Yuav ua li cas txhim kho qhov ceev ntawm kev zas xim ntawm cov ntaub luam tawm thiab cov ntaub zas xim kom tau raws li qhov kev thov ntawm kev lag luam textile uas nce zuj zus tau dhau los ua ib qho kev tshawb fawb hauv kev lag luam luam ntawv thiab zas xim. Tshwj xeeb, qhov ceev ntawm cov xim reactive rau cov ntaub xim dawb, qhov ceev ntawm kev sib txhuam ntub ntawm cov ntaub tsaus thiab tuab; qhov poob qis ntawm kev kho mob ntub los ntawm kev hloov pauv thermal ntawm cov xim disperse tom qab zas xim; thiab qhov ceev ntawm chlorine siab, qhov ceev ntawm hws-lub teeb thiab lwm yam.

Muaj ntau yam uas cuam tshuam rau qhov xim ruaj khov, thiab muaj ntau txoj hauv kev los txhim kho qhov xim ruaj khov. Tau ntau xyoo ntawm kev xyaum ua haujlwm ntau lawm, cov kws tshaj lij luam ntawv thiab zas xim tau tshawb nrhiav kev xaiv cov zas xim thiab cov tshuaj ntxiv uas tsim nyog, kev txhim kho cov txheej txheem zas xim thiab ua tiav, thiab kev txhawb nqa kev tswj hwm cov txheej txheem. Qee txoj kev thiab kev ntsuas tau raug siv los ua kom nce thiab txhim kho qhov xim ruaj khov mus rau qee qhov, uas feem ntau ua tau raws li qhov xav tau ntawm kev ua lag luam.

Lub teeb nrawm ntawm cov xim reactive dyes lub teeb xim ntaub

Raws li peb txhua tus paub, cov xim pleev xim rau ntawm cov paj rwb raug tawm tsam los ntawm cov duab ultraviolet hauv qab lub hnub ci, thiab cov chromophores lossis auxochromes hauv cov qauv xim yuav raug puas tsuaj rau ntau qib, ua rau muaj kev hloov xim lossis xim kaj, uas yog teeb meem ntawm lub teeb.

Cov qauv hauv tebchaws ntawm kuv lub tebchaws twb tau teev tseg qhov ceev ntawm cov xim reactive. Piv txwv li, GB/T411-93 paj rwb luam ntawv thiab zas xim ntaub txheem hais tias qhov ceev ntawm cov xim reactive yog 4-5, thiab qhov ceev ntawm cov ntaub luam tawm yog 4; GB/T5326 Combed polyester-paj rwb sib xyaw luam ntawv thiab zas xim ntaub txheem thiab FZ/T14007-1998 paj rwb-polyester sib xyaw luam ntawv thiab zas xim ntaub txheem ob qho tib si hais tias qhov ceev ntawm cov ntaub dispersed/reactive dyed yog theem 4, thiab cov ntaub luam tawm kuj yog theem 4. Nws nyuaj rau cov xim reactive zas xim cov ntaub luam tawm xim sib dua kom ua tau raws li tus qauv no.

Kev sib raug zoo ntawm cov qauv matrix dye thiab lub teeb fastness

Qhov ceev ntawm cov xim reactive feem ntau yog cuam tshuam nrog cov qauv matrix ntawm cov xim. 70-75% ntawm cov qauv matrix ntawm cov xim reactive yog hom azo, thiab cov seem yog hom anthraquinone, hom phthalocyanine thiab hom A. Hom azo muaj qhov ceev tsis zoo, thiab hom anthraquinone, hom phthalocyanine, thiab ntsia hlau muaj qhov ceev zoo dua. Cov qauv molecular ntawm cov xim daj reactive yog hom azo. Cov xim niam txiv yog pyrazolone thiab naphthalene trisulfonic acid rau qhov ceev zoo tshaj plaws. Cov xim xiav spectrum reactive yog anthraquinone, phthalocyanine, thiab cov qauv niam txiv. Qhov ceev zoo heev, thiab cov qauv molecular ntawm cov xim liab spectrum reactive yog hom azo.

Qhov ceev ntawm lub teeb feem ntau qis, tshwj xeeb tshaj yog rau cov xim kaj.

