Abstract
Fibrous structures having improved surface smoothness, good wet feel, and are cold water soluble.
Claims26
A fibrous structure comprising a first web material and a surface comprising a surface material different from the first web material, wherein the surface material comprises a blended PVOH fiber composition comprising:
- a blend of a first PVOH having a level of hydrolysis between about 70% to about 90% and a second PVOH having a level of hydrolysis between about 92% to about 99%;
- wherein the amount of the first PVOH is between about 35% to 75% and the amount of the second PVOH is between about 25% to about 65%, based on the weight of the blended PVOH fiber composition;
- wherein the blended PVOH fiber composition has a crystallinity of less than 40% and a level of hydrolysis of at least 90%;
- and
- wherein the blended PVOH fiber composition is cold water soluble.

A blended PVOH fiber composition comprising:
- a blend of a first PVOH having a level of hydrolysis between about 70% to about 90% and a second PVOH having a level of hydrolysis between about 92% to about 99%;
- wherein the amount of the first PVOH is between about 35% to 75% and the amount of the second PVOH is between about 25% to about 65%, based on the weight of the blended PVOH fiber composition;
- wherein the blended PVOH fiber composition has a crystallinity of less than 40% and a level of hydrolysis of at least 90%;
- and
- wherein the blended PVOH fiber composition is cold water soluble.
2 more elements
A method of producing a blended PVOH fiber composition comprising:
- providing a first PVOH having a level of hydrolysis between about 70% to about 90%;
- providing a second PVOH having a level of hydrolysis between about 92% to about 99%;
- blending the first and second PVOH to produce a PVOH fiber composition;
- wherein the amount of the first PVOH is between about 35% to 75% and the amount of the second PVOH is between about 25% to about 65%, based on the weight of the blended PVOH fiber composition.
