Abstract
A method includes dividing a yarn into various sections with reference to the pieced yarn section, with each section being characteristic of the piecing process. A yarn profile in each section is measured and evaluated against criteria specific to each section, whereby a yarn defect and its position on the yarn are determined and from which the cause for the defect is determined. The pieced yarn section is also divided into three subsections and each subsection is measured and evaluated against certain subsection criteria for the detection of fluff, trash accumulation and fiber sloughing.
