Abstract:
(EN) Provided is a method for producing a water-insoluble moulded body which maintains the inherent properties of a polyanionic polysaccharide used as a starting material thereof, exhibits high safety due to not needing the use of a chemical crosslinking agent, and exhibits moderate pliability (flexibility), stretchability, and adhesiveness. The method for producing the water-insoluble moulded body is provided with a step in which a starting material moulded body comprising a starting material including a water-soluble salt of a polyanionic polysaccharide, and at least 0.2 mass% of an acid component, or a starting material moulded body comprising a starting material including a water-soluble salt of a polyanionic polysaccharide, and an alcohol (excluding glycerin), is treated with a treatment liquid including an acid anhydride, to make the starting material moulded body water-insoluble.
(FR) L’invention fournit un procédé destiné à fabriquer un corps moulé non soluble dans l’eau dans lequel les caractéristiques d’origine d’un polysaccharide anionique constituant une matière première sont préservées, et simultanément la mise en œuvre d’un agent de réticulation chimique n’étant pas nécessaire, la sécurité est accrue, et qui présente une souplesse (flexibilité), une élasticité et des propriétés de collage adéquates. Le procédé de fabrication de corps moulé non soluble dans l’eau de l’invention présente une étape au cours de laquelle un corps moulé matière première constitué d’une matière première comprenant un sel soluble dans l’eau de polysaccharide anionique et au moins 0,2% en masse d’un composant acide, ou un corps moulé matière première constitué d’une matière première comprenant un sel soluble dans l’eau de polysaccharide anionique et un alcool (glycérine exclue), est traité au moyen d’un liquide de traitement contenant un anhydride acide, et le corps moulé matière première est ainsi rendu non soluble dans l’eau.
(JA) 原料であるポリアニオン性多糖類本来の特性が保持されているとともに、化学架橋剤を用いる必要がないため安全性が高く、かつ、適度な柔軟性(可とう性)、伸縮性、及び貼り付き性を有する水不溶性成形体を製造する方法を提供する。ポリアニオン性多糖類の水溶性塩と、0.2質量%以上の酸成分とを含有する原材料からなる原料成形体、又はポリアニオン性多糖類の水溶性塩と、アルコール類(グリセリンを除く)とを含有する原材料からなる原料成形体を、酸無水物を含む処理液で処理し、原料成形体を水不溶化させる工程を有する水不溶性成形体の製造方法である。
