Ukwahlukaniswa Kokudaya Okusebenzayo

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.Ngesikhathi senqubo yokudaya, ama-athomu e-chlorine athathelwa indawo imicu ye-cellulose ku-alkaline medium futhi abe amaqembu ashiyayo.Ukusabela phakathi kodayi kanye ne-cellulose fiber 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 fibre ukuze libhekane nokusabela kwe-nucleophilic Add to make a covalent bond.

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 onezinga lokushisa eliphansi, olungele ukudaywa 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 abasebenzayo phakathi kwezinga lokushisa.Izinga lokushisa lokudaya lingu-40-60 ℃, lilungele ukudaywa kwe-cotton roll, ukudaya okuningi okubandayo, nokuphrinta udayi obuyela emuva njengombala wangemuva;futhi ilungele ukudaywa kwezindwangu ze-hemp.

4. Udayi osebenzayo wohlobo lwe-M uqukethe amaqembu asebenza kabili futhi ungowodayi osebenzayo osebenzayo wokushisa 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 kuphela ukudaya imicu ye-cellulose, kodwa futhi nokudaya imicu yamaprotheni nezinye izindwangu ezihlanganisiwe.

Singabahlinzeki be-Reactive Dyes.Uma unentshisekelo ngemikhiqizo yethu, sicela ukhululeke ukuxhumana nathi.
