Definitions

  • the invention relates to a decorative panel, in particular a floor panel, ceiling panel or wall panel.
  • the invention also relates to a decorative panel covering, such as a decorative floor covering, decorative ceiling covering or decorative wall covering, comprising a plurality of panels according to the invention, wherein the panels are preferably interconnected.
  • Laminated panels comprise a core layer onto which a decorative top structure is applied having a printed decorative image which typically has the appearance of a wood pattern.
  • the decorative image is covered by a transparent layer to preserve and protect said the image.
  • impressions can be realized in the transparent layer, this in order to obtain an e.g., imitation of wood pores and other unevennesses which can be present at the surface of real wood.
  • PVC is used as main constituent for composing the core.
  • the decorative image is digitally printed onto a PVC film, wherein said printed PVC film is affixed to said core.
  • the intermediate layer is a non-human collagen based layer.
  • Skin, or animal hide is formed primarily of collagen, a fibrous protein, and serves as source for composed at least a part of said intermediate layer.
  • Collagen is a generic term for a family of at least 28 distinct collagen types; animal skin is typically type I collagen, although other types of collagen may be used in forming leather.
  • Collagens are characterized by repeating triplets of amino acids, -(Gly-X-Y) n -, so that approximately one-third of the amino acid residues are in collagen are glycine.
  • X is typically proline and Y is typically hydroxyproline.
  • the structure of collagen may consist of twined triple units of peptide chains of differing lengths.
  • Collagen fiber monomers may be produced from alpha-chains of about 1050 amino acids long, so that the triple helix takes the form of a rod of about 300 nm long, with a diameter of 1.5 nm. Triple helices can be bound together in bundles called fibrils, and fibril bundles come together to create fibers. Fibers typically divide and join with each other throughout an animal skin layer. Variations of the crosslinking or linking may provide strength to the material. Fibers may have a range of diameters depending on the type of animal hide.
  • non-human collagen, and (bonded) leather in particular, is not only technically driven, but also environmentally and morally driven.
  • the global leather industry slaughters more than a billion animals per year.
  • the leather skin resulting from this slaughtering process is often and largely treated as waste, which is typically burned afterwards.
  • By reusing this leather at least partially the amount of waste is reduced and a more circular production cycle can be realised.
  • these leather residues, typically offered as bonded leather is relatively inexpensive, and therefore more attractive than other natural materials, such as cork, which may be used for this purpose.
  • the presence of one or more intermediate layer provides the panel improved acoustic dampening properties. Since at least the edges of at least one intermediate layer are typically exposing to the surrounding atmosphere, it is additionally favourable that the intermediate layer(s) has/have a relatively good resistance against cleaning agents. Due to the above properties it can be advantageous that (i) at least one intermediate layer is situated in between the core and the decorative top structure, and preferably affixed, either directly or indirectly, to the upper side of the core, and/or that (ii) at least one intermediate layer is embedded in the core, and/or that (iii) at least one intermediate layer is affixed, either directly or indirectly, to the lower side of the core.
  • the non-human collagen present in the intermediate layer is preferably derived from cows, water buffaloes, horses, deers, crocodiles, or goats, as the tear strength of this leather types are relatively high, in particular higher than 60 N/mm.
  • the intermediate layer(s) preferably comprise(s) bovine leather, which is typically preferred over ovine leather, also because there is a correlation between leather strength and fibril diameter in bovine leather.
  • bovine leather the collagen fibrils are more aligned than in ovine skin, and it was found that where tissue contains highly aligned fibrils, the fibril diameter becomes a significant determinant of strength. In tissues where the fibrils are not well aligned, the influence of fibril alignment on strength is greater than that of fibril diameter. Therefore, in leather and skin, larger fibrils may lead to stronger material, but for weaker leathers, fibril diameter is secondary to fibril alignment for strength.
  • the fibril length is at least 66 nm, which is typical for cows and horses.
  • the amount of (genuine) leather is preferably situated between 40 and 80% and more preferably approximately 60% by weight of the intermediate layer.
