Abstract

The invention relates to an embodiment for hybrid-turf bottom fibers that enables growth of roots and leaves of the natural grass between the synthetic turf yarns by applying an organic and/or inorganic filler between the synthetic turf yarns where the grass seeds can grow. In particular, the invention relates to an embodiment for hybrid-turf bottom fibers that allows the zones where the grass seeds will grow to be more porous and stronger attachment of the synthetic yarns, and that facilitate growth of the grass roots into farther depths.

Description

HYBRID-TURF MAT

Technical field of the invention:

The invention relates to an embodiment for hybrid-turf bottom fibers that enables growth of roots and leaves of the natural grass between the synthetic turf yarns by applying an organic and/or inorganic filler between the synthetic turf yarns where the grass seeds can grow.

In particular, the invention relates to an embodiment for hybrid-turf bottom fibers that allows the zones where the grass seeds will grow to be more porous and stronger attachment of the synthetic yarns, and that facilitate growth of the grass roots into farther depths.

State of the art : Today, the turf grounds are used at the football fields, rugby, American football, golf, baseball and various park and garden areas. New advancements are implemented in this field due to demanding and costly maintenance practices for such grounds. The most frequently applied advancement in this respect is the hybrid turfs.

The hybrid-turfs comprise of the combination of natural grass with the synthetic fibers, thus allowing the roots to intertwine with the artificial turf while the natural grass grows. There are different systems and methods for planting the hybrid-turf.

One of such systems is the ramming system (where the turf yarns are rammed on the existing natural grass ground) and another system is the "Woven" or "Tufted" system (where the grass seeds are planted into the carpet, allowing the growth of natural grass within synthetic turf carpet) . In time, it is observed that the hybrid-turfs bring along various problems.

In the tufted system, the grass seeds are spread within the carpets and then soil is laid thereon, thus allowing the grass seeds to germinate and take root downwards. The most significant problem here is the porous structure of the carpet backing. The structure of the carpet backing used in the state of the art prevents growth of the grass roots due to inadequacy of its pores. Another problem experienced is that the system with scarce pores stick to the parts of the maintenance machine and cause disruption of the field surface during a maintenance operation so-called "Vertidrain" . Or, in case the bottom fibers have wider pores, the pile adhesion forces of the synthetic turf yarns have lower values, thus leading to low adhesion forces for the synthetic yarns.

In conclusion, there is a necessity to make an improvement in the respective art due to aforementioned disadvantages and due to inadequacy of the existing solutions in this respect.

Objective of the invention:

The foremost objective of the invention is to allow growth of roots and leaves of the natural grass between synthetic turf yarns by applying an organic and/or inorganic filler between the synthetic turf yarns.

Another major objective of the invention is to provide protection against all probable impacts acting on the turf by supporting the natural grass with the synthetic turf yarns and the bottom fibers during use after the grass grows. Another objective of the invention is to ensure more strong adhesion of the synthetic yarns and to allow growth of the grass roots to farther depths due to extremely tight zones woven with the bottom fibers but allowing the zones where the grass seeds will grow to be more porous.

Yet another objective of the invention is to create an environment where the roots of the natural grass will grow into farther depths by establishing a more porous structure at the sites other than the sections to be in contact with the synthetic turf yarns by means of more porous bottom fibers manufactured in compliance with the weaving width.

Another objective of the invention is to prevent disruption of the field surface due to sticking to the parts of the maintenance machine during the maintenance operation by means of an alternate porous structure.

The structural and characteristic features and all advantages of the invention shall be comprehended more clearly by virtue of the figures provided hereunder and the detailed description provided with reference to such figures, and therefore assessment should be made taking said figures and detailed description into account.

Description of the Invention:

An environment where the roots of the natural grass will grow into farther depths is created by establishing a more porous structure at the sites other than the sections to be in contact with the synthetic turf fiber (130) yarns by means of more porous hybrid-turf bottom fibers (100) manufactured in compliance with the weaving width. The fact that the zones woven with the hybrid-turf bottom fibers (100) are very tightly weaved and that the zones where the grass seeds will grow have more porous structure not only ensures stronger adhesion to the synthetic turf fibers (130) but also enables growth of grass roots into farther depths. The hybrid-turf bottom (100) of the invention comprises the elements of the natural grass pore (110) that allows growth of natural grass between the synthetic turf fibers (130) by applying an organic and/or inorganic filler between the synthetic turf fibers (130) where the grass seeds can grow; a synthetic turf weaving zone (120) woven tighter than the natural grass pore (110) ; and the synthetic turf fiber (130) woven with the "Tufting method".

The hybrid-turf bottom fibers (100) are made of monofilament and/or Fibril, polyethylene and/or polypropylene yarns, that is woven as porous at the sites other than the sites corresponding to the ends of the needle intervals of the tufting machinery when compared to the other sites and/or woven by employing the tufting method using the polyethylene and/or polypropylene synthetic turf yarns on the occasionally supported bottom fibers and then manufactured by coating of the product partially or completely with latex or polyurethane or similar adhesive in order to securely fix the product to the synthetic turf fibers (130) .

The roots of the natural grass plant grow either downwards and/or laterally from the natural grass pores (110) by virtue of the more porous structure at the natural grass pore (110) zones outside the sections where the synthetic turf fibers (130) of the hybrid-turf bottom fibers (100) of the invention are woven. In this manner, a porous structure that would allow growth, and ensure supporting, of the roots of the natural grass plant is created. On the other hand, the synthetic turf fibers (130) woven on said hybrid-turf bottom fibers (100) by employing the tufting method allows attachment of the leaves of the natural grass plant to such yarns for its lifespan and remain protected.
