PROBLEM TO BE SOLVED: To provide an ultrafine fiber textured yarn not exhibiting a self-crimpable elastic function before carrying out heat treatment in dyeing and finishing, namely having excellent dimensional stability of yarn and exhibiting an elastic function capable of readily weaving. SOLUTION: A thermoplastic fiber having a self-crimpable elastic function is adopted and ultrafine fiber is false-twisted by a compressed air jet apparatus and two kinds of materials are entangled and conjugated to prepare a high-class yarn having an elastic function. Thereby, production steps of the elastic conjugate yarn are simplified and production cost is reduced and excellent dimensional stability is imparted to the yarn, because the high-class yarn having the elastic function does not exhibit the self-crimpable elastic function before carrying out heat treatment of dyeing. As a result, the yarn is readily woven and suitable for spinning industry and textile industry and clothes made of the textured yarn is comfortable, compared with clothes made of a conventional ultrafine textured yarn not having elasticity.
