Definitions

  • the present invention relates to an artificial grass built up of fibres that consist of a core and a cladding, which core and which cladding are composed of a plastic material.
  • Such a type of artificial grass is known per se from European patent EP 0 996 781 granted to the present applicant, which evolved out of WO 99/04074, in which a polyamide-containing yam is used for fabricating artificial grass, wherein the yarn, besides polyamide, also contains a polyolefin compound selected from the group consisting of polypropylene, LLDPE and a block copolymer of polypropylene and polyethylene.
  • a method is disclosed in which the yarn is obtained by means of a co-extrusion process.
  • the cladding consists of polyamide, whilst the core consists of one of the aforesaid plastics.
  • the yarn is a so-called tape filament consisting of a core layer and two outer layers of a material different from that of the core layer, wherein the core layer contains polyester and/or polyolefin material and wherein the outer layers contain high-density polyethylene.
  • Japanese patent publication JP 2003 342848 discloses a yarn for an artificial lawn that consists of a conjugated yarn formed 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.
  • a well-known phenomenon with artificial grass in particular if the artificial grass is used for playing soccer thereon, is the occurrence of burns when players make a sliding tackle.
  • This problem does not occur with natural grass, which natural material has a high a water content and which feels soft upon contact, so that the friction with the skin will be high.
  • This high friction is disadvantageous from the viewpoint of skin damage, but because of the fact that the natural grass will wear away slightly upon contact, burns do not occur upon contact with natural grass.
  • natural grass is soft and will grow again after having worn away, in which connection it can furthermore be noted that the relatively soft nature of natural grass also contributes to favourable resilient properties.
  • the material used for the artificial grass is a soft material, for example, which has a large elastic range. Such a property makes for a good resilience, but also a high degree of friction, which latter aspect will lead to excessive adhesion of the skin to the artificial grass when a sliding tackle is made, and thus to inevitable damage to the skin, which is undesirable. Said materials are evaluated as unsatisfactory as regards the heat development that takes place when a sliding tackle is made, in spite of the fact that because of the high degree of friction the period of contact 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 elastic range, which leads to unsatisfactory properties as regards resilience but also to less friction. The reduction as regards the degree of friction will lead to less skin damage. In addition to that, said hard materials are evaluated as satisfactory as regards the heat development during sliding tackles, because the period of contact is longer.
  • Another object of the present invention is to provide an artificial grass which exhibits a high degree of durability and which can be composed of commercially available materials.
  • the artificial grass as referred to in the introduction is characterized in that the material for the core has been selected from the group consisting of polypropylene, ethyl vinyl acetate (EVA), saturated styrene thermoplastic elastomer (SEBS), polyamide and polyethylene compounds, or combinations thereof.
  • EVA ethyl vinyl acetate
  • SEBS saturated styrene thermoplastic elastomer
  • polyamide polyethylene compounds
  • the cladding is built up of a relatively hard material, use is advantageously made of the relatively favourable surface properties, viz. a low degree of skin damage as a result of the low adhesion to the skin. Moreover, the unfavourable properties as regards resilience are minimised by using a hard material for the cladding.
  • the terms "soft” and “hard” as used in the present description must be interpreted in relation to each other, in which connection it is in particular important that the material for the cladding is harder than the material that is used for the core.
  • the soft material for the core will have an elasticity modulus (according to ASTM D638) of maximally 500 MPa, preferably maximally 300 MPa.
  • the hard material for the cladding will have an elasticity modulus (according to ASTM D638) of minimally 500 MPa, preferably minimally 750 MPa.
  • the material for the cladding has preferably been selected from the group consisting of polyethylene compounds, polypropylene and fluor polymers or combinations thereof, wherein the polyethylene compounds have been selected from the group consisting of high density polyethylene (HDPE), medium density polyethylene (MDPE), low density polyethylene (LDPE), linear low-density polyethylene (LLDPE) and anhydride modified polyethylene compounds.
  • HDPE high density polyethylene
  • MDPE medium density polyethylene
  • LDPE low density polyethylene
  • LLDPE linear low-density polyethylene
  • anhydride modified polyethylene compounds anhydride modified polyethylene compounds.
  • the cladding of the artificial fibre is relatively thin, viz. the thickness of the cladding is such that its volume makes up 1-40%, preferably 1-20%, of the volume of the entire fibre.
  • the thickness of the cladding is such that its volume makes up 1-40%, preferably 1-20%, of the volume of the entire fibre.
  • the artificial grass according to the present invention is further characterized in that the artificial grass fibre has been obtained by means of a co- extrusion process, wherein the material for the core and the material for the cladding are extruded simultaneously, with the cladding being in direct contact with the core.
  • the material for the core is polyamide and the material for the cladding is an anhydride modified HDPE.
  • the material for the core is LDPE and the material for the cladding is HDPE.
  • the material for the core is moreover preferably a combination of polypropylene and SEBS and the material for the cladding is polypropylene.
  • Other preferred embodiments of the present artificial grass are characterized in that the material for the core is EVA and the material for the cladding is a fluor polymer, wherein the material for the core also contains polypropylene and/or polyethylene besides EVA and wherein polyvinylidene fluoride (PVDF) is used as the fluor polymer.
  • PVDF polyvinylidene fluoride
  • the present invention furthermore relates to an artificial lawn built up from an artificial grass as described above.
  • a mixture of, for example, polyamide, in particular polyamide 12, and a modified polyethylene can be used for the core.
  • Another suitable material for the core is a combination of LDPE and HDPE.
  • a compatibility agent has preferably been added to the material for the core and/or to the material for the cladding, or to both materials, which compatibility agent enhances the bond between the material for the core and the material for the cladding.
  • a suitable compatibility agent is a copolymer of ethylene and methyl acrylate, with the methyl acrylate content in particular amounting to less than 50%, preferably about 30%.

Abstract

L'invention concerne un drain pour liquides comportant une partie de tuyau détachable pourvue d'un collecteur contre les mauvaises odeurs, placé dans un plan essentiellement horizontal ou raccordé à un tuyau de drainage, la partie de tuyau comprenant des moyens de positionnement pour placer la partie de tuyau dans le tuyau de drainage, ou en raccordement avec celui-ci, suivant une orientation sensiblement univoque. Dans l'un des modes de réalisation, le drain comprend un réceptacle possédant une paroi inférieure et des parois latérales surélevées, les parois latérales surélevées comprenant une première paroi latérale laquelle possède une ouverture de drainage, et le tuyau de drainage est placé sur une surface externe du réceptacle en vue d'un raccordement avec l'ouverture de drainage. Le drain, décrit par l'invention, convient particulièrement bien à une situation où il est positionné dans un sol de finition d'une zone humide dans un bâtiment par exemple, entre autres une salle de bains ou une cabine de douche.
