KUNSTIG GRESS BYGGET OPP AV FIBRE SOM BESTÅR AV EN KJERNE OG EN OMHYLLING SÅ VEL SOM EN KUNSTIG PLEN BYGGET OPP AV DETTE. ARTIFICIAL GRASS IS BUILT UP OF FIBERS CONSISTING OF A CORE AND A COVER AS WELL AS AN ARTIFICIAL LAWN BUILT UP FROM THIS.
Foreliggende oppfinnelse angår et kunstig gress bygget opp av fibre som består av en kjerne og en omhylling eller kapsling der kjerne og omhyllingen består av et plastmateriale. The present invention relates to an artificial grass made up of fibers which consist of a core and a covering or casing where the core and the covering consist of a plastic material.
En slik type kunstig gress er i og for seg kjent fra EP 0 996 781 i foreliggende søkers navn og som utviklet seg fra WO 99/04074, der et polyamidholdig garn benyttes for fremstilling av kunstig gress og der garnet, ved siden av polyamid, også inneholder en polyolefinforbindelse valgt fra gruppen bestående av polypropylen, LLDPE og en blok-kopolymer av polypropylen og polyetylen. I tillegg til fremgangsmåten for fremstilling av et garn som er kjent fra dette, der polymeren ekstruderes for å danne monofila-menter som deretter prosesseres til bånd og der flere bånd tvinnes for å danne et garn, og der det beskrives en metode der garnet oppnås ved hjelp av en koekstruderingsprosess. Når en slik ekstruderingsprosess benyttes, består omhyllingen av polyamid, mens kjernen består av et av de ovenfor nevnte plastmaterialer. Such a type of artificial grass is known per se from EP 0 996 781 in the name of the present applicant and which developed from WO 99/04074, where a polyamide-containing yarn is used for the production of artificial grass and where the yarn, next to polyamide, also contains a polyolefin compound selected from the group consisting of polypropylene, LLDPE and a block copolymer of polypropylene and polyethylene. In addition to the method of making a yarn known from this, in which the polymer is extruded to form monofilaments which are then processed into ribbons and in which several ribbons are twisted to form a yarn, and in which a method is described in which the yarn is obtained by using a coextrusion process. When such an extrusion process is used, the casing consists of polyamide, while the core consists of one of the plastic materials mentioned above.
Fra publikasjonen WO 2004/106601 er det kjent et garn for en kunstig plen der garnet er et såkalt teipfilament bestående av et kjernesjikt og to yttersjikt av et materiale forskjellig fra det i kjernesjiktet og der kjernesjiktet inneholder polyester og/eller po-lyolefinmateriale og der de ytre sjikt inneholder høydensitetspolyetylen. From the publication WO 2004/106601, a yarn is known for an artificial lawn where the yarn is a so-called tape filament consisting of a core layer and two outer layers of a material different from that in the core layer and where the core layer contains polyester and/or polyolefin material and where the outer layer contains high density polyethylene.
Det japanske patentet JP 2003 342848 beskriver et garn for en kunstig plen som består av et konjugert garn dannet av en harpiksblanding bestående av 70-99 vekt% nylon (polyamid) og 1-30 vekt% polyetylen som innersjiktet og poletylen som ytter-sjiktet. The Japanese patent JP 2003 342848 describes a yarn for an artificial lawn consisting of a conjugated yarn formed from a resin mixture consisting of 70-99% by weight nylon (polyamide) and 1-30% by weight polyethylene as the inner layer and polyethylene as the outer layer.
Et velkjent fenomen med kunstig gress og særlig hvis det kunstige gress benyttes for fotballspill, er opptreden av brannsår når spillerne foretar glidetaklinger. Dette pro-blem opptrer ikke med naturlig gress da det naturlige materiale har et høyt vanninn- hold og føles mykt ved kontakt slik at friksjonen med huden vil være høy. Denne høye friksjon er ugunstig med henblikk på hudskade, men på grunn av det faktum at naturlig gress vil slites noe bort ved kontakt inntrer ikke brannsår ved kontakt med naturlig gress. I tillegg til dette skal det bemerkes at naturlig gress er mykt og vil vokse igjen etter å ha vært slitt bort, i hvilken forbindelse det videre kan påpekes at den relativt myke art av naturlig gress også bidrar til gunstige elastiske/fjærende egenskaper. A well-known phenomenon with artificial grass, and especially if the artificial grass is used for football games, is the appearance of burns when the players make sliding tackles. This problem does not occur with natural grass as the natural material has a high water content and feels soft on contact, so the friction with the skin will be high. This high friction is unfavorable in terms of skin damage, but due to the fact that natural grass will wear away somewhat on contact, burns do not occur on contact with natural grass. In addition to this, it should be noted that natural grass is soft and will grow again after being worn away, in which connection it can also be pointed out that the relatively soft nature of natural grass also contributes to favorable elastic/resilient properties.
