Description
Technical Field
The invention relates to a fabric treating agent, in particular to a denim garment fermentation-bath high-efficiency totipotent enzyme and a preparation process thereof.
Background
When considering the most popular single product in the fashion world, I want to Momo in non-jeans. Jeans have been far beyond the category of fashion and become the most common basic style in people's wardrobes, and may be the only fashion item breaking the hierarchy fence, so people can buy jeans with different prices in front-line large brand, light luxury brand, fast fashion brand shop, chain supermarket, wholesale market and even roadside stall of the night market according to their own consumption ability. The jeans sold at thousands yuan and the jeans sold at nineteen yuan have no great difference in appearance, the most popular fashion factors of water washing, cutting and hole breaking … … are all the same, and the common point is that the production of each jeans needs to consume a large amount of water resources. Media has reported that a certain brand of jeans in 2007 evaluated the resources required to make a style of jeans, and as a result, it was a surprising finding that jeans were almost water-made, from cotton to cotton and then to a water washer, that a jeans life would naturally require 3480L of water, and that if calculated as two liters of water needed to be taken by an adult per day, the water consumption of a jeans was sufficient to meet the water consumption of an adult for nearly five years.
The conventional procedures of washing the jeans by water in the prior art comprise: manual (hanging grinding, manually wiping cat whiskers, pricking flowers and the like), desizing, enzyme stone grinding and washing, rinsing (potassium permanganate bleaching, sodium hypochlorite bleaching and hydrogen peroxide bleaching), neutralization washing, crumpling finishing (namely resin finishing), chromatography, soft finishing and the like. The pretreatment desizing process is mostly hot water desizing, desizing enzyme desizing, alkaline oil desizing, alkali desizing, oxygen bleaching desizing, desizing scouring enzyme desizing and the like, and the treatment temperature is different from the normal temperature to 80 ℃; the treatment time varies from 10 to 30 minutes. The ferment stone-milling process comprises acid cellulase fermentation washing, neutral cellulase fermentation washing, acid cellulase and pumice stone milling washing, and neutral cellulase and pumice stone milling washing. The existing desizing and enzyme stone grinding processes have certain defects, and textile size on the fabric cannot be completely removed by hot water desizing and alkaline oil desizing, so that the fabric feels hard; the alkaline desizing and the oxygen bleaching desizing can effectively remove the sizing agent on the cloth surface, but the strong damage to the fiber is large, the desizing COD emission is high, and the environmental impact is large; desizing enzyme desizing can effectively decompose starch size, but cannot decompose chemical size and cannot remove impurities such as pectin and the like on yarns; desizing and scouring enzyme desizing can effectively decompose starch slurry and can remove a part of chemical slurry, but the desizing and enzyme stone washing processes are carried out step by step, so that the water consumption is high and the energy consumption is high. The enzyme stone-milling washing is singly washed by the cellulase enzyme, partial orders are difficult to achieve the three-dimensional effect of the flowering, and particularly European and American orders require the effect of the denim flowering to be strong in three-dimensional sense; and cellulase and pumice are used together for enzyme stone grinding and washing, the pumice is abraded in the grinding and washing process and remains in pockets or folds of the jeans wear to be difficult to clean, so that the jeans wear is uncomfortable, and the abrasion of the pumice is very unfavorable for the subsequent sewage treatment. The combination of the desizing and enzyme stone-milling methods has the following disadvantages: 1. the desizing rate is not high, and the hand feeling is hard; 2. the COD is discharged highly, and the environmental impact is great; 3. strong damage to the fiber is large; 4. the impurities such as pectin and the like on the yarns can not be completely removed, and the definition of sand positions is not enough; 5. the pumice slag is difficult to treat, so that the large amount of sludge in a sewage system needs to be treated frequently; 6. the step-by-step process has large water consumption, high energy consumption and no energy conservation.
The traditional denim desizing and enzyme stone-washing processes are carried out in two steps, desizing is carried out firstly, then enzyme stone-washing is carried out, patent ZL200810040257.4 discloses a manufacturing process of an energy-saving and environment-friendly type omnipotent enzyme for denim washing, the invention also discloses a process for combining three procedures of desizing, ferment washing and softening by using the energy-saving and environment-friendly type omnipotent enzyme for denim washing at the temperature of 60 ℃, so that the process flow is simplified, the working time is shortened, and the aims of saving energy, reducing emission, improving the production efficiency, reducing the production cost, reducing the environmental pollution and standardizing the denim washing process are fulfilled. Patent ZL201410828847.9 discloses a biological enzyme desizing, fermenting and washing one-bath process for pure cotton and cotton-containing blended jean garments, and the invention also discloses a biological enzyme desizing, fermenting and washing one-bath process which combines two procedures of desizing and fermenting and washing at the temperature of 40-50 ℃, wherein 3 cylinders of water are reduced in total for processing 100 jeans on average, the use of chemical auxiliaries is reduced, and the COD/BOD is reduced; the purposes of water saving, energy saving, consumption reduction and emission reduction are comprehensively achieved, the whole process is time-saving, simple, easy to control and reasonable, toxic and harmful substances are not generated, the production efficiency is remarkably improved, the product quality is more stable, and the comprehensive production cost is greatly reduced. However, although the two one-bath processes have lower temperature and better effect compared with the two-bath process, the process temperature needs to reach 40-50 ℃ or even 60 ℃, pumice stone is still needed for grinding and washing, the style of pumice stone grinding and washing cannot be replaced, the sludge in a sewage system is difficult to clean due to the use of pumice stone, and the pumice stone residues are remained on clothes and cannot be cleaned cleanly, so that the wearing comfort is not good. The two one-bath processes are not very ideal for the anti-staining effect of the jean pocket cloth and the cloth cover.

