  • At least one of the outer surface areas for example made of cotton, has a profiling or creasing or a different surface structure, for example by bombarding a corresponding one Cotton layer can be generated with water jets or is achieved by other suitable technological measures.
  • the product according to the invention can also have at least one outer surface area which consists at least partially of synthetic fibers. Particularly favorable properties can be achieved if this outer surface area consists at least partially of a fleece, in particular polyester fleece.

  • a method for producing products according to the invention with an outer surface area consisting of cotton fibers is explained below by way of example. Cotton is used as raw material in the form of fiber bales for the manufacture of the product.

Furthermore, in some cases it is sufficient if only one of the layers is consolidated, and the consolidation and / or structuring can also be achieved with other measures, such as with a roller press or the like. Finally, the mass per unit area of the individual nonwovens can vary, whereby the range of variation for each fleece can reach 50% or more of the stated values. Particularly good results are achieved if the range of variation is less than 20%, in particular less than 10%, with respect to the stated values.
