  • Patent number: 11197784
    Abstract: An absorbent disposable article, such as a diaper, panty diaper, panty liner, sanitary napkin or incontinence device is disclosed. The article has a porous polymer-based structure obtainable by a process of: (a) depositing and photopolymerizing, layer-by-layer in accordance with a predetermined 3D model, an emulsion having an external continuous phase surrounding droplets of an internal phase having has one or more photopolymerizable monomers and/or oligomers and a photopolymerization initiator; and (b) removing the internal phase from the continuous polymer phase formed from the one or more photopolymerizable monomers and/or oligomers. The process produces a monolithic porous structure having three types of pores: (i) pores resulting from the location from which the internal phase was removed, (ii) pores interconnecting the pores according to (i), and (iii) pores as predetermined by the 3D model. The invention also relates to a method of making the article.

  • Patent number: 11180272
    Abstract: A method and apparatus are disclosed for compressing an elongate stack of folded absorbent tissues to form a tissue log. A stack of folded absorbent tissues is transported along a compression path from an input end to an output end, the compression path being defined between first and second opposed transport surfaces provided on first and second compression members. The first compression member is moved towards the second compression member from a first spacing to a second spacing to compress the stack and form the log. The compression path has a length greater than the stack length and during compression, the stack moves along the compression path with respect to the compression members. During this process, the stack will be compressed from a first height to a second height corresponding to the second spacing.
