Definitions

  • the present invention relates to floor matting, more particularly matting that is suitable for use at the entrances of buildings or other locations.
  • Entrance mats are used to remove dirt and water (hereinafter referred to generally as “soil”) from the shoes of pedestrians as they enter a building.
  • soil dirt and water
  • entrance mats are also required to remove dirt and water from the wheels of trolleys or similar articles. Accordingly, reference herein to the removal of soil from the shoes of pedestrians should be considered to include the removal of soil from all traffic (pedestrian and wheeled) that passes over an entrance mat. It is recognized that an entrance mat that functions efficiently can greatly assist in the maintenance of a building by reducing the amount of cleaning that is required.
  • the owners/occupiers of buildings are increasingly demanding entrance mats that will enhance the appearance of their premises.
  • entrance mats are known and, depending on their construction and the materials from which they are formed, are placed immediately outside or inside a building. Some entrance mats are intended to be replaced frequently i.e. when they become dirty, they are simply taken up and removed for cleaning (often by washing) and a new mat is put in place. Mats of that type are often provided on a rental basis. Some entrance mats require skilled professional cleaning, which may be carried out on- or off-site; in the latter case, it is again necessary for the mats to be taken up and replaced when dirty.
  • mats are intended to be left in position for longer periods of time: they are typically harder-wearing and more-effective in removing soil from shoes, and have a greater capacity for trapping and storing the removed soil (so that it is not subsequently carried into the building) without the appearance and effectiveness of the mat being adversely affected.
  • a mat of that type can be installed in a recess well in a floor or laid directly on the floor as a drop-down mat, and may be constructed so that dirt can fall through the mat onto the underlying surface: in that way, the surface of the mat remains clean and effective on the basis of minimal maintenance, it being necessary to take up or roll back the mat only periodically so that the underlying surface can be cleaned, following which the mat can be replaced. Any water that is removed and trapped by the mat is expected, in time, to evaporate.
  • Mats generally remove soil from shoes by a scraping and/or wiping action, depending on their construction and the materials from which they are formed.
  • Mats that provide a scraper action typically have an upper, shoe-contacting, surface that comprises scraper edges or projections as described, for example, in U.S. Pat. No. 4,497,858 (Dupont and Laurent); US 2004/0161988 (Yaw); WO 01/60218 (Milliken & Company); and WO 02/15765 (Construction Specialties (UK) Ltd.).
  • Scraper mats that have proved to be both durable and effective in removing dirt from shoes etc. are available, under the trade names “NomadTM Terra 8100” and “NomadTM Terra 9100”, from 3M Company of St.
  • Mats that provide a wiping action typically have a textile upper surface: they are often more aesthetically pleasing than scraper mats, and are available in a wide range of colours and designs and with differing characteristics depending on the textile fibres and textile constructions from which they are formed.
  • mats of that type are the profile mats available, under the trade name “NomadTM Optima”, from 3M Company of St. Paul, Minn., USA.
  • Those mats comprise a plurality of parallel aluminium profiles that are linked together, each profile containing an infill of the above-mentioned “NomadTM Aqua” matting material.
  • the infill material provides a wiping and a scraping action, the latter being supplemented by the scraping action of the profiles.
  • soil removed from the soles of shoes is efficiently retained by the mat, either by the infill material or by falling between the profiles into the recess well in which the mat is installed.
  • the present invention provides matting material comprising a supporting web of comparatively coarse filaments in which is embedded a web of comparatively fine fibres, wherein the upper surface of the embedded fibrous web is a shoe-wiping surface, and the coarse filaments of the supporting web project above the upper surface of the embedded web to form shoe-scraping elements.
  • the embedded web may be embedded in the supporting web by needle-tacking.
  • the filaments of the supporting web of matting material in accordance with the invention may comprise continuous coiled filaments, which may be bonded to one another at their points of contact.
  • the embedded web may a nonwoven fibrous web.
