Abstract
In a drawing false-twisting method, which draws a twisted yarn, heat-sets the drawn and twisted yarn, cools the yarn by making the yarn travel in contact with the surface of the guide groove of a cooling plate and untwists the yarn to obtain a textured bulk yarn, the yarn is moved laterally to spread the oil transferred from the yarn to the surface of the guide groove.
