Reactive Dyeing ine yakanaka kwazvo dissolution state mumvura.Reactive madhayi anonyanya kuvimba neboka re sulfonic acid pamorekuru wedhayi kunyungudika mumvura.Kune meso-temperature reactive dyes ane vinylsulfone mapoka, kunze kwemapoka e-sulfonic acid Mukuwedzera, ayo β-ethylsulfone sulfate iboka rakanaka kwazvo rekunyungudutsa.Mumushonga wemvura, maion sodium paboka re sulfonic acid neboka re -ethylsulfone sulfate rinoita hydration reaction kuti dhayi iumbe anion uye inyunguduke mumvura.Kudhayiwa kwedhayi reactive kunovimba neiyoni yakaipa yedhayi kuti idhayirwe kune fiber.Kunyungudika kwedhayi dzinoshanda zvinodarika 100 g/L.
Kunyungudika kwedhayi zhinji ndeye 200-400 g/l, uye mamwe madhayi anogona kutosvika 450 g/l.
Asi mukugadzira dhayi, kunyungudika kwedhayi kunodzikira nekuda kwezvikonzero zvakasiyana (kana kunyange kunyungudika zvachose).
Kana iyo solubility yedhayi inoderera, chikamu chedhayi chinoshanduka kubva kune imwe yakasununguka isina ion ion kusvika kune zvidimbu, uye kubhadharisa repulsion pakati pezvimedu kunoderedzwa zvakanyanya.
Zvimedu uye zvimedu zvinokwezva mumwe nemumwe kuti aumbe agglomeration
Mune rudzi urwu rwekubatanidza, zvidimbu zvedhayi zvinoungana kuita aggregates, zvino kuita aggregates, uye pakupedzisira kuita flocs.Kunyangwe iyo floc iri yakasununguka muunganidzwa, nekuda kwemagetsi kaviri layer yakaumbwa neakanaka uye yakaipa mhosva dzakapoteredzwa, zvakaoma kuti shear simba reiyo general dhayi doro riparare, uye floc iri nyore pamucheka.Kunaya pamusoro pemvura, zvichikonzera kusvibiswa kwepamusoro kana kusvibiswa.
Kana dhayi yave nekubatana kwakadaro, kumhanyisa kweruvara kuri pachena kunodzikira, uye kuchakonzera madhigirii akasiyana emavara, mavara, uye mavara.Kune mamwe madhayi, maflocs anozowedzera kukurumidza kuungana pasi pesimba rekuveura dhayi doro, zvichikonzera kupera simba uye salting kunze.Kana salting yabuda, ruvara rwakadhayiwa ruchave rwakanyanya kujeka, kana kuti rusina kudhayiwa, kunyangwe rwukadhayiwa, ruchave rwakakomba mavara uye mavara.
Reactive Dyeing
Zvikonzero zvekusanganiswa kwedhayi
Chikonzero chikuru ndeye electrolyte.Mukugadzira dhayi, iyo huru electrolyte ndiyo dhayi inomhanyisa (sodium sulphate hupfu nemunyu).Iyo dhayi inomhanyisa ine sodium ion, uye iyo sodium ion yakaenzana mumorekuru wedhayi yakadzikira pane yedhayi inomhanyisa.Iyo yakaenzana nhamba ye sodium ion uye yakajairwa kuwanda kweiyo accelerator panguva yakajairwa kudhaya maitiro haizove nerubatsiro rwakawanda pakunyungudika kwedhayi mubhati redhayi.
Nekudaro, kana huwandu hweiyo dhayi-inokurudzira agent ichiwedzera, kuunganidzwa kweiyo sodium ion mumhinduro kunowedzerawo.Yakawandisa sodium ions inodzivirira iyo ionization yesodium ions pamapoka akanyungudika emamorekuru edhayi, nekudaro ichidzikisa kunyungudika kwedhayi.
Kana huwandu hweiyo accelerator yedhayi inodarika 200 g/L, madhayi mazhinji anozopinda madhigirii akasiyana ekuunganidza.
Kana huwandu hweiyo accelerator yedhayi inodarika 200 g/L, madhayi mazhinji anozopinda madhigirii akasiyana ekuunganidza.
Kana kusanganiswa kwedhayi-inokurudzira agent inodarika 250 g / L, dhigirii yeagglomeration ichawedzera, kutanga kugadzira agglomerates, uye nekukurumidza kugadzira agglomerates uye floccules pasi peshear simba remhinduro yedhayi.Kune mamwe madhayi ane yakaderera solubility, Chikamu chayo munyu kunze uye kunyange dehydrated.
Madhayi ane akasiyana mamolecular maitiro ane akasiyana anti-aggregation uye salting-out resistance.Iyo yakaderera kunyungudika, kunowedzera iyo anti-aggregation uye salting-out kuramba.
Kunyungudika kwedhayi kunonyanya kutsanangurwa nehuwandu hwemapoka e-sulfonic acid mumorekuru wedhayi uye nhamba ye-β-ethylsulfone sulfates.
Panguva imwecheteyo, iyo yakakura hydrophilicity yemorekuru wedhayi, iyo yakanyanya kunyungudika, uye yakaderera iyo hydrophilicity, inodzika iyo solubility.(Semuyenzaniso, madhayi ane azo dhizaini anowedzera hydrophilic kupfuura dhayi ane heterocyclic chimiro.) Uyezve, iyo yakakura iyo molecular chimiro chedhayi, yakaderera kunyungudika, uye madiki mamorekuru maitiro, anowedzera kunyungudika.
Isu tiri Reactive Dyeing mutengesi.Kana iwe uine chero chinodiwa chezvigadzirwa zvedu, ndapota inzwa wakasununguka kutibata nesu.
