METHOD FOR THE MANUFACTURE OF AN EXTRUDED LYOCELL ARTICLE

摘要

Cellulose is exposed to high-energy radiation at a dosage in the rampe 1-4 kGy and then dissolved in an aqueous tertiary amine N-oxide solvent. The resulting solution is extruded through a die to form an extruded precursor, which is then washed and dried to form extruded lyocell articles, such as fibres and films. In a preferred embodiment, only part of the cellulose is irradiated.
