Abstract
To wrap a hygienic fleece consisting of a cotton wool web in fluff-proof form without the need for a separate nonwoven material, synthetic fiber is added to the starting material in a quantity sufficient for thermoplastic consolidation of the surface and a surface of the prepared cotton wool web is consolidated to give a nonwoven finish. A calender comprising at least one heating embossing roller is used.
