Definitions

  • the present invention relates to a self-adhesive reinforcing material and, more particularly, to a self-adhesive reinforcing material suitable for use at the heel or toe end of footwear in order to provide reinforcement and shape definition.
  • the components can be preformed moulded plastic elements but it will be appreciated that individual sizing of these pre-moulded elements will therefore be necessary.
  • the most popular form of reinforcing component for footwear comprises a component cut from a sheet of material and then, during the manufacturing process, moulded to the desired shape. This moulding procedure generally involves heating and then chilling so the reinforcing component is thermo-formable and generally a thermoplastic.
  • US Patent No. 4594283 describes a shoe making material which comprises a laminate of two webs having different apparent densities.
  • One web has an apparent density lower than 0.4 g/cm 3 and the other web has an apparent density higher than 0.3 g/cm 3 , with their difference being greater than 0.1 g/cm 3 , preferably greater than 0.3 g/cm 3 .
  • the laminate has a weight of 200 to 1500 g/cm 3 .
  • the shoe making material of such structure has a soft face layer which provides cushioning properties and a hard core layer which keeps the shape of a shoe. Because of this unique structure it permits moisture to pass through and dry rapidly. Thus it keeps the shoes in good sanitary condition and makes shoes more functional.
  • UK Patent Application No. GB 2110990 discloses a shoe stiffening material comprising a reinforcing fabric layer of a stitch bonded or needle punched non-woven fabric and a layer of a porous tissue having a pore size substantially smaller than the stitch or needle holes in the reinforcing fabric layer, the reinforcing layer being impregnated with and laminated to and a tissue by a thermoformable polymer compound.
  • a tissue layer may be laminated to each surface of the reinforcing fabric layer.
  • footwear reinforcing materials are based on fabric impregnated with a low softening point binder, or can comprise simple extrusions of thermoplastics, or be reinforced or filler loaded material. It will be appreciated that reinforced or filler loaded materials are generally cheaper as the thermoplastic is the most expensive constituent. These reinforced or filler loaded materials can be made by a variety of techniques including powder deposition where, as will be appreciated from the name, component powders of the various components are mixed and deposited upon a release paper where subsequent heating of these components melts the thermoplastic in order to consolidate these constituents together and so form the desired footwear reinforcing sheet material.
  • Impregnation does not easily allow the use of self-adhesive binders and extrusion or powder scattering do not easily allow the incorporation of long staple length fibre reinforcing materials.
  • staple fibre for example from 20mm to 100mm in length
  • thermoplastic sheet materials for example from thermoplastic sheet materials
  • a reinforcing material suitable for use in footwear stiffeners characterised in that the reinforcing material is self-adhesive and comprises consolidated melt-spun fibres of adhesive fibres having a softening point between 45°C and 70°C combined with bulk fibres having a softening point of at least 100°C in a ratio of adhesive fibres to bulk fibres between 20:80 and 80:20 by weight, said fibres having been consolidated under pressure and heat having first been entangled, wherein the adhesive fibres comprise a linear-saturated polyester, polycaprolactone or polytetramethylene adipate.
  • the adhesive fibres have a dual function in a material in accordance with the invention, in that they act as a binder material assisting in binding the bulk fibres together in the consolidated material and contributing substantially to the stiffness of the material but also provide a hot-melt adhesive by which the reinforcing material is bonded to other shoe components in use of the reinforcing material in the manufacture of a shoe.
  • the materials of the present invention are self-adhesive in that the materials will stick firmly to other shoe upper components under heat and pressure
  • an additional adhesive coating (or coatings) of hot-melt or other adhesive types may be applied if desired.
  • the adhesive from which the melt-spun adhesive fibres are formed is, for example ESTERPOWTM1112AF or ESTERPOWTM 1108AF which comprises polytetramethylene adipate and which is supplied by Bostik Limited, Sheffield, England.
  • the bulk fibres are synthetic polymeric textile fibres, suitably polyester or polypropylene (melting point about 165°C) but are generally unaffected in a material sense by the heat' and pressure applied to consolidate the reinforcing material.
  • the bulk-fibres have a softening point of at least 100°C, preferably more than 105°C.
  • the bulk fibres are from 20mm to 100 mm in length, preferably over 25mm in length.
  • the reinforcing material may have variable performances in different zones of the material, through, across and/or along its length by incorporation of differing proportions of melt-spun fibres.
  • the melt-spun adhesive staple fibres suitably could have a decitex of 0.8 to 17, more preferably 1-10, and the bulk fibres may have a similar specification. However, 1-7 decitex is preferred.
  • One method of making a reinforcing material suitable for use in footwear stiffeners comprises, at least, the following steps:-
  • adhesive polymers which become molten and sticky at about 60°C but are hard and stiff when cooled below 50°C, are used to provide the adhesive fibres.
  • Such adhesive polymers have been utilised previously as self-adhesive binders in shoe stiffener materials.
  • These adhesive polymers are melt-spun to create staple fibres.
  • the technique of forming staple fibres by melt spinning is well known and the decitex of those fibres is determined by the spinneret used.
  • the melt-spun fibres will have a length of 50 millimetres, but may range between 20 and 100mm in length.
  • melt-spun adhesive fibres are blended with normal bulk fibres made from for example polyester, polypropylene or other synthetic or man-made fibres. These bulk fibres do not melt at such low temperatures.
  • the melt-spun adhesive staple fibres and the bulk fibres are blended together and entangled using known techniques to form a non-woven fabric.
  • the non-woven fabric is heated and pressed to fully melt the melt-spun adhesive polymer staple fibres and so consolidate the bulk and melt-spun fibres together to form a continuous film of adhesive polymer within which the embedded fibrous entangled reinforcing structure formed by the bulk fibres is blended.
