Abstract
Nonwoven (and film) topsheet and acquisition/distribution materials treated with a hydrophilic, synthetic surfactant-free finish, absorbent articles for infant or incontinence care that contain these materials, and methods for apply such finishes and/or making such absorbent articles.
Claims16
A hydrophilic, synthetic sheet comprising:
- a sheet of synthetic material having a first surface;
- where the sheet comprises a hydrophilic finish including molecules of a water-soluble proteins dispersed on the first surface;
- where the finish includes substantially no synthetic surfactants;
- and
- where a 0.5-15% aqueous solution of the water-soluble protein has a surface tension of less than 49 milliNewtons per meter (mN/m).
2 more elements
A method of imparting hydrophilic properties to a sheet of polymeric material, the method comprising:
- applying a 0.5-15% aqueous solution of the water-soluble protein having a surface tension of less than 49 milliNewtons per meter (mN/m) to a sheet of polymeric material in an aqueous solution;
- and
- drying the sheet such that at least a portion of the protein is retained on a surface of the sheet;
- where the aqueous solution is substantially free of synthetic surfactants.
