The present invention relates to artificial derno, and more particularly to knitted artificial turf.

Various systems have been developed in artificial turf, which allow you to create the surface of synthetic turf for playgrounds designed for different sports and types of recreation. One example of the artificial turf includes a system in which the main lining quilted fibers. In specific embodiments, the implementation of the use of different combinations of yarns and/or fibers.

Known surface for playgrounds, which includes a sublayer, the pile fabric similar to grass and compacted the top finishing layer containing a mixture of elastic particles in the amount of 25-95% vol. and fine sand in the amount of 5-75%. This surface for playgrounds includes complex thread, quilted beams in the lining of woven fabric for financially or asphalt pavement, compacted clay or gravel, plated roller in normal soil (see patent GB 1320868 A).

At least because of postegivaniya beams in known systems, artificial turf, among other shortcomings, there is a tendency to weakened structures, so using them in some cases may be undesirable. Many other problems and disadvantages of the known technical solutions will become obvious to those skilled in the art after comparing these known technical solutions with the present invention, described below.

Proposed artificial turf, which is not quilted beams. This artificial turf has two top threads, one of which is textured and the other is textured (high volume), the lining, which is formed by knitting the first covering yarn, the second covering yarn, petrobrazi thread and just put the threads so that the first outer thread speaks at greater length than the second outer thread, the coating on the lining to prevent, among other things, detach threads after prolonged use of artificial turf, and the underlying layer, located under the lining and both the, 25.4 mm (one inch) above the lining, with the first outer thread selected from the group consisting of nylon 6,6, nylon 6, polypropylene, polyethylene, copolymers of polyolefins, rubber after extrusion and mixtures of these materials.

The first outer thread is a tape that contains at least two elements connected by a thin segment, and a thin segment is configured to rupture during use of artificial turf for receiving at least two separate elementary filaments for each of the first top thread.

In addition, the first outer thread has a cross-section that is similar to the three oval, United by their ends, and providing a Central oval and two outer oval, with the Central oval is connected with each of the outer ovals thin segment that is configured to rupture during use of the artificial turf to obtain three separate elementary filaments on each of the first outer thread, and each of the ovals has an outer surface, each outer surface is corrugated.

The texture in the second covering yarn is a twisting, crumpling and folding of the thread itself, so that the second top thread is not what it twisted, crumpled and folded state.

In addition, the lining further comprises petrobrazi threads that are associated with the first and second outer threads for the formation of a series of nodes and the lining further comprises a right laid thread, which is used to associate a series of nodes with each other for the formation of the lining, and the lining further comprises a coating, and this coating has formed therein holes, facilitate drainage.

The filler material has a thickness approximately corresponding to the second covering yarn.

In addition, the filler material is laid on top of the lining. Artificial turf is preferably knit and textured yarn or pile have a pile height of approximately of 15.2 mm (0.6 inch), and preferably a height of at least approximately 25.4 mm (1 inch). During operation, textured pile has a height that is substantially less than the height of the textured pile, the height (textured) pile preferably at least 25% less than the height of the textured pile. Textured and textured pile yarn are connected to each other when knitting by petrobrazi thread is to feed the machine, and right stacked strands are mutually connected to a series of nodes, forming the lining of the pile threads. For additional stability the dimensions on the lining preferably applied sealing material.

Found that to obtain the turf, manufactured in accordance with the present invention, it is possible to use a knitting machine, which can contain more than 1000 needles to obtain the width of the artificial turf, comprising approximately 4,572 m (15 feet). The Assembly process is more complex than postegivanie beams. The pile thread and paleopathology thread is inserted into the knitting needle. Straight laid thread is mutually connected to the pile and petrobrazi thread through a separate feed mechanism provided for the machine. Form a loop pile fabric and cut them using the machine for longitudinal cutting. The operation is carried out finishing knitted turf, during which put a suitable sealing material to penetrate it in the contact points in the lining and to stabilize the structure. This process is usually accompanied by heat treatment, which stabilizes the fabric and condition of the pile.

Turf corresponding to the present invention, made by way of knitting. Paul is Ino includes concrete or asphalt pavement, compacted clay, gravel, a mixture of gravel with the soil, and this sublayer stack additional soil or foamed product. Textured or retexturising pile nearly the entire height of the textured pile is preferably filled with a filler material such as sand and/or rubber particles.

Various aspects of the present invention can be implemented by creating artificial turf, which includes a first outer thread, the second outer thread, right laid thread and paleopathology thread. The second covering yarn is textured, at least, to create a textured area. The node formed by linking the first covering yarn, the second covering yarn, straight laid thread and petrobrazi threads with each other. In this way form a series of nodes. When directly stacked the thread is passed, at least, between two rows of nodes and bind to retain these at least two rows of nodes from each other, is formed lining. Top lining also put the filling material.