  • the present fibre reinforced, self-adhesive polymer film used as a reinforcing material suitable for footwear stiffeners, has very desirable attributes. It will be appreciated by those skilled in the art that the resulting reinforcing material is both tougher and more resilient than previous sintered powder deposition type reinforcing material. Furthermore, the resultant reinforcing material in accordance with the present invention is generally lighter, less dense and more economical than previous extruded filled, i.e. fibrous or particulate filler.
  • Examples of adhesive polymers suitable for the present invention are supplied by Bostik Limited of Leicester, England under the brand names ESTERPOWTM 1112AF and ESTERPOWTM 1108AF. Both these adhesive polymers are polyester based hot-melt binder/adhesive and are supplied in a free-flowing powder form. Distinctive features of these example polymers are their relatively low fusion temperature and their ability to set in approximately 4-7 minutes, after heating above their softening point, into a rigid and tough film. Both are based on linear saturated polyester namely poly(tetramethylene adipate) and are typically supplied in a particle distribution size of 100-800 microns. However, it will be appreciated that this adhesive polymer is heated until molten and then spun to create the staple fibres necessary in accordance with the present invention. These fibres will typically have a length of 50 millimetres.
  • the fibres may have a decitex between 0.8 and 17 but 1 to 7 is preferred. Generally, the coarser the bulk fibres, the more reinforcement there will be to the reinforcing material.
  • the bulk fibres may be any fibre type that does not melt or materially alter its performance through heating to the relatively low temperatures necessary to melt the polymer adhesive fibres as described above.
  • polyester and polypropylene textile fibres may be used. These fibres may be relatively coarse compared to the melt-spun staple adhesive polymer fibres.
  • the essential feature of the bulk fibres is to provide reinforcement within the adhesive polymer film. In such circumstances, coarse bulk fibres will cause greater voids and greater reinforcing material whilst finer bulk fibres may have less voids but also reduced reinforcement.
  • the non-woven fabric is made by cross-laying or lapping several webs of carded fibres to form a batt. Normally this cross-laying is a continuous process but "insert" webs including melt-blown fibres can be introduced into a wholly bulk fibre batt, or a wholly bulk fibre web insert into a mixed staple spun-melted adhesive fibre/bulk fibre batt, can be achieved. Thus, selective performance can be introduced into the reinforcing web by such web inserts.
  • the inserts may be stacked or discontinuous across (laterally) and/or along (longitudinally) the direction of reinforcing material manufacture. Such selective variation in the amount of spun-melt fibre across, through and along the reinforcing material may allow introduction of directional properties to the reinforcing material or a reduction in the proportion of such expensive fibres within the material whilst maintaining appropriate performance.
  • a further method of making a reinforcing material suitable for use in shoe stiffeners comprises at least the following steps:-
  • melt-spun adhesive web is intimately blended with a bulk fibre web as follows:
  • Example I the bulk fibre web is a polyester fibre produced by Hoechst of 1.7 decitex x 38mm nominal staple fibre length at a density of 25 gsm (grams per square metre).
  • Example II the bulk fibre web is Hoechst polyester fibre of 6.7 decitex x 60mm nominal staple length at 35 gsm.
  • DLC means 'Dead Load Collapse' - this is a typically mouldability and stiffness test for footwear toe-puffs and counters reinforcing materials.
  • 'Frank Stiffness' indicates a known flexural modulus test "Karl Frank Stiffness Test”.
  • AL indicates measurements taken in the lengthwise direction of the material.
  • AX indicates transverse measurement.
  • Another method is to melt-spin the adhesive polymer to create staple fibre as with commodity thermoplastic fibres.
  • the two types (or more) of staple fibre can then be blended and formed into web using standard carding techniques. This produces a more intimate blend of the fibres than laying up separate webs.
  • a heating and pressing process is required to consolidate the material into sheet form for use as a stiffener.
  • Example II Fibre 1.7 decitex 6.7 decitex melt-spun fibre web-weight 50 gsm 50 gsm bulk fibre web weight 25 gsm 35 gsm No of layers of each web 8 8 NPD 145 145 Pressing conditions 140°C/90 kgm (5psi) /10 secs 140°C/ 90 kgm (5 psi)/10 secs Total weight 600gsm 618gsm Total gauge 0.60mm 0.80mm Density g/cc 1.00 0.773 Bond to AQUILINETM 14.5 18.2 DLC 1 st 1.35 1.81 10 th 1.28 kg (2.831bs) 1.54 kg (3.241bs) resilience % 95 .
  • the illustrative materials can be used to provide self-adhesive counter materials which soften and become sticky (for bonding to other shoe upper components) at typical backpart moulding temperatures in shoe manufacture but nevertheless maintain a certain level of strength and minimal melt squabbing ("squabbing" is the tendency of a sheet material to spread and increase in area when subject to pressure and/or heat).
  • the illustrative reinforcing materials provide sufficient stiffness and strength when at ambient temperatures to provide adequate counter stiffener materials for use in some types of shoe.
  • the illustrative materials were made by pressing in a platen press, otherwise similar materials in accordance with the invention may be made by pressing using heated calendar rolls. Furthermore, the layers of melt-spun and bulk fibres may be assembled by cross-lapping techniques prior to needle punching, for convenient continuous production.
  • a melt-spun web may be cast, as it is manufactured, directly onto a carded (or other lightweight) bulk fibre web so that it adheres (lightly) thereto before cross-lapping or other batt formation techniques are employed.
  • the assembly ie the light weight bulk fibre web carrying the melt-spun web is then formed into a batt made up of alternate bulk fibre and melt-spun fibre layers by cross-lapping (or other suitable techniques) and the so-formed batt needle-punched and heated and pressed to consolidate it and form a further reinforcing material embodying the invention.
