N-methylolacrylamide에 의한 면직물에의 반응성기 도입
Introduction of Reactive Groups to Cotton Fabrics Using N-methylolacrylamide
초록
When cellulose is treated with N-methylolacrylamide(NMA) in the presence of acid catalysts, pendant C=C double bonds (vinyl group) are created on cellulose. These double bonds are capable of addition reaction with the residual hydroxyl group of cellulose fibers or other reactive groups of dyestuffs. In this study the effect of NMA concentration, amount of catalysts, and curing time was in vestigated when the C=C double bonds are introduced to cellulose using NMA. Furthermore the effect of NaOH concentration, reaction temperature and time was studied when the created C=C double bonds react with the unreacted hydroxyl groups of cellulose in the presence of NaOH catalysts.
