Abstract
Disclosed are films, tapes, and melt-spun fibers comprising or prepared from a composition comprising (a) at least one polyamide polymer; and (b) from about 0.1 to 20 weight % of at least one ethylene copolymer such as ethylene/vinyl acetate dipolymers, ethylene/vinyl acetate terpolymers, ethylene/alkyl (meth)acrylate dipolymers, ethylene/alkyl (meth)acrylate terpolymers, functionalized ethylene copolymers, ethylene/acid copolymers, and salts thereof. The films, tapes and fibers exhibit improved tensile properties such as tensile strength and elongation at break compared to nonmodified polyamide compositions. Also disclosed are nonwoven textiles comprising or prepared from the oriented melt-spun fibers.
