Definitions
- said folded core structure is a folded core structure being produced from an uncut flat body which can be composed of a synthetic polymer, by plastic deformation perpendicular to the plane of the material such that three-dimensional structures and connection areas are formed, so that half cells and connection areas are formed, wherein the half cells are at an angle a to each other to provide a relaxed honeycomb structure or adjoin one another in the form of a honeycomb cell to provide a half-closed folded honeycomb structure.
- the connection areas are relatively small in comparison to the half cells.
- the uncut flat body preferably is a continuous film.
- the folded core structure can also be a relaxed honeycomb structure.
- This relaxed honeycomb structure is produced in the same manner as the half-closed honeycomb structure with the exception that the folding of the plastically deformed uncut flat body is stopped before the half-cell walls meet together to form the half- closed honeycomb structure.
- the half-cells of the relaxed honeycomb structure have a height h of 1 mm to 60 mm, preferably of 2 mm to 20 mm, and more preferably of 3 to 15 mm, and most preferably of 3 to 10 mm.
- the half-cells of the half-closed honeycomb structure have a height h of 1 mm to 60 mm, preferably of 1.5 mm to 20 mm, and more preferably of 1.5 to 15 mm, and most preferably of 2 to 10 mm.
- the method of determining the height of the half-cells of the half-closed honeycomb structure is also applicable to the half-cells of the relaxed honeycomb structure.
- the distance, i.e. the diameter and the height of the honeycomb cells are indicated by dashed lines in Figures 3, 5 and 6.
- the adjoining cell walls can be bonded to each other by any suitable method such as mechanical bonding, chemical bonding and/or thermal bonding.
- the adjoining cell walls are bonded chemically and/or thermally.
- the thermoplastic polymeric material of the folded core structure comprises a multi-layered laminate.
- the thermoplastic polymeric material of the multi-layered laminate is selected from a group consisting of polyolefins, in particular polyethylene (PE) or polypropylene (PP), polyesters, in particular polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT) or polyetylene-1 ,2- furandicaboxylate (PEF), polyamides, in particular polyamide 6 (PA6) or polyamide 6,6 (PA6,6), polyetherketones (PEK), polyetheretherketones (PEEK), polyetherketoneketones (PEKK), polyvinyl butyral (PVB), polycarbonate (PC), polyether, polyetheresters, copolymers and blends thereof.

- PTT polytrimethylene terephthalate

- the folded core structure comprises an improved hardness and heat distortion temperature.
- the folded core structure can be water impermeable, the folded core structure can be used as a water barrier.
- the flooring composite can also be used at locations having high humidity and/or on moist grounds.
- Heating means can also be small tubes in which a heated medium can flow through, such as in an underfloor heating.
- the fibers comprised in the skin layer are filaments or staple fibers.
- the fibers comprised in the skin layer are filaments.
- the bonding of the fibers comprised in the skin layer can be chemical bonding, mechanical bonding and/or thermal bonding.
- the bonding of the fibers comprised in the skin layer is a chemical bonding and/or thermal bonding.
- any suitable thermoplastic polymer and/or thermoplastic elastomeric polymer can be used.
- the polymer of the sheath has a melting temperature which is lower than the melting temperature of the polymer of the core.
- the sheath of the bicomponent fibers comprises a thermoplastic polymeric material or a thermoplastic elastomeric polymeric material.
- At least one edge preferably at least two edges, more preferably at least three edges and most preferably all edges of the material comprise a first part of a form-fit connection and/or a second part of a form-fit connection.
- the heated synthetic polymer comprised in the folded core structure can be thermoformed into a form of the first part of a form-fit connection and/or into a form of the second part of a form-fit connection.
- a mold can be used, which can have the negative form of the first part of a form-fit connection and a mold which can have the negative form of the second part of a form-fit connection.
- the mold used for providing the first part of a form-fit connection has the form of the second part of the form-fit connection and vice versa.
- thermoplastic polymeric material or thermoplastic elastomeric polymeric material or of the same family of thermoplastic polymeric material or thermoplastic elastomeric polymeric material, the material can be easily recycled.
- the synthetic polymer comprised in the base layer can be used for bonding the cover layer to the base layer.
- the fibers comprised in the skin layer are filaments
- the dimensional stability of the textile fabric, at least in plane of the skin layer is improved due to the fact that forces affecting on the skin layer can be distributed along the whole length of the filaments and thus over an enlarged area of the skin layer.
- the fibers comprised in the skin layer of the skin layer are bonded at their crossing points. This will improve the aforementioned effect.
- any suitable thermoplastic polymer and/or thermoplastic elastomeric polymer can be used.
- the polymer of the sheath has a melting temperature which is lower than the melting temperature of the polymer of the core.
- the core of the bicomponent fibers comprises a thermoplastic polymeric material or a thermoplastic elastomeric polymeric material.
- the core of the bicomponent fibers comprises a thermoplastic polymeric material selected from a group consisting of polyolefins, in particular polyethylene (PE) or polypropylene (PP), polyesters, in particular polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT) or polyetylene-1 ,2-furandicaboxylate (PEF), polyamides, in particular polyamide 6 (PA6) or polyamide 6,6 (PA6,6), polyetherketones (PEK), polyetheretherketones (PEEK), polyetherketoneketones (PEKK), polyvinyl butyral (PVB), polycarbonate (PC), polyether, polyetheresters, copolymers and mixtures thereof.
