Nyob rau hauv textile dyeing thiab xov teb, dyeing auxiliaries tau ntev dhau los ntawm lawv lub luag haujlwm ib txwm ua "cov ntaub ntawv pabcuam," dhau los ua cov ntsiab lus tseem ceeb txiav txim siab dyeing zoo, ntau lawm efficiency, thiab kev txhim kho kom ruaj khov. Lawv cov txiaj ntsig tsis yog nyob rau hauv kev tswj hwm ntawm cov txheej txheem dyeing nkaus xwb tab sis kuj tseem cuam tshuam rau kev siv cov peev txheej, kev cuam tshuam ib puag ncig, thiab kev sib tw ntawm cov khoom lag luam, rov tsim cov txiaj ntsig ntawm cov txiaj ntsig ntawm dyeing thiab xov kev lag luam.
Los ntawm kev pom zoo, dyeing auxiliaries yog qhov tseem ceeb rau kev ua kom cov xim sib xws thiab xim ceev. Cov fibers ntuj, vim lawv cov qauv saum npoo thiab cov tshuaj lom neeg muaj pes tsawg leeg, ua rau cov xim tsis sib xws adsorption, ua rau xim pob thiab streaks. Leveling agents dynamically sib npaug ntawm affinity ntawm fibers thiab dye cawv, coj cov dye gradient upwards thiab tswj cov xim sib txawv ntawm fabrics mus rau ib tug ntau yam imperceptible rau qhov muag liab qab. Nyob rau hauv hluavtaws fiber ntau dyeing, dispersants tuav ruaj khov ncua kev kawm ntawv ntawm dye hais, tiv thaiv xim me ntsis tshwm sim los ntawm aggregation thiab kom ntseeg tau tias uniform xim tawm los thaum dyeing polyester nrog disperse dyes. Txhim kho cov neeg ua haujlwm tsim covalent lossis ionic bonds nrog cov xim molecules lossis fibers, txhim kho qhov nrawm nrawm ntawm cov xim reactive dyes mus rau qib 4 lossis siab dua, ua tau raws li qhov ntev -lub sij hawm durability ntawm siab-kawg apparel thiab industrial textiles. Cov teebmeem no ncaj qha txhim kho cov khoom lag luam lees paub thiab cov npe hwm.
Nyob rau hauv cov nqe lus ntawm ntau lawm efficiency, dyeing auxiliaries yog tus tsav tsheb tseem ceeb ntawm kev txo nqi thiab kev txhim kho efficiency. Accelerators luv dyeing cua sov lub sij hawm los ntawm kev txo dye dissolution activation zog los yog tsis muaj zog deg nqi repulsion, txo lub siab - kub, siab - siab dyeing voj voog rau polyester los ntawm cov tsoos 60 feeb mus rau tsawg tshaj li 40 feeb, ua rau ib hnub muaj peev xwm ntawm kwv yees li 30%. Daim ntawv thov ntawm qis -kub dyeing auxiliaries tuaj yeem txo qhov kub ntawm dyeing ntawm paj rwb fibers nrog reactive dyes los ntawm 95℃mus rau 80 degree, txo chav zog noj ntau tshaj 25%. Defoamers suppress ua npuas dej ntau dhau hauv cov khoom siv dav hlau dyeing, txo cov dye cawv pov tseg thiab downtime rau kev tu, txhim kho tag nrho cov cuab yeej siv tau zoo (OEE) los ntawm 15% -20%. Cov kev txhim kho no tsis yog tsuas yog txo cov nqi ua haujlwm ntawm cov khoom lag luam xwb tab sis kuj txo qis kev muaj peev xwm hauv cov nroj tsuag dyeing.
Los ntawm txoj kev loj hlob ruaj khov, tus nqi ntawm dyeing auxiliaries hloov mus rau ib puag ncig tus phooj ywg thiab kev txuag nyiaj txiag. Phosphate-dawb chelating agents hloov cov tshuaj phosphates, txo qhov kev pheej hmoo ntawm eutrophication ntawm qhov chaw; bio-raws li cov neeg ua haujlwm theem, ua los ntawm biodegradable polysaccharides, tau yooj yim decomposed los ntawm cov kab mob tom qab siv, txo COD load hauv dyeing thiab tiav cov dej khib nyiab; qis- txiv qaub- piv dyeing auxiliaries, ua ke nrog me me - txiv qaub- cov khoom siv sib piv, txo cov dej haus los ntawm cov tsoos 1:20 mus rau 1:8, txuag tshaj 60% ntawm cov dej ib tuj ntawm cov ntaub. Cov kev tsim kho tshiab no ua rau nws yooj yim dua rau dyeing thiab ua tiav cov tuam txhab kom ua tau raws li cov kev cai ib puag ncig thiab hom ESG cov cai, nthuav dav kev lag luam nkag mus rau thaj tsam.
Tam sim no, cov neeg siv khoom xav tau rau cov xim tus kheej thiab cov khoom lag luam ntsuab tau nce ntxiv. Dyeing auxiliaries, los ntawm kev tswj cov xim zoo, txo tus nqi tsis xws luag, thiab kev xa khoom luv luv, tau dhau los ua qhov tseem ceeb txuas txuas kev lag luam xav tau thiab kev tsim khoom kawg. Kev sib cuam tshuam ntawm lawv cov ntau-seem tus nqi tsis yog tsuas yog tsav cov dyeing thiab ua tiav kev lag luam mus rau siab- zoo, qis- kev hloov pauv kev noj mov tab sis kuj tsim kom muaj txiaj ntsig zoo tshaj plaws uas nyuaj rau kev rov ua dua tshiab hauv ntiaj teb textile supply chain kev sib tw.
