Definitions

  • the invention relates to the production of textile- or plastic surfaces covered by fibres by die-casting based on a textile- or plastic material, or without it.
  • the textile- or plastic surfaces covered by die-cast fibres may have various applications.
  • the process according to the present invention can be applied first of all to the formation of artificial lawn. To this very day with the spread of the organized sport activities, mainly ball games, the playing surface of the outdoor sports fields, has been the natural lawn. Its historical reason is that the majority of these kinds of sports has been developed permanently in England rich in rain and grass where the lawn production had not only centuries-old traditions but also excellent natural circumstances, because of the climatic conditions.
  • the process according to the present invention obviously can be applied for any other purposes where preparation of textile- or plastic surfaces covered by fibres are necessary.
  • the artificial lawn has to be placed on some kind of ready-made base, because it could not play the intended role being alone or laying down without suitable ground.
  • the filling material can be selected from quartz sand, rubber granulates and similars.
  • This base performs an elastic up and down movement under the weight of the player thus this playing field becomes similar to a soil of a natural field of excellent quality.
  • the field base with artificial lawn sloping slightly laterally carries away the rainwater from the field by the help of a catchwater (drain) system or a wasteway.
  • the artificial lawn then comes to this base and provides the playing surface together with the suitable filling material.
  • the quartz sand filling material gives the weighting (loading) of the artificial lawn, and guarantees elastic playing surface with great strength gripping together with rubber granulates, thus reducing the chance of the injuries with abrasions, too.
  • the presently accepted solution is the filling of the sand and the rubber after each other or an artificial lawn filling made from rubber granulate mixed with sand.
  • the sand filling serves as a fastener or a weighting material for the artificial lawn.
  • the grain size of 0,3 mm - 0,5 mm prevents the formation of dust; because of its great density it is positioned at the bottom of double-layer filling.
  • the rubber granulate or similar elastic preparation of 0,5 mm - 2,5 mm grain size guarantees among others the elasticity of the field and the clinging of the sports shoes, too.
  • fibrillated cut from folia
  • extruded extruded-textured (handled mechanically and by heat) yarns (fibres)
  • suitable materials for the yarns they are, however, mainly polyethylene, polypropylene and their different copolymers.
  • the thickness of the fibre is the same as the thickness of folia and its width varies according to the wish of the manufacturer and the customer.
  • the fibrillated fibre can be plate- or twisted shaped.
  • the length of the fibres can vary, e.g. in case of field hockey and tennis 10-20 mm, for football 35-70 mm.
  • the looping of the fibres can occur in a straight line, in a zigzag line, in wavy line, and so on. Fibres of different length and with varying quality and thickness are applied in the same carpet, respectively. To the reverse of the carpet a plastic, rubber or other material coating layer resisting to the weather is applied in order to prevent the tensibility of fibres.
  • the fibres of artificial grass are always parallel, their characteristic is that in consequence of the same looping direction they lean in the same direction, their strength is established only with the support of the filling material.
  • the artificial grass fibre lies down sinking down and compacting, therefore this fibre becomes shattered, and breaks. Thus the artificial grass fibre is not able to resist the mechanical effects.
  • JP 9235702 Japanese patent document presents a solution in which the artificial lawn is constituted from thicker and thinner fibres; in this way a very beautiful, "leafy" lawn can be formed, which also retains better the filling material (counterweight).
  • the artificial lawn is prepared from twisted fibres that can be produced by twisting bunches of fibre; twisted and fastened fibres are woven into the fabric in order to form an artificial lawn with excellent durability similar to the natural lawn.
  • the novelty is that an artificial lawn is formed by the application of a different kind of technology; this artificial lawn exceeds the so far known solutions as far as the attractiveness, wear resistance, stability of the quality of the playing surface built from it and suitability are concerned, thus this technology provides more opportunity to the spread and standardization of sports fields furnished with artificial lawn.
  • our invention provides a new process for the production of artificial lawn from a cloth based on a textile cloth, or without it.
  • the most general realization is possible according to Claims 1 and 9.
  • the individual modes can be realized according to the texts formulated in the dependent claims.
