Definitions

  • the present invention relates to synthetic (or "artificial") grass coverings.
  • Synthetic-grass coverings have been used for quite some time now, in particular to provide areas of greenery for urban decoration and similar amenities, for areas for bordering swimming-pools, and, in general, for replacing natural-grass cover in all those conditions where the laying and maintenance of a natural-grass cover may prove critical.
  • the use of said synthetic-grass coverings has received new impulse in recent times in order to provide coverings for sports facilities, for example, soccer pitches.
  • a synthetic-grass structure which comprises a sheet-like substrate with a plurality of filiform formations extending from the substrate for simulating the grassy sward of natural turf, and a particulate filling material, or infill, dispersed between the filiform formations so as to keep the filiform formations themselves in a substantially upright condition.
  • the above synthetic-grass covering is characterized in that the particulate filling material (infill) is constituted by a substantially homogeneous mass of a granular material chosen in the group constituted by polyolefin-based materials and by vinyl polymer-based materials.
  • a solution still widely used for making the aforesaid filiform formations envisages resorting to a yarn having a base of plastic material, such as polyethylene.
  • the material in question is initially laminated so as to form a sheet or web of the thickness of, for example, 200 - 300 micron.
  • the sheet is then subjected to a cutting operation, which divides the sheet into a large number of strips of small width (for example, 10 - 20 mm).
  • the cutting operation is usually followed by one or more operations of longitudinal stretching and fibrillation.
  • the web is divided into strips of given width, which are stretched and then pre-fibrillated, i.e., incisions are made in a longitudinal direction, to give rise, during normal use, to progressively thinner threads, in the direction of the width.
  • the material is gathered as a ribbon or tape on a bobbin or reel, which usually passes it on to a subsequent step of twisting of the thread, thus enabling it to be treated in the subsequent processing steps (e.g., tufting on the loom).
  • the above type of yarn is the first to have asserted itself on the market on a large scale on account of ease of production in all the steps of the process.
  • the final aesthetic appearance of the yarn is not optimal as regards reproducing the appearance of the sward of natural grass cover, but is considered acceptable by the market.
  • a practically inevitable defect in this type of yarn lies in the fact that, when four to five years have elapsed from its being laid, the corresponding coverings manifest problems of wear due to an excessive, uncontrolled and uncontrollable fragmentation during use (breaking of parts of thread, formation of very thin and brittle strips, with the possible formation of dust on account of the breaking-down/degradation of the thread, etc.).
  • An alternative technique envisages the formation of a single-thread or single-strand yarn via the formation of individual threads directly from a threading die.
  • the threads in question are stretched and gathered with four, six or eight threads per tuft, before passing on to the subsequent steps as described above (gathering, twisting, tufting).
  • This technique is increasingly asserting its presence on the market because it does not give rise to the problems of wear described above in relation to a fibrillated yarn: single-stranded yarn is not subject over time to undesirable phenomena of splitting or fragmentation.
  • the single-thread technique presents, however, various weakpoints.
  • the yarn is usually wound on reels used for supplying workstations that produce the basic structure of a synthetic-grass covering of the type described previously, i.e., with the filiform formations that extend from a sheetlike substrate.
  • Said workstations operate typically with known techniques resembling techniques of tufting or the like.
  • said techniques aim at "implanting" in a sheetlike substrate (which is either continuous or substantially continuous, for example, because it is provided with draining holes) yarn formations having a general U-shaped configuration.
  • Each formation basically constitutes a sort of tuft with a looped part that passes underneath the substrate and two lateral branches that extend vertically above the substrate, to simulate blades of grass.
  • the tuft is constituted by four, six or else eight strands or blades according to the thickness and/or width of each blade.
  • the invention also relates to a corresponding process for manufacturing said yarn, as well as a corresponding process of use for the purpose of making a synthetic-grass covering (either with or without infill).
  • the reference number 10 designates as a whole a plant that can be used for producing a yarn that is to be used for the production of synthetic-grass coverings.
  • the plant 10 is represented in the form of a set of processing stations that are here supposed as being located in a single site and designed to carry out a processing cycle comprising different operations of treatment performed in cascaded fashion one after the other.
  • a processing cycle comprising different operations of treatment performed in cascaded fashion one after the other.
  • Persons skilled in the sector will moreover appreciate that the aforesaid operations can, however, be performed in different premises or contexts and at different times, after prior storage and/or transfer of the intermediate products of the various processing steps illustrated.
  • the reference number 12 designates an extruder for plastic materials which operates with a vertical axis.
