Fibers Presence Effects on Air Flow of Attenuator of Spun-Bond Production System

Different designs of attenuator systems have been studied in this research; new analysis have been done on existed designs considering fibers effect on air flow; it was comprehended that, at fibers presence, there is an air flow which agglomerates fibers as a negative effect. So some new representations have been designed and CFD analysis has been done on them. Afterwards, one of these representations selected as the most optimum and effective design which is brought in this paper. Keywords—Attenuator, CFD, nanofiber, spun-bond.
