چکیده    Single yarns are plied to improve some of the yarn and fabric properties such as hairiness,strength,elongation,evenness and abrasion resistance. present work proposed a new method for the reduction of the plied yarn hairiness. the modified plying method employs an air nozzle and compressed air on a classical twisting machine. the air was fed into an air nozzle and single yarns were passed into the air nozzle. in the work,single yarns having s- and z-twist direction were plied with classical and modified plying methods at different ply twist levels and airflow properties. the results indicated that presented method may open a new avenue to achieve an extra reduction in yarn hairiness and also an increase in productivity during the plying process. in literature,there were not any trials to incorporate the air nozzle and plying process in this manner. therefore,modified method can be considered as an innovative plying process regarding with the improvement in yarn hairiness.