The first outer thread speaks at greater length than the second outer thread, and the second outer thread creates a textured area at the base of the first is placed on the lining thickness, which corresponds to the second covering yarn.

The first top thread is at least 25.4 mm (one inch) above the lining, and the second outer thread creates a textured area about the size of 12.7 mm (half inch).

In addition, the right laid thread and paleorrota thread made of a material selected from the group consisting of polyester and glass fiber, the second outer thread contains nylon material, the first outer thread contains nylon material.

There are numerous variants of the material used to create the first top thread, the second covering yarn, straight laid thread and petrobrazi thread. Of specific interest are the various types of physical forms and new sensations that can be assigned to the first outer thread depending on such factors as filler, which is used for receiving the first covering yarn, and granular material, which is prepared for extrusion by using this die.

Various aspects of the present invention can also be found in the way of creating artificial turf. This method includes, but not necessarily in this order, the following steps in which: osushestvlenie long belt in combination with another tape, which was teksturirovanie, and petrobrazi thread for the formation of nodes; cut a long ribbon to create the flat top of the thread, which has a length of about 25.4 mm (one inch); form rows of nodes of the extended tape, other tape and petrobrazi thread and carry out wezwanie stacked directly thread into the ranks of the nodes to join the ranks of the nodes and create a lining for artificial turf, and this connection also leads to the fact that creates a textured area at the top of the lining and flat top thread is up from textured areas.

Granular material formed from a mixture of nylon, paints and plastics.

Long tape divided at least into two thicker parts, which are connected by at least one thin part, which is suitable for a break in the case when the flat top of the thread is subjected to mechanical stresses during operation of the artificial turf.

In addition, put the lining on the underlying layer and fill the space in the location of the second covering yarn and around the filler material that is appropriate for the intended use case IO study the drawings and the following description.

A better understanding of the invention can be achieved by consideration of the following detailed description of the drawings in conjunction with the following drawings, which show:

In Fig.1 presents a cross section of a possible artificial turf 100, which is fabricated in accordance with the present invention. Artificial turf 100 is manufactured so that it has a flat top thread 102 and textured top thread 104, which tied into the lining 106. Lining 106 described in more detail below in connection with Fig.4, but for General and supported by examples describe artificial turf 100 it should be noted that the lining 106 represents a collection of fibers that are used for involvement flat top threads 102 and textured top threads in a single element, which is used as the artificial turf 100.

Upon completion of the knitting of the artificial turf 100 flat top thread 102 and textured top thread 104 protrude upwards from the lining 106. The pad 106 is sometimes referred to by another term of similar meaning, such as “base”, but in the context of the present invention, this structural element will be called exactly pottu the pad 106 may be coated or seal (not shown), which gives artificial derno 100 enhanced stability and durability. This coating may contain at least one material of acrylic resin, polyurethane, latex, and so on, or some set of them that helps prevent unwanted separation of the flat top of the thread 102 and the textured top of the thread 104 of the artificial turf 100 in the long run.

A desirable aspect of a particular variant of the implementation described in connection with Fig.1, is that the artificial turf 100 is knitted, and is not quilted beams. Although knitting artificial turf 100 somewhat complicates the mass production of the artificial turf 100, the author of this particular variant of implementation found that the importance of knitted artificial turf 100 outweigh the disadvantages of additional complexity, which is necessary for the manufacture of artificial turf 100. Another desirable aspect of this particular variant implementation is the use of two separate strands, flat top thread 102 and the textured top of the thread 104. Knitting both threads 102 and 104 operate in a way that, ultimately, provides an implementation of each is here to change the number of needles, for example, you can use one or more needles.

Textured top thread 104 is often called the textured area, and this thread is usually shorter than the flat top of the thread (i.e., textured yarn) 102, thereby providing a preferred area in which to place sand or rubber filler to change the overall texture of the artificial turf 100 with the purpose specific application of this artificial turf 100. In one specific embodiment, the textured outer thread 104 is a composite filament having from 2 to 20 ends, preferably from 6 to 12 ends.

In one specific embodiment, the textured outer thread 104 is obtained by passing filament through a stream of water vapor, preferably up a stream of water vapor. Manufactured fiber condense, receiving the column so that the fiber is twisted, crumpled and folded. Fiber seal, receiving the column and allow the air to pass through the column in the opposite direction to cool the filament and textured top thread 104 acquires a “molecular memory” twisted, crumpled and folded state. Other signs of texturology.