  • comparatively coarse filaments means filaments having a linear density of not less than 100 dtex; “comparatively fine fibres” means fibres having a linear density no greater than 100 dtex
  • FIG. 1 is a perspective view of a piece of matting material in accordance with the invention
  • FIG. 2 is an enlarged diagrammatic cross-section of the matting material, on the line 2 - 2 in
  • FIG. 1 is a diagrammatic representation of FIG. 1 ;
  • FIG. 3 is an enlarged perspective view of a component of the matting material of FIGS. 1 and 2 ;
  • FIG. 4 is an enlarged perspective view of another component of the matting material of FIGS. 1 and 2 ;
  • FIG. 5 illustrates, diagrammatically, a process used to manufacture the matting material of FIGS. 1 and 2 .
  • the matting material 1 shown diagrammatically in FIGS. 1 and 2 comprises a supporting web 3 , formed from comparatively coarse filaments, in which is embedded a web 5 formed from comparatively fine fibres. Both webs will be described in greater detail below.
  • the upper surface 7 of the mat 1 is the surface that comes into contact with the shoes of pedestrians who walk over the mat when it is located at the entrance of a building, or the wheels of trolleys or similar objects that pass over the mat.
  • the upper surface 7 is intended to remove soil from those shoes, wheels etc. and prevent the soil from being carried into the building.
  • some parts 9 of the filaments 11 of the supporting web 3 project above the upper surface of the embedded web 5 .
  • Those projecting parts 9 act as scraper elements that remove soil from the shoes of pedestrians by a scraping action.
  • the embedded web 5 removes soil and water from the shoes of pedestrians by a wiping action.
  • the structure of the supporting web 3 is shown in greater detail in FIG. 3 . It is a three-dimensional structure formed from continuous, polymeric coiled filaments 11 that loop and overlap one another, and are bonded to one another at their points of contact. As described below, the supporting web 3 is structured to allow the fibrous web 5 to be embedded in it.
  • the filaments 11 of the supporting web 3 are formed from any suitable polymeric material and have a linear density of at least 100 dtex. Typically, the linear density of the filaments 11 will be in the range of from 100 dtex to 1000 dtex although, in some cases, filaments having a diameter as large as 5 mm can be used.
  • the cross-section of the filaments 11 will typically be circular, although filaments having other cross-sectional shapes (for example, elliptical, trilobal, tetralobal) can be used. Suitable materials for the filaments 11 include polypropylene, polyethylene, polyester, and polyamide.
  • the supporting web 3 will typically be comparatively open (i.e. it will typically have a comparatively high volume of void spaces), and will typically have a thickness in the range of from 4.0 to 27.0 mm (6.0 to 14.0 mm for most matting applications) and a weight in the range of from 100 to 1000 g/m 2 (200 to 500 g/m 2 for most matting applications).
  • the web 3 should also have some resilience, appropriate to its use in a matting material.
  • the web 3 may have an undulating structure, exhibiting a regular array of peaks and valleys.
  • the undulations may be present only in the upper surface of the web, or throughout its structure.
  • the peaks and valleys may be arranged in a grid pattern so that the web 3 undulates in both the longitudinal and transverse directions.
  • the undulations may be in the form of corrugations (as illustrated in FIG. 3 ) extending in either the longitudinal or the transverse direction.
  • the undulations are, however, not essential.
  • the supporting web 3 should be formed from coiled filaments.
  • the supporting web 3 could, for example, comprise cut filaments that project above the upper surface of the embedded web 5 to form shoe-scraping elements.
  • webs suitable for use as the supporting web 3 are those available, under the trade designations: “ENKAMAT” 5006-H, 5006 I, 7006 I, and 7006 H, from Colbond Geosynthetics Company of St. Denis la Plaine, 93128 France; “Fortrac 3D” from HUESKER Synthetic GmbH of Gescher, 48712 Germany; and “TENSAR MAT” from Tensar International SARL of Mérignac, 33700 France.
  • the fibrous web 5 that is embedded in the supporting web 3 is illustrated in FIG. 4 . It is a dry-laid, open, three-dimensional, semi-finished, non-bonded, non-woven web formed from staple fibres 15 in any suitable manner.
  • the fibres 15 may be formed from any suitable artificial or natural material including, for example, polyamide, polypropylene, polyethylene, and may be of any suitable length.
  • the fibres 15 will typically have a linear density in the range of from 10 to 100 dtex.
