With decorative papers and wallpapers, the focus is not so much on technical requirements as on appealing visual features. STW fibres are used as colouring components and as components that affect the surface structure in paper production. Natural fibres in particular set accents with their brown tones and fibre length profiles. As renewable raw materials, they also contribute to a positive CO₂ footprint. STW fibres with a large diameter produce corresponding surface structures and thus serve tactile perception.
