cram (Proteases as Scouring Agents for Cotton, TEXTILE RESEARCHJOURNAL, August 1999,590-597) with the digesting agent of protease as cotton, though they think that cellulase can improve hygroscopicity of fabric, but the weightless degree of strength loss and fabric is higher, and also there is this defective in the pectase that contains cellulase.Consider that the content of protein in impurity is higher, adopt proteolytic enzyme to make digesting agent, cause position different of effect according to proteolytic enzyme and be divided into outer proteolytic enzyme and internal protein hydrolase.The author has selected for use ten kinds of protease to do experiment, and elder generation to through the pretreated fabric effect of boiling water short time, found that almost can not improve wettability, even raising is arranged slightly, deviation is also very big with four kinds of protease.By changing pretreated condition, discovery can improve the wettability of fabrics energy, if use the most effective enzyme under optimized condition, can make the fabric low (factory) of angle of wetting than conventional kiering, but is higher than the angle of wetting of the fabric of laboratory kiering.The time that Protease Treatment is handled than the complex enzyme of cellulase/pectase is short, temperature is low, weightlessness is little, and spendable pH value scope is big.
The effect of pectase in cotton is concise now is subjected to the attention of more and more researchers, and protopectinase and alkaline pectase also are the focuses of studying recently except common pectase.
K SAWADA, S TOKINO and M UEDA (Bioscouring of Cotton with PectinaseEnzyme, JOURNAL of SOCIETY OF DYERS AND COLORISTS, 1998,333-336) wait the human pectase to carry out biological kiering, merely with the water imbibition of the COTTON FABRIC of pectase kiering with traditional compare relatively poor, if thereafter with hot water treatment then effect is poorer, reason is the existence of wax.The kiering ability of pectase system can increase greatly by adding mixed surfactant and D-limonene, and its kiering effect can reach the concise effect of tradition, is having wax amount remaining in the presence of surfactant and the limonene obviously to reduce.But the shortcoming of this kind kiering is the dense of the long or enzyme that uses of kiering time.By discovering, can promptly add surfactant and make it to form micella in isooctane by using little micellar system, enzyme is arranged in the water of micella, this moment enzyme active constant even be higher than the activity of the enzyme under the general condition, the removal of wax mainly is because of organic solvent and micellar system.After this system handles, the water imbibition after the water imbibition of fabric and the traditional alkali treatment is suitable, and when handling pectic substance concentration, the time of required enzyme all reduce, but exist the problem that impurity utilizes again of how from organic matter, removing simultaneously.
Also report relevant for pectase and its relatively more successful application in cotton fiber refining, because pectin molecule combines with calcium magnesium and iron plasma, cell wall polysaccharides such as cellulose and hemicellulose and pectin molecule produce covalent bond, the hydroxyl in the pectin molecule and the constituent of cell membrane form ionic bond, pectin molecule to each other and the physics between other compositions twine, and pectin is existed with the form of protopectin, so carry out kiering with pectase, the result shows that the wettability of biological kiering is not second to conventional kiering, the free amount of pectic substance is approximate even be higher than conventional kiering, biological concise fabrics feel soft and abundant, uniformity aspect and conventional boiling-off indifference distance in aspects such as dyeability and dyeing, the brute force of biological concise back fabric is than chemical concise height, aspect the matching of the processing of the cellulase of back, the result of the cellulose treatment mitigation more concise of biological concise fabric than chemistry, the author has noted the cultivation possibility of enzyme in the selection of enzyme, security, stability, and price.
In the research department of Japanese slope Ben Long company, monomer separation has gone out several protopectinases (PPASE).PPASE is the general name that the insoluble protopectin of catalysis decomposites the enzyme of free water dissolubility pectic substance, they are used for the concise of cotton fiber with PPASE, according to its mechanism of action, can be divided into A, B two classes: the A type can cut off polygalacturonic acid moieties in the protopectin, and polygalacturonic enzyme, pectic substance lyase, pectate lyase belong to this type of.Type B decomposes the part beyond the polygalacturonic acid, is the enzyme that makes water soluble pectin matter free, and Arabic enzyme, sandlwood galactolipin aldehydase belong to this type of.The cotton yarn that the result handles with protopectinase can reach the degree of exposed fiber cellulose fiber, and the scouring result of gained is identical with the NaOH scouring result.In addition, protopectinase is inoperative to cellulose, thus can handle back fibre strength reduction by inhibitory enzyme, and also biological concise fabric can not have specking dyeing, and tinctorial yield is than chemical concise fabric height.But the enzyme that the shortcoming of this technology is the cost height, also should develop heat resistant type makes to move back and boils and can reduce cost in a step.
Novo Nordisk (Alkaline Pectinase:an Eco-friendly Approach to Cotton Preparation, TextileAsia, May 1999, the success recently of scientist 83-85) isolate alkaline pectase, this pectase Applicable temperature is about 55 ℃, the pH value is about 9.5, the service condition gentleness, good stability can and be used with chelating agent and wetting agent.Aspect the water imbibition of the fabric of using alkaline scouring and the biological kiering of this kind, there is not marked difference, there be not tangible difference aspect dyeing and the migration property yet, and the feel of fabric is than the softness of conventional process, to having carried out shop test with alkaline pectase, obtained to be equivalent to the water imbibition of conventional kiering, cost is lower than conventional pre-treatment, and fabric feeling is soft.
