摘要： A functional composite fiber and preparation thereof, and a spinneret for preparing the same. The functional composite fiber comprises a plurality of the T-lobes connected with each other at their bases, wherein the caps of the T-lobes contain a component, and their bases T-lobes contain the component and an additive. The additive is not exposed on the surface of the fiber thereby preventing post-manufacturing abrasion of the spinning machine.

摘要： 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.

摘要： A non-woven web formed from substantially continuous and uninterrupted multi-component filaments in which the filaments are spun at a spinning speed adequate for molecularly orienting less than all of the various constituent polymers. After collection, the non-woven web is either heated or receives a tensile force that causes each filament region formed from the polymer lacking molecular orientation to shrink in length considerably more than other filament regions formed from molecularly-oriented polymers. The differential length reduction enhances the loft of the non-woven web.
