Definitions

  • the present invention relates to an artificial lawn comprising a substrate layer to which synthetic fibres projecting from the substrate layer are attached, wherein said synthetic fibres are composed of fibres comprising a core of a synthetic material and a cladding, which core and which cladding are made of different materials.
  • Such a type of artificial grass is known per se from European patent EP 0 996 781 granted to the present applicant, in which a yarn containing polyamide is used for producing artificial grass, wherein said yarn, in addition to polyamide, also contains a polyolefin compound selected from the group consisting of polypropylene, LLDPE and a block copolymer of polypropylene and polyethylene.
  • a method in which the yarn is obtained by means of co-extrusion in which the yarn is obtained by means of co-extrusion. During such co-extrusion the cladding consists of polyamide, whilst the core consists of one of the aforesaid synthetic materials.
  • the layer of synthetic material is composed of at least two layers of different synthetic materials, which co- extrusion step is claimed to accomplish a separation of the various properties of the synthetic materials that are used.
  • the layer of synthetic material is composed of a core layer of a first synthetic material, which core layer is surrounded on both sides by one or several outer layers, each consisting of a different synthetic material, whilst a hydrophilic additive, for example ethylene vinyl alcoholcopolymer or polyhydroxyethyl methylacrylate, can be used as the outer layer of the co-extrusion fibre.
  • the yarn is a so-called tape filament consisting of a core layer and two outer layers of a material different from the material of the core layer, said core layer comprising polyester and/or polyolefin material and said outer layers comprising high density polyethylene.
  • Japanese patent publication JP 2003 342848 discloses a yarn for artificial turf, which consists of a conjugated yarn of a resin composition, comprising 70-99 wt.% nylon (polyamide) and 1-30 wt.% polyethylene as the inner layer and polyethylene as the outer layer.
  • This problem does not occur with natural grass, which natural material has a high water content and is soft to the touch, so that the friction with the skin will be high.
  • Said high friction is disadvantageous from a viewpoint of sustaining skin damage, but because of the fact that natural grass will wear off slightly upon contact, burns do not occur upon contact between the skin and the natural grass.
  • natural grass is soft and will grow again after wearing off, in which connection it can moreover be noted that the relatively soft nature of natural grass also contributes towards obtaining a good resilience.
  • the selection of the materials used for the artificial grass generally involves a controversy.
  • the material used for the artificial grass is a soft material, for example, which has a large range of elasticity. Such a characteristic results in a good resilience, but also in a high degree of friction, which latter aspect will lead to an excessive adherence of the skin to the artificial grass upon making a sliding tackle, and thus inevitably to skin damage, which is undesirable.
  • These materials are assessed as exhibiting disadvantageous heat development characteristics in the case of such sliding tackles, in spite of the fact that because of the high degree of friction, the contact time between the skin and the artificial grass remains limited.
  • the material used for the artificial grass may also be a hard material having a small range of elasticity, which results in a poor resilience, but in which the amount of friction is limited. The limited amount of friction will lead to less skin damage.
  • said hard materials are assessed as exhibiting advantageous heat development characteristics in the case of sliding tackles, because the contact time is longer.
  • Another object of the present invention is to provide and artificial grass which exhibits a high degree of durability and which can be composed of commercially available materials.
  • Another object of the present invention is to provide a synthetic fibre which obviates the need to inundate the artificial lawn
  • the present invention as referred to in the introduction is characterised in that the material for the cladding has a hydrophilicity which is higher than the hydrophilicity of the material used for the core, and wherein the material for the cladding is selected from the group consisting of polyurethane cellulose, chitosan, polyvinyl alcohol and derivatives thereof, or a combination thereof and wherein the derivatives of cellulose are chosen from the group consisting of viscose, ethyl cellulose cellulose acetate butyrate (CAB), cellulose acetate propionate (CAP), cellulose (di)acetate and cellulose (tri)acetate.
  • CAB ethyl cellulose cellulose acetate butyrate
  • CAP cellulose acetate propionate
  • cellulose (di)acetate and cellulose (tri)acetate cellulose (tri)acetate.
  • the artificial grass When such type of artificial grass is used, the artificial grass will exhibit a certain degree of moisture absorption thereby accomplishing one or more of the aforesaid objects Since the artificial grass according to the present invention feels slightly moist, a good ball roll will be obtained when playing a ball game, in particular field hockey Moreover, in the case of a contact sport, in particular soccer, the risk of harmful injuries, for example after a sliding tackle, will be minimized.
  • the cladding-core structure ensures that the entire core area is surrounded by the cladding.
  • An artificial lawn comprises a substrate layer, to which synthetic fibres projecting from the substrate layer are attached, which has preferably been done by mechanically connecting the synthetic fibres to the substrate layer, for example by means of a weaving, knitting or tufting technique, so that the synthetic fibres more or less approximate the natural grass lawn with upright grass stalks.