In Fig.2 presents a cross section of possible tape 200, which is used to create the flat top of the thread 102, forming the artificial turf 100. As shown in the drawing, the tape 200 includes three oval part 202, 204 and 206. Each of these oval parts 202, 204 and 206 is connected to the other through the thin segments 208 and 210. Thin segment 208 connects the oval part 202 and the oval part 204, while the thin segment 210 connects the oval part 204 and the oval part 206. Thin segment 212 is depicted to demonstrate the possibility of connecting additional oval parts (not shown) to depict three oval parts 202, 204 and 206.

It should be noted that the tape 200 retexturising. Thus, the name “flat” is used when the tape is used to produce flat top of the thread 102. Flat top thread 102 is sometimes referred to as the pile, the pile yarn, basic yarn, or give it the same name, but for the purposes of the present description it is called flat top thread 102. This flat top thread 102 is made of a tape 200, which is created from the granular material by means of extrusion through the die plate.

In Fig.3 shows a view in plan of part of Phil the blood of the thread 102, which is used for artificial turf 100. Shows the parts of the die 300 is one third die, which is used for receiving the tape 200. Filler to get the tape 200 has three openings through which the granular material to make tape 200 in the form of one continuous fibers with three oval parts 202, 204 and 206. Of course, to obtain three oval parts 202, 204 and 206 need to use three part shows part of the die 300.

Shows the parts of the die 300 includes a housing 302, which forms the hole 304 for transmission of a granular material. Shows the hole 302 has a corrugated surface 308, but may have other surface types considered in this description and in connection with other drawings. Regardless of used dies, the tape 200 is not teksturirovanie and, ultimately, used to create the flat top of the thread 102. When considering the part of the die 300 is repeated twice, using small holes 305 and 306 for connection repetitive parts of the die 300 with each other and form three holes 304 for which small holes 305 and 306 are common. Thus, the tape 200 receive the n) preferably consists of a polymer or polyolefin material. For example, the granular material may consist of polyethylene, polypropylene, polytrimethylene, various copolymers, etc. Granular material may be nylon material, such as nylon 6,6. The granular material may contain various chemicals to get different textures, colors, physical properties, etc. If you spend the extrusion of granular material through the opening 304 and similar holes, connected through small holes 305 and 306 is formed, the tape 200, which is sometimes referred to as tape segmented corrugated oval (SRO) type. Small holes 305 and 306 in filiere allow you to get the tape 200, which is thin in the vicinity of the small holes that allow the adaptation of the tape to the isolation, separation or stratification to obtain numerous ends of one of the tape 200.

One continuous tape 200, which is obtained by extrusion of granular material through a die plate with three holes associated with other threads of the artificial turf 100 to create a lining 106 (which is explained in more detail in connection with Fig.4). The tape 106, when it is cut, called flat top thread 102. Tape 2 the usual cut so so she spoke at greater length than textured cover tape 104.

As described above, the thin segments 208 and 210 preferably are broken when the flat covering tape 102 is subjected to mechanical stresses, for example, when the artificial turf 100 the game is. When the break occurs, the oval part 202, 204 and 206 become separate elementary filaments. Thus, although the tape 200 wasana in artificial turf 100 as a single filament, it becomes a complex thread, i.e., thin segments 208 and 210 are separated, torn or stratified.

In General, as evidenced by shows breakage of the thin segment 212, the tape can contain different from the number three oval parts, which are connected side by side thin segments. For example, the number of oval parts can range from two to twelve, preferably from two to six. These oval pieces give rigidity, so that the flat top of the thread 102 is almost vertically after installation on the sublayer, but before adding filling material (as described in connection with Fig.5).

In Fig.4 presents a possible scheme lining 400 (such as the lining 106) for the artificial turf 100. Lining Berna 100. For example, as a “building block” for the formation of the artificial turf 100 is provided directly stacked thread 404. Flat top thread 102 and textured top thread 104 is associated with petrobrazi thread 406 to form rows of nodes 402. Paleorrota thread 406 is depicted in the form of bright loops and flat top thread 102 and textured top thread 104 (pile yarn) are depicted as dark loops. Similarly, the flat top of the thread 102 and the textured top of the thread 104, directly put the thread 404 and paleorrota thread 406 consist of various different materials and colors corresponding to the intended use of the artificial turf 100, for example, can be selected from polyester (a complex polyester), nylon, and polyolefin. As will be obvious to experts in the art after considering this specification, the above-mentioned fibers are related to education lining 400.

In Fig.5 shows a cross section of a possible artificial turf 100 and depicts the cushion 502 of foamed material and a sublayer 504. In the depicted specific embodiment, the cushion 502 of the foam material stacked on the underlayer 504 using STD is imposed soil, a mixture of gravel and soil, asphalt, concrete or other suitable materials that provide a sustainable basis. Cushion 502 of foamed material and a sublayer 504 is usually chosen in accordance with the intended use of the artificial turf 100 and is sometimes called, either individually or as a whole, the underlying layer. This underlying layer may include any number of different materials, but usually it is chosen from the group consisting of asphalt, gravel and foam pillows. Although it is not shown in the drawing, the top of the lining may be added to the filler material, the thickness of which is approximately equal to the thickness of the textured top of the thread 104 or zone. The filler material is usually sand and/or rubber particles, but can be any material suitable for the activities that are going to spend on the artificial turf 100. In any case, the material should possess elasticity and to provide the clutch with shoes with less friction, so as to avoid injury when a player falls on artificial turf or “passing” on it after the fall.

