txheej txheem dyeing yuav tsum tso zas molecules hauv microstructure ntawm fiber. Cov dye molecules tuaj yeem thaiv kev ruaj ntseg los ntawm kev tsim cov ntawv cog lus covalent uas tshwm sim los ntawm cov tshuaj tiv thaiv ntawm cov khoom hloov ntawm cov molecules ntawm cov dye thiab fiber.
Dye molecular yog dab tsi?
Molecular Energy Levels
Dye molecules muaj loj molecular weights thiab muaj cov kab txuas txuas ntxiv ntawm ob daim ntawv cog lus. Cov molecules no tuaj yeem yaj rau hauv cov kuab tshuaj organic txaus (xws li ethanol, methanol, ethanol / dej, thiab methanol / dej) los yog muab tso rau hauv cov khoom matrix (organic, inorganic, lossis hybrid).
Dyeing txheej txheem yog dab tsi?
Ib txheej txheem dyeing yog kev sib cuam tshuam ntawm cov dye thiab fiber, nrog rau kev txav ntawm cov xim mus rau hauv ib feem ntawm cov fiber. Feem ntau, cov txheej txheem dyeing cuam tshuam nrog adsorption (hloov cov dyes los ntawm cov tshuaj aqueous mus rau fiber ntau) thiab diffusion (dyes diffused rau hauv fiber).
Yuav ua li cas peb thiaj tau cov xim thiab ntaub molecules ua li cas?
A siab pH yog txhua yam uas yuav tsum tau ua kom tau cov zas xim thiab cov cellulose npaj los ua. Sodium carbonate muaj zog dua li baking soda, yog li nws ua haujlwm zoo dua rau dyeing. Txhua yam peb yuav tsum tau ua kom muaj kev ruaj ntseg ntawm cov zas xim thiab cov paj rwb yog muab cov zas rau ntawm cov paj rwb thiab ntxiv cov xab npum ntxhua khaub ncaws
Dye molecules yog dab tsi?
Acidic dyes, basic dyes, azoic dyes, nitro dyes, vat dyes, mordant dyes, and sulfur dyes, thiab lwm yam yog hluavtaws dyes.
