The agent(s) is/are adhered to the substrate in such a manner that they are not released from the textile even if the textile is wetted or washed, so that the textile is reusable. Washability and/or usability of the textile are improved where one or more hydrophilic and/or stain release agents are ad- hered to the textile. The substrate can be used, e.g., in a re- usable sanitary napkin or other hygiene product. The structure of the hygiene product is disclosed, together with a process of attaching the different layers of the hygiene product together by ultrasonic welding. The invention further relates to a meth- od of finishing a substrate by applying and binding antimicro- bial and/or hydrophilic and/or stain release agents to the sub - strate so that the agents are essentially irreversibly adhered to the finished substrate.
