Skinless shaped articles having increased specific surface area and based on cellulose esters, including both solid and hollow fibers (1A), can be produced with at least one surface having a striated or fibrous appearance (1C) and a cellular interior structure (1B) by extruding a spinning solution comprising a cellulose ester and a solvent therefor directly into an aqueous bath, wherein the residual content of solvent in the bath is maintained at a concentration below a critical level, preferably less than about 10 weight percent. |
