Yuav ua li cas txhawm rau txhim kho dyeing ceev ntawm cov ntawv luam tawm thiab dyed fabrics kom tau raws li qhov kev xav tau ntawm textile kev lag luam tau dhau los ua ib lub ntsiab lus tshawb fawb hauv kev lag luam luam ntawv thiab dyeing.Hauv particular, lub teeb ceev ceev ntawm reactive dyes rau lub teeb-xim fabrics, ntub rubbing ceev ceev ntawm maub thiab ntom fabrics;qhov poob ntawm kev kho ntub dej sai sai tshwm sim los ntawm thermal migration ntawm disperse dyes tom qab dyeing;thiab siab chlorine ceev, hws-lub teeb ceev ceev ceev thiab lwm yam.

Muaj ntau yam uas cuam tshuam rau xim ceev, thiab muaj ntau txoj hauv kev los txhim kho xim ceev.Los ntawm xyoo ntawm kev xyaum ntau lawm, luam ntawv thiab dyeing practitioners tau tshawb fawb nyob rau hauv kev xaiv ntawm haum dyeing thiab tshuaj additives, txhim kho dyeing thiab tiav cov txheej txheem, thiab ntxiv dag zog rau cov txheej txheem tswj.Qee txoj hauv kev thiab kev ntsuas tau raug coj los ua kom nce thiab txhim kho cov xim nrawm rau qee qhov, uas ua tau raws li qhov xav tau ntawm kev lag luam.

Lub teeb ceev ceev ntawm reactive dyes lub teeb-xim ntaub

Raws li peb txhua tus paub, reactive dyes dyed ntawm paj rwb fibers raug tawm tsam los ntawm ultraviolet rays nyob rau hauv lub hnub ci, thiab cov chromophores los yog auxochromes nyob rau hauv cov qauv dye yuav puas mus rau txawv degrees, ua rau cov xim hloov los yog lub teeb xim, uas yog teeb meem ceev ceev.

kuv lub teb chaws cov qauv hauv teb chaws twb tau teev tseg lub teeb nrawm ntawm cov xim reactive.Piv txwv li, GB / T411-93 paj rwb luam ntawv thiab dyeing ntaub tus qauv qhia tias lub teeb ceev ntawm reactive dyes yog 4-5, thiab lub teeb ceev ntawm cov ntaub ntawv luam tawm yog 4;GB / T5326 Combed polyester-paj rwb blended printing thiab dyeing ntaub qauv thiab FZ / T14007-1998 paj rwb-polyester blended luam ntawv thiab dyeing ntaub txheem ob leeg hais tias lub teeb ceev ntawm dispersed / reactive dyed ntaub yog qib 4, thiab cov ntaub ntawv luam tawm kuj yog qib. 4. Nws yog ib qho nyuaj rau reactive dyes rau dye lub teeb-xim luam ntawv fabrics kom tau raws li tus qauv no.

Kev sib raug zoo ntawm dye matrix qauv thiab lub teeb ceev ceev

Lub teeb ceev ntawm reactive dyes feem ntau cuam tshuam nrog cov qauv matrix ntawm cov xim.70-75% ntawm cov qauv matrix ntawm reactive dyes yog azo hom, thiab tus so yog anthraquinone hom, phthalocyanine hom thiab A hom.Hom azo muaj lub teeb tsis zoo, thiab hom anthraquinone, phthalocyanine hom, thiab ntsia thawv muaj lub teeb nrawm dua.Cov qauv molecular ntawm daj reactive dyes yog hom azo.Cov niam txiv xim lub cev yog pyrazolone thiab naphthalene trisulfonic acid rau lub teeb nrawm tshaj plaws.Cov xim xiav spectrum reactive dyes yog anthraquinone, phthalocyanine, thiab niam txiv qauv.Lub teeb ceev ceev yog qhov zoo heev, thiab cov qauv molecular ntawm cov xim liab spectrum reactive dye yog hom azo.

Lub teeb ceev ceev yog feem ntau qis, tshwj xeeb tshaj yog rau cov xim lub teeb.