The scientific research person of Japan (enzyme of tranid colloid decomposes, the printing and dyeing collected translation, and 1997,8,68-74) on decomposing the basis of tranid colloid, pectase studied the utilizing again, piece together of enzyme with the processing of destarch enzyme, to chromatic influence, waste liquor contamination load etc.Show that (1) is along with the used time decreased of pectic substance is removed in the increase of enzyme concentration; (2) in order to piece together with making work simplification with amylase, the amylase of discovery inactivation has inhibition to the removal speed of pectic substance, still without affirmation, but thinks that the activity of the divalent calcium ion pair pectase in the amylase has inhibitory action; (3) enzyme still has active the existence after handling once if the concentration of enzyme is higher, replenishes some enzymes in waste liquid, just can reuse; (4) find that by dye test the outward appearance of the concise fabric of enzyme is with yellow slightly, vividness is poor, on dye the concentration height, fastness is better; (5) contrast test that washes machine and dyeing machine with water shows that pectase does not need effects such as mechanical agitation and friction to the removal of pectic substance; (6) the organic matter pollutional load of scouring waste comes from cotton natural component, and with the concise COD height of comparing of high pressure, BOD is low, but the waste liquid organic pollution load that contains the enzyme of buffer solution increases on the contrary; (7) enzyme is concise can remove supracutaneous pectic substance exposed fiber winding layer; (8) cost is higher.
For the requirement of kiering traditional handicraft, also to remove the cotton seed hulls on the grey cloth, this problem is perplexing the research worker for a long time.It is generally acknowledged that cotton seed hulls mainly is made up of lignin, some think that its basic structure is the beta-hydroxy pine camphor, and another kind thinks that its basic structural unit is reed base glycerol β-guaiacyl ether.Sodium chlorite, chlorine and hypochlorous acid and salt thereof are the medicaments of effectively removing lignin, think normally that parent's electricity is attacked to reoxidize earlier to change into the solubility thing again, or are chlorinated into chlorlignin's stripping under the alkali effect.Byrne proposes " be applied to zytase now a final solution may be provided ".
And EMILIA CSISIAR GYORGY SIAKACS and ISTVAN RVSINAK etc. combine the cellulosic enzyme processing of cotton kiering, chemical solutions was penetrated into the effect in the cotton seed hulls when they adopted spinning blowing room waste material and adopt the plain enzyme of commercial fibre to be handled by enzyme with research, and cellulase is considered effect of weightlessness to be worth doing to shell.Simultaneously, also studied cellulase on COTTON FABRIC, removing the effect of cotton seed hulls.When only cotton seed hulls being studied, cotton seed hulls has certain weightlessness after the cellulose treatment, weightless increasing after the soda boiling can reach 80% degraded, when the method is used for COTTON FABRIC again, the author has thought cellulase pre-treatment hydrolysis makes cotton seed hulls pay micro fiber on fabric, become the shell bits that freely float,, find to make fabric face not have cotton seed hulls and exist in addition traditional cotton kiering, and inner cotton seed hulls amount also reduces greatly, and whiteness improves 10%.
In sum, adopting biology enzyme that COTTON FABRIC is carried out having carried out number of research projects aspect the biological pre-treatment, and, many significative results obtained.But many achievements in research only rest on the laboratory result stage, can not carry out commercial application basically, and various achievements in research all exist some defectives more or less.In order to obtain the technology that COTTON FABRIC is carried out biochemical pre-treatment of comparative maturity, and then the multicomponent fibre lining is implemented the biochemical pre-treatment of short flow process process, satisfy the needs of industrialization, the researcher of this seminar is by great deal of laboratory tests work and continuous setting-out work at the factory scene, finally obtained and to be applied to the achievement that industrialization is produced: prepared multiple biology enzyme (pectase, cellulase, lipase, zytase, dextranase, laccase etc.) and surfactant be composited, be fit to cellulose fibre with and the short flow process ecology pre-treatment auxiliary agent and the corresponding pre-treatment technology of the multicomponent fibre of blending.
Develop environment amenable ecological pre-treatment auxiliary agent, on the one hand, can shorten the processing time, enhance productivity, reach water saving, energy-conservation and reach the purpose of environmental protection; On the other hand, can so that fabric lining powerful impaired in the pre-treatment process be reduced to minimum, thereby make the quality of product that significant improvement be arranged, and improved yield rate and reappearance.
The research characteristic of this project is that the pre-treatment auxiliary agent of being developed not only is suitable for the short process pretreatment of cellulose fibre, substitutes traditional pre-treatment process that serious environmental pollution is arranged, and meets the requirement of cleaner production; And the pre-treatment of the multicomponent fibre lining that this auxiliary agent can be suitable for becoming more and more popular now solves the problem that adopts conventional pre-treating method cann't be solved.
