Abstract: 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. In various embodiments of the invention, the elasticity is improved by preparation techniques that enhance the ratio of elastic fiber: cellulose fiber bonding versus cellulose fiber: cellulose fiber bonding. These techniques include wet and dry high intensity agitation of the elastic fibers prior to mixing with the cellulose fibers, deactivation of the hydrogen bonding between cellulose fibers, and grafting the elastic fiber with a polar group containing compound, e.g. maleic anhydride.

Abstract: The subject invention provides a polymer mixture having high heat resistivity, low hexane-extractive and controllably lower or higher modulus. The mixture is comprised of at least one first substantially linear ethylene polymer, Component (A), and at least one second ethylene polymer which is a homogeneously branched polymer, heterogeneously branched linear polymer or a non-high density. When fabricated into film, the mixture is characterized by a heat seal initiation temperature which is substantially lower than its vicat softening point as well as a high ultimate hot tack strength. When fabricated as a molded article, the mixture is characterized by high microwave warp distortion while maintaining a lower modulus. The polymer mixture is particularly well-suited for use in multilayer film structures as a sealant layer for such applications as cook-in packages, hot-fill packages, and barrier shrink films. In molding applications, the mixture is well-suited as freezer-to-microwave food storage containers and lids which maintain good flexibility at low temperature to allow easy openability of such containers.
