Abstract

Whiteness of textiles is one of the main "white" product quality indicators described by the following parameters: lightness of a colour, colour tone (white shade), white uniformity and stability under the influence of physical factors. “White” textile products can be perceived by comparing them with a white standard (Pantone colour palette). On the other hand, the whiteness of the fabric can be estimated using the colorimeter and determining lightness of a fabric L. The purpose of a research is to assess the whiteness of a linen and semi-linen fabric using two different methods, to carry out a comparative analysis of the results and to associate fabric whiteness with the fabric structure parameters. Two methods were used for experiment (colorimeter Spectraflash SF450X and expert assessment of whiteness). The analysed colours of a fabric were divided into five colours: white, whitish, light grey, grey and dark grey. The examination of the two methods, different results were obtained: testing with colorimeter, white colour was found in only one fabric, while the experts found the fabrics of white colour much more. The opinions of experts vary also. Fabric lightness L was associated with fabric structure parameters – the warp and weft settings and fabric weave. It was found that these fabric structure parameters affect the lightness of a colour of a fabric L very little.
