Abstract
A wet wipe that exhibits a novel combination of properties and methods for making such wet wipes are provided.
Claims13
A wet wipe comprising:
- a fibrous structure, wherein the fibrous structure comprises filaments and solid additives;
- and
- a liquid composition comprising a plurality of droplets suspended in water, each droplet comprising a liquid core surrounded by a solid film, each liquid core comprising a lipophilic emollient, and each solid film comprising a plurality of clay mineral particles each having a particle size of about 1 micron;
- wherein the wet wipe exhibits a Tactile Sensory Coefficient of Friction of less than 0.60 as measured according to a Tactile Sensory Coefficient of Friction Test Method;
- wherein the fibrous structure is layered;
- wherein the fibrous structure has a basis weight of from about 40 g/m2 to about 60 g/m2;
- wherein the fibrous structure has a density of less than 0.10 g/cm3;
- wherein the liquid composition is present at from about 200% to about 400% of the basis weight of the fibrous structure;
- wherein the filaments and the solid additives are present in the fibrous structure at a first weight ratio of at least 1:7;
- and
- wherein the wet wipe has a Cleaning Coefficient of Friction of greater than 0.50 as measured according to a Cleaning Coefficient of Friction Test Method.

A wet wipe comprising:
- a fibrous structure, wherein the fibrous structure comprises filaments and solid additives;
- wherein at least one of the filaments comprises a thermoplastic polymer or a natural polymer;
- and wherein the solid additives comprise a fiber;
- and wherein at least one surface of the fibrous structure comprises a layer of filaments;
- and
- a liquid composition comprising a plurality of droplets suspended in greater than 90% water, each droplet comprising a liquid core surrounded by a solid film, each liquid core comprising a lipophilic emollient, and each solid film comprising a plurality of clay mineral particles each having a particle size of about 1 micron;
- wherein the wet wipe exhibits a Wet to Dry Drape Ratio of less than about 0.80 as measured according to a Wet to Dry Drape Ratio Test Method;
- wherein the fibrous structure is layered;
- wherein the fibrous structure has a basis weight of from about 40 g/m2 to about 60 g/m2;
- wherein the fibrous structure has a density of less than 0.10 g/cm3;
- wherein the liquid composition is present at from about 200% to about 400% of the basis weight of the fibrous structure;
- wherein the filaments and the solid additives are present in the fibrous structure at a first weight ratio of at least 1:7;
- and
- wherein the wet wipe has a Cleaning Coefficient of Friction of greater than 0.50 as measured according to a Cleaning Coefficient of Friction Test Method.
