SHAPED CELLULOSIC FIBERS |
摘要 |
<p>SHAPED CELLULOSIC FIBERS Shaped cellulosic fibers are produced by nitrosating and dissolving a cellulosic material in an aprotic solvent selected from the group consisting of a dialkylacylamide and dimethylsulfoxide and regenerating the dissolved cellulose by contacting the cellulose solution with a regenerant. The regenerant is butanol, pentanol or benzyl alcohol where the solvent is a dialkylacylamide and propanol, butanol or benzyl alcohol where the solvent is dimethylsulfoxide. The fibers have a generally crenulated shape as regenerated and require no special spinnerette designs nor special spinning conditions.</p> |