  • the weight of the web 5 will be selected having regard to the characteristics of the supporting web 3 and the required characteristics of the matting material 1 : typically, the weight of the web 5 will be in the range of from 200 to 400 g/m 2 .
  • a proportion of the fibres 15 used to form the web 5 may be crimped: generally, this will have the effect of increasing the bulk (volume per unit weight) of the web 5 , although it may also increase the raw material cost.
  • the web 5 can be formed using, for example, a conventional air-laying process or a conventional carding and cross-lapping process.
  • the cohesion of the web 5 prior to its incorporation in the supporting web 3 , is comparatively low and, for that reason, the web 5 is manufactured as part of the process for manufacturing the matting material 1 as will be described below.
  • a process for manufacturing the matting material 1 is illustrated diagrammatically in FIG. 5 .
  • the bales of fibres for the fibrous web 5 are first opened and the fibres 15 are placed on the inlet conveyor belt 20 of an opening/mixing machine 22 in which they are teased apart and mixed by rotating combs.
  • the opening/mixing machine 22 may, for example, be a “Cadette” machine commercially-available from LAROCHE S.A. of Cours la Ville, 69470 France.
  • the fibres are then blown into web-forming equipment 24 in which they are formed into the required dry-laid, open, three-dimensional non-woven web 5 .
  • a preferred type of non-woven web is one that is formed in an air-laid carding machine, in which case the web-forming equipment 24 may be a “Rando-Webber” device commercially-available from Rando Machine Co., LORD, N.Y.
  • the web-forming equipment 24 could be one that produces a dry-laid web by carding and cross-lapping, rather than by air-laying.
  • the cross-lapping may be horizontal (for example, using a “Profile Series” cross-lapper commercially-available from ASSELIN-THIBEAU of Elbeuf sur Seine, 76504 France) or vertical (for example, using the “Struto” system from the University of Liberec, Czech Republic or the “Wave-maker” system from Santex AG of Switzerland).
  • the formed web 5 is then conveyed, together with the separately-supplied supporting web 3 , to a needle tacker 26 .
  • the webs 3 , 5 are fed into the needle tacker 26 with the supporting web 3 positioned underneath the fibrous web 5 , and the two webs are needle-tacked together.
  • the fibrous web 5 is consolidated by the needle-tacking, and is pushed into the supporting web 3 as well as being joined to it.
  • the resulting matting material 1 is as shown in FIGS. 1 and 2 and described above, with the peaks 9 of the undulating upper surface of the supporting web 3 projecting above the upper surface of the consolidated web 5 .
  • the extent to which the web 5 is consolidated and pushed into the supporting web 3 can be varied by adjusting the needle-tacking process parameters (i.e. the type of needles used, the extent to which they penetrate into the combined webs, and their stroke speed). If a multi-head needle tacker is used, it should be possible to achieve the required consolidation and positioning of the web 3 in a single pass through the machine: in some cases, however, it may be necessary for the webs 3 , 5 to make more than one pass, with the orientation of the webs being reversed between passes. Some of the fibres 15 of the embedded web 5 may remain on the peaks 9 of the supporting web, but this would not normally affect the performance of the resulting material 1 .
  • Matting material 1 produced by the process illustrated in FIG. 5 is then cut to the required size to form a mat, having regard to the area in which the mat is to be installed.
  • the matting material may be laminated to a suitable backing material, for example a vinyl material which may extend beyond the cut piece of material 1 to provide a finished edging for the latter.
  • the cut piece of material 1 may be secured to a prepared base that will also provide a suitable edging.
  • the matting material can be used as an upper, removable, layer of a mat, which can be replaced as required while the base part of the mat remains in position.
  • the upper removable layer and the base part of the mat could be secured together in any appropriate manner including, for example, by providing the upper removable layer with a tacky backing (see below) or by means of a hook-and-loop reclosable fastener system.
  • a tacky backing see below
  • a hook-and-loop reclosable fastener system it may be necessary only for the hooked-component of such a fastener system to be provided on the base part of the mat for direct engagement with the upper layer.
  • An example of a disposable mat combined with a base which may be either permanent or temporary, is described in U.S. Pat. No. 4,609,580 (Rockett et al).
  • the matting material 1 is used to provide a mat that will resist slipping or being deformed (for example, buckled or stretched) by traffic passing over it when in use.
