23051 I-ejenti yokulungisa i-Acid
Izici & Izinzuzo
- Ingathuthukisa ukushesha kombala wokuwasha.
- Ukushintsha kombala okuncane kakhulu.Ifanele udayi we-acid fluorescent.
- Akuthinti umthunzi wombala.
- Umbala omncane kakhulu uyafiphala kanye nombala oshintshashintshayo.
- Impahla enhle yokunqanda ukubola.Ingavimbela ukungcolisa izingxenye ezimhlophe zezindwangu eziphrintiwe inayiloni.

Odayi abasebenzayo
Laba bodayi bakhiqizwa ukusabela kukadayi we-dichloro-s-triazine one-amine emazingeni okushisa endaweni engu-25-40°C, okuholela ekususweni kwenye yama-athomu e-chlorine, kukhiqizwe i-monochloro-s-triazine engasabeli kahle. (MCT) udayi.
Laba bodayi basetshenziswa ngendlela efanayo ku-cellulose ngaphandle kokuthi, njengoba bengasebenzi kancane kunodayi be-dichloro-s-triazine, badinga izinga lokushisa eliphezulu (80°C) kanye ne-pH (pH 11) ukuze kulungiswe udayi ku-cellulose ukuze zenzeka.
Lezi zinhlobo zodayi zinama-chromogen amabili namaqembu amabili asebenzayo e-MCT, ngakho-ke anamandla aphezulu kakhulu efayibha uma kuqhathaniswa nodayi abalula bohlobo lwe-MCT.Lokhu kukhula kokuqina kuzivumela ukuthi zifinyelele ukukhathala okuhle kakhulu ku-fiber ngezinga lokushisa elikhethwayo lokudaya elingu-80°C, okuholela kumanani okulungisa angama-70-80%.Odayi balolu hlobo bebedayiwe futhi basamakethwa ngaphansi kohlu lwe-Procion HE lodayi abaphuma kahle kakhulu.
Lawa madayi aqaliswa nguBayer, manje uDystar, ngaphansi kwegama elithi Levafix E, futhi asekelwe endandatho ye-quinoxaline (Fig. 1.9).Asebenza kancane kancane uma eqhathaniswa nodayi be-dichloro-s-triazine futhi asetshenziswa ku-50°C, kodwa asengozini yokuthola i-hydrolysis ngaphansi kwezimo ezine-asidi.
