Claims (3)

1. Un procédé de préparation de fibres de polyoléfines uniformément hydrophiles et dispersables dans l'eau, caractérisé en ce que l'on forme une suspension aqueuse de fibres de polyoléfines crachées, on ajoute à celle suspension, tout en brassant, une solution aqueuse d'un réactif ionisé soluble dans l'eau capable d'être converti en particules solides hydratées d'une dimension submicronique, ce réactif ionisé étant un métal alcalin ou un sel ammoniaqué de cellophane, une cellophane modifiée ou un mélange de ceux-ci, et on ajoute ensuite à la dispersion de fibres ainsi formée un agent précipitant ionique pour le réactif ionisé, cet agent précipitant ionique étant de l'alun, de l'acide sulfurique, un mélange d'alun et d'acide sulfurique ou un sel de calcium ou de magnésium soluble dans l'eau de manière à effectuer ainsi la précipitation des particules solides hydratées de dimension submicronique sur la surface des fibres de polyoléfine.
2. Procédé suivant la revendication 1 caractérisé en ce que les fibres de polyoléfines crachées sont des fibres de polypropylène.
3. Un papier contenant les fibres de polyoléfines qui ont été préparées par le procédé suivant l'une ou l'autre des revendications 1 et 2.
