Abstract

The subject of the present invention is a nonwoven based on polymers derived from lactic acid, the process for the production of and the use of such a nonwoven. Nonwoven consisting of filaments of a polymer material, characterised in that all the filaments composing it are made entirely from a polymer or from a polymer mixture derived from lactic acid.