Kev sib raug zoo ntawm dyeing density thiab lub teeb fastness
Qhov ceev ntawm cov qauv dyed yuav txawv nrog rau qhov kev hloov pauv ntawm qhov concentration ntawm dyeing. Rau cov qauv dyed nrog tib lub zas xim rau ntawm tib lub fiber, nws qhov ceev ntawm lub teeb nce nrog rau qhov nce ntawm qhov concentration ntawm dyeing, feem ntau vim tias cov zas xim yog los ntawm kev hloov pauv ntawm qhov loj me ntawm cov khoom sib sau ua ke ntawm cov fiber.

Qhov loj dua ntawm cov khoom sib sau ua ke, qhov me dua thaj chaw ib chav ntawm qhov hnyav ntawm cov xim pleev xim uas raug rau huab cua-dej noo, thiab qhov siab dua qhov ceev ntawm lub teeb.
Qhov kev nce ntxiv ntawm cov xim zas yuav ua rau muaj qhov sib piv ntawm cov khoom loj loj ntawm cov fiber, thiab qhov ceev ntawm lub teeb yuav nce ntxiv raws li. Qhov kev sib piv ntawm cov xim zas ntawm cov ntaub xim dawb yog qis, thiab qhov sib piv ntawm cov xim zas ntawm cov fiber yog qis. Feem ntau ntawm cov xim zas yog nyob rau hauv ib lub xeev molecule, uas yog, qib ntawm kev lwj ntawm cov xim zas ntawm cov fiber yog siab heev. Txhua lub molecule muaj tib qho feem pua ​​ntawm kev raug lub teeb thiab huab cua. , Qhov cuam tshuam ntawm cov dej noo, qhov ceev ntawm lub teeb kuj txo qis raws li.

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

Cov kev ntsuas los txhim kho qhov ceev ntawm lub teeb

1. Kev xaiv cov xim pleev xim cuam tshuam rau cov ntaub xim dawb
Qhov tseem ceeb tshaj plaws hauv kev ua kom lub teeb ci ntsa iab yog cov xim nws tus kheej, yog li kev xaiv cov xim yog qhov tseem ceeb tshaj plaws.
Thaum xaiv cov xim rau kev sib phim xim, xyuas kom meej tias qib kev sib zog ntawm txhua cov xim xaiv yog sib npaug, tsuav yog ib qho ntawm cov khoom, tshwj xeeb tshaj yog cov khoom uas muaj tsawg tshaj plaws, tsis tuaj yeem ncav cuag qhov kev sib zog ntawm cov khoom siv xim sib zog. Cov kev cai ntawm cov khoom siv xim kawg yuav tsis ua tau raws li tus qauv kev sib zog.

2. Lwm yam kev ntsuas
Cov nyhuv ntawm cov xim ntab.
Kev zas xim thiab xab npum tsis yog qhov ua tiav, thiab cov xim tsis ruaj khov thiab cov xim hydrolyzed uas tseem tshuav ntawm daim ntaub kuj tseem yuav cuam tshuam rau qhov ceev ntawm cov khoom siv dyed, thiab lawv qhov ceev ntawm lub teeb qis dua li ntawm cov xim reactive ruaj khov.
Qhov ua kom xab npum ntau ntxiv, qhov zoo dua qhov ci ntsa iab.

Kev cuam tshuam ntawm cov tshuaj kho thiab cov tshuaj softener.
Cov tshuaj cationic low-molecular-weight los yog polyamine-condensed resin type fixing agent thiab cationic softener yog siv rau hauv kev ua kom tiav cov ntaub, uas yuav txo qhov light fastness ntawm cov khoom dyed.
Yog li ntawd, thaum xaiv cov neeg sawv cev kho thiab cov khoom ua kom mos, yuav tsum tau them sai sai rau lawv cov kev cuam tshuam rau lub teeb ci ntawm cov khoom dyed.

Kev cuam tshuam ntawm UV absorbers.
Cov tshuaj nqus ultraviolet feem ntau siv rau hauv cov ntaub xim sib dua los txhim kho lub teeb ci, tab sis lawv yuav tsum tau siv ntau heev kom muaj qee qhov cuam tshuam, uas tsis tsuas yog ua rau tus nqi nce ntxiv, tab sis kuj ua rau daj thiab puas tsuaj rau cov ntaub, yog li nws zoo tshaj plaws tsis txhob siv txoj kev no.
