Abstract

The invention concerns the use of a fiber modified with functions capable of interacting with microbial cell wall proteins for immobilizing micro-organisms in hygiene products. Those functions are particularly capable of interacting with anionic groups and amine groups, and are especially cationic groups and aldehydes, respectively. The fibers may be synthetic or cellulosic. Also hygiene products containing these fibers are described.
