What is claimed is: 1. A disposable absorbent article for personal hygiene, said article having a wearer-facing surface and a garment-facing surface, said garment-facing surface comprising at least one adhesive A for attachment of said article to a garment of a wearer, wherein said adhesive A on said garment-facing surface provides a first peel force of at least 0.6 N per 5 cm when measured from a microfibre substrate comprising 95% nylon and 5% elaston and having a thickness of 0.7 mm and a basis weight of 160 g/m2 according to the Peel Force on Standard Microfibre Material test method. 2. The absorbent article of claim 1, wherein said garment-facing surface is covered by said adhesive A at a surface coverage of at least 30%. 3. The absorbent article of claim 1, wherein said garment-facing surface is covered by said adhesive A at a surface coverage of at from about 70% to about 100%. 4. The absorbent article of claim 1, wherein said adhesive A is present on said garment-facing surface at a basis weight of from about 1 to about 35 g/m2. 5. The absorbent article of claim 4, wherein said adhesive A is present on said garment-facing surface at a basis weight of from about 10 to about 30 g/m2. 6. The absorbent article of claim 1, wherein said adhesive A provides a first peel force of at least 0.8 N per 5 cm when measured from a microfibre substrate comprising 95% nylon and 5% elaston and having a thickness of 0.7 mm and a basis weight of 160 g/m2 according to the Peel Force on Standard Microfibre Material test method. 7. The absorbent article of claim 6, wherein said adhesive A provides a first peel force of at least 1.2 N per 5 cm when measured from a microfibre substrate comprising 95% nylon and 5% elaston and having a thickness of 0.7 mm and a basis weight of 160 g/m2 according to the Peel Force on Standard Microfibre Material test method. 8. The absorbent article of claim 1, wherein said adhesive A provides a second peel force when measured according to the Peel Force on Standard Cotton Material test method, wherein said second peel force is up to five times higher than said first peel force, when the basis weight of the cotton material tested and the basis weight of the microfibre material tested are the same. 9. The absorbent article of claim 8, wherein said adhesive A provides a second peel force when measured according to the Peel Force on Standard Cotton Material test method, wherein said second peel force is up to three times higher than said first peel force, when the basis weight of the cotton material tested and the basis weight of the microfibre material tested are the same. 10. An absorbent article for personal hygiene, said article having a wearer-facing surface and a garment-facing surface, said garment-facing surface comprising: a) at least one adhesive A for attachment of said article to a garment of a wearer, wherein said adhesive A on said garment-facing surface provides a first peel force of at least 0.6 N per 5 cm when measured according to the Peel Force on Standard Microfibre Material test method; and b) at least one additional adhesive B, wherein said adhesive B provides a first peel force of at least 0.6 N per 5 cm when measured according to the Peel Force on Standard Cotton Material test method. 11. The absorbent article of claim 10, wherein said adhesives A and B are present on said garment-facing surface at a combined basis weight of from about 1 to about 35 g/m2. 12. The absorbent article of claim 10, wherein said adhesives A and B are present on said garment-facing surface at a combined basis weight of from preferably about 10 to about 30 g/m2. 13. The absorbent article of claim 10, wherein said adhesives A and B are present on said garment-facing surface at equal basis weight. 14. The absorbent article of claim 10, wherein said adhesives A and B are present on said garment-facing surface at a combined surface coverage of from about 70 to about 100%. 15. The absorbent article of claim 10, wherein said adhesives A and B are present on said garment-facing surface at equal surface coverage. 16. The absorbent article claim 10, wherein at least one of said adhesives A and B is a hot melt adhesive and preferably both of said adhesives A and B are hot melt adhesives. 17. The absorbent article of claim 16, wherein said adhesive A is a hot melt silicone pressure-sensitive adhesive. 18. The absorbent article of claim 17, wherein said hot melt silicone pressure-sensitive adhesive A comprises (i) a silicone resin, (ii) a silicone fluid and (iii) 1 to 10% by weight based on the total weight of the silicone resin and the silicone fluid, of at least one ester having the formula: wherein R is a monovalent hydrocarbon radical having from 2 to 32 carbon atoms, and R′ is a monovalent hydrocarbon radical having from 1 to 14 carbon atoms. 19. The article of claim 10, further comprising a backsheet, wherein said adhesive A and B are located on the garment-facing surface of the backsheet and/or on the garment-facing surface of the wings when in use.
