Description

A kind of soap enzyme and its preparation process for denim fabric washing

Technical field

It soaps enzyme and its preparation process the present invention relates to one kind, and in particular to a kind of enzyme of soaping for denim fabric washing And its preparation process.

Background technique

Jeans develop to and have gone through more than 100 years history today, the jeans also overalls development since most At instantly popular fashion dress ornament, almost manpower at least one, an either line is famous, light luxurious brand, fast fashion, chain super City, even night market roadside stands can see the presence of cowboy.Though the difference that price has dozens of yuan not wait to thousands of members, washing Technique but will not all be lacked for one.The technique of existing denim routine has: manual (hanging mill, hand wipes cat's whisker, embroiders), desizing, Ferment stone washing, rinsing (potassium permanganate bleaching, sodium hypochlorite bleaching, hydrogen peroxide bleaching) neutralize and wash, crumple arrangement (i.e. resin Arrange), chromatography, fry snowflake, protect color arrange, soft finish etc..According to the design requirement of designer, washing process can not Equally, have that GARMENT WASH (desizing+softness), ferment wear away (desizing+ENZYME WASH+softness etc.), snowflake washes (desizing+ENZYME WASH+stir-fry snowflake Deng), or even there are also " cowboying races " that a batch chases fashion, buy a genuine jeans, process without any washing, lean on The overall effect that occurs after oneself dress friction, show different personal style.

Denim fabric passes through the development of many years, has from fabric, washing processing technology, chemicals, mechanical equipment etc. Very big variation.Fabric by the single thick and heavy wear-resisting pure-cotton fabric of roving count in the past till now contain Lycra, day A variety of completely new fabric selections such as silk, cotton ramie blended spinning；Processing technology is washed also by common in the past cat's whisker, stone washing, rinsing etc. Embroidering till now, snowflake is washed, gold stamping the new processing technology such as arranges；Chemicals by containing APEO, NPEO, formaldehyde etc. in the past Product not environmentally is changed into the product now without the environmental protection such as APEO, NPEO, formaldehyde, by the biological enzyme of fully biodegradable Preparation substitutes the chemicals of traditional high-alkali, high content of phosphorus, difficult for biological degradation；Then developing faster, Duo Yihuan in terms of mechanical equipment Guarantor, energy conservation, water-saving are developing direction, and rinsing machine is all that elution is integrally full-automatic till now by pervious single wash water function development Change, liquid medicine addition can automation control, reduce human error.The processes such as traditional artificial hand wiping are also swashed gradually at present The radium-shine equipment replacement of light, although radium-shine equipment, at present there is also at high cost, up-front investment is big, factory technics apply jejune shape State, but with the raising of people's environmental protection concept, it is certain to largely come into operation in the near future.Ozone rinsing machine without using Chemicals can save great lot of water resources, and ozone is pure substance, pollution-free, easily be decomposed into oxygen and oxygen atom at normal temperature, can The health risk of operator is reduced, therefore meets the requirement of ecological, environmental protective.Ozone process can also substitute diffusion type chemicals The effect of matter removes and returns dye transfer note on pocket and weft yarn, while without using PP spray and sodium pyrosulfite.In addition, ozone Bleaching agent or N-process can be exempted, to reduce the batch machining time, and reduce the loss to fabric fibre strength.Washing The fast development of equipment is more leading with some enterprise technologies of the country such as Spain, Turkey at present, such as: Jeanologia, Macsaid etc., domestic there are also enterprises, such as: light doctor, gold fortune laser.

Although technology is all constantly updating iteration, new mechanical equipment is also used in investment factory slowly, with regard to mesh Preceding entire washing industry accomplishes the requirement for without using chemicals and reaching washing again without method, and most factory still passes Based on the processing technology of system, still a conduit made of long bamboo oil, desizing enzyme, cellulase, potassium permanganate, sodium hypochlorite, silicone oil, hydroxide are being used The chemicals such as sodium, hydrogen peroxide, washing powder, resist printing powder.It is washed in factory's ferment stone washing technique with acidic cellulase ferment, is neutral fine Wash, acidic cellulase+float stone is worn away, neutral cellulase+float stone is worn away by enzyme ferment for dimension element.Cellulase is applied alone in ferment stone washing Ferment is washed, and part order is extremely difficult to the stereoscopic effect to rocket, and especially American-European order requires the effect three-dimensional sense that cowboy rockets It is eager to excel；And with cellulase+float stone together ferment stone washing, float stone can wear during wearing away and remain in jean Pocket or folding inside front cover are difficult to clear up, uncomfortable to dress, the float stone slag in addition generated after the abrasion of float stone to sewerage very It is unfavorable, sludge cleaning periodically must be carried out to sewerage.The principle that cellulase ferment is washed is exactly that cellulase is utilized to decompose fiber Cellulose fiber, in addition mechanical equipment active force, thus achieve the effect that cowboy rockets, but cellulase decomposes fiber surface, Fibrous inside can be decomposed, therefore cellulase carries out during ferment is washed if controlling bad usage amount and technique, just Cause the dress ornament strength damage of processing excessive out.Although float stone only to fiber surface wear, jeans because sewing because Element, has that local area is partially hard, causes partially hard local serious wear even to be ground rotten, and the problem of float stone maximum is exactly floating of generating Rock ballast can remain in garment pocket, have a certain impact to dress, especially garment for children, and the float stone slag in addition generated is to dirt There are serious influences for water system.For cowboy's processing after spray PP and neutralisation treatment, part factory can carry out washing powder or a conduit made of long bamboo oil again Deng washing analog assistant cleaned, with improve spray the position PP clarity and improve cloth cover releasing pornographic condition, washing powder with And the washing analog assistant such as a conduit made of long bamboo oil has a certain impact to sewerage, and return the dyestuff being stained on clothes there are phosphorus content height, one It is to be difficult to wash down by the auxiliary agent for washing class, therefore ideal definition effect is not achieved in conjunction with fiber.

