Abstract
A waistband for an absorbent article having a waistband with differential extensibility and/or contraction along the circumference of the waist opening. The waistband may provide a uniform appearance along the circumference of the waist opening. The waistband may have a central zone and at least two outboard zones. The outboard zones of the waistband may be less contracted than the central zone, when the absorbent article is in a relaxed state.
Claims7
A method of making the waistband, comprising:
- elongating a central portion of an elastic material;
- elongating an outboard portion of the elastic material;
- affixing the elastic material to another material with the central portion elongated and the outboard portion elongated to form a waistband component;
- allowing the central portion of the elastic material to relax, thereby creating a waistband component laminate with a contracted central portion;
- and
- applying the waistband component laminate to an absorbent article comprising:
- a rear waist portion comprising a rear waistband comprising a topsheet layer and a backsheet layer;
- a front waist portion opposite the rear waist portion;
- and
- a crotch portion longitudinally connecting the rear waist portion and the front waist portion;
- wherein the waistband component laminate is applied to the rear waist portion so that gathers are formed in the topsheet layer and/or the backsheet layer within the rear waist portion;
- wherein an applied percent elongation of the central portion is greater than that of the outboard portion.
