A hint on the correlation between cellulose fibers polymerization degree and their thermal and thermo-oxidative degradation
Original language description
The degree of polymerization (DP) is the main factor which plays a role in cellulose aging. The adverse consequence of cellulose fibers aging is the deterioration of mechanical and optical properties. Viscometry is a technique which is frequently used for determination of degree of polymerization of cellulose fibers. The aim of the work was to determine the degree of polymerization of cotton fabrics and to investigate the dependence of DP on number of washing and dying. Next task was to investigate if there exists a corellation between DP and results from thermal and thermo-oxidative degradation studied by methods of thermal analysis. First, the traditional viscometry was employed to determine DP of cellulose fibers. It has been demonstrated that number of washing and dying decreases the DP. In the second part the differential scanning calorimetry (DSC) and thermogravimetry (TG) were used. DSC provided values of combustion heat and TG allowed the detail evaluation of degradation steps;