In summary existing processing method has the disadvantage that: 1, cellulase dosage is excessive or technique is too long, will lead to Fiber strength damage is big, and fabric is tendering serious；2, the cleaning of float stone slag is not clean, can damage to human skin, especially It is virgin；3, float stone slag can block treatment tank, must periodic cleaning, i.e., the operation cost of increase factory also can to production effect and The order period impacts；4, phosphorus content is excessively high, if processing, which is not thorough, will cause water eutrophication, influences ecological environment.

Traditional cowboy's desizing and ferment stone washing technique are carried out in two steps, and first desizing carries out ferment stone washing, patent again ZL200810040257.4 announces a kind of manufacturing process of all-round ferment of energy saving and environment friendly denim, which also discloses Using the all-round ferment of the energy saving and environment friendly denim, under the conditions of 60 DEG C, desizing, ferment is washed and soft three process closes And complete, to simplify process flow, the working time is shortened, has reached energy-saving and emission-reduction, has improved production efficiency, reduces production Cost reduces environmental pollution, the purpose of specification jean water-washing technique, but the invention product is not asked in effect rocketing Topic, but float stone style can not be replaced, and anti-staining effect Shortcomings.Patent ZL201410828847.9 announce a kind of pure cotton and The biological enzyme desizing ferment of the blended denim garment of class containing cotton washes a bath process, which, which also discloses, washes a bath using the desizing ferment Desizing, ferment are washed two procedures and merged by enzyme under the conditions of 40-50 DEG C, and average 100 pairs of jeans of every processing reduce by 3 cylinders in total Water reduces the use of chemical assistant, and reaching reduces COD/BOD, comprehensive to achieve the purpose that " water-saving, energy saving, consumption reduction, emission reduction ", whole A technical process is time saving, simple, easily-controllable, reasonable, generates without harmful toxic matter, and production efficiency significantly improves, and product quality is more Stablize, production overall cost is greatly reduced, but there is no problem rocketing in effect for the invention product, but can not replace float stone wind Lattice, and anti-staining effect Shortcomings.The denim garment of recent development moves back ferment one and bathes efficiently all-round enzyme, patent application 201810835037.4, which announce a kind of denim garment, moves back ferment one and bathes efficiently all-round enzyme and its preparation process, the invention mention cowboy at Clothing move back ferment one bathe efficiently all can enzymatic process desizing, ferment washed into two bath process merge into a bath process, more water-saving, power saving, time saving； Lower using temperature, highest, which only needs 35 DEG C, can reach extraordinary desizing, ferment stone-wash effect；Do not have to elastic polyurethane fiber fabric Have any influence, not will cause jeans in water-washing process become large-sized or local foaming phenomena；Float stone can be replaced, reached The rough flower point style that float stone is washed, reduces the use of float stone, it is possible to reduce since the deposition of float stone slag causes dirt in sewerage A large amount of depositions of water system sludge；The use for reducing float stone, can be improved the service life of washing equipment；Reduce making for float stone With, it can be improved in water-washing process and wasted due to clearing up the float stone bring time, raising washing efficiency, although this method is rising It is all good in colored, anti-staining effect, but strength damage is relatively higher.

Traditional denim in monkey wash and then in being carried out using sodium pyrosulfite and, then with washing powder and an a conduit made of long bamboo Oil is cleaned, then the clarity and cloth cover brightness for reaching the spray position PP with this technique together is cleaned with clear water, but factory Most of washing powder now used is all the very high regular powder of phosphorus content, and a large amount of uses have very big shadow to water environment It rings, and returns and be stained with the dyestuff of cloth cover and be also difficult to wash down by washing powder and a conduit made of long bamboo oil.
