Yuav ua li cas los txhim kho cov xim ceev ntawm cov ntaub, ntaub xim ceev yog hais txog dyeing ceev ntawm textiles, hu ua xim ceev ceev, yog dyed los yog luam ntaub nyob rau hauv kev siv los yog txheej txheem, raug rau lwm yam, extrusion, txhuam, ntxuav, los nag. , raug, lub teeb, seawater immersion, qaub ncaug immersion, dej stains, hws stains nyob rau hauv qhov kev txiav txim ntawm lub degree ntawm fading, yog ib qho tseem ceeb qhia ntawm ntaub.
Cov xim ceev ceev yog qhov zoo, cov ntaub ntawv tsis yooj yim rau ploj thaum lub sijhawm ua haujlwm tom qab lossis siv, thiab xim ceev ceev tsis zoo, yuav muaj fading, discoloration, lossis staining, ua rau muaj teeb meem ntau. Cov kev ntsuas los txhim kho cov xim ceev ntawm lub teeb, tsim nyog xaiv cov dyes, hauv kev txhim kho qhov ceev ntawm lub hnub ci, kev xaiv dyes yog qhov tseem ceeb.
Tag nrho cov dyes yuav tawm floating dye nyob rau hauv fiber ntau tom qab luam ntawv thiab dyeing, qhov ntau npaum li cas ntawm cov dyeing, qhov ntau floating dye yog khi kom muaj ib tug txwv tus nqi rau cov adsorption ntawm txhua dye, uas yog, cov xim saturation tus nqi, lub general. tus nqi ntawm cov xim tsis tuaj yeem tshaj li 10% ntawm tus nqi saturation. Thaum cov xim ntau dhau ntawm tus nqi saturation, cov xim ntau dhau tsis tuaj yeem dyed thiab kho, thiab tsuas yog tuaj yeem sib sau rau ntawm cov ntaub, uas cuam tshuam rau kev sib txhuam xim ceev ntawm cov ntaub.
Cov dyed tsis zoo, yooj yim poob ntawm cov fiber ntau, thiab cov xab npum ceev ceev tsis zoo, kev ntxuav tsis huv tom qab dyeing, thiab cov xim ntab yog qhov seem, uas tseem yuav ua rau txo qis ntawm xab npum ceev. Qhov kub, pH tus nqi thiab nplawm ntawm cov kua xab npum muaj kev cuam tshuam rau cov xab npum ceev, thiab cov xim zas xim feem ntau muaj kev cuam tshuam me me rau cov xab npum ceev ceev thaum dyeing, tab sis cov dye concentration yog siab, thiab kev sib xyaw ntawm cov xim thiab fiber ntau. yog super-saturated. Cov dyeing yog ib qho yooj yim kom poob rau hauv lub zog sab nraud, uas tseem cuam tshuam rau cov xab npum ceev ceev.
Peb thawj xim nrog lub hnub ceev ceev yuav tsum tau xaiv. Anthraquinone, phthalocyanine thiab lwm yam dyes nrog lub teeb xim zoo nrawm yuav tsum raug xaiv rau xiav chromatography. Lub hnub tsis zoo yuav cuam tshuam rau lub hnub nrawm ntawm tag nrho cov xim sib xyaw. Cov ntsiab lus me me ntawm cov dyes hauv cov xim sib xyaw tuaj yeem xaiv cov dyes nrog qib siab ceev, thiaj li ua kom cov xim zuag qhia tag nrho ntawm cov ntaub rau lub hnub.
Tag nrho cov xab npum thiab ntxuav, txo qhov nyiaj ntawm hydrolyzed dyes thiab ntab xim los txhim kho lub hnub ceev ntawm cov ntaub, kev xaiv cov xim kho cov neeg ua haujlwm, muaj peb hom xim kho cov neeg ua haujlwm, cationic, tsis-nto active quaternary ammonium ntsev hom , hom tshuaj tiv thaiv. Ntawm lawv, cationic fixing agent thiab dye tsim xim pas dej ntawm cov fiber ntau, txawm hais tias kev ntxuav ceev ceev yog qhov zoo heev, tab sis feem ntau txo qis lub hnub ceev ceev ntawm cov dye, lub teeb xim fabrics yuav tsum tau siv tsawg li ntau tau los yog tsis.
Muaj ntau yam cuam tshuam rau cov xim ceev ntawm cov khoom dyed, tab sis nws tsuas yog nyob ntawm cov qauv tshuaj ntawm cov xim, lub cev lub cev ntawm cov xim ntawm cov fiber ntau, qhov degree ntawm dispersion ntawm cov dye, kev sib xyaw nrog fiber ntau, cov concentration. ntawm cov dyeing, txoj kev dyeing thiab cov txheej txheem tej yam kev mob kuj muaj kev cuam tshuam zoo rau dyeing ceev ceev. Qhov xwm ntawm fiber ntau kuj muaj feem xyuam rau dyeing ceev, thiab tib dye feem ntau muaj qhov sib txawv ceev ntawm cov fibers sib txawv.
