Abstract (en)
Sheets based on cellulosic fibres produced by a papermaking route containing inorganic fibres. According to the invention the papermaking pulp contains inorganic fibres which exhibit the characteristics of the fibres intended for thermal insulation, namely: they have a mean diameter of between 3 and [illegible] micrometres and are in the form of a wool. The sheets obtained according to the invention have, in particular, the advantage of exhibiting an improved "handle".
Abstract (fr)
L'invention est relative aux feuilles à base de fibres cellulosiques produites par voie papetière et contenant des fibres minérales. Selon l'invention, la pâte papetière contient des fibres minérales qui présentent les caractéristiques des fibres destinées à l'isolation thermique, à savoir: ont un diamètre moyen compris entre 3 et 8 micromètres et sont sous forme d'une laine. Les feuilles obtenues selon l'invention ont, notamment, pour avantage de présenter une "main" améliorée.
