Evaluating the addition of cellulose nano fibers to reinforce of high yield kraft pulp produced from P.deltoides clone 69-55
In this research, capacity of cellulose nanofibers to reinforce of high yield kraft pulp produced (HYKP) from Populus deltoides clone 69-55 for making unbleached top kraft liner (UTKL) was investigated. The variable conditions of cooking were included the cooking time and temperature each one in two...