  • the intermediate layer is entirely (100%) composed of leather, this will commonly be considered as a rather expensive solution compared to a composite material which comprises further to leather also one or more other materials.
  • the carrier layer may be either a woven or non-woven layer.
  • the binding material is partially penetrated into the carrier layer. It is conceivable that the binding material is partially penetrated into the core and/or at least one other adjacent layer. Since the collagen of the intermediate layer typically has a porous structure, it typically allows penetration of other materials. It is therefore imaginable that the decorative top structure is partially penetrated into at least one intermediate layer situated in between the top structure and the core. More in particular, it is imaginable that a primer layer of the top structure, is partially penetrated into at least one intermediate layer situated in between the top structure and the core. Penetration of layers into each other typically increases the bonding strength between said layers.
  • At least one intermediate layer comprises between 40-80%, more preferably at least 50% and/or less than 70%, most preferably approximately 60% (+/-3%), by weight of natural leather fibres.
  • at least one intermediate layer comprises between 10-40%, more preferably at least 15% and/or less than 35%, and most preferably approximately 20% (+/- 3%), by weight of synthetic polymer and/or natural polymer, in particular natural latex.
  • at least one intermediate layer comprises between 1-20%, more preferably at least 5% and/or less than 15%, and most preferably approximately 10% (+/- 3%), by weight of fat, in particular natural fat.
  • At least one intermediate layer comprises at least one natural fat, such as fatty tissue derived from animals and/or vegetable oil, in particular rapeseed oil, wherein the amount of natural fat is preferably situated between 5 and 25%, and more preferably approximately 10% by weight of the intermediate layer.
  • a natural fat such as natural oil, in particular rapeseed oil, acts as lubricant within the intermediate layer. The presence of one or more lubricants modulates or controls fibril-fibril bonding during dehydration to leather which improves the strength of the intermediate layer.
  • Suitable lubricants include surfactants, anionic surfactants, cationic surfactants, cationic polymeric surfactants, anionic polymeric surfactants, amphiphilic polymers, fatty acids, modified fatty acids, non-ionic hydrophilic polymers, non-ionic hydrophobic polymers, poly acrylic acids, poly methacrylic, acrylics, natural rubbers, amphiphilic anionic polymer and copolymers, amphiphilic cationic polymer and copolymers and mixtures thereof as well as emulsions or suspensions of these in water, alcohol, ketones, and other solvents.
  • a polymeric substance is used as lubricant, preferably a natural (bio)polymeric substance is used.
  • At least one intermediate layer comprises at least one additive, such as, preferably vegetable, tanning agent and/or water, wherein the amount of additive is preferably situated between 5 and 20 % and more preferably 10% by weight of the intermediate layer.
  • vegetable tanning agents are pyrogallol- or pyrocatechin-based tannins, such as valonea, mimosa, ten, tara, oak, pinewood, sumach, quebracho and chestnut tannins;
  • chromium tanning agents include chromium salts like chromium sulphate;
  • aldehyde tanning agents include glutaraldehyde and oxazolidine compounds, syntans include aromatic polymers, polyacrylates, polymethacrylates, copolymers of maleic anhydride and styrene, condensation products of formaldehyde with melamine or dicyandiamide, lignin and natural flours.
  • the intermediate layer(s) may comprise at least one filler, preferably an inorganic filler, such and calcium carbonate and/or clays. These fillers may fill the interstitial spaces in loose leathers and in between leather particles, and make the looseness less pronounced, and hence the intermediate as such more robust.
  • At least one intermediate layer comprises synthetic particles, in particular synthetic fibres, in particular polymer fibres.
  • synthetic particles may e.g. be formed by glass particles, carbon particles, silicon particles or other types of polymer fibres.
  • the density of at least one intermediate layer is between 0.75 and 0.95 g/cm 3 , preferably between 0.8 and 0.9 g/cm 3 , more preferably approximately 0.85 (+/- 0.02) g/cm 3 .
  • the density is preferably measured by using ISO 2420.
  • the thickness of at least one intermediate layer is between 0.75 and 0.95 mm, preferably between 0.77 and 0.87 mm, more preferably approximately 0.80 (+/- 0.02) mm.
