Title
(EN) FLUSHABLE BODY FLUID ABSORBENT COMPOSITE
(FR) COMPOSITE ABSORBANT DE FLUIDES CORPORELS POUVANT ÊTRE JETÉ DANS LES TOILETTES
Abstract
(EN)
A flushable bodily liquid absorbent composite product, having a bodily liquid absorbent core, a moisture barrier layer applied to a garment side of the core, a film moisture break and a tissue backing layer.The tissue backing layer is readily soluble in water and the moisture barrier layer and the film moisture break are readily soluble in cold water. The use of the film moisture break is to absorb small amounts of moisture that is transferred through the moisture barrier in order to prevent weakening of the backing layer and prevent the transfer of positioning adhesive to the consumers garments. Preferred moisture barrier comprises polyvinyl alcohol and the preferred moisture break comprises carboxymethylcellulose or polyacrylimide.
(FR)
L'invention porte sur un produit composite absorbant les liquides corporels pouvant être jeté dans les toilettes, comportant un cœur absorbant les liquides corporels, une couche barrière contre la moisissure appliquée à un côté vêtement du cœur, un dispositif de coupure de l'humidité par film et une couche de support en tissu. La couche de support en tissu est facilement soluble dans l'eau et la couche barrière contre l'humidité et le dispositif de coupure de l'humidité par film sont facilement solubles dans l'eau froide. L'utilisation du dispositif de coupure de l'humidité par film sert à absorber de petites quantités d'humidité qui sont transférées à travers la barrière contre l'humidité afin d'empêcher un affaiblissement de la couche de support et empêcher le transfert d'un adhésif de positionnement vers les vêtements du consommateur. La barrière contre l'humidité préférée comprend un alcool polyvinylique et le dispositif de coupure de l'humidité préféré comprend de la carboxyméthylcellulose ou du polyacrylimide.
