Definitions
- the present invention relates to a process for the production of structured surfaces with great hydrophilicity, characterized in that the surfaces with great hydrophilicity.
- the present invention further relates to surfaces obtainable by the process according to the invention.
- Modern methods often use the Lotus Effect® to produce surfaces with a low tendency to become dirty, for example WO 96/04123 and EP-B 1 171 529.
- a Lotus effect In order to equip a surface with a Lotus effect, one can proceed, for example, in such a way that surfaces are modeled after the lotus plant with a micro-rough surface, for example with elevations and depressions in dimensions, that the distance of the elevations is in the range from 5 to 200 ⁇ m and the height of the elevations is in the range from 5 to 100 ⁇ m and at least the elevations consist of, for example, hydrophobic polymers and cannot be removed by water or water with detergents.
- a disadvantage of textile surfaces equipped with a lotus effect is, however, that they are not permeable to perspiration.
- perspiration permeability is desirable in many cases, particularly in the case of clothing. It is also desirable that diapers hold urine and do not give rise to urine drops. This applies, for example, to diapers that are manufactured using polypropylene and superabsorbents.
- Another method of making surfaces dirt-repellent is to make them very hydrophilic. Water then forms a film and easily removes dirt particles, see. for example WO 03/66710.
- the task was therefore to provide a process by which surfaces can be treated, which repel dirt and have good durability. Furthermore, there was the task of providing coated surfaces with great hydrophilicity. Finally, the task was to provide uses for coated surfaces.
- surfaces with great hydrophilicity are those surfaces which have a non-measurable contact angle with water. Water does not form droplets on the surfaces according to the invention, but spreads to form a film.
- Objects with at least one surface are used to produce structured surfaces according to the invention.
- such objects are also called substrates, which can consist of a large number of materials, for example
