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/cm 3 ; 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.
