Classification Of Reactive Dyeing

Ho ea ka lihlopha tse fapaneng tse sebetsang, lidae tse sebetsang li ka aroloa ka mefuta e 'meli: mofuta oa symmetrical triazene le mofuta oa vinylsulfone.

Symmetric triazene type: Mofuteng ona oa lidae tse sebetsang, lik'hemik'hale tsa liathomo tse sebetsang tsa chlorine li sebetsa haholoanyane.Nakong ea ts'ebetso ea ho daea, liathomo tsa chlorine li nkeloa sebaka ke likhoele tsa cellulose sebakeng sa alkaline ebe li fetoha lihlopha.Boitšoaro pakeng tsa dae le fiber ea cellulose ke bimolecular nucleophilic substitution reaction.

Mofuta oa vinyl sulfone: vinyl sulfone (D-SO2CH = CH2) kapa β-hydroxyethyl sulfone sulfate.Nakong ea ts'ebetso ea ho daea, β-hydroxyethyl sulfone sulfate e phalla sebakeng sa alkaline ho theha sehlopha sa vinyl sulfone.Sehlopha sa vinyl sulfone se kopana le fiber ea cellulose ho kena karabelong ea nucleophilic ho etsa tlamo e kopanetsoeng.

Lidae tse peli tse sebetsang tse boletsoeng ka holimo ke mefuta e ka sehloohong ea lidae tse sebetsang tse nang le tlhahiso e kholo ka ho fetisisa lefatšeng.E le ho ntlafatsa lebelo la ho lokisa lidae tse reactive, lilemong tsa morao tjena ho 'nile ha kenngoa lihlopha tse peli tsa dae ka har'a molek'hule ea dae, e leng lidae tse peli tse sebetsang hantle.

Lidae tse sebetsang li ka aroloa ka lihlopha tse 'maloa ho latela lihlopha tsa tsona tse fapaneng tse sebetsang:

1. Dae e sebetsang ea mofuta oa X e na le sehlopha se sebetsang sa dichloro-s-triazine, e leng dae e sebetsang ka mocheso o tlase, e loketseng ho daea fiber ea cellulose ka 40-50 ℃.

2. Dae e sebetsang ea mofuta oa K e na le sehlopha se sebetsang sa monochlorotriazine, e leng dae e sebetsang ka mocheso o phahameng, e loketseng ho hatisa le ho daea pad ea masela a k'hothone.

3. Lidae tse sebetsang tsa mofuta oa KN li na le lihlopha tse sebetsang tsa hydroxyethyl sulfone sulfate, e leng lidae tse sebetsang ka har'a mocheso o bohareng.Mocheso oa ho daea ke 40-60 ℃, o loketse ho daea moqolo oa k'hothone, ho daea ka bongata bo batang, le khatiso ea dae e khutlisetsang morao joalo ka 'mala oa bokamorao;hape e loketse ho dauoa ha masela a hemp.

4. Dae e sebetsang ea mofuta oa M e na le lihlopha tse peli tse sebetsang hantle 'me ke tsa dae e sebetsang ka mocheso o bohareng.Mocheso oa ho daea ke 60°C.E loketse ho hatisa mocheso o mahareng le ho daea k'hothone le line.

5. Mofuta oa KE lidae tse sebetsang li na le lihlopha tse peli tse sebetsang hantle 'me ke tsa lidae tse sebetsang ka mocheso o phahameng, tse loketseng ho daea k'hothone le masela a line.

1. Dae e ka itšoara ka fiber ho etsa tlamahano ea covalent.Tlas'a maemo a tloaelehileng, motsoako ona o ke ke oa arohana, kahoo hang ha dae e sebetsang e dailoeng holim'a fiber, e tla ba le 'mala o motle oa ho itima lijo, haholo-holo phekolo ea metsi.Ho feta moo, fiber e ke ke ea robeha joaloka lidae tse ling tsa vat ka mor'a ho dauoa.

2. E na le ts'ebetso e ntle ea boemo, mebala e khanyang, khanya e ntle, e bonolo ho e sebelisa, chromatogram e feletseng, le theko e tlaase.

3. E se e ka hlahisoa ka bongata Chaena, e ka finyellang ka botlalo litlhoko tsa indasteri ea khatiso le ho daea;e na le mefuta e mengata ea tšebeliso, eseng feela bakeng sa ho daea likhoele tsa cellulose, empa hape le bakeng sa ho daea likhoele tsa protheine le masela a mang a kopantsoeng.
