Title (EN) NOVEL PAPER AND METHOD OF MANUFACTURING THEREOF
(FR) NOUVEAU PAPIER ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract: front page image
(EN)The invention relates to a method for manufacturing nanostructured paper or board and a novel paper or board. The method comprises providing a liquid suspension of nanocellulose-containing material, forming a web from the suspension and drying the web in order to form paper or board. According to the invention, the water content of the suspension at the time of beginning of the drying is 50 % or less by weight of liquids so as to form a paper or board having an average pore size between 200 and 400 nm. By means of the invention, very opaque paper, for example for printing applications, can be manufactured with low energy consumption.
(FR)La présente invention concerne un procédé de fabrication de papier ou de carton nanostructuré et un nouveau papier ou carton. Le procédé consiste à fournir une suspension liquide de matière qui contient de la nanocellulose, à former une bande continue à partir de la suspension et à sécher la bande continue afin de former du papier ou du carton. Selon l'invention, la teneur en eau de la suspension au début du séchage est inférieure ou égale à 50 % en poids de liquides pour former un papier ou un carton qui possède une taille moyenne des pores entre 200 et 400 nm. L'invention permet de fabriquer un papier très opaque, par exemple pour des applications d'impression, avec une basse consommation d'énergie.
