An odor-inhibiting fiber having a cellulosic fiber and an odor-inhibiting formulation. The odor-inhibiting formulation may contain an odor-inhibiting agent, such as a biocide, an enzyme, a urease inhibitor. The odor-inhibiting formulation also may contain a liquid carrier such as a hydrophobic or hydrophilic organic liquid, or a mixture of a hydrophobic and hydrophilic organic liquid. The cellulosic fiber is impregnated with the odor-inhibiting formulation to produce fiber having odor-inhibiting characteristics. The resultant odor-inhibiting fiber is useful in making absorbent articles with odor-inhibiting characteristics. The fiber of the embodiments prevents odor by inhibiting bacteria growth and ammonia production, especially when used in an absorbent article such as a diaper or adult incontinence device. L'invention concerne une fibre inhibant les odeurs et constituée d'une fibre cellulosique et d'une formulation inhibant les odeurs. Cette formulation peut contenir un agent inhibant les odeurs, tel qu'un biocide, une enzyme, un inhibiteur d'uréase. La formulation inhibant les odeurs peut également contenir un excipient liquide, tel qu'un liquide organique hydrophobe ou hydrophile, ou un mélange de ce liquide organique hydrophobe ou hydrophile. La fibre cellulosique est imprégnée de la formulation inhibant les odeurs afin de produire une fibre présentant des caractéristiques inhibant les odeurs. La fibre inhibant les odeurs obtenue est utile dans la fabrication d'articles absorbants auxquels elle confère des caractéristiques d'inhibition d'odeur. La fibre de cette invention prévient les odeurs en inhibant la prolifération bactérienne et la production d'ammoniac, notamment lorsqu'elle est utilisée dans un article absorbant tel qu'une couche culotte ou une culotte d'incontinence pour adulte.
