Abstract
Novel self-crimping fibers and methods for their preparation. Embodiments are provided in which fibers are melt-spun from a non-elastomeric polyamide and a thermoplastic elastomer selected from the group consisting of a polyether block polyamide copolymer and a polycaprolactone polyester. The fibers may be knit or woven into textile articles including, inter alia, hosiery, pantyhose and stockings.
