Ukwahlukaniswa Kokudaya Okusebenzayo
Ngokusho kwamaqembu ahlukene asebenzayo, odayi abasebenzayo bangahlukaniswa ngezinhlobo ezimbili: uhlobo lwe-symmetrical triazene kanye nohlobo lwe-vinylsulfone.
Uhlobo lwe-Symmetric triazene: Kulolu hlobo lwamadayi asebenzayo, izakhiwo zamakhemikhali zama-athomu e-chlorine asebenzayo asebenza kakhulu.Phakathi nenqubo yokudaya, ama-athomu e-chlorine athathelwa indawo imicu ye-cellulose ku-alkaline medium futhi abe amaqembu ashiyayo.Ukusabela phakathi kodayi kanye nefayibha ye-cellulose kuwukusabela kwe-bimolecular nucleophilic substitution.
Uhlobo lwe-vinyl sulfone: i-vinyl sulfone (D-SO2CH = CH2) noma i-β-hydroxyethyl sulfone sulfone.Phakathi nenqubo yokudaya, i-β-hydroxyethyl sulfone sulfate idlula endaweni ene-alkaline ukuze yakhe iqembu le-vinyl sulfone.Iqembu le-vinyl sulfone lihlangana ne-cellulose fiber ukuze libhekane ne-nucleophilic add reaction ukuze lenze isibopho esihlangene.
Odayi ababili abasebenzayo okukhulunywe ngabo ngenhla bayizinhlobo eziyinhloko zodayi abasebenzayo abanomkhiqizo omkhulu kakhulu emhlabeni.Ukuze kuthuthukiswe izinga lokulungisa odayi abasebenzayo, amaqembu amabili asebenzayo angeniswe engqamuzaneni likadayi eminyakeni yamuva, okungodayi abakabili abasebenzayo.
Odayi abasebenzayo bangahlukaniswa ngochungechunge oluningana ngokuya ngamaqembu abo asebenzayo ahlukile:
1. Udayi osebenzayo wohlobo lwe-X uqukethe iqembu elisebenzayo le-dichloro-s-triazine, okuwudayi osebenzayo onethempelesha ephansi, ofanele ukudaya i-cellulose fiber ku-40-50℃.
2. Udayi osebenzayo wohlobo lwe-K uqukethe iqembu elisebenzayo le-monochlorotriazine, okuwudayi osebenzayo oshisa kakhulu, ofanele ukuphrinta nokudaywa kwephedi yezindwangu zikakotini.
3. Odayi abasebenzayo bohlobo lwe-KN baqukethe amaqembu asebenzayo e-hydroxyethyl sulfone sulfate, okuwudayi osebenza ngokushisa ophakathi nendawo.Izinga lokushisa lokudaya lingu-40-60 ℃, lilungele ukudaywa kwe-cotton roll, ukudaya okuningi okubandayo, nokuphrinta kodayi okubuyela emuva njengombala wangemuva;futhi ilungele ukudaywa kwezindwangu ze-hemp.
4. Udayi osebenzayo wohlobo lwe-M uqukethe amaqembu asebenza kabili futhi ungowodayi osebenza ngokushisa omaphakathi.Izinga lokushisa lokudaya lingu-60°C.Ifanele ukuphrinta lokushisa okuphakathi kanye nokudaya ukotini nelineni.
5. Odayi abasebenzayo bohlobo lwe-KE baqukethe amaqembu asebenza kabili futhi bangabakadayi abasebenzisa izinga lokushisa eliphezulu, abafanele ukudaya izindwangu zikakotini nelineni.
Izici
1. Udayi ungasabela ngefiber ukuze wakhe isibopho esiqinile.Ngaphansi kwezimo ezijwayelekile, le nhlanganisela ngeke ihlukanise, ngakho-ke uma udayi osebenzayo usudayiwe ku-fiber, uzoba nokushesha kombala okuhle, ikakhulukazi ukwelashwa okumanzi.Ngaphezu kwalokho, i-fiber ngeke ibe brittle njengabanye odayi be-vat ngemva kokudaywa.
2. Inokusebenza kahle kokulinganisa, imibala egqamile, ukukhanya okuhle, kulula ukuyisebenzisa, ichromatogram ephelele, nezindleko eziphansi.
3. Ingavele ikhiqizwe ngobuningi eShayina, engahlangabezana ngokugcwele nezidingo zemboni yokunyathelisa nokudaya;inokusetshenziswa okuhlukahlukene, hhayi nje ukudaya imicu ye-cellulose, kodwa nasekudayeni imicu yamaprotheni nezinye izindwangu ezihlanganisiwe.
Singabahlinzeki be-Reactive Dyes.Uma unentshisekelo ngemikhiqizo yethu, sicela ukhululeke ukuxhumana nathi.
