Mechanical fastening system for absorbing articles

We describe herein a mechanical fastening system 5 for absorbing articles, such as disposable diapers (10) with an external layer or impermeable coating (12), an internal layer or permeable sheet (14) and an absorbing core of multiple layers sandwiched between the external coating (12) and the internal sheet (14), defining a frontal part (18) and a rear part (20) and a part between the legs (22) between the frontal and rear parts, the part between the parts with elastics (23) to adjust on the user's thigh region. In the rear part (20) of the waist region (24) of 15 the absorbing article, between the external (12) and internal (14) layers, the elastic elements are added and adhered to and, with the liberation, a contraction occurs, forming a continuous region of corrugated filaments or loop fibers (28), adequate for the fastening of a plurality of hooks (32) disposed on the frontal part (18) of the absorbing article (10).
