Abstract

L'invention porte sur un produit fibreux désodorisant qui présente une vitesse de désodorisation permettant une désodorisation rapide de diverses mauvaises odeurs dans le domaine des soins infirmiers et un taux de désodorisation élevé, ainsi qu'une excellente durabilité au lavage par rapport au taux de désodorisation. Ce produit fibreux désodorisant, qui est formé de cristaux poreux inorganiques portés sur la surface et à l'intérieur de fibres de cellulose, est caractérisé en ce qu'il a sur la surface et/ou à l'intérieur un type ou au moins deux types de substances désodorisantes choisies dans un groupe composé de (a)-(e) : (a) un composé de dioxyde de silicium et d'oxyde de zinc (b) un composé de silice amorphe et/ou de silice alumine et de phyllosilicate et/ou de phyllosilicate d'aluminium (c) un composé polyhydrazide (d) un acide polycarboxylique et/ou un polycarboxylate (e) du polyphénol
