Definitions

  • the present invention relates to a composite synthetic fibre material in the form of a sheet or a strip intended for use in the footwear field and, more particularly, for the production of insoles for footwear.
  • the invention also relates to a method for the production of this composite synthetic fibre material.
  • the insole of a piece of footwear performs both the function of supporting the sole that is applied to its lower face and the function of supporting the foot by means of its upper contact surface.
  • This important component of a shoe must therefore have characteristics such as to facilitate the assembly of the shoe and, at the same time, to assure good comfort for the foot.
  • the insole has to be characterized by sufficient rigidity and by resistance to abrasion, tearing and gluing.
  • materials most widely used for the manufacture of insoles for glued or assembled shoes are leather, regenerated leather and impregnated vegetable fibres, which are used to produce the so-called cellulose insole.
  • Impregnated vegetable fibres are the most widely used materials in the footwear industry for insole production on account of its low cost.
  • This material is constituted by a structure of cellulose fibres and latex and is produced by mixing the cellulose fibers with latex to form a paste that is subsequently dried and transformed into sheets so as to make it sufficiently stiff.
  • the material obtained in this way has a relatively high density and is sufficiently stiff for being used in the production of insoles for footwear; on the other hand, since latex becomes coagulated in the course of the production process, the material does not permit transpiration to take place and does not therefore assure sufficient comfort for the foot.
  • the type of cellulose material currently most widely used for the production of insoles gives rise to some problems during the actual wearing of the shoe, because it tends to flake under the effect of the sweat produced by the foot and the bending to which the shoe becomes subjected during use. Given its structure, which is similar to cardboard, it also tends to lose consistency and to become macerated when it comes into contact with water or is placed for a long time in a humid environment, which is very liable to happen during the footwear use. Consequently, according to the current state of the art, there does not exist a material for glued or assembled shoes that is capable of assuring the mechanical characteristics of the cellulose insole combined with a sufficient transpiration capacity and resistance to abrasion and sweating.
  • nonwoven fabrics which, as is well known, are formed from a web of fibres by means of needle punching and subsequent finishing treatment with chemical products.
  • a particular object of the present invention is to make available a composite synthetic fibre material in the form of sheets or strip that can advantageously be used in the footwear industry for the manufacture of footwear insoles.
  • Another object of the present invention is to provide a process for the production of a composite synthetic fibre material in the form of sheets or strips that can be used in the footwear industry for the production of footwear insoles.
  • Yet another object of the present invention is to provide a production process of the aforementioned type that will make it possible to obtain sheets of said material characterized by the absence of surface fluff on at least one face and by adequate rigidity to permit its being used for the production of footwear insoles, though without thereby negatively affecting its transpiration properties.
  • the essential feature of the method for producing a composite fibre material used to manufacture footwear insoles in accordance with the present invention consists in that the fibre web, mechanically cohered by needle punching, is subjected to a controlled surface heat treatment on at least one of its sides capable of causing the fluffy part present thereon to melt and to form semi-molten clots thereon without affecting the whole mass of the web, and thereafter is subjected to a finishing treatment in a bath containing an aqueous suspension of a synthetic rubber, and possibly is dried in a hot air furnace. Simultaneous control of the heat flow and the speed at which the web is moved makes it possible to eliminate the fluff without creating molten zones that could limit the transpiration properties and to avoid excessive web heating, which would otherwise tend to shrink and to form folds and defects.
  • the nonwoven fabric web may be made either from common synthetic fibres or from recycled fibres, for example, the polyester fibres obtained from the plastic bottles disposal.
  • the composite material obtained with the process according to the invention can represent not only an alternative to the cellulose material currently employed for the production of soles in footwear, but, thanks to its structure, also exhibits significantly improved properties, such as better transpiration, greater elasticity and resistance to bending stress, a high capacity for absorbing and desorbing humidity (sweat), dimensional stability when dry and, above all, when wet, absence of flaking, and quick diffusion, by capillarity, of the humidity generated at isolated points over the entire mass of the insole.
  • the insole made with the material according to the invention therefore, has a smooth and slippery surface that makes the use of a lining unnecessary and gives a feeling of freshness to the touch.
  • the process according to the invention is based on the use of synthetic fibres, such as polyester, polyamide and acrylic fibres either by themselves or in mixtures, received in bales 2a that are subjected to a preparatory treatment, indicated by the reference number 1, consisting of their being processed in a machine known as "bale opener" 2 and serves to homogenize the lot as regards colour and type of fibre (denier, length, volume, composition).
