<p>Acoustic panels can be readily decorated by spraying single-coloured paint thereon. It is, however, often desired, instead of this, also to provide a multi-coloured pattern, which is decorative and/or represents figures, in order also to achieve visual effects with the aid of the acoustic panel. This can be achieved in transfer printing if the application, which is necessary for this purpose, of a backing layer, which is appropriate for paint, onto the cover layer, consisting of a glass fibre mat or fabric, takes place such that said cover layer remains porous and the functioning of the acoustic panel is thus ensured. For this purpose, it is provided that the individual glass fibres are already coated with the backing layer before a cover layer is formed from them. <IMAGE></p> |
