ABSORBENT STRUCTURE WITH IMPROVED WATER-ABSORBING MATERIAL

摘要

The present invention relates to an absorbent structure suitable in, or being an adult or infant diaper or feminine hygiene article, comprising a water-absorbing material comprising water-absorbing particles that comprise a film coating, comprising an elastic film-forming polymer and an antioxidant. The invention also relates to an absorbent structure comprising a water absorbent material obtainable by a process of: a) spray-coating water-absorbing polymeric particles with an elastic film-forming polymer in a fluidized bed reactor at a temperature in the range from 0°C to 150°C and b) heat-treatment of the coated polymeric particles at a temperature above 50°C, wherein in step a) and/or b) an antioxidant is added.
