Embodiment Construction

[0026] As used herein, the term "bicomponent fiber" refers to a fiber of at least two different polymers extruded from separate extruders but spun together to form one fiber. Bicomponent fibers are also sometimes referred to as conjugate fibers or multicomponent fibers. The polymers are arranged in distinct regions of substantially constant positioning across the cross-section of the bicomponent fiber and extend continuously along the length of the bicomponent fiber. For example, the configuration of such bicomponent fibers may be a sheath / core arrangement in which one polymer is surrounded by another polymer, or may be a side-by-side arrangement, a pie arrangement, or an "islands-in-the-sea" arrangement.

[0027] As used herein, the term "bicomponent fiber" refers to a fiber formed from at least two polymers extruded from the same extruder as a blend. Biconstituent fibers do not have the various polymer components arranged in relatively constantly positioned distinct zones i...

Abstract

The invention discloses a heterogeneous mass. The heterogeneous mass comprising a longitudinal axis, a lateral axis, a vertical axis, one or more enrobeable elements and one or more discrete open cell foam pieces is disclosed. The open cell foam pieces comprise pores and vacuoles.

Description

technical field [0001] The present invention relates to absorbent structures useful in absorbent articles such as diapers, incontinence briefs, training pants, diaper retainers and liners, sanitary garments and the like. In particular, the present invention relates to an absorbent structure utilizing discrete foam blocks having cavities. Background technique [0002] Open cell foams are used for their absorbent properties. Open cell foams include latex polymer foams, polyurethane foams, and foams produced by polymerizing emulsions. One type of open-cell foam is produced from an emulsion, which is a dispersion of one liquid in another liquid and generally takes the form of a water-in-oil mixture in which the aqueous phase is or is dispersed in a substantially insoluble Miscible continuous oil phase. Water-in-oil (or oil-in-water) emulsions having a high ratio of dispersed phase to continuous phase are known in the art as high internal phase emulsions, also known as "HIPE" ...
