Patent ID: 8076417

Claim:
A crosslinked elastic fiber characterized in that the fiber has been made from a composition comprising a polyolefin blend having an overall melt index (I 2 ) of less than 2.5 g/10 min before crosslinking with a density in the range of 0.865 to 0.885 g/cm 3 wherein the polyolefin blend comprises at least a first polyolefin component and a second polyolefin component, wherein the first component and second component can be classified according to the following characteristics: characteristic (a) is having a density in the range of from 0.855 to 0.88 g/cm 3 ; characteristic (b) is having a residual crystallinity at 80° C. of greater than 9%; and wherein the first component meets either characteristic (a) or characteristic (b) but not both, and the second component meets at least whichever characteristic (a) or (b) the first component does not meet.
