- 1. Field of the Invention
- The present general inventive relates to the processing of artificial turf and in particularly, but not solely, to the processing of artificial turf for use in forming a wall structure for a golf course bunker or other formation.
- 2. Description of the Related Art
- Artificial turf comprises an upper surface provided within an array of turf fibers of nylon, polypropylene or other synthetic material upstanding from a backing layer of polyurethane, canvas, latex or other sheet material. Generally larger areas of artificial turf are in-filled with sand and/or another granular material to prevent expansion and contraction with temperature and to hold the artificial turf firmly in-situ.
- Artificial turf has a finite lifespan, particularly when it is used as a surface in sports fields. At present, a high proportion of used artificial turf undesirably ends up in landfill sites.
- UK Patent No. GB2490637B discloses how used artificial turf material can be cut into strips or tiles and then used to create a wall structure for a golf course by forming substantially horizontal layers of the material. This use of reclaimed artificial turf not only significantly reduces waste but it creates an extremely hardwearing and aesthetically pleasing side wall for a golf course bunker. The granular infill in the artificial turf actually benefits the structure because it increases the density of the layers and helps to distribute load and helps to keep the layers together.
- An area of artificial turf which is to be removed and reclaimed for re-use is firstly cut into strips whilst in-situ. The strips are then rolled or stacked, removed from site and then taken to storage before being transported to a site for re-use. Unfortunately, this process can cause the granular infill to fall out of the turf fibers, with a result of the large proportion of the artificial turf cannot be re-used in a satisfactory manner.
- What is need is a method of processing artificial turf which alleviates the above-mentioned problems.
- It is an aspect of the present invention to provide an improved processing of artificial turf.

FIG. 2 b is a magnified view of region A onFIG. 2 a, according to an embodiment. - Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
- In accordance with the present invention, there is a provided a method of processing artificial turf, the method providing an area of artificial turf to be processed, the artificial turf comprising a backing substrate sheet and an upper surface formed by a plurality of artificial fibers upstanding from the backing substrate sheet and a granular infill material disposed between the fibers, wherein the method further comprises applying a binding agent to the upper surface of the turf so as to wet and bind the granular infill.
- The binding agent may be applied at any stage in the method. The binder may, for example, be applied to the upper surface of the turf prior to being reclaimed from a previous environment in which it was used or stored or, alternatively or additionally, the binder may, for example, be applied when the artificial turf is being used to build a walled structure or after such a structure has been constructed.
- Preferably the binding agent is allowed to dry, harden or set prior to moving the artificial turf to another location from that where the binding agent is applied.
- In use, the binding agent bonds the granules of the infill material together so that they cannot fall out as the artificial turf is further processed, transported, stored and re-used.
- Alternatively, the process could be applied to new artificial turf once the upper surface thereof has been in-filled with the granular material.
- The binding agent may be applied by spraying, painting or otherwise wetting the granular infill material.
- The binding agent may comprise an adhesive formed of modified starch, methyl cellulose, polyvinyl acetate (PVA), or other material. The binding agent may also comprise other materials such as, for example, acrylic paint, humectant or a dying agent.
- The use of a humectant in the binding agent has the effect of retaining moisture inside the artificial turf.
- The use of a dying agent in the binding agent enables the application of color to the artificial turf which can help to delineate regions within a structure constructed using the artificial turf. This may enable color to be added to a structure or region constructed using the artificial turf, which may enable an advert or a slogan to be displayed therein. If the artificial turf is being used to construct a wall structure for a golf course bunker, the color may be chosen to match that of sand within the bunker.
- The use of an adhesive means that other material, such as sand, may be applied to form a surface of that material on the artificial turf as the presence of the adhesive will cause the other material to adhere to the artificial turf.
- The formation of a surface of a material such as sand on the artificial turf hides the material from which the artificial turf is composed which means that a structure formed from the artificial turf is less unsightly.
- Preferably the artificial turf is cut into strips or tiles following application of the binding agent.
- In order to facilitate cutting, the cutting process may be carried out before the binding agent dries, hardens or sets.
- Also in accordance of the present invention, there is provided a region of artificial turf comprising a backing substrate sheet and an upper surface formed by a plurality of artificial fibers upstanding from the backing substrate sheet, a granular infill material disposed between the fibers and a binding agent holding the granules of infill material together.

