Acid Dyes

Hermeta Acid Dyes inowanzoiswa kune machira ari yakaderera pH.Iwo anonyanya kushandiswa kudhaya makushe, kwete machira ekotoni.

Asidhi madhayi ane anionic, anonyungudika mumvura uye anonyanya kuiswa kubva kune acidic bath.Aya madhayi ane mapoka ane acidic, akadai seSO3H neCOOH uye anoiswa pamvere dzemakwai, sirika uye naironi apo ionic bond inotangwa pakati peprotonated -NH2 boka refiber uye asidhi boka redhayi.Kumhanya kwekuwacha kwese kwakashata kunyangwe kupfava kuri nani.Sezvo dhayi uye faibha zvine zvakapesana nemagetsi, chiyero chekurova uye kutora kweasidhi dhayi pamafiber aya kunokurumidza;electrolyte padanho repamusoro inowedzerwa kunonoka kutora dhayi uye kugadzira mimvuri yakasimudzwa.Acid inogadzira cation pane fiber uye tembiricha inobatsira kutsiva isina kunaka chikamu cheasidhi neanionic dhayi mamorekuru.