Kev sib raug zoo ntawm dyeing ceev thiab lub teeb ceev ceev
Lub teeb nrawm ntawm cov qauv dyed yuav txawv nrog qhov kev hloov ntawm dyeing concentration.Rau cov qauv dyed nrog tib dye rau tib fiber ntau, nws lub teeb ceev ceev nce nrog qhov nce ntawm dyeing concentration, feem ntau vim tias cov dyeing yog nyob rau hauv qhov tshwm sim los ntawm kev hloov pauv ntawm qhov loj me ntawm cov khoom sib xyaw ntawm cov fiber ntau.

Qhov loj dua cov khoom sib sau ua ke, qhov me me ntawm thaj tsam ntawm ib chav tsev qhov hnyav ntawm cov xim raug rau huab cua-nqus dej, thiab lub teeb nrawm dua.
Qhov nce hauv dyeing concentration yuav nce qhov feem ntawm cov aggregates loj ntawm cov fiber ntau, thiab lub teeb nrawm yuav nce raws li.Lub dyeing concentration ntawm lub teeb-xim ntaub yog tsawg, thiab qhov feem ntawm dye aggregates ntawm fiber yog tsawg.Feem ntau ntawm cov dyes yog nyob rau hauv ib lub xeev molecule, uas yog, lub degree ntawm decomposition ntawm cov xim ntawm fiber ntau yog heev.Txhua lub molecule muaj qhov tshwm sim zoo ib yam ntawm kev raug rau lub teeb thiab huab cua., Cov nyhuv ntawm noo noo, lub teeb ceev ceev kuj txo raws li.

ISO / 105B02-1994 tus qauv lub teeb nrawm tau muab faib ua 1-8 qib kev ntsuas tus qauv, kuv lub teb chaws tus qauv kuj muab faib ua 1-8 qib kev ntsuas tus qauv, AATCC16-1998 lossis AATCC20AFU tus qauv ntsuas lub teeb nrawm tau muab faib ua 1-5 qib kev ntsuas tus qauv .

Kev ntsuas los txhim kho lub teeb nrawm

1. Kev xaiv cov xim muaj feem cuam tshuam rau cov ntaub xim xim
Qhov tseem ceeb tshaj plaws nyob rau hauv lub teeb ceev ceev yog cov xim nws tus kheej, yog li kev xaiv cov xim yog qhov tseem ceeb tshaj plaws.
Thaum xaiv cov dyes rau cov xim sib xws, xyuas kom meej tias lub teeb nrawm ntawm txhua qhov xim xim xaiv yog sib npaug, tsuav yog ib qho ntawm cov khoom siv, tshwj xeeb tshaj yog cov khoom siv nrog tsawg kawg nkaus, tsis tuaj yeem ncav cuag lub teeb nrawm ntawm lub teeb xim. dyed khoom Cov kev xav tau ntawm cov khoom siv dyed zaum kawg yuav tsis ua raws li tus qauv ntawm lub teeb nrawm.

2. Lwm yam kev ntsuas
Cov nyhuv ntawm floating dyes.
Kev dyeing thiab soaping tsis yog tag nrho, thiab cov dyes unfixed thiab hydrolyzed dyes nyob rau hauv daim ntaub yuav cuam tshuam lub teeb ceev ceev ntawm cov khoom dyed, thiab lawv lub teeb ceev ceev yog ho qis dua li cov reactive dyes.
Qhov ua kom zoo dua soaping, qhov zoo dua lub teeb nrawm.

Kev cuam tshuam ntawm kev kho tus neeg sawv cev thiab softener.
Cationic low-molecular-weight los yog polyamine-condensed resin hom kho tus neeg saib xyuas thiab cationic softener yog siv nyob rau hauv ntaub xov, uas yuav txo tau lub teeb ceev ntawm dyed khoom.
Yog li ntawd, thaum xaiv kho cov neeg ua hauj lwm thiab softeners, yuav tsum tau them nyiaj mloog mus rau lawv lub zog ntawm lub teeb ceev ceev ntawm dyed khoom.

Kev cuam tshuam ntawm UV absorbers.
Ultraviolet absorbers feem ntau yog siv rau hauv cov xim xim dyed fabrics los txhim kho lub teeb nrawm, tab sis lawv yuav tsum tau siv ntau ntau kom muaj qee qhov cuam tshuam, uas tsis tsuas yog nce tus nqi, tab sis kuj ua rau yellowing thiab muaj zog puas tsuaj rau cov ntaub, yog li ntawd. nws yog qhov zoo tshaj kom tsis txhob siv txoj kev no.
