Abstract

Un feutre à couture pour fabriquer du papier (10), lequel comprend une couche de base (30) ayant une partie couture, une couche de fibres aboutée du côté feuille continue humide (20), formée sur la surface du côté feuille continue humide de la couche de base (30), et une couche de fibres aboutée du côté de la presse (21), formée sur la surface du côté de la presse de la couche de base (30), où la couche de fibres aboutée du côté feuille continue humide (20) comprend des fibres composites âme/gaine (41), formées par un ingrédient de base comprenant un nylon macromoléculaire ayant une viscosité absolue de 80 mPa•s ou supérieure et par un ingrédient de gaine comprenant un nylon ayant un point de fusion inférieur à celui de l'ingrédient de base. L'ingrédient de gaine pour les fibres composites de base-gaine (41) fond pour former une couche de fibres de réseau pour rendre la couche de fibres aboutée du côté feuille continue humide (20) dense. Du fait que de ce fait la couche de fibres aboutée du côté feuille continue humide (20) sert de barrière, l'eau contenue dans la couche du côté de la presse est moins enclin à s'écouler vers le côté feuille continue humide. Certes, un phénomène de nouvelle humidification est empêché de se produire. A cause de l'utilisation d'un ingrédient à haute viscosité, c'est-à-dire, un nylon à haute viscosité, comme l'ingrédient de base pour les fibres composites de base-gaine (41), le feutre peut associer de façon bien équilibrée lissé de surface, absence de tendance au débourrage /résistance à l'usure et résistance à la fatigue par compression.