  • Chitosan is a linear polysaccharide, which is obtained from chitin.
  • a special advantage of chitosan is the fact that it exhibits a good adhesion to the core material, whilst in addition it has antibacterial characteristics.
  • a suitable material for the core is a material selected from the group consisting of polyesters, polypropylene, ethyl vinyl acetate (EVA), saturated styrene thermoplastic elastomer (SEBS), polyamides, polyethylene compounds and copolymer of ethylene and acrylate, or combinations thereof

  • the present artificial grass can be produced in a number of ways.
  • One way is to first dissolve the cladding material, if possible, whereupon the thus obtained solution is applied to the core material, after which the solvent used is removed, whilst the core material may have been preactivated.
  • a co-extrusion process is used, which possibility is contingent upon the cladding material being meltable, and thus extrudable.

  • the material used for the cladding may also comprise one or more additives, for example additives which lead to a better absorption and moisture release additives which inhibit the growth of algae and/or fungi, additives which influence the elasticity of the artificial grass fibre as such, additives which provide the UV resistance, additives which influence the rolling resistance of the fibre, additives which impart colour to the fibre.
  • additives for example additives which lead to a better absorption and moisture release additives which inhibit the growth of algae and/or fungi, additives which influence the elasticity of the artificial grass fibre as such, additives which provide the UV resistance, additives which influence the rolling resistance of the fibre, additives which impart colour to the fibre.
  • Polyamide 6 was extruded and the thus obtained core material, in the form of bands or monofilaments, was additionally washed with hot water so as to remove the so-called spin finish.
  • the thus extruded core material was subsequently passed through a bath with a solution of an adhesion promoter, using a solution of fumaric acid, in particular 1 - 2 % fumaric acid in an azeotropic mixture of ethanol and water, and a residence time of 10 - 30 seconds.
  • Another suitable adhesion promoting agent is terephthalic acid.

  • a coagulation bath in particular an aqueous composition comprising 9 wt.% sulphuric acid and 13 wt.% sodium sulphate, with the viscose being regenerated and thus converted into cellulose.
  • the core material thus coated with the cladding layer was dried and washed with water, if necessary.
  • the thus obtained artificial grass fibre can be described as a fibre which comprises a very resilient core and a very thin cladding, which is hydrophilic and which provides an improved sliding interaction in comparison with a commercially available artificial grass fibre which does not comprise a cladding that exhibits a hydrophilicity different from the hydrophilicity of the material used for the core.

  • Polyamide 6.6 was used as the core material, and in this case the cladding material to be processed by co-extrusion must be meltable, with the following materials being used: cellulose (di)acetate, cellulose (tri)acetate and polyvinyl alcohol.
  • the cladding material was coated onto the core material by co-extrusion.

  • the thus obtained fibre has a very resilient core and a hydrophilic cladding, which leads to an improved sliding interaction in comparison with artificial grass fibres not having a hydrophilic outer layer.
  • the core material extruded in Examples 1 was used, and the core material obtained in the form of filaments was immersed in a 1 N hydrogen chloride (HCl) solution for a prolonged period of time, maximally 24 hours, so as to effect partial hydrolysis of the amide functions in the polyamide.
  • the thus treated filaments were washed with water repeatedly and subsequently exposed to an aqueous solution containing 9 parts by volume of di-epoxy butane, 1 part by volume of ethanol and 1 part by volume of sodium carbonate (0.025 M in water). Said exposure took place at a temperature of 80 °C for a period of 15 hours.

  • the polymer was dissolved in a suitable solvent, for example o-dichlorobenzene, and subsequently a suitable initiator, for example tertiary butyl peroxide, and maleic acid anhydride were admixed in an amount of 10 wt.% and 1 wt.%, respectively, based on the polymer. After heating for 1 hour at a temperature of 170 °C in an atmosphere of nitrogen, the reaction product was purified by precipitation in boiling acetone.
  • the obtained product is a polymer chain, in which about 0.05 % of the carbon atoms present therein have a hydrophilic group.
  • the grafts thus provided can be hydrolysed by maintaining the obtained filaments in boiling water for about 10 minutes.
  • the anhydride functions will be converted into carboxyl functions, resulting in a smaller angle of contact with water, so that there will be a strong adhesion with water.

  • a treatment with UV radiation was carried out.
  • the treatment thus used comprised exposure for 1 - 7 minutes to a UV lamp which also emits radiation in the wavelength range of 200-300 nm, using an intensity of 2500-6000 ⁇ W/cm 2 and a temperature of 35-85 °C, preferably a temperature higher than 60 °C, because maleic acid anhydride will melt at said temperature, enabling it to react better.
  • a UV lamp which also emits radiation in the wavelength range of 200-300 nm, using an intensity of 2500-6000 ⁇ W/cm 2 and a temperature of 35-85 °C, preferably a temperature higher than 60 °C, because maleic acid anhydride will melt at said temperature, enabling it to react better.
  • the present inventors concluded that 70-90 % of the added maleic acid anhydride had been grafted on the carbon chain. After termination of the photo grafting process, the unreacted reagents can be removed by washing with acetone, followed by water.
  • the hydrolysis step mentioned in the above Examples 5-8 is omitted if subsequently a cladding material is to be applied. More in particular, the hydrolysis step is carried out if the core material is not coated with a cladding.
