Abstract: Disclosed is a curly fiber having a fiber centroid and comprising a first region having a first centroid and a second region wherein the first region comprises an ethylene/alpha olefin interpolymer composition in an amount of at least 75 weight percent based on total weight of the first region and wherein the ethylene/alpha olefin interpolymer composition is characterized by a low temperature peak and a high temperature peak on an elution profile via improved comonomer composition distribution (ICCD) procedure, and a full width at half maximum of the high temperature peak is less than 6.0° C. and the second region is a material comprising a polymer which is different from the ethylene/alpha-olefin interpolymer of the first region and wherein the regions are arranged such that at least one of the first centroid and the second centroid is not the same as the fiber centroid.

Abstract: A process comprising forming fibers having at least a first region and a second region wherein the first region comprises an ethylene/alpha olefin interpolymer composition characterized by: density in the range of 0.930 to 0.965 g/cm3; melt index (I2) in the range of from 10 to 60 g/10 minutes; molecular weight distribution in the range of from 1.5 to 2.6; tan delta at 1 radian/second of at least 45; a low temperature peak and a high temperature peak on an elution profile via improved comonomer composition distribution (ICCD) procedure; and full width at half maximum of the high temperature peak is less than 6.0° C. and stretching the fibers to an elongation of at least 20% thereby increasing curl of the fiber. The process may further include forming a non-woven from the fibers and the stretching of the fibers may occur before or after forming of the non-woven.

Abstract: The present disclosure provides for an automated spray system (100) to produce an elastomeric pad on a railroad tie. The automated spray system (100) includes a two-component spray system (102) for spraying a two-component reaction mixture to produce the elastomeric pad on the railroad tie. The automated spray system further includes a gantry system (140) having girder (146) that supports the spray applicator.

Abstract: The present invention provides multi-layer articles for use as a rail tie footings comprising, as the tie, an elongate rigid body having a substantially planar surface, and on the substantially planar surface comprising a a microcellular foam elastomeric pad, for example, of a substantially organic solvent free polyurethane, wherein the substantially planar surface has a peripheral landing on which there is no elastomeric pad and the elastomeric pad has a bulk density (ASTM D3676) of from 600 to 2000 Kg/m3 (0.6 to 2.0 g/cm3). In addition, the present invention provides molding methods wherein the microcellular foam elastomeric pad is molded directly on the rail tie to form a durable footing, wherein the rail tie forms the bottom boundary of a molding chamber during molding and molding comprises forming the top and side boundaries of the molding chamber by inflating an annular pneumatic seal, positioning the seal on the substantially planar surface of the elongate rigid body and keeping the microcellular foam forming materials under pressure during molding.