På den annen side er det generelt en kontrovers når det gjelder materialene for an-vendelse for kunstig gress. Materialet som benyttes for kunstig gress, er et mykt materiale som for eksempel har et høyt elastisitetsområde. En slik egenskap gir god ettergivenhet, men også en høy grad av friksjon og det siste aspektet vil føre til eksessiv adhesjon av huden til det kunstige gress når det foretas en glidetakling og dette fører uunngåelig til skade på huden, noe som er uønsket. Nevnte materialer be-dømmes som utilfredsstillende hva angår varmeutviklingen som skjer når en glidetakling foretas, på tross av det faktum at på grunn av den høye friksjonsgrad er kontakt-perioden mellom hud og kunstig gress begrenset. Materialet som benyttes for det kunstige gress kan også være et hardt materiale med et lite elastisitetsområde, noe som fører til uønskede egenskaper hva angår elastisitet eller ettergivenhet, men også til mindre friksjon. Reduksjonen hva angår graden av friksjon vil føre til mindre hudskade. I tillegg til dette er nevnte harde materialer vurdert som tilfredsstillende hva angår varmeutviklingen under glidetaklinger fordi kontakttiden er lenger. On the other hand, there is generally a controversy regarding the materials to be used for artificial grass. The material used for artificial grass is a soft material which, for example, has a high elasticity range. Such a property gives good compliance, but also a high degree of friction and the last aspect will lead to excessive adhesion of the skin to the artificial grass when a sliding tackle is made and this inevitably leads to damage to the skin, which is undesirable. Said materials are judged to be unsatisfactory in terms of the heat generation that occurs when a sliding tackle is made, despite the fact that due to the high degree of friction, the contact period between skin and artificial grass is limited. The material used for the artificial grass can also be a hard material with a small elasticity range, which leads to undesirable properties in terms of elasticity or compliance, but also to less friction. The reduction in the degree of friction will lead to less skin damage. In addition to this, the aforementioned hard materials are rated as satisfactory in terms of heat generation during sliding tackles because the contact time is longer.
Et formål med den foreliggende oppfinnelse er å tilveiebringe en spesiell type kunstig gress som imiterer de fordelaktige egenskapene ved naturlig gress, og spesielt hva angår elastisitet og oppførsel under glidetaklinger, i så stor grad som mulig. An object of the present invention is to provide a special type of artificial grass that imitates the beneficial properties of natural grass, and especially in terms of elasticity and behavior during sliding tackles, to the greatest extent possible.
Et ytterligere formål med den foreliggende oppfinnelse er å tilveiebringe et kunstig gress som viser en høy grad av holdbarhet og som kan bestå av kommersielt tilgjeng-elige materialer. A further object of the present invention is to provide an artificial grass which shows a high degree of durability and which can consist of commercially available materials.
I henhold til den foreliggende oppfinnelse blir det kunstige gress det henvises til i inn-ledningenkarakterisertav den karakteriserende delen av krav 1. According to the present invention, the artificial grass referred to in the introduction is characterized by the characterizing part of claim 1.
Én eller flere av de ovenfor angitte formål oppnås ved bruk av en slik type kunstig gress. Fordi et mykt materiale benyttes for kjernen kan det oppnås gunstige egenskaper hva angår elastisitet, uten at de ovenfor nente ufordelaktige overflateegenskaper spiller noen rolle. Fordi omhyllingen er bygget opp av et relativt hardt materiale trek-ker man dessuten fordel av de relativt gunstige overflateegenskaper, det vil si en lav grad av hudskade som et resultat av den lave adhesjon til huden. Dessuten er de One or more of the purposes stated above are achieved by using this type of artificial grass. Because a soft material is used for the core, favorable properties can be achieved in terms of elasticity, without the above-mentioned disadvantageous surface properties playing any role. Because the covering is built up from a relatively hard material, you also benefit from the relatively favorable surface properties, that is, a low degree of skin damage as a result of the low adhesion to the skin. Besides, they are
ugunstige egenskaper hva angår elastisitet minimalisert ved bruk av et hardt materiale for omhyllingen. unfavorable properties in terms of elasticity minimized by using a hard material for the sheath.
