Definitions
- the present invention relates a carpet with a high light reflectance value, and a method for producing such carpet.
- the amount of light in a room evidently depends on the illumination, either by sun or artificial light, but also by the way the light is absorbed or reflected by the room and the objects placed therein.
- the 2008 report BS8493 from the British Standards Institution provides a method for quantifying the amount of reflection of light by a certain object, with its so called light reflectance value (LRV), which is defined as the total quantity of visible light reflected by a surface (e.g. floorings, ceilings, walls and furniture), at all wavelengths and directions when illuminated by a light source, which may be sunlight or artificial light.
- LUV light reflectance value
- the LRV scale runs from 0, which is a perfectly absorbing surface (assumed to be totally black), up to 100, which is a fully reflective surface (considered to be perfectly white). Because of practical influences in any application, black is always greater than 0 and white never equals 100. Additional to colour, the structure and luster (gloss) of the product or surface can influence the LRV. LRV measurements are best performed using a spectrophotometer. This equipment accurately and directly measures the LRV of flat and curved items, matt and lustered (including carpet).
- the method for manufacturing a carpet tile comprises the steps of tufting onto a tuft substrate, either loop pile / cut pile or combination of those or the technique of fibre bonding, subsequently applying a primary coating (e.g. SBR / polyacrylates / polyolefin / polyesters) to the top-cloth substrate in order to fix the pile yarn, and then applying a secondary coating (polyolefin / bitumen / EVA / PVC) to the primary coating.
- a primary coating e.g. SBR / polyacrylates / polyolefin / polyesters
- secondary coating polyolefin / bitumen / EVA / PVC
- carpet tiles it may be finished with a glass scrim and/or protection fleece of any colour.
- yet another way of influencing the amount of light in a room may be to project light through the carpet into the room.
- the carpet may for instance be laid on a transparent (for instance glass) floor, or one or more light sources may be applied under the carpet, to shine light through at least part of the carpet.
- the light may be a constant and uniform light, but (time dependent) patterns and colours are thinkable too.
- similar requirements may be set to the carpet as for obtaining a high reflectance value. It is a goal of the present invention to take away the above disadvantages of the prior art, and to propose a carpet that contributes to visual ergonomics and lighting plans.
- the invention thereto proposes a method for manufacturing a carpet, comprising tufting yarns onto a substrate and then pre-coating the substrate, wherein the combination of the yarns and the substrate has a light reflectance value above 30, and more in particular above 35.
- the substrate may be manufactured by needling fibres to become a substrate, and the yarns may be tufted onto the substrate into loop pile.
- the yarns may for example be made of one ore more materials from the group of PP, PA (e.g. PA6, PA66, PA6.10, PA10, PA11, PA12), PET, PTT or PBT, and may be based on white (overdyable) yarns or solution dyed yarns.
- PTT Poly Trimethylene Terephtalate
- PBT Poly Buthylene Terephtalate
- PA Poly Trimethylene Terephtalate
- PBT Poly Buthylene Terephtalate
- PBT has, compared to PA, a very low water take-up of ca. 0.4% compared to a range between 2 - 8% for polyamides, which reduces dye-ability as well as stain-ability on one hand but also good carpet tile dimensional stability on the other hand.
- PTT/PBT have also intrinsic, excellent chemical resistance, which is resulting in very good stain resistant carpet fibres.
- polyesters including PBT yarns, hotmelt PET/PTT/PBT precoating as well as PET/PTT/PBT secondary backing.
- the substrate or backing may be a woven or non-woven backing.
- PET / PP or bi-component PET / PP fibres can be used for this primary backing, consisting of a PET core, manteled with a PP skin, for improved dimensional stability, but moreover for the soil and stain resistance, avoiding carpet tile edges to soil.
- the substrate may be pre-coated with a polyolefin such as HYPOD or SBR, whitened with a filler, such as MgC0 3 , Ti0 2 , ATH and/or CaC0 3 or others.
