PRACTICAL conversion of wood pulp to a product that resembles cotton cellulose is a definite possibility, says Bengt G. Rånby of the State University College of Forestry at Syracuse University. An important difference between cotton and wood cellulose is the greater number of weak links in the latter, says Rånby. This would account for the higher stability of cotton and the greater ease with which wood pulp hydrolyzes. While both cotton pulp and wood pulp are used to make cellulose products, such as rayon and acetate, cotton pulp is preferred for some premium products where the utmost strength is required, such as sausage casings and some tire cord. Cotton pulp costs only about 5% more than wood pulp, but the ability to upgrade wood pulp to cotton quality would have real significance. Looking for the reason for weak links in wood pulp, Rånby, until recently at American Viscose, and R. H. Marchessault of ...
