Abstract

A fiber is obtainable from or comprises an ethylene/α-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and (1) cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re>1481−1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven or non-woven fabrics can be made from such fibers.
