Txog tam sim no, nyob rau hauv textile printing thiabdyeing, cellulase, amylase, pectinase, lipase, peroxidase thiab laccase / glucose oxidase yog rau enzymes loj uas nquag siv.
1. Cellulase
Cellulase (β-1, 4-glucan-4-glucan hydrolase) yog ib pawg enzymes uas degrade cellulose los tsim cov piam thaj.Nws tsis yog ib qho enzyme, tab sis ib qho kev sib koom ua ke ntau cov enzyme system, uas yog ib qho enzyme complex.Nws yog tsim los ntawm excised β-glucanase, endoexcised β-glucanase thiab β -glucosidase, nrog rau xylanase nrog kev ua haujlwm siab.Nws ua rau cellulose.Thiab nws yog cov khoom uas tau muab los ntawm cellulose.
Nws tseem hu ua polishing enzyme, clipping tus neeg saib xyuas thiab cov ntaub npuag tshem tawm tus neeg saib xyuas, thiab lwm yam.
2. Pectinase
Pectinase yog ib qho enzyme complex, uas yog hais txog ntau yam enzymes uas decompose pectin.Nws feem ntau muaj pectin lyase, pectinesterase, polygalacturonase thiab pectinate lyase.Nws yog tsuas yog siv nyob rau hauv pretreatment scouring txheej txheem rau paj rwb thiab flax fibers.Nws tuaj yeem sib xyaw nrog lwm hom enzymes, uas yog hu ua scouring enzyme.
PS: Nws yog qhov tseeb scouring enzyme!
3. Lipas
Lipase tuaj yeem hydrolyze cov rog hauv glycerol thiab fatty acids.Thiab fatty acids tuaj yeem oxidized ntxiv rau cov suab thaj.
Hauv kev lag luam textile, lipase feem ntau yog siv rau degreasing cov ntaub ntawv textile thiab txhim kho cov khoom.Nws yog tsuas yog siv los kho cov ntaub plaub fibers kom tshem tawm qee cov lipid hauv cov ntaub plaub, uas ua rau cov ntaub plaub fibers muaj kev hloov pauv ntawm lub cev thiab tshuaj thiab txhim kho qhov zoo ntawm cov ntaub plaub.ntaub plaub.
PS: Protease tuaj yeem siv rau hauv cov ntaub plaub.Nws yog tsuas yog siv rau shrink resistant xov rau wool fabrics.
4. Catalase
Catalase yog ib qho enzyme uas catalyzes decomposition ntawm hydrogen peroxide rau hauv oxygen thiab dej.Nws muaj nyob rau hauv peroxide lub cev ntawm cov hlwb.Catalase yog lub cim enzyme ntawm peroxidase, uas yog kwv yees li 40% ntawm tag nrho cov peroxisome enzyme.Catalase muaj nyob hauv txhua cov ntaub so ntswg ntawm txhua tus tsiaj paub.Nws yog tshwj xeeb tshaj yog nyob rau hauv daim siab ntawm high concentrations.
Hauv kev lag luam luam ntawv thiab dyeing, catalase feem ntau hu ua deoxidizing enzyme.Tam sim no, muaj ob hom tseem ceeb hauv kev siv, xws li tsiaj siab catalase thiab cog catalase.Cov tom kawg muaj kev ua tau zoo dua.
5. Amylase
Amylase yog ib lo lus dav dav rau cov enzymes uas hydrolyze starch thiab glycogen.Feem ntau, cov hmoov txhuv nplej siab slurry ntawm cov ntaub yog hydrolyzed los ntawm amylase.Vim tias qhov ua tau zoo thiab qhov tshwj xeeb ntawm amylase, enzyme desizing tus nqi siab thiab desizing ceev ceev.Tsis tas li ntawd nws muaj kuab paug tsawg.Cov ntaub kho mob yogsoftertshaj cov uas kho los ntawm cov txheej txheem acid thiab alkali txheej txheem.Tsis tas li ntawd nws yuav tsis ua puas lub fiber.
Amylase feem ntau hu ua desizing enzyme hauv kev lag luam luam ntawv thiab dyeing.Raws li kev siv kub sib txawv, nws tuaj yeem muab faib ua qhov kub thiab txias desizing enzyme, nruab nrab kub desizing enzyme, kub kub desizing enzyme thiab dav kub desizing enzyme, thiab lwm yam.
6.Laccase/Glucose oxidase
Laccase yog ib hom oxidation-txo enzyme, uas yog cov hloov kho genetic aspergillus niger laccase.Nws tuaj yeem siv rau hauv cov txheej txheem hnav-tiav rau cov ris tsho hnav.Cov ntaub kho mob muaj cov tes tuab zoo nrog lub ntsej muag du thiab ci ntsa iab thiab ci ntsa iab.Glucose oxidase feem ntau yog siv rau hauv cov txheej txheem bleaching rau cov ntaub.Cov ntaub kho mob muaj qhov muag muag thiab plump tes.
PS: Cov khoom sib xyaw ntawm laccase thiab qabzib oxidase tuaj yeem siv los ua cov tshuaj dawb huv hauv cov txheej txheem ua ntej.Tab sis vim yog tus nqi, nws tsis muaj kev nce qib loj.