The desizing mechanism is that the 'active site' of the enzyme is in extremely close contact with any point of a starch molecule, a three-dimensional form existing in the active part of the enzyme and a specific electron combination enable one 'chain 2 bond' in the starch molecule to be distorted into an unstable state, the unstable bond of the starch is broken due to hydrolysis in an extremely short time, the enzyme molecule rapidly moves to another starch molecule segment, a complex is formed again, hydrolysis reaction is carried out, and finally, the starch slurry is completely dissolved.
The enzyme activity of the neutral low-temperature cellulase is 100000-150000U/ml, preferably cellulase B866 provided by Novoxil; it is low-temperature neutral cellulase and other effective compound through gene modification, and has very high activity at low temperature. The fermentation washing mechanism is that cellulose fiber is hydrolyzed into glucose through the synergistic action of beta-1, 4-endogluconase, beta-1, 4-exo-glucosaccharase and beta-glucosidase, and short hairiness on the surface of the fiber is finally removed by the mechanical action of equipment. Because the jeans are dyed by the indigo dye, the indigo dye belongs to ring dyeing, only one layer of the surface of the yarn is colored, the yarn core is white and is not colored, and the white core is leaked after the surface of the yarn is etched under the action of cellulase and mechanical action, so that the blue-white contrast effect, namely the pattern effect, is achieved.
The enzyme activity of the pectate lyase is 30000-80000U/ml, is a commercial product and is selected from products provided by Dupont
EcoScour pectate lyase, which belongs to the group of lyases and in particular to the class of carboxolytic enzymes acting on polysaccharides.

The pectate lyase is combined with the alcohol ether auxiliary agent to remove non-cellulose impurities and improve the surface wettability and water absorption of the cotton fabric.
In the liquid enzyme: the alcohol ether is isomeric tridecanol polyoxyethylene ether; is a commercial product, and is selected from isomeric tridecanol polyoxyethylene ether of E-1302/E-1306/E-1308/E-1310 type provided by Heian petrochemical industry, and the like. The series products are easy to disperse or dissolve in water, and have excellent wettability, dispersibility, permeability and emulsibility. A small amount of the product is added into the pretreatment formula, so that an excellent refining effect can be obtained. In the textile industry, as a component of detergents, emulsifiers and scouring agents. The emulsion has a special emulsifying effect on amino silicone oil and dimethyl silicone oil, can improve the effect after use, has less dosage than common silicone oil emulsifiers, is more stable, has extremely strong permeability, and can permeate into the fiber, thereby obtaining more satisfactory soft hand feeling. Does not contain benzene ring structure, so the prepared product becomes a new generation environment-friendly product.
The defoaming agent is a non-silicon defoaming agent. Is a commercially available product selected from Ogao
The serial non-silicon defoaming agent is a non-silicon defoaming agent of a hydrophilic medium system, does not cause silicon spots to remain on the walls of the tank because of not containing organic silicon components, and is easy to clean equipment.
Among the solid enzymes:
the enzyme activity of the neutral low-temperature cellulase is 3000-8000U/ml, preferably cellulase A888 provided by Novitin company, which is low-temperature neutral cellulase which is subjected to gene modification and other effective compounds, and has extremely high activity under the low-temperature condition. The fermentation washing mechanism is that cellulose fiber is hydrolyzed into glucose through the synergistic action of beta-1, 4-endogluconase, beta-1, 4-exo-glucosaccharase and beta-glucosidase, and short hairiness on the surface of the fiber is finally removed by the mechanical action of equipment. Because the jeans are dyed by the indigo dye, the indigo dye belongs to ring dyeing, only one layer of the surface of the yarn is colored, the yarn core is white and is not colored, and the white core is leaked after the surface of the yarn is etched under the action of cellulase and mechanical action, so that the blue-white contrast effect, namely the pattern effect, is achieved.
The enzyme activity of the decontamination cellulase is 10000-50000U/ml, and the decontamination cellulase endo 3.0T provided by Novitin is preferred. The enzyme preparation and the indigo dye have certain affinity, the indigo dye dissolved in the aqueous solution is brought to the surface of the fiber together in the process of the action of the enzyme preparation and the cellulose to cause the rewetting, and the decontamination cellulase has the capability of reducing the affinity of the enzyme preparation and the indigo dye, so the effect of reducing the rewetting is achieved.
Among the solid enzymes:
high-performance environment-friendly dye-proofing powder: the adhesive is prepared by mixing fatty alcohol-polyoxyethylene ether and a hydrolysate of a styrene-maleic anhydride copolymer according to the mass ratio of 1:1-3, wherein the fatty alcohol-polyoxyethylene ether is tallow fatty alcohol polyoxyethylene ether, and the mass ratio of the mass content of styrene to the mass content of maleic anhydride in the hydrolysate of the styrene-maleic anhydride copolymer is 1: 1-10; is a stain blocking powder as disclosed in patent application 2017107026256.
