An ethylene/alpha-olefin interpolymer suitable for use in fibers and nonwovens having a density of from 0.911 to 0.939 g/cc, a Brookfield viscosity of less than or equal to 50,000 cP, and a molecular weight distribution (Mw,cc/Mn,cc) of 1.8 to 3.5.
A meltblown nonwoven comprising an ethylene/alpha-olefin interpolymer, wherein the ethylene/alpha-olefin interpolymer has:
- a density of from 0.911 to 0.939 g/cc,
- a Brookfield viscosity of less than or equal to 50,000 cP, and
- a molecular weight distribution (Mw,cc/Mn,cc) of 1.8 to 3.5.
A composite structure having a SaMbSc configuration, wherein S is a spunbond nonwoven, M is the meltblown nonwoven of 5, and a, b, and c are the number of layers and are independent integers ranging from 1 to 5.
