What differentiates textiles from most other media is their strong surface texture. The incident angle of the illumination can have a strong effect on the reading. For example, 45° illumination creates shadow areas behind each raised fiber which will be "seen" by a 0° sensor.
Which may be a good reason NOT to use the ColorMunki for the task. Unlike the i1Pro which illuminates from all sides, it only illuminates from one direction.
Diffuse illumination may be useful to alleviate that problem.
i.e. a sphere geometry instrument. But I think that almost all of them are spot measuring, so you would need an automated table to measure lots of patches. Maybe a Spectroscan with polarization filter fitted ? Graeme Gill.
