Dyeing

Dyeing yog muab faib ua cell dyeing thiab fibrous dyeing

Cell dye
Dyeing yog ib qho tseem ceeb tshaj plaws hauv kev tsim cov iav biocopy.Los ntawm dyeing, cov ntaub so ntswg lom yog raus rau hauv chromosomal, thiab ib feem ntawm cov ntaub so ntswg hlwb yog dyed nrog cov xim sib txawv los yog sib sib zog nqus xim ntawm ntau qhov chaw los tsim cov refractive indexes sib txawv nyob rau hauv thiaj li yuav soj ntsuam.
Feem ntau siv yog Su Mu Jing thiab Yongzang dyeing txoj kev.Su Mu Jing yog alkaline dye thiab dyes qee cov qauv hauv cytoplasm thiab cytoplasm rau hauv xiav.Peb hu qhov xwm txheej ntawm cov phev kab mob no nrog Sumi essence.Yong yog acidic dye, dye cytoplasm thiab inter-cytoplasm rau hauv liab.Peb hu qhov no eosinophility uas yuav dyed los ntawm Yi Hong.Qhov tob dyeing tuaj yeem cuam tshuam alkali thiab eosinophils.Yog tias koj tsis muaj affinity rau ob dyes, nws yog hu ua neutrality.Qee cov ntaub so ntswg tuaj yeem pom cov xim sib txawv ntawm cov xim dye.Thaum dyeing nrog xiav alkaline dyes tolueine, glycosamine polysaccharides nyob rau hauv cov ntaub so ntswg yog dyed ntshav liab.Dye.
Tsis tas li ntawd, txoj kev siv nyiaj dyeing yog siv ntau dua.Thaum cov ntaub so ntswg nkag mus rau hauv cov nyiaj tov, qee cov ntaub so ntswg tuaj yeem ncaj qha rov qab cov nyiaj nitrate, kom cov nyiaj nplej txuas nrog nws, thiab nws yog xim av lossis xim av daj.Qee cov qauv tsis muaj kev kho ncaj qha ntawm cov nyiaj nitrate.

Fibrous staining
Immersed fiber ntau rau hauv cov dej dye dej ntawm qhov kub thiab txias, thiab cov dye txav los ntawm cov dej theem mus rau fiber ntau.Lub sijhawm no, cov xim ntawm cov xim hauv cov dej maj mam txo qis.Tom qab ib lub sij hawm, nws mus txog lub xeev balanced.Qhov txo qis hauv cov dej yog cov xim uas txav mus rau cov fiber ntau.Tshem tawm cov fiber ntau txhua lub sijhawm.Txawm hais tias tus twisted twisted, cov zas xim tseem tshuav nyob rau hauv fiber ntau.Nws tsis tuaj yeem tso cov xim kom deb ntawm fiber ntau.Qhov tshwm sim ntawm cov xim no ua ke hauv cov fiber ntau hu ua dyeing.Yog tias daim txhuam cev rau hauv cov tshuaj zas xim, cov tshuaj zas xim tuaj yeem nkag mus rau sab hauv ntawm daim txhuam cev, tab sis txawm tias lub sijhawm ntev, qhov concentration ntawm cov tshuaj zas xim tsis hloov.Thaum cov sponge yog twisted, cov dyes thiab dej yog squeezed tawm ntawm daim txhuam cev tib lub sij hawm, li ntawd, cov ntaub so ntswg yog hais tias yog daim txhuam cev.Nws tsis yog xim av.

Lub hauv paus txheej txheem ntawm dyeing yog raws li kev xav ntawm niaj hnub dyeing txoj kev xav.Yog vim li cas vim li cas dyes tuaj yeem dyed rau ntawm cov ntaub fiber ntau muaj qee qhov ceev ceev vim tias muaj ntau qhov sib nqus ntawm cov xim molecules thiab fiber ntau molecules.Lub hauv paus ntsiab lus dyeing thiab dyeing txheej txheem yog txawv heev vim cov yam ntxwv ntawm dyes thiab fibers.Nws tsis tuaj yeem hais dav dav.Txawm li cas los xij, raws li nws cov txheej txheem dyeing muaj kev txhawj xeeb, nws tuaj yeem muab faib ua peb theem pib.
1. Tom qab cov fiber ntau muab tso rau hauv cov xim da dej, cov dye kis mus rau saum npoo ntawm cov fiber ntau ua ntej, thiab tom qab ntawd maj mam hloov ntawm cov tshuaj mus rau qhov chaw fiber ntau.Cov txheej txheem no hu ua adsorption.Nyob rau tib lub sijhawm, cov xim xim ntawm cov fiber ntau maj mam nce, thaum cov xim xim hauv cov tshuaj maj mam txo qis, thiab tom qab lub sijhawm, nws nce mus txog qhov sib npaug.Cov txheej txheem adsorption thim rov qab yog los daws qhov nqus, thiab adsorption thiab kev sib haum xeeb thaum lub sij hawm dyeing sab sauv muaj nyob rau tib lub sijhawm.
2. Cov zas xim uas diffuses rau saum npoo ntawm cov fibers yog kis mus rau hauv cov fiber ntau kom txog thaum cov xim xim ntawm txhua feem ntawm cov fiber ntau zoo ib yam.Vim yog qhov dye concentration ntawm cov dye uas yog adsorbed rau ntawm qhov chaw ntawm fiber ntau, qhov dye concentration yog ntau dua li cov fiber ntau.Nyob rau lub sijhawm no, qhov diffusion ntawm cov dye rhuav tshem qhov pib adsorption tshuav, thiab cov dyes hauv cov tshuaj yuav txuas ntxiv adsorb rau fiber ntau, thiab cov adsorption thiab reconciliation yuav nce mus txog qhov sib npaug dua.
3. Kev sib koom ua ke yog cov txheej txheem ntawm kev khi dyes thiab fiber ntau.Nrog cov dyes sib txawv thiab fibers, kev sib xyaw ua ke kuj txawv.
Cov theem saum toj no feem ntau muaj nyob rau tib lub sijhawm thaum lub sijhawm dyeing, thiab tsis tuaj yeem sib cais tag nrho.Nws tsuas yog ib lub sijhawm ntawm dyeing.
