Abstract
From the studies on the relationship between analytical charactors of wood pulp comparing with cotton linter and qualities of cuprammonium rayon from them, the folowing three points are discussed;
1) α-cellulose content of wood pulp for cuprammonium rayon has more important meaning than that of viscose rayon. It is due to the difference between the processes of cuprammonium and viscose rayon.
2) Hot alkali (10% KOH) solubility suggests the easily destroyable amount of cellulose of wood pulp in cuprammonium solution. 10% KOH solubility is therefore very important, charcterizing quality of wood pulp for cuprammonium rayon. It is matter of a great interest, whether such wood pulp may be produced or not, which shows the same behavior in hot alkali solution as in cotton linter.
3) Turbidities of dissolved cellulose by acetylation of varous wood pulp were in good accordance with suitabilities to wood pulp for cuprammonium rayon.
