Zusammenfassung:	PURPOSE:To draw yarn in high ratio without damaging the surface of yarn and to obtain the subject dense yarn having high orientation by drawing wet yarn spun by dry wet type spinning method under a specific condition. CONSTITUTION:Wet yarn spun by dry wet type spinning method is sent through a feed side guide to a hot water bath and drawn in the water bath. An ultrasonic vibration is applied at least to the feed side guide and the yarn is drawn while being vibrated with ultrasonic wave and to utterly eliminate bonding between yarns in the drawing process. The drawn yarn is heated, dried and the structure is more densified by evaporation of water.