  • a plastic material in the molten state is fed into the extruder 12 through an inlet duct 14, to undergo extrusion in a threading die 16 constituted, for example, by a die with an annular profile.
  • the annular threading die 16 is constituted by a certain number of arched portions 160, separated from one another by a distance, for example of 1 - 2 cm.
  • Each portion of a threading die 160 is designed to produce a respective strip B and has the profile illustrated in Figure 2.
  • Figure 2 can be considered as a plan view from beneath of the single arched portion 160 of a threading die, as ideally viewed from beneath, i.e., from the area in which the respective strip B drops as it comes out of the threading die.
  • the single portion of a threading die 160 has a certain length (for example, 50 - 60 mm, typically 56.4 mm) measured along its arched path of extension and comprises a certain number of segments 162 (eight in number, in the example illustrated).
  • Each segment 162 has then a length (once again measured along the arched path of extension of the portion of a threading die 160 of which the segment forms part) in the region of 6.7 mm and is connected to the adjacent segments 162 (or to the adjacent segment, in the case of the two end segments 162 in the portion of a threading die 160) by a thin portion or stretch 164.
  • Each thin portion 164 has a length, for example, of 0.4 mm, and a width or thickness (dimension in the radial direction with respect to the path of extension of the portion of a threading die 160) of, for example, 0.15 mm.
  • segments 162 have a U-shaped cross section, hence one with two wider end parts or branches 1620 (once again the dimension in the radial direction with respect to the arched path of extension of the portion of a threading die 160) with respect to the central part 1622.
  • the U shape is not to be considered imperative, since the characteristic of the end parts 1620 that are wider than the central part 1622 can be achieved also with other shapes (for example, a "bone" shape).
  • the end parts 1620 can present a width or thickness (once again the dimension in the radial direction with respect to the arched path of extension of the portion of a threading die 160) of 0.67 mm as against a width or thickness of the central part 1622 of 0.46 mm.
  • each of which has, if viewed in cross section, the profile represented in Figure 3: this is, in other words, a profile complementary to the profile of the portion of a threading die 160 described previously with reference to Figure 2, hence a profile in which it is possible to distinguish a certain number (eight, in the example illustrated) of segments B1 connected to one another by slender portions B2, with each segment B1 presenting a profile (roughly U-shaped, in the example illustrated herein) with end parts that are wider than the central part.
  • the material used for forming the strips B is usually a polyolefin-based material, such as a material chosen from the group constituted by polyethylene, polypropylene and/or mixes and/or copolymers thereof, polyethylene representing the currently preferred choice.
  • the material in question is usually pigmented so as to present en masse a colouring such as typically a green colouring, it being evident that this characteristic is not to be understood as in any sense limiting the scope of the invention.
  • the strips B coming from the threading die 16 are subjected to cooling by being dipped in a cooling bath contained in a tank 18 so as to enable their consolidation.
  • each of the strips B reproduces the profile of drawing conferred upon it by the respective portion of a threading die 160, and is thus in the form of a strip constituted by a plurality of (for example, eight) filiform elements B1 (with widened ends, hence thickened with respect to the central part), set alongside one another and connected together by more slender connection portions B2.
  • each strip B tends to stretch out so that the substantial identity of shape with the portion of a threading die 160 does not usually correspond to an identity of dimensions.
  • the strip B can present a width in the region of 20 mm, with the segments B1 and the slender portions B2 that have homologous dimensions of width, respectively of 2.4 mm and 0.12 mm.
  • the dimensions of thickness can instead be approximately 300 micron and approximately 30 micron, respectively, for the segments B1 (maximum thickness in an area corresponding to the thickened ends) and for the slender portions B2.
  • the slender connection portions B2 preferably have a thickness sufficient to cause them not to be brittle in normal conditions of manipulation of the strip B, where by "normal conditions of manipulation” is meant the conditions corresponding to the fact that the strip B is gripped by a person with his hand and felt, for example, by winding it around his fingers.
  • the strip B or each strip B consolidated by cooling (the solution herein represented, which envisages the simultaneous formation of a number of strips B, constitutes only a preferred, but non-imperative, embodiment of the invention) is then to be fed into a drawing assembly, for example, with motor-driven rollers, designated as a whole by 20.
  • the strip or strips B can be taken up in the course of a process that is either continuous (and in this case there will usually be provided one drawing assembly 20 for each strip B) or else discontinuous, in this case envisaging a gradual emptying from the tank 18 of the web/strips B that gradually accumulate therein.
  • the strip or strips B (in what follows reference will be made to just one strip, for reasons of simplicity of treatment) is/are sent on to an assembly for longitudinal stretching 22.