In Fig.6 presents possible knitted lining 600 artificial turf, made in the type of threads outlined in more detail in connection with Fig.1, i.e., flat top thread and textured top thread. Lining 600 artificial turf includes a series of nodes 602, which form part of the lining 600. Each node is formed by intertwining with each other petrobrazi thread 604 and at least one of the flat top of the thread and the textured top of the thread. Directly stacked thread 606 mutually connects adjacent rows of nodes 602 to each other to ensure dimensional stability. Thus, for education lining 600 artificial turf linked together four strands: flat top thread (usually nylon), textured outer thread (usually polyethylene), paleorrota thread (usually polyester) 604 and just laid thread (usually polyester) 606. Of course, each of petrobrazi thread 604 and just laid thread 606 may be made of the same or different materials, as will be clear to experts in the art after consideration of the present description.

In Fig.7A shows you the potential of the nozzle 700, which is used in the production of the artificial turf 100. Filler 700 is divided into three parts 702, 704 and 706, each of which alraune die 700 is shown holes, through conducting the extrusion of granular material. The tape, which is obtained by extrusion of granular material through the die plate such as filler 700 has the same characteristics of the cross-section that filler 700. Continue 708 and 710 provide the tape with a thin parts, which are designed to separate when use artificial turf, which contains the tape, obtained by using the die 700. Get a flat top thread has a texture that is variable according to the type of die that is selected for the extrusion, but this thread should still be considered a “textured thread”.

Filler 700 allows you to get the tape, sometimes called the “webbed wing” (“wings of a bat”).

In Fig.7B presents a view in plan of a possible variant of the die 700 different sizes. Pictured here filer 720, which includes three openings 722, 724 and 726. Openings 722, 724 and 726 are essentially identical and arranged side-by-side, connecting sequels 728 and 730. In this particular embodiment, the holes 722 and 724 are connected by a continuation of 728. Continued 728 significantly less than the continuation 708, and provides a smaller, along with the treatment of the extrusion. Similarly, holes 724 and 726 are connected by a continuation of the 730. The dimensions of the die 720 provide another version of the texture of the artificial turf.

In Fig.7C shows you the potential of the nozzle 730, which is a variant of the die represents part of the die 300, and can be used in the production of the artificial turf 100. The die plate 730 is sometimes referred to as “non-segmented diamond”, and it looks like an elongated diamond shape without sharp corners. The ends 732 and 734 modified so that opens, connecting the die 730 with another Villeroy, such as another filler 730. In addition, the die plate 730 may be combined with other types of nozzles, for example, with 720 nozzles or 700 or their parts. Numerous options of different types of nozzles that will be obvious to experts in the art after consideration of the present description.

In Fig.7D shows you the potential of the nozzle 740, which represents another variant of the die-plate 300 and can be used in the production of the artificial turf 100. The die plate 740 is often called ribbed rectangle, and it allows you to get artificial turf with a larger roughness of the surface is arranged, creating a feeling or softness or hardness of the artificial turf. For example, when the die is connected with the abandonment of a small angle between them, or in the absence of such angle, artificial turf tends to be more soft than in the case between die leave a significant angles; when receiving tape to the flat top of the thread using a Spinneret having a significant protrusions of the embossing artificial turf is not a surface, is preferred to slip. Provided other combination of nozzles that can be selected in accordance with the intended use of artificial turf.

SUBSTANCE: invention relates to grain materials with multilayer polymer coating and a method of producing said material. The method involves mixing a first thermoplastic polymer with a grainy substrate to form a mixture at temperature higher than the melting point of the first thermoplastic polymer, cooling the mixture to temperature lower than the melting point of the first thermoplastic polymer and merging the cooled mixture with a second thermoplastic polymer, where the melting point of the second thermoplastic polymer is lower than the temperature of the cooled mixture. Further, the merged mixture is cooled to temperature lower than the melting point of the second polymer. Use of polymers with low melting point in the grain material can successfully lower requirements for heating and cooling, thus reducing power consumption of the process, leading to shorter duration of the cycle. The obtained grain material is used as filler for artificial coatings.

EFFECT: grainy filler has uniform and homogeneous coating, which makes the surface of the filler soft, thereby giving excellent wear resistance, good aesthetic and tactual properties, and ensures safety for the player.
