ABSTRACT:
A conjugate filamentary yarn, which is prepared from composite components respectively comprising thermoplastic elastomer and non-elastomeric polyamide or polyester, and each of the individual constituents has a cross section of a compressed flat shape like a cocoon or oval, is provided. Hereby, a highly stretchable crimped elastic yarn, in which stretchability arising from crimp and rubber-like elasticity resulting from elastomer are utilized to the utmost, is made available with economy.
