Abstract

La présente invention concerne un procédé de fabrication d'un matériau décoratif comprenant : S1) l'application d'un revêtement de polyuréthane sur la surface d'un substrat pour obtenir un substrat revêtu d'un revêtement ; et S2) la réalisation d'un gaufrage sur le substrat revêtu d'un revêtement pour obtenir un matériau décoratif, une couche de motif non caractéristique d'un rouleau de gaufrage utilisé pour le gaufrage présentant une rugosité de 1,5-2,5 µm et un brillant de 5-18. La rugosité et le brillant de la surface d'un matériau décoratif sont ajustés au moyen d'un gaufrage pour réguler le coefficient de frottement de la surface du matériau décoratif, et par conséquent, la sensation tactile de surface du matériau décoratif est améliorée de sorte que le matériau décoratif présente une sensation de toucher soyeux.
