Abstract
In fabric beam dyeing, it is difficult to apply the dye uniformly to the fabric because the fabric remains stationary while dye liquor is circulated through it. The uniformity of the liquor flow profile is critical to obtain uniform shade. This study used Computational Fluid Dynamics to determine how using metal collars and end-caps affect the liquor flow profile through the fabric during dyeing. This research found that placing the collars a distance of about 30% of the winding height under each side of the fabric gave the most uniform liquor flow profile of any collar position. In addition, the use of end-caps gave more uniform liquor flow than did the use of collars. A more uniform liquor flow profile would be expected to provide a more level dyeing.
