Nws paub zoo tias spandex fiber ntau tuaj yeem dyed nrog disperse dyes thiab acid dyes, tab sis ceev ceev ntawm ob dyes no tsis zoo.Feem ntau cov kev sim tau ua pov thawj tias cov xim reactive rau nylon thiab disperse cationic dyes yeej tsis tawm xim ntawm spandex.Qhov no puas qhia tau tias ob lub dyes tsis haum rau spandex dyeing?Qhov tseeb, nws tsis yog li ntawd.Nrog rau cov catalysis ntawm cov pab pawg tsim nyog, reactive dyes rau nylon tuaj yeem siv rau dyeing ntawm spandex, thiab nws ceev thiab qhov tob zoo dua.Hauv qab no yog ib qho kev soj ntsuam ntxaws.
1. Muaj ob peb ntshiab spandex fabrics nyob rau hauv kev ua lag luam, yog li dyeing ntawm spandex kuj tsis paub rau peb.Ntshiab spandex fabrics tuaj yeem siv ua ke nrog cov ntaub tsis muaj elastic lossis inelastic fabrics, uas tuaj yeem ua rau kom elasticity thiab resilience ntawm cov ntaub.Thiab thaum lub elastic ntaub yog stretched los yog nias, yog hais tias cov xim ntawm spandex fiber tsis zoo ib yam nrog cov filament, yuav muaj teeb meem ntawm cov xim to ntawm spandex, uas yuav tsum tau dyeing ntawm spandex.
2. Rau lub teeb xim dyeing ntawm spandex, acidic dye los yog disperse dye yuav siv tau nyob rau hauv acidic da dej tej yam kev mob.Nyob rau hauv cov xwm txheej ntawm kev siv tib dye dyes, disperse dyes muaj ceev ceev zoo dua acidic dyes ntawm spandex, tab sis txawv disperse dyes muaj sib txawv ceev ntawm spandex.Feem ntau, yog tias cov tshuaj zas xim tsawg dua 0.5%, disperse dyes tuaj yeem txais yuav.
3. Spandexfiber yog siab elastic fiber ntau.Xav tias dyeing spandex ntev ntev nyob rau hauv qhov kub thiab txias yuav ua rau elastic tsis ua hauj lwm, feem ntau yog dyed hauv qab 100 ℃.Dab tsi ntxiv, spandex tsis resistant rau alkali, thiab disperse dyes thiab acid dyes yog haum rau dyeing nyob rau hauv acidic tej yam kev mob.Feem ntau, dyeing ntawm spandex yog ua nyob rau hauv acidic tej yam kev mob nrog ib tug pH ntawm txog 5.
4. Ntau hom dyes, nrog rau cov auxiliaries tsim nyog raws li nruab nrab, tuaj yeem siv los zas cov spandex fiber ntau.Hom kev pabcuam hauv kev ua lag luam no yog hu ua spandex coloring agent lossis spandex colorant, uas yog tsuas yog siv rau kev tuag ntawm reactive dyes rau nylon thiab acid dyes ntawm spandex, uas feem ntau khav amphoteric ion zog.Lub hauv paus ntsiab lus ntawm kev txiav txim yog ntxhib raws li nram no: Nyob rau hauv acidic tej yam kev mob, lub amide daim ntawv cog lus thiab lwm yam pab pawg neeg nyob rau hauv lub spandex ionize, nrog ib tug zoo nqi, uas tej zaum yuav muaj ib tug tshuaj tiv thaiv nrog spandex colorant.Tom qab ntawd kho tus neeg sawv cev yog tsau rau hauv spandex vim tias cov xim spandex muaj cov amino zoo ions, cov xim dye thiab spandex tuaj yeem ua ke.
5. Cov kev cai dav dav ntawm kev ceev ceev tom qab dyeing ntawm spandex: Ntxuav > hws stain (acid) > soaking, thiab ceev ceev ntawm lub web rubbing yog zoo dua li ntawm qhuav txhuam.
