Abstract
Highly coherent and rigid synthetic multifilamentary yarn of improved functional properties having a novel and unique configuration composed of multiple, retained, successive and alternate twist regions is manufactured by twisting thermoplastic fibers by a false-twisting means and at a high temperature selected with reference to the combined properties of the degree of the double refraction and the density of the material fiber.
