Abstract
This invention relates to a method and apparatus to produce space dyed yarns. A yarn sheet passes over a yarn-driven roll equipped with a digital sensor that tracks the position of the sheet as it then passes through a dyeing apparatus. A computer precisely controls the spray application of dyes at the desired locations on the length of the yarn sheet to produce space dyed POY and FOY yarns.
