Abstract:
A fiber made from an ethylene polymer composition, wherein the composition comprises(A) from about 10 percent (by weight of the total composition) to about 95 percent (by weight of the total composition) of at least one homogeneously branched linear ethylene/.alpha.-olefin interpolymer having:(i) a density from about 0.89 grams/cubic centimeter (g/cm.sup.3) to about 0.935 g/cm.sup.3,(ii) a molecular weight distribution (M.sub.w /M.sub.n) from about 1.8 to about 2.8,(iii) a melt index (I.sub.2) from about 0.001 grams/10 minutes (g/10 min.) to about 10 g/10 min.,(iv) no high density fraction,(v) a single melting peak as measured using differential scanning calorimetry, and(vi) a slope of strain hardening coefficient greater than or equal to 1.3; and(B) from about 5 percent (by weight of the total composition) to about 90 percent (by weight of the total composition) of at least one heterogeneously branched ethylene polymer having a density from about 0.93 g/cm.sup.3 to about 0.965 g/cm.sup.3.
