Dyeing accelerators yog cov khoom siv tshuaj reagents siv los txhim kho cov xim dyeing, txo lub sij hawm dyeing, thiab txo cov ntsiab lus dye residual. Lawv txhawb dye binding los ntawm kev kho cov zeta muaj peev xwm ntawm cov fiber ntau thiab cov dye los yog hloov cov fiber ntau cov khoom hluav taws xob. Cov nyhuv dyeing yog txiav txim los ntawm ntau npaum li cas, dyeing kub, thiab dye da dej pH. Cov khoom tseem ceeb muaj xws li ntsev, sodium sulfate, glacial acetic acid, thiab sulfuric acid, thiab hom tsim nyog (acidic, direct, los yog disperse dyes) tuaj yeem xaiv raws li hom fiber ntau.
Tus tshiab tus phooj ywg dyeing accelerator siv ib tug compound ntawm hloov kho chitosan, calcium chloride, thiab menthyl salicylate, muaj ob qho tib si tsis yog - tshuaj lom thiab biodegradable zog. Lub disperse dye low-kub dyeing accelerator BLB muaj cov tshuaj tsw qab ester thiab cov emulsifier complex, adsorbing dyes thiab o polyester fibers los ntawm hydrogen bonding. Dioctyl dimethyl ammonium bromide, siv los ua dyeing accelerator rau reactive dyes ntawm txhob lo lo ntxhuav, yuav tsum tsis muaj ntxiv inorganic ntsev thiab ua tiav ib tug dye uptake tus nqi ntawm 99.45%. Lub nonionic dyeing accelerator HDF yog siv rau kub -kub dyeing, txhim kho fixation thiab txo lub zog noj. Cov ammonia-dawb nitrogen-dawb dyeing accelerator ST373A tuaj yeem hloov urea hauv reactive dye printing.
