Raws li cov koom haum tseem ceeb hauv kev kho mob ua ntej dyeing thiab xov, textile pretreatment agents yog tus cwj pwm los ntawm kev sib sib zog nqus hloov mus rau fiber ntau, kev ua tiav ntawm cov hom phiaj ntawm cov txheej txheem, thiab qhov sib npaug ntawm kev tiv thaiv ib puag ncig thiab kev ua haujlwm zoo. Cov yam ntxwv no tsis tsuas yog txiav txim siab qhov kev ruaj ntseg zoo ntawm cov txheej txheem pretreatment tab sis kuj tseem cuam tshuam cov kev xav tau ntawm kev tshawb fawb tshuaj textile thiab kev loj hlob los ntawm "kev tshem tawm impurity ntau" mus rau "kev ua kom zoo dua qub."
Firstly, lawv cov dej num yog heev tsom thiab complex. Cov fibers sib txawv muaj qhov sib txawv ntawm cov impurity: paj rwb fibers muaj cov hmoov txhuv nplej siab, pectin, thiab waxes, thaum hluavtaws fibers xws li polyester yog coated nrog spinning roj thiab oligomers. Blended fabrics yuav tsum hais txog kev sib koom ua ke ntawm ntau yam khoom. Pretreatment agents, los ntawm kev tsim qauv molecular thiab cov khoom sib xyaw ua ke, ua tiav cov kev xaiv ntawm cov impurities tshwj xeeb-piv txwv li, amylase kev npaj ua kom tiav cov hmoov txhuv nplej siab glycosidic daim ntawv cog lus, thiab surfactant compounding systems ib txhij emulsify roj thiab disperse colloidal impurities, ua tiav ntau cov txheej txheem impurities- kev koom ua ke.
Qhov thib ob, cov txheej txheem ua haujlwm qhia txog kev ua siab mos siab muag thiab kev tswj hwm. Ib txwm ua ua ntej tso siab rau muaj zog alkalis thiab oxidants, uas tuaj yeem ua rau muaj zog fiber ntau thiab ua rau muaj kev puas tsuaj ntau dhau. Cov tshuaj ua ntej niaj hnub no, siv bio-enzyme catalysis, tsis muaj zog acidic tsis muaj zog, thiab qis- cov tshuaj tiv thaiv kab mob, tuaj yeem ua tiav kev tshem tawm impurity zoo nyob rau hauv ib txwm lossis nruab nrab- qhov kub thiab txias, txo qhov cuam tshuam ntawm cov khoom siv fiber ntau. Qee cov khoom lag luam suav nrog pH- teb lossis qhov kub thiab txias- cov pab pawg rhiab, dynamically kho cov kev ua ub no raws li cov txheej txheem tsis ua kom tsis txhob muaj ntaub embrittlement los yog xim txawv teeb meem tshwm sim los ntawm ntau lub zos cov tshuaj tiv thaiv.
Thirdly, lawv pom zoo ib puag ncig tus phooj ywg thiab kev siv peev txheej. Tau ntsib txoj kev lag luam "dual carbon" cov hom phiaj thiab kev txhim kho dej kom zoo, cov neeg ua haujlwm ua ntej hais txog kev siv bio-raws li cov ntaub ntawv (xws li cov nroj tsuag- tau txais surfactants), biodegradable structural designs (xws li yooj yim hydrolyzable ester bonds), thiab qis -foaming, yooj yim tsim cov dej pov tseg,- rinsing dej siv. Nyob rau tib lub sijhawm, los ntawm kev txhim kho qhov ua tau zoo ntawm ib chav tsev ntau npaum li cas, lawv txo qis tag nrho cov khoom siv tshuaj lom neeg, ua tiav cov peev txheej - qauv hnyav ntawm "tsawg npaum li cas, cov zis siab."
Thib plaub, lawv tau mus tom ntej - saib thiab hloov mus rau kev tsim khoom ntse. Kev ua kom zoo ntawm cov neeg ua haujlwm kho mob ua ntej raws li cov khoom siv rheological, kev ruaj ntseg dispersion, thiab kev sib raug zoo ua rau lawv txuas nrog kev saib xyuas online, txhawb nqa tiag tiag - lub sijhawm tswj hwm kev tswj hwm thiab cov ntawv thov tsis tu ncua hauv kev tsim khoom. Qhov no txo qis tib neeg kev ua yuam kev thiab muab qhov tseem ceeb lav rau kev tswj cov txheej txheem meej hauv cov chaw tsim khoom digital.
Nyob rau hauv cov ntsiab lus, textile pretreatment agents, nrog lawv cov yam ntxwv tseem ceeb ntawm lub hom phiaj meej, me me thiab tswj cov khoom, ntsuab thiab qis -cov yam ntxwv ntawm carbon, thiab ntse adaptability, tsis tsuas yog solidify lub hauv paus ntawm dyeing thiab xov zoo tab sis kuj yog ib qho tseem ceeb technologies txhawb kev loj hlob ntawm kev lag luam textile.
