Definitions

  • the invention relates to an absorbent article suitable for collecting and retaining loose faeces
  • Absorbent articles are commonly used for the absorption of bodily exudate such as urine, faeces, blood and sweat Efforts have been made in recent years to improve the leakage-security of such articles
  • Loose faeces are those which have a higher liquid content than the average human faeces Loose faeces can for example be produced by breastfed infants, or by individuals with diarrhoea Loose faeces can cause absorbent articles to leak, as such faeces are often highly fluid and expelled rapidly from the human body Leakage is especially a problem around the leg region of absorbent articles
