IMPROVED FIBERS FOR POLYETHYLENE NONWOVEN FABRIC

A fiber having a diameter in a range of from 0.1 to 50 denier, said fiber comprising a polymer blend, wherein the polymer blend comprises: a. from 26 weight percent to 80 weight percent (by weight of the polymer blend) of a first polymer which is a homogeneous ethylene/±-olefin interpolymer having:...

Summary:A fiber having a diameter in a range of from 0.1 to 50 denier, said fiber comprising a polymer blend, wherein the polymer blend comprises: a. from 26 weight percent to 80 weight percent (by weight of the polymer blend) of a first polymer which is a homogeneous ethylene/±-olefin interpolymer having: i. a melt index of from 1 to 1000 grams/10 minutes, and ii. a density of from 0.870 to 0.950 grams/centimeter 3 , and b. from 74 to 20 percent by weight of a second polymer which is an ethylene homopolymer or an ethylene/±-olefin interpolymer having: i. a melt index of from 1 to 1000 grams/10 minutes, and preferably ii. a density which is at least 0.01 grams/centimeter 3 greater than the density of the first polymer wherein the overall melt index for the polymer blend is greater than 18 g/10min.
