Title (EN) WATER-DISINTEGRABLE SHEET AND METHOD FOR PRODUCING WATER-DISINTEGRABLE SHEET
(FR) FEUILLE DÉSINTÉGRABLE DANS L'EAU ET PROCÉDÉ DE PRODUCTION DE FEUILLE POUVANT SE DÉSINTÉGRER DANS L'EAU
(JA) 水解性シート及び当該水解性シートの製造方法
Abstract:
(EN) This water-disintegrable sheet is obtained by impregnating a base paper sheet with an aqueous agent, wherein: the base paper sheet has a weight per unit area of 30-150 gsm, and contains a water-soluble binder (CMC) and cellulose nanofibers (CNF); and the aqueous agent contains a cross-linking agent capable of cross-linking with the water-soluble binder. According to this configuration, the present invention is able to provide, while maintaining operability and productivity, a water-disintegrable sheet having an improved wet strength and a production method for the water-disintegrable sheet.
(FR) Cette feuille désintégrable dans l'eau est obtenue par imprégnation d'une feuille de papier de base avec un agent aqueux : la feuille de papier de base a un poids par unité de surface de 30 à 150 gsm, et contient un liant soluble dans l'eau (CMC) et des nanofibres de cellulose (CNF); et l'agent aqueux contient un agent de réticulation capable de réticuler avec le liant soluble dans l'eau. Selon cette configuration, la présente invention est capable de fournir, tout en maintenant l'exploitabilité et la productivité, une feuille pouvant se désintégrer dans l'eau ayant une résistance à l'état humide améliorée et un procédé de production de la feuille pouvant se désintégrer dans l'eau.
(JA) 原紙シートに対して水性薬剤を含浸させた水解性シートであって、前記原紙シートは、目付量が30~150gsmであり、水溶性バインダー(CMC)を含有するとともに、セルロースナノファイバー(CNF)を含有し、前記水性薬剤は、水溶性バインダーと架橋する架橋剤を含んでいる。これにより、操業性・生産性を維持しつつ、湿潤強度を向上させた水解性シート及び当該水解性シートの製造方法を提供することができる。
