Abstract
A fluid liquid acquisition/transfer layer in an absorbent article, such as a diaper, pant diaper, incontinence guard, sanitary napkin, panty liner or the like. The fluid acquisition/transfer layer includes a mixture of heat-shrunk, spiralized, thermoplastic multicomponent, preferably bicomponent, functional fibers of 3.4 dtex or more. The components of the functional fibers each have different shrinkage properties and are located in a side-by-side relationship for creating the spiralized shape of the functional fibers. The fluid acquisition/transfer layer also includes bonding fibers that bond to each other through heat treatment while the functional fibers do not bond to each other during heat treatment.
Claims20
A fluid acquisition/transfer layer in an absorbent article, said acquisition/transfer layer comprising:
- a mixture of heat-shrunk, spiralized, thermoplastic multicomponent functional fibers of 3.4 dtex or more, wherein components of said multicomponent functional fibers have mutually different shrinkage properties and are located in a side-by-side relationship;
- and
- thermoplastic bonding fibers bonded together by heat treatment, while said functional fibers are substantially unaffected by said heat treatment.
An absorbent article comprising:
- a liquid pervious topsheet;
- a liquid impervious backsheet;
- an absorbent core;
- and
- a fluid acquisition/transfer layer arranged between the topsheet and the absorbent core, wherein said fluid acquisition/transfer layer comprises:
- a mixture of heat-shrunk, spiralized, thermoplastic multicomponent functional fibers of 3.4 dtex or more, wherein components of said multicomponent functional fibers have mutually different shrinkage properties and are located in a side-by-side relationship;
- and
- thermoplastic bonding fibers bonded together by heat treatment, while said functional fibers are substantially unaffected by said heat treatment.
