Definitions

  • the present invention relates to the field of absorbent materials, in particular used as articles of clothing or as products for domestic use and has for its object an absorbent and desorbent device.
  • the present invention has for its object to overcome these drawbacks by providing an absorbent and desorbent device permitting, on the one hand, rapid and effective absorption of all moisture, in particular of excessive perspiration or a spilling of water, and, on the other hand, rapid desorption of the accumulated moisture avoiding any mycosal formation or undesirable bacteria.
  • the absorbent and desorbent device is characterized in that it is essentially constituted by at least one microporous membrane with absorbent and desorbent properties, by at least one porous permeable covering and by at least one impermeable shock absorbing sub-layer, essentially with closed cells.
  • FIG. 1 is an exploded perspective view of a device according to the invention in the form of a shoe sole
  • FIG. 2 is a view analogous to that of FIG. 1 of a device in the form of a bathmat.
  • FIGS. 1 and 2 of the accompanying drawings show an absorbent and desorbent device which is essentially constituted by at least one micro-porous membrane 1 with absorbent and desorbent properties, by at least one porous permeable covering 2 and by at least one impermeable shock absorbing layer, essentially with closed cells.
  • micro-porous membrane with absorbent and desorbent properties 1 is permeable to all the fluids on its two surfaces.
  • a membrane 1 is preferably of micro-porous polyolefin base of the polyethylene type with ultra-high density loaded with silica, such as that disclosed in EPO 892 647.
  • This member whose porosity is greater than 60%, has a very high absorbent power and desorbs very rapidly, such that a return to the initial characteristics of the product can be obtained in less than two hours.
  • the material constituting this membrane 1 has a high absorbent capacity for shocks, thereby avoiding the effect of micro-shocks and increases the comfort during walking and the practice of sports.
  • this membrane which can be cut out very easily and which remains indeformable even after intensive use, is very easy to use, being adapted to be washed with water and soap, and takes part very effectively to guard against micosal and bacterial infections, because of the fact that the latter can grow in a much more difficult way in a dry medium than in a moist one.
  • the micro-porous membrane with absorbent and desorbent properties 1 can be provided with grooves forming channels for the evacuation of moisture.
  • the porous permeable covering 2 can be constituted, in the case of use of the device as a shoe sole, either in the form of a woven, non-woven or synthetic textile covering, this covering being provided with micro-perforations or being highly porous and having good drying properties (FIG. 1).
  • Such a porous covering 2 is essentially adapted to permit comfortable contact with the upper portion of the device and must be easily permeable to water and to air, so as to permit easy and rapid passage of liquids toward the membrane 1 and the rapid desorption of the membrane 1 disposed below this porous covering 2 .
  • the porous permeable covering 2 can preferably be constituted by a woven or non-woven cloth covering with high porosity and low capacity for the absorption of water.
  • the moisture essentially penetrate rapidly in the micro-porous membrane 1 and that during desorption, the moisture can evaporate rapidly without being retained by the covering 2 , this latter obviously being adapted to dry very rapidly.
  • the impermeable shock absorbing sub-layer 3 is preferably pierced with holes sufficiently large and numerous to permit the evacuation of the moisture from below by evaporation. According to a modified embodiment of the invention, the impermeable shock absorbing sub-layer 3 can also not be provided with holes, when the micro-porous membrane 1 is provided with grooves forming channels for the evacuation of moisture.
  • the impermeable shock absorbing sub-layer 3 can be constituted by a foam of an ethylene/vinyl acetate copolymer that is micro-perforated and of small thickness, namely of the order of 2 mm in the case of a shoe sole.
  • a foam permits simultaneously ensuring absorption of the micro-shocks during pressure on the device, for example in the course of walking, and an exchange of air with the micro-porous membrane 1 , in particular from the lower surface of the device, to promote desorption, when said device is no longer loaded.
  • the foam constituting the impermeable micro-porous sub-layer 3 has good mechanical properties of traction against tearing and abrasion, as well as good dynamic resilience properties and resistance to bending. Moreover, such a foam is of low sensitivity to aging due to air, light, ozone and heat and strongly resists the effects of cold and fire. Moreover, this foam has a good strength against liquids, such as oils, solvents, ketones, acids, gases and water.
  • the elements constituting the absorbent and desorbent device according to the invention can be assembled together in a functional sandwich by stitching or by gluing.
  • stitching In the case of stitching, the latter is carried out over all the periphery of the device with the provision of supplemental stitching lines between the peripheral stitching, along diagonals and/or transverse and/or longitudinal lines.
  • supplemental stitching lines are necessary to avoid the appearance of folds giving rise to trouble during pressure on the device, for example during walking, such that the porous permeable covering 2 would rapidly wear.
  • thermo-gluing product 4 having a mesh structure and interposed on opposite sides of the micro-porous membrane 1 , respectively between the porous covering 2 and the micro-porous membrane 1 and between this membrane 1 and the impermeable shock absorbing sub-layer 3 (FIGS. 1 and 2).
  • a gluing product is particularly available in strips deposited on a transverse support, the assembly being rolled up on spools.
  • thermo-gluing product has a mesh such that it occupies a very small portion of the total surface of the micro-porous membrane 1 and preferably about 12% of this surface, such that the capacities, on the one hand, for transmission of moisture through the permeable porous covering 2 toward the membrane 1 and, on the other hand, of evaporation of moisture from the membrane 1 through the permeable porous covering 2 , are maintained optimal.
  • This property is also usefully used to ensure the possibility of air circulation between the lower surface of the membrane 1 and the impermeable shock absorbing sub-layer 3 .
  • the absorbent and desorbent device can be present in the form of a shoe sole to be inserted in a shoe or in the form of a shoe sole integrated permanently in a shoe and constituting the first assembly or sanitary sole of the shoe.
  • the absorbent and desorbent device can be provided, by covering, by spraying or the like, with one or several layers of antibacterial and/or fungicidal agents.
  • the provision of such supplemental layers can permit responding to the severe requirements for prevention of the spreading of bacteria or mycosa, particularly in the fields of dermatology, diabetics, as concerns the sole and hotels, bath therapies, and generally speaking public places as to bathmats.
  • the device according to the invention permits responding in a particularly effective manner to the problems raised by the need for rapid absorption of moisture, particularly resulting from hypersudation.
  • This device can be reused very rapidly, and effectively, because of its power of rapid desorption which permits it returning to the initial characteristics in a very short time.
  • the device according to the invention can ensure the function of insulation, both from heat and from cold.
  • this device draws moisture to then dissipate it into the air, it is particularly useful for physiological perspiration, contrary to the local antiperspirant treatments, when it is used as a sole in an article of footwear.
  • the device according to the invention provides no favorable terrain for the development of allergies, no allergenic components entering into its construction.
  • the device permits improvement from certain trophic troubles, such as mycoses or eczemas, the factor aggravating these troubles being again permanent moisture.
  • This device is more particularly applicable in the form of a shoe sole; soles to be inserted or original soles, but it is also applicable to other fields, particularly domestic, for example for the rapid absorption of spills and for corresponding desorption, permitting prolonged use of the absorption means and not a systematic replacement of the latter with the corresponding costs of washing and drying.
