Regarding a tampon, which can be manufactured of the same raw materials, by means of the same machines and by means of essentially the same steps like the commercially attractive known tampons, it is the purpose of the invention to improve its capability of retaining the fluid when inserted into each vaginal cavity and to prevent migration of fluid in both directions, namely from the vaginal cavity and also from outside into said vaginal cavity, wherein simultaneously also the interconnection between the fibers and the withdrawal string should be improved, and disinfecting effect should be achieved. To this aim, such tampon is furnished with a barrier (4), which is foreseen adjacent to the rear end portion (3) of the tampon, which prevents migration of fluid along the tampon, namely in one or another direction along the longitudinal geometric axis (0) of the tampon, wherein said barrier (4) is formed by means of a highly compressed area on the fibrous band (1), which is located at a pre-determined distance (L) apart from the rear end portion (3) of the tampon, wherein the density of fibers within said area is at least three times greater than in residual portions of the fibrous band (1) i.e. of the tampon and amounts at least approximately 2 g/cm3. The invention also includes a process for manufacturing such tampon.Linvention concerne un tampon qui peut être fabriqué à base de mêmes matières premières, au moyen de mêmes machines et essentiellement de mêmes étapes que les tampons connus et commercialement attrayants. Lobjectif de la présente invention consiste à améliorer la capacité de rétention de liquide du tampon lorsquil est inséré dans une cavité vaginale et de prévenir la migration de fluide dans les deux sens, notamment depuis la cavité vaginale et aussi depuis lextérieur dans ladite cavité vaginale, tout en améliorant linterconnexion entre les fibres et la corde de retrait et tout en obtenant un effet désinfectant. A cette fin, le tampon est doté dune barriè
