Publication number: 20050061456Abstract: The elasticity of elastic, absorbent structures, e.g., diapers, is improved without a significant compromise of the absorbency of the structure by the use of bicomponent and/or biconstituent elastic fibers. The absorbent structures typically comprise a staple fiber, e.g., cellulose fibers, and a bicomponent and/or a biconstituent elastic. The bicomponent fiber typically has a core/sheath construction. The core comprises an elastic thermoplastic elastomer, preferably a TPU, and the sheath comprises a homogeneously branched polyolefin, preferably a homogeneously branched substantially linear ethylene polymer.
