Abstract
The invention relates to a method for producing geotextiles with a defined adjustable isotropy, particularly of the mechanical properties in the longitudinal transverse direction.
Claims9
Method for the production of geotextiles with defined isotropy, wherein the melt-spun filaments are laid down in at least two layers, wherein the filaments in the first laydown are laid down through guide plates largely parallel next to one another and at an angle adjustable through the guide plates, and in a second laydown in the same manner, however, such that it is mirror-inverted.
