Researchers investigated methods of determining final fabric color based on the color of fabric while still wet from the continuous dyeing process. To predict the 'dry' color based on a fabric's 'wet' color, a substrate specific curve generated from the change in reflectance of a wool fabric over a full range of moisture contents was used. Scoured plain weave wool was used to create four dyed samples with various Drimarene dyes. One sample was left undyed. After treatment of the 5gram fabric samples with dye, the samples were washed off, rinsed, and immersed in distilled water before mangling to achieve even moisture content. Changes in moisture and reflectance measurements were used to produce a normalized curve representing all reflectance changes for reactive dyes on wool. Because the reflectance changes were the same for dyed and undyed samples, the color appearance changes of a fabric due to the influence of moisture are a physical phenomenon to the influence of moisture are a physical phenomenon unrelated to the dye itslef. 6 refs.
