Abstract

Polymeric structures, methods for making same, fibrous structures comprising same and fibrous product incorporating same are provided.

Claims (7)

1. A fibrous structure comprising two or more fibers at least one of which comprises a polymeric structure in fiber form, wherein the fibrous structure comprises a first region comprising associated fibers and a second region comprising non-associated fibers.
2. The fibrous structure according to claim 1 wherein the fibrous structure comprises two or more regions that exhibit different values of a common intensive property relative to each other.
3. The fibrous structure according to claim 2 wherein the common intensive property is selected from the group consisting of: density, basis weight, caliper, substrate thickness, elevation, opacity, crepe frequency and mixtures thereof.
4. A fibrous product comprising one or more fibrous structures according to claim 1.
5. The fibrous product according to claim 4 wherein the fibrous product exhibits a wet lint score of less than about 25 and/or a wet pill area of less than about 4%.
6. The fibrous product according to claim 4 wherein fibrous product exhibits a dry lint score of less than about 50 and/or a dry pill area of less than about 5%.
7. A method for making a fibrous structure, the method comprising the steps of:
b. providing a fibrous structure comprising two or more fibers at least one of which comprises a polymer structure in fiber form; and b. associating two or more fibers to each other such that a fibrous structure comprising a first region comprising associated fibers and a second region comprising non-associated fibers is formed.
