Foam fiber elastomeric materials and their manufacturing
The present invention concerns an elastic fibrous material, based on a fiber network, also including an elastomeric component, which material has been formed into a flat structure with two surfaces. Further, the invention concerns a method of manufacturing said elastic fibrous material by forming a fiber network, containing an elastic polymer, foaming the fiber network, adding it into one or more layers on a support, followed by curing.
Tissue comprising a softening composition
A soft tissue having a soothing feel and method of making the same is disclosed which contains an aqueous softening composition comprising from about 10 to about 20 weight percent of a cationic softening compound, such as quaternary ammonium compounds and imidazolinium compounds; from about 10 to about 20 weight percent of a polyhydroxy compound having a molecular weight of at least about 1,000 g/mol, and optionally a silicone or glycerin. Examples of the cationic softening compound include tallow- and ester-substituted quaternary ammonium compounds having chloride or methyl sulfate as the anion, and examples of the polyhydroxy compound include polyethylene glycols (PEG) or polypropylene glycols (PPG) having a molecular weight of at least about 1,000 g/mol, such as PEG-1000 and PEG-8000.
