ABSTRACT:
In a method for manufacturing cellulose membranes in the form of flat films, tubular films, or hollow filaments with improved biocompatibility, cotton fibers, in particular linters, are treated in alkaline liquor in a single-stage process with gaseous molecular oxygen. In addition, the invention relates to cotton fibers prepared in this manner, especially linters, membranes made therefrom, and their use for hemodialysis.