- An embodiment of the present invention will now be described by way of example only and with reference to the accompanying drawings in which:
-
FIG. 1 is a sectional view through an area of artificial turf which has been treated in accordance with an embodiment. -
FIG. 2 a is a sectional view through a walled structure comprising a plurality of layers of artificial turf in accordance with an embodiment. -
FIG. 2 b is a magnified view of region A onFIG. 2 a, according to an embodiment. - Referring to
FIG. 1 , there is shown a region ofartificial turf 10 comprising aflexible substrate sheet 11. The upper surface of theturf 10 comprises a dense array of upstandingartificial turf fibers 12, which may be arranged individually or in groups as shown. - The space between the
fibers 12 is filled with agranular infill 13. The depth of theinfill 13 is arranged as such that a significant proportion of the upper end of eachfiber 12 protrudes out of theinfill 13 to form a fibrous surface. In the example shown, the infill comprises afirst layer 13 a of sand and asecond layer 13 b ofrubber crumb material 13 b. However, the infill may comprise only one kind of infill material or a mixture of infill materials, either mixed together or arranged in separate layers. - The artificial turf is hereinbefore defined is widely used as a covering for sports fields. After a long period of use, the artificial turf becomes flattened and worn and needs to be replaced. As hereinbefore described, UK Patent No. GB2490637B discloses how used artificial turf can be recycled by cutting it into strips or tiles, which can be laid to form a side wall of a golf course bunker.
- We now describe, with reference to
FIGS. 2 a and 2 b, the construction of agolf course bunker 20 as an example of a walled structure comprising a region ofartificial turf 22 comprising layers ofartificial turf 24 treated in accordance with the present invention. -

It is clear fromFIG. 2 b that at least some of the layers ofartificial turf 24 are staggered which definessteps 32 between adjacent layers ofartificial turf 24. - It is desirable that the
granular infill 13 remains in the artificial turf when constructing such wall structures aswall 30. In order to prevent theinfill 13 from falling out of the spaces between thefibers 12 during removal, transportation, storage and re-use, the present invention provides for applying a liquidbinding agent 28 to thegranular infill 13. Thisagent 28 is applied by spraying or otherwise wetting theupper surface 34 of theartificial turf 10 prior to removal from its original location where it may be being used for another purpose, such as to form a sports field, or being stored. - Alternatively, additionally or optionally, the liquid binding
agent 28 may be applied by spraying or otherwise wetting theupper surface 34 of theartificial turf 10 as the layers ofartificial turf 24 are being laid upon one another to construct thewall 30 ofgolf course bunker 20. -
FIG. 2 b exaggerates the scale of thenozzle 26A which may be used to apply the liquid bindingagent 28 for clarity only. - The layers of
artificial turf 24 may additionally be tied together using anchor pins 40. - The binding
agent 28 penetrates at least the upper surface of theinfill 13 to hold it together and to keep it in-situ whilst the material is further processed, transported, stored and re-used. - A binding
agent 44 may also be applied to the exposededge 36 of theartificial turf 10 using anozzle 26B, the size of which is also exaggerated inFIG. 2 b. Alternatively, optionally or additionally, the bindingagent 44 applied to the exposededge 36 may be a different binding agent from the bindingagent 28 applied to theupper surface 34. - The binding
agent 44 may comprise a dying agent which can be used, when the binding agent is applied to the exposededge 36, to apply color to the exposededge 36 of the artificial turf to alter the appearance of theouter edge 36 of the layers ofartificial turf 24. - The application of binding
agent 28 and/or bindingagent 44 may be repeated to build up a layer of coverage on theupper surface 34 or the exposededge 36. After a number of applications of the bindingagent 44 thesteps 32 on the exposededge 36 may become indiscernible. - The method of processing artificial turf in this manner significantly improves the quality and quantity of used artificial turf which is suitable for re-use in forming walled structures.
