(FR) FEUILLE ET PROCÉDÉ DE FABRICATION DE FEUILLE
(JA) シートおよびシートの製造方法
Abstract:
(EN) The present invention addresses the problem of providing a composite sheet provided with all of water repellency, water resistance, transparency, and mechanical strength. The present invention relates to a sheet including a fiber layer and a coating layer on the fiber layer, wherein the fiber layer includes 60 mass% or more of fine fibrous cellulose, the fibrous fiber cellulose having a fiber width of 1000 nm or less, the haze of the sheet is 20% or less, and the water contact angle of a surface at the coating layer side of the sheet 30 seconds after distilled water has dropped thereon is 70 degrees or more.
(FR) La présente invention vise à fournir une feuille composite ayant à la fois un caractère hydrofuge, une résistance à l'eau, une transparence et une résistance mécanique. La présente invention concerne une feuille comprenant une couche de fibres et une couche de revêtement sur la couche de fibres, la couche de fibres comprenant 60 % en masse ou plus de cellulose fibreuse fine, la fibre de cellulose fibreuse ayant une largeur de fibre de 1 000 nm ou moins, le voile de la feuille étant inférieur ou égal à 20 %, et l'angle de contact d'eau d'une surface sur le côté de couche de revêtement de la feuille 30 secondes après le dépôt d'eau distillée sur cette dernière étant de 70 degrés ou plus.
(JA) 本発明は、撥水性、耐水性、透明性及び機械的強度の全てを兼ね備えた複合シートを提供することを課題とする。本発明は、繊維層と、繊維層上にコート層を有するシートであって、繊維層は、繊維幅が1000nm以下の微細繊維状セルロースを60質量%以上含み、シートのヘーズが20%以下であり、シートのコート層側の表面の蒸留水滴下30秒後の水接触角が70度以上であるシートに関する。
