Definitions

  • the innovation concerns a multi-washable and reusable diaper with a disposable layer for excrement for babies, children and adults consisting, apart from the disposable layer, of a unit that has a liquid-tight outer layer, a liquid-permeable cover on the inside, and an absorbent element arranged in between , as well as incorporated elastic-stretchable bands and a width-adjustable closure system by welding and / or sewing together.
  • diaper pants usually consist of a liquid-permeable cover made of non-woven material, a liquid-tight outer layer made of a thin polyethylene film and a suction pad arranged therebetween consisting essentially of cellulose fibers with incorporated polyacrylates for urine binding.

  • the washable diaper pants reduce the environmental impact and the volume of the mill, but due to the use of cotton and natural fibers in the absorbent core and inner cover, because of their low absorption potential, the aggressive urine comes into permanent contact with the skin of the user. This leads to drenching of the clothes and inflammation as well as irritation of the skin.
  • the object of the invention is to create a washable, reusable diaper which has a large storage volume of liquid and does not or only slightly return the liquid to the skin of the user due to moisture protection, and leakage of liquid on the leg. and waist area almost completely prevented even under extreme loads. It should also ensure a secure, closable locking system, so that it is easy to put on and handle. In addition, the diaper should have an additional leakage protection in the absorbent area.

Furthermore, the use of the disposable layer from the carrier or auxiliary persons (in babies or children) contributes to a decisive improvement in the disposal of the coarse solids, since this disposable layer can easily be removed and disposed of for excrement.
