Abstract
A polymer blend is provided, which includes 100 parts by weight of a first polyolefin, 3 to 100 parts by weight of a thermoplastic polyurethane, and 3 to 10 parts by weight of a modified polyolefin. The modified polyolefin is formed by grafting maleic anhydride or acrylate onto a second polyolefin. The blend can be used to form fiber.