  • This step also envisages the addition of any antistatic additives necessary for the subsequent processing steps.
  • a first and very rough opening of the fibre masses, made compact due to a long storage within the bales, is carried out in a carding machine 3, where the fibres are parallelized until they form a web of homogeneous weight and thickness.
  • the carded webs obtained in this way are then superposed in a layering machine 4 to produce a fibrous or felt mattress of the desired weight as a function of the final weight.
  • This semi-finished product is then sent to the needle punching station, indicated by the reference number 5, comprising a series of needle punching machines 6 that, by the action of a plurality of needles in fast alternating motion in the direction at right angles to the direction in which the fibrous mattress is being fed, capture the fibres and drag them through the fibrous mass, which thus becomes bound and compacted.
  • the needle punching station comprising a series of needle punching machines 6 that, by the action of a plurality of needles in fast alternating motion in the direction at right angles to the direction in which the fibrous mattress is being fed, capture the fibres and drag them through the fibrous mass, which thus becomes bound and compacted.
  • the semi-finished product appears as a felt that is rolled up and sent to a smoothing station, indicated by 7, for the removal of the surface fluff.
  • the semi-finished product is unrolled by a first reel 8 and transported over guide rollers 9 and a working roller 10 to a linear burner 11, which serves to melt the fluff present on the surface of the product and thus to eliminate it.
  • a linear burner 11 which serves to melt the fluff present on the surface of the product and thus to eliminate it.
  • the semi-finished product is subjected to a rolling action by means of pressure roller 12, which rotates in the direction opposite to roller 10, in order to crush the partially molten clots that would otherwise render the surface bristly.
  • pressure roller 12 With a view to making sure that the rolling action is performed while the clots are still partially molten, it is important that the roller 12 should be placed at a minimum distance from the burner 11.
  • the semi-finished product thus obtained is then sent to a finishing unit 15, where it is processed to reach the desired mechanical strength.
  • a processing bath 16 constituted by a synthetic rubber (SBR, acrylic or vinylic rubber) in aqueous suspension in a mixture containing also mineral fillers and various additives, applied by means of a foulard impregnation and/or scraper spreading and/or plating.
  • SBR synthetic rubber
  • the product is passed through an hot air furnace 17 to remove the entrained water and to make it stiff and coherent.
  • the material is rolled into coils or cut into sheets, indicated by F, and then stacked.
  • the processing bath has the following weight percent composition: Styrene/butadiene latex 10-80% Calcium carbonate 5-70% Water 0-20% Acrylic thickener 0-2.5%
  • a particularly preferred composition of the processing bath according to the invention is as follows: Styrene/butadiene latex 30% Calcium carbonate 58% Water 11% Acrylic thickener 1%
  • the thickener is added to obtain the viscosity necessary to maintain the mineral filler in suspension and apply the correct quantity of bath to the textile product.
  • Mineral fillers that should preferably be present in the processing bath are calcium carbonate, kaolin and similar materials. They have the purpose of:
  • dispersing agents generally, sodium hexametaphosphate, used for dispersing the mineral filler to avoid its coagulation and therefore instability of the impregnation bath with consequent irregular weight, rigidity and appearance of the finished product.
  • the transpiration characteristics of the raw textile are maintained also in the finished product, because during the process of improving its cohesion the impregnation bath provides it with a kind of gluing between the fibres at the points in which they already adhere to each other due to the effects of the needle punching process.
  • the spaces between the fibres in the raw needle-punched state are maintained, because, during the drying step, the bath tends to adhere to the fibres at their points of contact, leaving free the zones in which the fibres are distant from each other.
  • the operating conditions in which the heat treatment for melting the surface fluff of the product is carried out are particularly important. Obviously, the contact time with the flame must be sufficient to cause the melting of the fluff present on the surface, but it must also avoid heating the bulk of the product, which, as already explained, would cause shrinkage and formation of folds. In this connection it is particularly important to control the feed rate of the product along the working roller 10, this feed rate being in any case related to the flame power of the linear burner 11.
  • the optimal feed rate that permits correct melting of the surface fibres, avoiding the formation of a completely molten surface is comprised between 30 and 80 m/min.
  • the composite material that can be obtained by means of the process in accordance with the invention has the following technical specification: Fibre weight 150/1000 g/m2 Weight of applied compound 500/1800 g/m2 Final weight 600/4000 g/m2 Thickness 0.5/5 mm
  • polyester fibre is the preferred fibre for the purposes of the present invention.
