Real-Time Quality Assessment of Neppy Mélange Yarn Manufacturing Using Macropixel Analysis

The aim of this paper is to provide a simple MATLAB-based model to determine the real-time homogeneity of neppy mélange yarn fabrics. Currently, the mélange yarn industry relies solely on visual assessment and experience. This algorithm, however, proposes a solution for the mélange yarn industry. The designed algorithm presented in this paper, which is based on kernel density function and macropixel analysis, was implemented for the real-time nep detection of neppy mélange yarns and calculated an inhomogeneity of neps of around 91%. This strategy would be useful for the mélange yarn industry and can also be used in other types of fashion yarns.
