Sažetak
Colour values of woven structure depend on colour of warp and weft threads and constructional parameters. Beside colour, constructional parameters influence also on cover factor of woven fabric. Both size and disposition of spaces between threads, in consequence, influence not only on air and light permeability and fabric's tightness but also on colour of woven fabric's surface. The aim of the research is to analyse the influence of foundation reflectance and its colour on colour values of woven structure. In this purpose, three groups of woven fabrics were woven on the loom, taking into account three different warp densities and five different weft densities in each group. Colour of warp threads differed from the colour of weft threads, but both were constant in all fabrics. The measurements of colour values of woven structures by three different foundations were carried out with spectrophotometer. The colours of foundation were: white, black and colour of analysed woven fabrics. The constructional parameters of fabrics and threads (thread fineness, density, weave) were used in order to design simulations with CAD system Arahne. Colour values of woven fabrics and simulations were, furthermore, also theoretically calculated. Finally, colour differences between calculated and measured colour values of real woven fabrics and simulations and colour differences between fabrics with different foundations were analysed. The results numerically present the influence of foundation and its colour no colour values of both real woven fabrics and simulations by changing constructional parameters of woven fabrics. Moreover, colour values of woven structures and simulations can be theoretically predicted, but only if the influence of foundation reflectance with its dimensions and colour values is considered.