- a polyolefin such as HYPOD or SBR
- a filler such as MgC0 3 , Ti0 2 , ATH and/or CaC0 3 or others.
- MgC0 3 , Ti0 2 , ATH and/or CaC0 3 may have a chemical purity higher than 90%, in particular more than 95%, and preferably even more than 99%.
- a polyolefin or SBR with ATH had proven to be very effective for obtaining a high reflectance value.
- CaC0 3 and MgC0 3 may be preferred.
- ATH may be added for e.g. fire retardancy.
- a pre-coating recipe that appeared to be very suitable for a carpet, in particular a light transparent carpet comprises a polyolefin and / or a SBR mixture with a filler consisting of a mixture of 30% CaC0 3 , 25% MgC0 3 / 50% ATH.
- This mixture may be optimised in shifting percentages of each ingredient (resp. in the range of CaC0 3 (0- 70), MgC0 3 (0-70), ATH (30-100), and even additional Ti0 2 (0-5).
- the above mixture further enables to meet the (weight and fire retardancy) requirements set to carpet tiles.
- the method according to the invention may comprise applying a very light coloured secondary heavy coating, which can for example be a specific polyolefin, PVC, PVB, EVA or a synthetic bitumen.
- a very light coloured secondary heavy coating which can for example be a specific polyolefin, PVC, PVB, EVA or a synthetic bitumen.
- the viscosity behaviour (process) on one hand as well as temperature resistance, flexibility, mechanical strength and dimensional stability of the product are key polymer blend characteristics.
- Suitable recipes for the heavy coating layer are a specific polymer blend based on polyolefin copolymers, tackifiers and wax/oil which may be filled with CaC0 3 and/or ATH and/or other salts, e.g. NaCl or MgC0 3 may be used.
- the polyolefin copolymers, in particular block copolymers are suitable, due to their spacious molecular geometry, which has proven to have very good light transmitting properties.
- the filler preferably has a high purity (>90%), high whiteness (>90%), and particle size ranging from ca. 1 ⁇ - 300 ⁇ .
- a heavy coating recipe that appeared to be very suitable for a carpet comprises a mixture of about 50% tackifier, about 30% olefin block copolymer and about 20% oil-wax. This mixture may be optimised in shifting percentages of each ingredient with max +/- 20%. (e.g. 35% tackifier, 35% olefin block copolymer and 30% of oil/wax)
- the filler level may vary between 20 to 80%, and more in particular 60 - 75%.
- TPE's thermoplastic elastomers
- TPU's Thermoplastic PolyUrethene
- TPO's Thermoplastic polyolefins
- TPO's based on block co-polymers based on ethene with e.g. blocks butane and/or hexane and/or octane and/or maleic anhydride proved to be very suitable.
- Tackifier either based on rosin esters or based on hydrogenated hydrocarbon resins, (a selection of e.g. Eastman Staybelite, Foralyn, Foral, Pentalyn, Regalite, Regalrez, Eastotac, Piccotac types) may be selected based on adhesion properties as well as VOC emission profiles. Oil (white mineral) and Waxes (mixture of saturated hydrocarbons) are added for processability (viscosity), softer material at room temp and, after application of heavy coating faster solidification during processing.
- the present invention further relates to carpet comprising loop pile yarns tufted onto a substrate, the substrate having a precoat with a polyolefin or SBR with a filler comprising one or more components from the group of MgC0 3 , CaC0 3 , ATH and/or Ti0 2 and a heavy coating layer comprising a polymer blend based on a synthetic bitumen or polyolefin co-polymer.
- carpets may in particular be suitable to transmit lights when they are arranged on a light source.
- the filler may comprise for instance MgC0 3 , CaC0 3 , ATH and/or Ti0 2 with a chemical purity higher than 90%, and the heavy coating layer further comprises tackifiers and wax/oil, filled with one or more components from the group of CaC0 3 , ATH, NaCl, MgC0 3 .
