· Solubility Yam ntxwv: Nws dissolves nyob rau hauv ib tug sodium sulfide tov (ib kauj ruam tseem ceeb ntawm cov txheej txheem dyeing). Thaum tov nrog concentrated sulfuric acid, nws hloov violet -xiav, thiab raws li dilution, nws tsim ib tug xiav -dub precipitate.

· Cov ntawv thov tseem ceeb: Nws yog siv tshwj xeeb rau dyeing thiab luam ntawv paj rwb, linen, thiab viscose fibers. Raws li qhov ntxoov ntxoo ntawm xiav, nws muaj nyob rau hauv specifications xws li BN (ntsuab ntxoov ntxoo) thiab RN (reddish ntxoov ntxoo).

· Dyeing Mechanism: Raws li cov tshuaj zawv plaub hau, nws yog thawj zaug uas siv cov tshuaj txo qis (xws li sodium sulfide) kom nws nkag mus rau hauv cov fiber ntau. Tom qab ntawd nws tau tsim thiab kho los ntawm oxidation (siv cua lossis hydrogen peroxide).

· Tom qab-Kev Kho Mob: Feem ntau tom qab- kev kho mob suav nrog kev tiv thaiv- kev sib tw ua tiav (xws li siv urea) los tiv thaiv cov fiber ntau los ntawm nkig thaum khaws cia, lossis siv cov tshuaj kho kom zoo dua cov xim ceev.
