Webbing dyeing hauv paus: cov txheej txheem yooj yim ntawm dyeing Raws li niaj hnub dyeing txoj kev xav, yog vim li cas dyes tuaj yeem dye fibers thiab muaj qee yam ceev ntawm fiber ntau yog vim muaj ntau lub zog gravitational ntawm dye molecules thiab fiber ntau molecules. Lub hauv paus ntsiab lus ntawm dyeing thiab dyeing txheej txheem ntawm ntau yam dyes yog txawv heev vim cov yam ntxwv ntawm dyes thiab fibers, thiab tsis tau generalized, tab sis nyob rau hauv cov nqe lus ntawm lawv cov txheej txheem dyeing, lawv muaj peev xwm roughly muab faib ua peb theem pib.
1. Adsorption: Thaum cov fiber ntau muab tso rau hauv cov xim da dej, cov dye thawj zaug diffuses rau saum npoo ntawm fiber ntau, thiab tom qab ntawd maj mam hloov ntawm cov tshuaj mus rau saum npoo ntawm fiber ntau. Cov txheej txheem no hu ua adsorption. Nyob rau tib lub sijhawm, cov xim dye concentration ntawm cov fibers maj mam nce, thaum lub dye concentration nyob rau hauv cov tshuaj maj mam txo, thiab tom qab ib lub sij hawm, lub equilibrium lub xeev yog mus txog. Cov txheej txheem thim rov qab ntawm adsorption yog desorption, thiab adsorption thiab desorption tshwm sim ib txhij hauv cov txheej txheem dyeing.
2. Diffusion: Cov dye adsorbed rau ntawm fiber ntau diffuses mus rau hauv fiber ntau kom txog thaum lub dye concentration ntawm txhua feem ntawm fiber ntau zoo ib yam. Txij li cov dye concentration adsorbed rau ntawm fiber ntau yog ntau dua qhov dye concentration hauv fiber ntau, cov dye yog txhawb kom diffuse los ntawm fiber ntau mus rau fiber ntau sab hauv. Nyob rau lub sijhawm no, qhov diffusion ntawm cov dye rhuav tshem qhov pib tsim adsorption equilibrium, thiab cov dye hauv cov tshuaj yog txuas ntxiv adsorbed mus rau fiber ntau dua, thiab cov adsorption thiab desorption ncav cuag qhov sib npaug dua.
3. Fixation: Nws yog cov txheej txheem ntawm kev sib txuas cov dyes thiab fibers. Kev sib xyaw ntawm dyes thiab fibers yog txawv.
Peb theem saum toj no feem ntau sib koom ua ke hauv cov txheej txheem dyeing thiab tsis tuaj yeem sib cais tag nrho. Nws tsuas yog hais tias ib qho txheej txheem yeej muaj nyob rau hauv ib lub sij hawm ntawm dyeing.