  • matting material of the required size may be provided with a backing on its lower surface that imparts those characteristics to the mat.
  • the backing material preferably, should not add substantially to the weight or thickess of the matting material 1 , and should allow the matting material to be rolled up if required.
  • One suitable type of backing material is a fibrous web of any suitable construction that has been coated with a tacky material, at least on the face directed away from the matting material 1 , to provide it with the required slip-resistance and deformation-resistance.
  • a suitable backing material of that type is 3MTM Tack Cloth material available from 3M FRANCE SA, of Cergy-Pontoise, France.
  • Other suitable backing materials are non-slip fibrous webs intended for use under mats, for example the material available under the trade designation “Allstop® Classic” from LANDOLT FRANCE SAS of Cernay, France.
  • the backing material can be attached to the matting material 1 by an adhesive, by welding, by needle-punching or in any other suitable way.
  • a backing material can be provided by first attaching a fibrous web to the matting material 1 and then applying a suitable non-slip coating to the exposed face of the fibrous web.
  • the fibrous web can be omitted and the non-slip coating applied directly to the lower face of the matting material 1 .
  • suitable coating materials include materials available under the trade designation “PRIMAL” from Rohm & Haas of Philadelphia, USA.
  • Yet another suitable backing material is a grid of rubber or similar material, which is attached directly to the lower face of the matting material.
  • the matting material 1 may be desirable to provide the matting material 1 with an impervious backing. That may not be necessary, however, if the water-retention characteristics of the matting material are already appropriate for its intended use.
  • the needle-tacker 26 could be replaced by any other apparatus capable of consolidating the fibrous web 5 and embedding it in the supporting web 3 .
  • the needle tacker 26 could be replaced by suitable hydro-entangling apparatus known for use in the production of non-woven materials.
  • the characteristics of the supporting web 3 should, of course, be selected having regard to the nature of the mechanism used to embed the fibrous web 5 .
  • a mat formed from the matting material 1 will remove soil from shoes through both a wiping and a scraping action.
  • the scraping action will be provided by the projecting portions 9 of the filaments of the supporting web 3
  • the wiping action will be provided by the upper surface of the embedded fibrous web 5 .
  • the relative effectiveness of those actions will depend not only on the characteristics of the webs but also on the extent to which the embedded fibrous web 5 is able to contact the shoes of pedestrians passing over that mat (which, in turn, can be varied by changing the depth to which the fibrous web is embedded and the resilience of the supporting web 3 ).
  • the balance between the scraping and wiping characteristics of the matting material 1 can thus be readily adjusted to suit the normal ambient conditions of the geographic area for which it is produced.
  • the wiping action provided by the fibrous web 5 can be enhanced if the matting material is intended for use in a climate in which shoes will pick up a greater amount of water, while a supporting web 3 with enhanced scraping abilities can be selected for locations in which shoes will pick up a greater amount of dirt.
  • the mat can, through an appropriate choice of starting materials, be produced comparatively cheaply, making it economically possible for the mat to be disposed of when it becomes soiled, damp, or worn.
  • the weight of the mat may be comparatively low, possibly as low as 300 g/m 2 , making it very easy to move for cleaning or replacement purposes. Nevertheless, the efficiency of the mat in removing soil from shoes can be comparable, or even superior, to that of the type of mat typically provided on a rental basis because, unlike the latter (which is usually a textile mat providing a wiping action only), it provides both a wiping and a scraping action.
  • the matting material can also be constructed to retain and store soil in such a way that the mat generally presents a clean appearance, and in such a way that the soil is not subsequently picked up and “tracked' into the interior of a building.
  • a further advantage can be obtained if the supporting web 3 and the fibrous web 5 (and any backing material) are formed from the same recyclable polymeric material (for example, polyamide or polypropylene) because the entire mat can then be recycled at the end of its useful life.
  • the backing material is advantageously readily separable from the matting material so that they can be handled individually for recycling purposes.
  • the properties of the mat can readily be enhanced, either during the manufacturing process or through a suitable choice of starting materials.
