Abstract
A method and apparatus for producing an air textured yarn is disclosed, and wherein a partially oriented and fully drawn yarn is withdrawn from a supply package, wrapped about a heated godet, and then directly advanced into an air texturing nozzle. In the nozzle, a jet of unheated air serves to impart loops, curls, bows and the like to the advancing yarn. The yarn is advanced from the heated godet to the air jet nozzle under a relatively low tension so as to permit the heated yarn to shrink and thereby reduce the residual shrinkage. The jet of unheated air in the air jet nozzle also cools the yarn and thus the formation of the loops, etc. occurs only after shrinkage has ceased.
