Current commercial fiber testing was not designed to measure or detect the presence of dead or immature fibers in the small quantities that has been determined to be detrimental to the quality of dyed finished products. The methodology described in this study, utilizing dyed yarn, offers a promising media for an accurate and repeatable applied test method for the quantification of white specks. It is a logical assumption that white specks appearing on the surface of dyed yarn will also appear, to a certain degree, on the surface of cloth made from this yarn. A tool, based on dyed yarn will be a proactive approach of quantifying white specks that can be tailored to a yarn spinner, knitter, and dyer’s specific end use.