  • the durability of the fibrous web 5 can be increased if a proportion of the fibres 15 used to form the web 5 (typically up to about 60% by weight) are heat-bondable fibres that are softened by passing the matting material 1 of FIG. 5 through an oven after it has left the needle tacker 26 , to soften the heat-bondable fibres so that they bond to other fibres in the web 3 .
  • any suitable heat-bondable fibres can be used (including those of bi-component form) although, with a view to recycling a mat at the end of its useful life, the heat-bondable fibres should be formed from the same general type of recyclable polymeric material as the supporting web 3 and the other fibres of the fibrous web 5 . It is also possible to enhance the water absorption capabilities of the matting material by forming the fibrous web 5 in two layers, the upper layer being suitable for removing soil and water from the shoes of pedestrians by a wiping action, and the lower layer being capable of absorbing the removed water.
  • Suitable fibres for the lower layer are super-absorbent fibres, for example polymeric fibres that have been surface-treated so as to provide them with hydrophilic properties, and fibres made from polymeric material compounded with hydrophilic material.
  • the relative weights of the two layers can be adjusted to alter the characteristics of the matting material as required.
  • a single fibrous web as described above could be used, in which the super-absorbent fibres are mixed with the other fibres.
  • Enhancement of the mat properties can, if required, also be used to provide a cost-effective mat of “semi-disposable” quality i.e. one that can be cleaned and re-used a limited number of times. That can be achieved by, for example, using a stronger supporting web 3 and/or a heavier fibrous web 5 , and/or applying a special treatment to the matting material.
  • the material produced by the process illustrated in FIG. 5 is primarily intended for use as an entrance mat, it could be employed for mats in other locations including, for example, catering facilities, domestic kitchens, and bathroom, and in areas around beverage-dispensing machines. If the mat is used in a location in which it will be stood upon for long periods of time, the supporting web 3 can be selected to provide the mat with a higher degree of resilience to improve its “anti-fatigue” properties.
  • matting materials in accordance with the invention and processes for their manufacture, will now be described, together with the results of tests carried out to assess the performance of the matting materials.
  • Polypropylene fibres (waste or recycled from the textile industry) having a linear density in the range of from 10 to 60 dtex and a length in the range of from 40 to 90 mm, available from PROCOTEX Company of Mouscron, Belgium under the designations F1-PPESEF-0001 and Y1-PPTCCP-0060 (hereafter referred to as “F1” and “Y1” respectively).

  • a soil-trapping test in which the ability of a matting material to remove dirt from the soles of shoes is measured. Calibrated sand is used to simulate dirt and is applied in predefined amounts to the soles of specified shoes worn by pedestrians who cross a predefined length of the matting material. The amount of sand trapped in the mat is measured so that the percentage of the sand removed by the matting material can be determined The test is repeated in an identical manner for different matting materials and the results are compared.
  • a water-trapping test in which the ability of a matting material to remove water from the soles of shoes is measured. Water is applied in predefined amounts to the soles of specified shoes worn by pedestrians who cross a predefined length of the matting material.

The test is repeated in an identical manner for different matting materials and the results are compared.
  • a durability test in which the ability of a matting material to withstand wear is measured in an alternative manner.
  • a sample of the product is weighed and then subjected to abrasion by moving the sample backwards and forwards relative to the face of an abrasive disc that is resiliently-biased into contact with the surface of the sample.

  • the fibres were then blown into the carding machine which was operated with the parameters shown in the following Table 1 to produce webs of different weights (shown in the final column of the Table):
  • Each fibrous web was then conveyed, with coiled web, to the needle tacker which was operated with the parameters shown in the following Table 2 to consolidate the fibrous web and embed it in the coiled web. Three passes through the needle tacker were required, with the orientation of the webs being reversed between passes.

  • samples 2 and 4 showed comparable performance to the textile mat, all being superior to samples 1 and 3.
  • Samples 1 to 4 also offered, in addition to the environmental advantage of utilizing waste/recycled fibres for the embedded air-laid web, the further environmental advantage of being recyclable at the end of their useful lives.
  • Sample 5 a material in which the embedded fibrous web comprised a mixture of Y1 fibres (33.3% by weight), IFF fibres (33.3% by weight) and ES fibres (33.3% by weight).
  • the material was passed through the oven (not shown in FIG. 5 ), which was set at a temperature of 145° C.