  • the process can be characterized as follows: a) knots made from synthetic material are die-cast through holes located in a mainly textile cloth serving as a grounding, or b) knots die-cast from synthetic material are sewed or otherwise fastened to a cloth mainly textile cloth serving as a grounding, or c) panels containing both plastic surface grounding and knots are developed by die- casting, or d) knots die-cast from synthetic material or die-cast panels covered fibres are sewed or otherwise fastened to a plastic ground plate element serving as a grounding.
  • the technology for achieving the given aim is the die-casting (also known as injection moulding) at all the four cases. It is possible to plan unique knots ("bunch of grass") by the suitable planning of the casting-die, forming their shape, density, aesthetical visualization, fibre length, static quality etc., correspondingly to the aim of the application. Applying this technology all the above-mentioned disadvantages of the carpet-looping technology disappear.
  • the casting-die tool can be planned to a given aim, and it is possible to take into consideration the shape and the fibre length that the artificial grass fibre and the artificial grass knot intend to achieve, as well as the nature of the thermoplastic material.
  • the characteristics of the traditional artificial grass are the following: number of artificial grass knots within 1 m 2 , length of fibres, thickness of fibres, and weight of the material of fibres within 1 m 2 .
  • number of artificial grass fibres within 1 m 2 , length of fibres, and weight of fibres within 1 m 2 serve to the characterization of the artificial lawn.
  • the number of the fibres within 1 m 2 is 2400-180000 pieces, and the length of the fibres is between 12 mm and 100 mm.
  • the weight of the fibres depends on the sport for which the artificial lawn is prepared; this value can vary between 300 g and 4500 g.
  • This number can be influenced partly by the form of the aimed die-casting tools or bunches of tools, and partly by the movements of the die-casting heads and the carpet serving as grounding, or in case of sewing of the plastic knots or panels, by the number of the sewing within 1 m 2 .
  • the reason of the change in the number of knots or panels within 1 m 2 can be the suitability to a given play but also can be financial, too. Namely, the less frequent knot number means less cost and for certain sports fields the artificial lawn with less frequent knot number is also suitable.
  • the arrangement for the manufacturing technology of the artificial lawns consists of a roll train serving for the conveyance of a textile cloth reverse rolled up similarly to the traditional carpet-looping production process and of a - die-casting machine and tool or wreath of tools.
  • a die-casting machine have to be used with suitable size (die-casting pressure).
  • the maximum dimension of the wreath of tools thus the size of the artificial lawn pieces, which can be die-cast simultaneously, is limited by the greatest possible die- casting pressure.
  • the material of the artificial grass knot gets directly in die-casting manner into the reverse of the textile cloth from the die-casting tool at a temperature 170 0 C - 300 0 C and at pressure 2.10 s Pa - 3.10 10 Pa (-22000 atm - 300000 atm), where the die-casting tool is positioned on the one side of the textile grounding, and the discharge opening(s) of the die-casting tool(s) are positioned on the other side.
  • the die-casting tool is positioned on the one side of the textile grounding, and the discharge opening(s) of the die-casting tool(s) are positioned on the other side.
  • the die-cast material on the "grass knot” side of the textile cloth solidifies forming knots, while a continuous "film” layer of 0,1 mm - 2 mm thickness is developed from the material of the artificial grass on the side of the die-casting-die.
  • the role of this coating is the same as in the carpet-looping process, i.e. the fibres should be fixed against drawing-off as well as the shape constancy of the carpet and the resistance against the weather should be guaranteed; to this, however, it is not necessary any separate technological step.
  • the strips of the carpet are fixed to each other by sticking on a traditional glass cloth strip or by a sewing technology.
  • the carpet is fixed by quartz sand used for filling the base of the sports field.
  • the die-cast artificial grass knots are prepared one by one or line by line at pressure 2.10 s Pa - 3.10 10 Pa (-22000 atm - 300000 atm) and at temperature 170 0 C - 300 0 C.
  • the knots being finished separately will be sewed or otherwise fixed on the "artificial grass" side of the textile cloth after cooling down and hardening with suitably selected frequency.
  • On the side of the cloth not covered by artificial grass it is possible optionally to apply a plastic-, rubber- or other weatherproof layer with 0,1 mm - 2 mm thickness on behalf of the shape constancy and resistance against weather, whilst it serves simultaneously the protection of sewing.
