Definitions

  • the invention relates to a field of artificial grass consisting of a substructure construction and provided thereon a carpet of synthetic fibres with a sand layer distributed between said fibres.
  • the invention also relates to the fibrous material which is intended for being processed into a mat for the field of the intended artificial grass.
  • German patent application 3 204 215 relates to a field of artificial grass whereby sand is strewn in in several layers, whereby the grain size of the sand decreases from the lower lever to the upper level.
  • the first developed fields of artificial grass were intended for tennis and golf whilst the later fields of artificial grass could be used for playing hockey.
  • the requirements made in connection with a field of artificial grass strongly depend on the purpose aimed at or which sport is to be practised on such a field.
  • the field must be flat, well pervious to water and resistant to moisture, to fluctuations in temperature and to ageing, it must be colour fast and resistant to ultraviolet rays.
  • the field of artificial grass should have a damping power which is in relation to the sport to be practised.
  • a hockey field e.g. can thus have a smaller damping power than a soccer field, where a smaller damping power means that the field has a harder feeling. With soccer more jumps and slidings are made, whereby a field with little damping may form a load being too heavy for certain muscles.
  • the damping power of a field of artificial grass is mainly determined by the substructure construction.
  • the present patent application is directed to the artificial grass itself.
  • the first fields of artificial grass which were not strewn in with sand contained more fibrous material per square metre and had the disadvantage that they were comparatively costly and that the sportsman could sustain burns when making falling or sliding movements as a result of the local high rise in temperature on those parts of the body making the sliding movement across the artificial grass. Consequently it is necessary for such fields of artificial grass to be sprayed with water regularly.
  • This disadvantage has overcome to a large extent with the fields of artificial grass that are strewn in with sand.
  • the carpet of synthetic fibres consists of curled or frizzed fibres, whereby the fibres are provided, at least partially and in any case at their upper parts, with a coating film of an elastic material which reduces the coefficient of friction and at the same time extends the power of recovery of the fibre.
  • the strewn-in sand will make the mat containing synthetic fibres heavier so that the mat will remain fixed on the substructure construction and the synthetic fibres will remain upright, also when a kicking movement or sliding movement is made or when the sportsman lands after a jump.
  • the film of the elastic solid substance ensures that the fibre will keep its elastic properties longer and is not non-slipping.
  • the frizzing or curling can be provided in the fibre in various manners, e.g. by knitting - deknitting.
  • the frizzing provided is such that the length of the fibre is reduced by 20-40%.
  • the sand which grazing effect is avoided as much as possible, which can be achieved by choosing sand with a round shape of grain, is provided to such a height that the frizzed fibre protrudes to a length of 2-8 mm from the layer of sand, whilst the entire length of pile of the frizzed fibre is 20-28 mm.
  • the sand is preferably quartz sand which particles are round and comparatively soft, for the most part having a grain size of 0.2-0.6 mm.
  • the fibres are provided in a ground foil or tuft bloth pervious to water and on a soccerfield about 25-28 kg of sand per square metre are provided.
  • a field of artificial grass has now been obtained on which the sliding during the game of soccer can be made with the same effect as on a field of natural grass.
  • a material to be used for reducing the coefficient of friction is silicone oil.
  • Providing said silicone oil on the fibre takes place e.g. by spaying the oil, whether or not in a solvent, and then allowing it to dry, possibly while being heated, to 120 ° C so that a solid elastomeric film is formed.
  • the mixture comprising silicone oil can also contain additives such as curing agents and equalizing agents.
  • polypropylene fibres having a pile lenght of about 35 mm are frizzed to a length of 22 mm, whereby approximately 16,000 piles are provided per square metre.
  • the fibres are passed through a tuft cloth, also made of polypropylene, with a joint weight of approximately 1.2 kg/m2.
  • the fibres are provided with a thin film of silicone oil for which purpose 50-100 cc of oil, possibly diluted with an aqueous solution, is provided per square metre of artificial grass.
  • silicone oil for which purpose 50-100 cc of oil, possibly diluted with an aqueous solution, is provided per square metre of artificial grass.
  • the oil After the oil has been provided it becomes elastomeric by hardening the fibres under surrounding-circumstances so that an elastomeric, well-adhering film is formed around the fibres.
  • the oil may also be provided at a later stage when the field of artificial grass has already been played on, so that this treatment can also be carried out as maintenance-treatment.
