Modeling color alterations after the spinning process

Color represents an important element in the visual aspect of a fabric. However, during the different stages in producing a fabric (spinning, weaving, knitting...), color evolves due to different surface textures. This paper presents a preliminary approach to modeling color evolution during the spinning stage when the roving is transformed into yarn. After spinning, the yarn is not dyed, and the color depends uniquely on the initial color of the roving.
