| Summary: | Colour matching between carded and finished fibres is an important
challenge for textile industry. The straightforward approach for
mixing together some differently coloured fibres in order to
obtain a blend of a desired colour is to perform a trial and error
approach starting from a given colour recipe and optimizing it
with several attempts. Unfortunately, dyeing process so as the
carding procedure may result in a carded fibre whose colour is
different from the desired one. As a consequence textile companies
have to modify the original recipe in order to reduce the gap
between the colour of the final product and the desired one. The
present work describes a model able to simulate the colour mixing
of fibres in order to assess the best recipe. The model consists
in two modules: a “prediction module” predicts the colour of a
blend obtained by mixing together several fibres; an “optimization
module” is used to optimize the final recipe. The devised system
has been tested for optimizing the recipe of a set of 200 blends.
The mean error in predicting the blend colour is about 15% with a
variance of 0.165. The time for optimizing the recipe is reduced
by 92%. |
