Slub Yarn Characterisation Using Newly Developed Diametric Fault System

The work highlights the applicability of the developed Diametric Faults system for the measurements of slub yarn characteristics in industry conditions. The developed Diametric Faults system acquires the continuous and successive bi-directional view images along the length of yarn. The system measures the unevenness of yarn diameter as well as yarn diameter. The obtained values are used as threshold for identifying the region of slubs along the yarn length. The proposed system is capable to measure and analyse almost all the characteristics of the slub yarn as measured by presently available commercial systems. In addition, the system provides in-depth assessment of the length of slub portion as well as the base yarn in terms of variation in yarn slub diameter, cross-sectional area, eccentricity, and distribution of the slub length and base yarn span length.
