Abstract
An absorbent structure containing an absorbent particle size gradient is disclose. The absorbent structure may also include a fiber size gradient. The absorbent structure may also include absorbent particles coupled to loosely distributed fibers and more particularly, the absorbent particles may be electrostatically couple to the loosely distributed fibers.
Claims3
A method of making an absorbent article having a length dimension, a width dimension and a height dimension, and having a generally continuous size gradient of absorbent particles in at least one said dimension, comprising:
- a. passing a population of multiple-sized absorbent particles through a gradient forming chamber;
- b. subjecting the particles to a corona charge while within the gradient forming chamber;
- and
- c. applying the corona charged absorbing particles to a support layer in a generally continuous absorbent particle size gradient in at least one said dimension of the absorbent article.
