Definitions

  • the invention relates to a method of reducing the coefficient of friction of the fibres for forming a field of artificial grass by applying on the fibres an agent for reducing the coefficient of friction, which fibres are mainly produced from a polymer material, said agent being based on a silicone elastomer.
  • an elastomeric fibre is formed, based on a silicone compound which may form an elastomer, such as dimethylpolysiloxane, a better adherence is obtained than with a silicone oil, that does not form an elastomer, but the resistance of said coating against being rubbed off can be improved. Further reserach has been carried out to improve the fields of artificial grass, with the result that the adherence of the silicone elastomer to the polymer material from which the fibres of artificial grass are produced has been improved by using the method according to the invention, which is characterized in that one uses a dimethylpolysiloxane terminating with hydroxyl and/or amino groups.
  • the silicone elastomer is derived from a compound having formula 1 of the formula sheet, for which z is the same or different being an integer equal to or higher than 0 and y is an integer being equal to or higher than 1. It is preferred that z and y are lower than 20.
  • This is a silicone compound such a dimethylpolysiloxane having terminating OH-groups and terminating NH2-groups.
  • Such dimethylpolysiloxane compounds are in general known from US patent 4,541,936.
  • an aminofunctional methylsiloxane has been used to improve the properties of textile produced from yards or fibres so that the hand and moisture absorbability of the fibres is improved.
  • no information has been disclosed in order to improve artificial grass fields.
  • EP-A-156,102 it is known to treat the fibres of mink-simulating piles with an agent to obtain a natural fur-like appearance and hand (draping property) by applying on the fibres an organopolysiloxane.
  • no indication has been given concerning the improvement of an artificial grassfield.
  • dimethylpolysiloxane having terminally hydroxyl groups and/or amino groups also other substances reducing, the coefficient of friction can be added. With said substance a synergetic action can be obtained.
  • Further substances for reducing the coefficient of friction to be mentioned are especially fatty acid condensates obtained by reacting fatty acids having 12-22 carbon atoms with an alcohol, amine or alcohol amine.
  • quaternary ammonium compounds having formula 2 of the formula sheet may be used, in which R1 is an alkyl group having 12-22 carbon atoms, R2 and R3 are the same or different alkyl groups having 1-22 carbon atoms and R4 is an alkyl group having 1-4 carbon atoms and A is a salt forming ion.
  • diquaternary ammonium compounds having formula 3 of the formula sheet whereby R1, R2, R3, R4 and A have the same meaning as it is indicated above and in which x has a value of 2 or 3.
  • waxes such as vegetable and animal waxes, paraffin wax or polyalkylene wax having a melting point higher than 35 °C.
  • the dimethylpolysiloxane is preferably applied in a quantity of 5-35 g/m2 of artificial grass.
  • the data from this experiment show that the field of artificial grass whose fibrous material had a coating on the basis of the silicone elastomer, based on dimethylpolysiloxane with terminating hydroxyl and/or amino groups according to the invention the grass was less flattened. This artificial grass will undergo less agening when a coating according to the invention is applied.
  • a limited life of the artificial grass manifests itself by splitting and/or pulverizing of the ends of the fibres. Said agening is effected faster by means of the "tread test". It appears thereby that the other parts of artificial grass having no coating or having a coating on the basis of silicone oil are split faster in several filaments in the longitudinal direction than when the silicone elastomer according to the invention has been applied. From these experiments it appears that fields of artificial grass can be improved by providing the fibrous material with a coating consisting of a silicone elastomer according to the invention. It also is possible to re-treat the existing fields of artificial grass with a silicone elastomer according to the invention.
  • This product was sprayed on a fibrous material of which an artificial grass was made, in a quantity of 200 cm3 per m3.
  • the fibrous material or the artificial grass made of said fibrous material was heated to 130 °C for 10 minutes.
  • a well-adhering elastomeric film was formed around the artificial grass material.
  • Such an elastomeric film may be provided on various materials of which artificial grass fibres are made, such as fibres which can be frizzed or without frizzing made of polypropene, fibres made by co-extruding various polymers, fibres made of block copolymers of various polymers or made of polyamine.
