Preparation of cellulose carbamate, its properties and applications
A review of literature has been presented concering a new derivative of cellulose — cellulose carbamate. The conditions of synthesis of this product in the reaction of cellulose with urea or with a mixture of urea and biuret have been discussed, its IR- and ISC-NMR-spectra presented, manufacturing technologies of fibres from cellulose carbamate characterized. The main mechanical properties of these fibres have been presented. The competitiveness of forming processes of cellulose carbamate fibres and viscose fibres has been emphasized.
