- This peer-reviewed research paper, accepted for publication by Coloration Technology, addresses key research questions relating to the development of a commercially viable blending system for pre-coloured fibre blends. This includes determining the maximum colour difference between blend components, the effect of composition on blend appearance (loose stock fibre, yarn, knitted) and the number of colours (primaries) required to cover a given area of colour space.
To date, the blending of multiple primaries has predominately related to the intentional creation of melange blends. The method of blending multiple primaries to create blends which appear as one colour is less understood.
In order to answer the research questions, the authors produced 4-colour fibre blends in loose stock, yarn and knitted form. The samples were assessed using controlled, psychophysical experiments, and the results used to determine the mean colour difference required between blend components (so that the sample appears visually solid at a given distance). For 50% or more of participants to view a sample as appearing as one colour, the mean colour difference (DE) of the four blended primaries was found to be 20.8DE, 20.5DE and 18DE for fibre, yarn and knitted samples respectively. Delauney triangulation was then used to map the position, and number, of primaries required within a given area of colour space. It was found that to cover a large area of colour space, with primaries spaced no more than 18 CIELAB units apart, 150 primaries were required. If a smaller gamut is required then the number of primaries is reduced.
This work is significant as the results support the development of a blending system for pre-coloured fibre blends which has economic and environmental benefits compared to conventional dyeing techniques. A relatively small number of primaries can be blended in varying proportions to create a wide range of colours.