Uttrykkene "myk" og "hard" slik det benyttes i foreliggende beskrivelse, må tolkes i forhold til hverandre, i hvilken forbindelse det er spesielt viktig at materialet for omhyllingen er hardere enn det materialet som benyttes for kjernen. Det myke materialet i kjernen vil ha en elastisitetsmodul (i henhold til ASTM D638) på maksimalt 500 MPa, fortrinnsvis maksimalt 300 MPa. Det harde materialet for omhyllingen vil ha en elastisitetsmodul (i henhold til ASTM D638) på minimum 500 MPa og fortrinnsvis minimum 750 MPa. The terms "soft" and "hard" as used in the present description must be interpreted in relation to each other, in which connection it is particularly important that the material for the covering is harder than the material used for the core. The soft material in the core will have a modulus of elasticity (according to ASTM D638) of a maximum of 500 MPa, preferably a maximum of 300 MPa. The hard material for the sheath will have a modulus of elasticity (according to ASTM D638) of a minimum of 500 MPa and preferably a minimum of 750 MPa.
I en spesiell utførelse er materialet for omhyllingen fortrinnsvis valgt fra gruppen bestående av polyetylenforbindelser, polypropylen og fluorpolymerer eller kombinasjoner derav, der polyetylenforbindelsene er valgt fra gruppen bestående av høydensitetspo-lyetylen (HDPE), middelsdensitetspolyetylen (MDPE), lavdensitetspolyetylen (LDPE), lineær lavdensitetspolyetylen (LLDPE) og anhydridmodifiserte polyetylenforbindelser. In a particular embodiment, the material for the casing is preferably selected from the group consisting of polyethylene compounds, polypropylene and fluoropolymers or combinations thereof, where the polyethylene compounds are 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.
I en spesiell utførelse av oppfinnelsen er omhyllingen på den kunstige fiber relativt tynn, det vil si at tykkelsen for omhyllingen er slik at volumet utgjør 1-40 % og særlig 1-10 % av volumet av hele fiberen. En slik liten tykkelse for omhyllingen gjør det mulig å trekke nytte av de høye spesifikke varmeegenskaper for kjernematerialet, noe som vil føre til redusert opptreden av brannsår. In a particular embodiment of the invention, the coating on the artificial fiber is relatively thin, that is to say that the thickness of the coating is such that the volume constitutes 1-40% and in particular 1-10% of the volume of the entire fiber. Such a small thickness for the sheath makes it possible to take advantage of the high specific heat properties of the core material, which will lead to a reduced occurrence of burns.
Det kunstige gress ifølge oppfinnelsen er viderekarakterisert vedat den kunstige gressfiber er oppnådd ved hjelp av en koekstruderingsprosess der materialet for kjernen og materialet for omhyllingen ekstruderes samtidig og der omhyllingen er i direkte kontakt med kjernen. The artificial grass according to the invention is further characterized in that the artificial grass fiber is obtained using a co-extrusion process where the material for the core and the material for the covering are extruded simultaneously and where the covering is in direct contact with the core.
I henhold til en foretrukket utførelse av oppfinnelsen er materialet for kjernen polyamid og materialet for omhyllingen en anhydridmodifisert HDPE. According to a preferred embodiment of the invention, the material for the core is polyamide and the material for the sheath is an anhydride-modified HDPE.
Oppfinnelsen angår videre en kunstig plen eller gressmatte, bygget opp fra kunstig gress som beskrevet ovenfor. The invention further relates to an artificial lawn or grass mat, built up from artificial grass as described above.
I en spesiell utførelse kan en blanding av for eksempel polyamid og særlig polyamid 12, og et modifisert polyetylen, benyttes for kjernen. In a particular embodiment, a mixture of, for example, polyamide and particularly polyamide 12, and a modified polyethylene, can be used for the core.
For å forhindre delaminering av kjernen og omhyllingen blir et kompatibilitetsmiddel føyd til materialet for kjernen og/eller materialet for omhyllingen, eller begge, der kompatibilitetsmidlet forsterker bindingen mellom materialet i kjernen og materialet i omhyllingen. Det egnede kompatibilitetsmiddel er en kopolymer av etylen og metylakrylat der metylakrylatinnholdet spesielt utgjør mindre enn 50 % og fortrinnsvis rundt 30 %. To prevent delamination of the core and cladding, a compatibilizing agent is added to the material of the core and/or the material of the cladding, or both, where the compatibilizing agent reinforces the bond between the material of the core and the material of the cladding. The suitable compatibilizer is a copolymer of ethylene and methyl acrylate where the methyl acrylate content is in particular less than 50% and preferably around 30%.
