This study is mainly directed towards blends of cotton and polyester which are cotton-rich blends. Measurements taken from dyed tracer fibers within the yarn and from physical testing indicate that only yarn count significantly affects several of the migration parameters. Coarser or lower count yarns exhibit slower rates of migration as measured by the mean migration intensity, and also showed a reduced tendency towards migration as measured by the root-mean-square deviation. Yarn count was the most significant parameter affecting yarn quality. Fiber fineness significantly affected thick places, break factors, single-end strengths and elongations. Polyester staple length significantly affected evenness and imperfections. Blend level significantly affected thick places, elongations, neps, and break factors.