  • this assembly is normally constituted by an oven for heating the material and two or more sets of motor-driven rollers, each comprising two counter-rotating rollers, between which the strip B is made to advance (from left to right as viewed in Figure 1) in conditions in which the peripheral or tangential speed of the pairs of rollers (hence the speed imparted upon the strip B) increases gradually.
  • the strip B is subjected, in one or more stages, to an overall action of longitudinal stretching.
  • the strip B' subjected to stretching (in what follows also referred to, for reasons of brevity, as "yarn") has a width and a thickness that are smaller than that of the starting strip B, having, however, preserved in a practically unaltered way (for well-known physical reasons) its cross-sectional profile during stretching.
  • the yarn B' deriving from stretching is obtained, if viewed in cross section as represented in Figure 3, in the form of a strip of the width of, for example, 9-10 mm constituted (as in the case of the "length" of strip B from which it has been obtained) by a plurality of filiform segments B1' set alongside one another and connected together by more slender connection portions B2', with the segments B1' that have thickened end parts.
  • the segments B1' can have a width of 1.1 - 1.3 mm and a thickness (maximum, in an area corresponding to the thickened ends) of 130 - 150 micron.
  • the slender connection portions B2' can instead typically have a width of approximately 30 micron and a thickness of 10 micron in the thinnest area.
  • the slender portions B2' are very brittle, so that the single yarn B' can be easily fibrillated, i.e., split into individual threads, each corresponding to one of the segments B1', by breaking the slender portions B2' with a modest stress such as the one deriving from the operation of twisting normally performed for winding the yarn B' onto reels R according to the modalities and for the purposes described in the introductory part of the present description.
  • the strip B' thus behaves as a true strip, with all the resulting advantages, until the operation of twisting, when the strip then divides up into the individual strands.
  • the reference number 24 indicates a processing station, which, operating according to criteria in themselves known (i.e., basically according to techniques of tufting or the like) enables formation, starting from the yarn B' wound on reels R, of a synthetic-grass covering designated as a whole by S.
  • This is basically a synthetic-grass structure S that comprises a sheetlike substrate K, from which there extends a plurality of filiform formations (constituted by the yarn B') that simulate the grassy sward of natural grass cover.
  • the weaving station 24 operates by "implanting" in the sheetlike substrate K formations each comprising a sort of tuft of yarn B' having a looped part L that passes underneath the substrate K and two lateral branches that extend vertically above the substrate K, simulating blades of grass.
  • the synthetic-grass structure S is suited to receiving (once again according to altogether known criteria) a filling with particulate material F dispersed between the filiform formations so as to keep the filiform formations themselves in a substantially upright condition.
  • the particulate filling material (infill) F in question may be constituted by a substantially homogeneous mass of a granular material chosen from the group constituted by materials with a base of polyolefin and by materials with a base of vinyl polymer.
  • the filiform formations that extend above the sheetlike substrate K instead of having their distal ends free (according to the plush or velvety configuration, represented in Figure 4) can instead be connected to one another, creating loop formations.
  • Figures 6 and 7 illustrate the appearance of a length of yarn B', respectively before and after separation of the individual segments B1' deriving from breaking of the slender portions B2' originally connecting the segments themselves. After their separation, the segments B1' preserve their individuality precisely, without undergoing further fragmentation.
  • the structure of the yarn B' means that the yarn B' itself gives rise to a plurality of filiform elements B1', the characteristics of which are defined precisely, for example, so that (according to a currently preferred, but non-imperative, embodiment) the filiform elements B1' are substantially the same as one another.
  • the solution described herein in any case prevents one of the traditional drawbacks of the operations of fibrillation, namely, the fragmentation of each blade of yarn in an irregular (in effect random) way, with the consequent formation of fibrils of different width, frequently so thin as to break up and crumble under minimum stress.
  • the solution described herein does not alter appreciably the criteria of production of the synthetic-grass covering S, in particular as regards the development of the operation of "weaving" of the synthetic-grass covering.
  • the (somewhat burdensome) operation inevitably required by single-thread techniques, namely of having to aggregate a certain number of single threads to form a tuft, is avoided.
  • the operation of separation of the segments B1' (breaking of the slender portions B2') can be performed or completed after the yarn B' has been woven with the substrate K, for example, with an operation of brushing of the synthetic-grass covering formed by the yarn B', performed, for instance, with a rotary brush that subjects the yarn B' to mechanical stress, bringing about fragmentation of the yarn itself in an area corresponding to the slender portions B2'.
