Abstract

L'invention concerne des produits à structure fibreuse jetables dans les toilettes, comprenant des produits de papier hygiénique. Comme mentionné dans la section relative au contexte, il existe une plage souhaitable relativement étroite de temps de flottation/coulage qui peut prédire la réussite d'une aptitude à être jeté dans les toilettes. Les structures fibreuses qui flottent peuvent avoir des difficultés à sortir d'une cuvette de toilettes. Et les structures fibreuses qui coulent trop rapidement peuvent provoquer un bouchon au point de sortie d'une cuvette de toilettes. Ainsi, la présente invention concerne des structures fibreuses et des produits de papier hygiénique les comprenant qui ne flottent pas mais coulent de façon suffisamment lente lorsqu'ils sont placés dans des toilettes de façon à ne pas provoquer de bouchon.
