The both films prepared by removing Na2SO4 or CH3COONa in water had a water-resistance property. The degree of crystallization of the films increased with an increase of the contents of Na2SO4 and CH3COONa in the solutions up to 0.05 and 0.1wt%, respectively. However the melting temperature (226 - 228□) was independent of the content ofNa2SO4 and CH3COONa in the solutions. The draw ratio and tensile modulus of the films prepared from the solutions with 0.01wt% Na2SO4 and 0.1wt% CH3COONa were higher about ca. 1.6 times than that of the films obtained from an aqueous solution., Article, 先進ファイバー工学研究教育拠点研究成果報告書 11: 111-111(2005)}, title = {15-5-1 : 生体・環境適用型パフォーマンス繊維の開発}, year = {2005} }
