This research paper primarily deals with the qualitative analysis of the yarn produced at different dyeing parameters. A normal problem of the industry is also discussed and can be effectively solved by using this study, during dyeing of fibers for mélange yarn manufacturing. It was found that the mechanical properties of cotton mélange yarn manufactured by changing the dyeing parameters greatly vary, thus it is essential to optimize it. Various qualitative parameters such as spun length, short fiber index (SFI), tenacity, elongation%, yarn evenness analysis, nep count analysis and yarn hairiness have been discussed and compared by changing both parameters of reactive dyeing i.e. dyeing time and dyeing temperature.
