Abstract

Thermally bonded fabrics having high normalized tensile strength are disclosed. Blends of high molecular weight linear ethylene polymers and low molecular weight linear ethylene polymers provide improved staple fiber-forming capabilities over that found with either polymer taken alone. Staple fibers formed from the blends have Q values above 4.5 and/or I10/I2 values above 7. The staple fibers formed from the blends of high molecular weight linear ethylene polymers and low molecular weight linear ethylene polymers have a broader thermal bonding window than either linear ethylene polymer taken alone.
At least one of the linear ethylene polymers useful for blending for forming staple fiber can be a higher alpha-olefin in the C3-C12 range, preferably in the C3-C8 range.
