Definitions

  • the present invention relates to an insole with excellent foot perspiration absorption capacity.
  • the insole is removable and suitable for all types of footwear, from shoes, sports shoes, protective shoes and the like.
  • the insole of the present invention is composed of a multilayer structure, at least one of the highly hygroscopic layer, which is responsible for absorbing moisture from the foot.
  • This layer (s) are incorporated between materials which impart various properties to the insole, namely mechanical strength, abrasion resistance, shock absorption, among other properties.
  • Breathable and water vapor impermeable membranes are an alternative to achieve improvements in comfort from a moisture management standpoint. They have been the target of a multitude of applications (US 2007/0204482 Al, WO 2010/113112, WO 2010/044657, US 2009/0211119 Al, US 2009/7546697 B2), particularly in footwear, where they are applied to their different components. (insole, sole, lining, ). These membranes are sometimes combined with other components such as meshes, fabrics, nonwoven and nets of different materials and structures, giving the system better performance and strength.
  • This invention differs from existing solutions by combining materials only at the insole level. Note that the invention being an insole rather than a shoe, allows the wearer to wear it on any type of shoe, resulting in a shoe with excellent moisture management property and consequently improved comfort.
  • US 2010/7661204 B2, US 2008/0115385 A1, US 2009/7543398 B2, US 2003/6665959 BI and US 1995/5452525 also state that their functionality is applied to insoles. However, the combination of materials describing, impermeable and breathable membranes, absorbent layers applied to fabrics and nonwovens is different from that described in the insole of this invention.
  • EP0713658 discloses a multilayer insole for absorbing foot perspiration.
  • This multilayer consists of an upper layer consisting of, for example, polypropylene, an intermediate layer of GORETEX and a lower layer for absorption of perspiration.
  • US2004 / 0168355 discloses a multilayer composite material for liquid absorption.
  • the material may consist of layers and the intermediate absorbent layer comprising a microporous polyolefin or silica polyethylene structure.
  • the base materials are microporous membranes where water vapor diffusion occurs.
  • the insole of the present invention is comprised of a material having a high water vapor and liquid water absorption capacity, not just condensate water vapor permeation.
  • the remaining materials used in the insole of the present invention, polymeric nets, are open materials whose The main function, among others, is to serve as mechanical support of the absorbent layer (intermediate layer).
  • This invention relates to a high water absorbing insole (steam and liquid), lasting longer than one day.
  • the developed insole consists of a multilayer structure as illustrated in Figures 1 and 2.
  • the upper (1) and lower (3) layer of the structure consists of one or more layers of polymeric fiber / yarn textile netting.
  • the intermediate layer (2) is. consisting of one or more layers of an absorbent polymeric mantle.
  • another layer which may consist of a 3D textile material. Other layers may be added and should always be placed below the absorbent polymer layer (s) so as not to introduce additional resistance to water absorption.
  • the openings of textile nets may differ.
  • the nets In the upper layer (1), which will be in contact with the wearer's stocking, the nets may have a larger opening to increase contact between the sock and the absorbent mantle.
  • the lower nets 3 may have a smaller opening to increase the abrasion resistance of the assembly and at the same time make it difficult to transfer sweat to the shoes.
  • Upper nets (1) may consist of polymeric fibers / yarns
  • (3) may consist of polymeric fibers / yarns (monofilament or multifilament) polymer with a diameter between 0.015 and 0.040 mm with decitex between 330 and 2000.
  • These nets should be made of moisture-absorbing synthetic materials that are resistant to mold and bacteria to increase their durability. These fibers must have high abrasion resistance so as not to suffer mechanical wear or tear during use. In this regard it is important that the fiber has good elasticity and good wrinkle and crease resistance.
  • polymeric materials meet these requirements, such as PVC, PVDC, PU, among others.
  • the intermediate layer of the insole (2) may consist of one or more textile substrates (woven, knitted, non-woven) impregnated with materials with high absorption capacity. These materials, commonly referred to as superabsorbents, are hydrophilic macromolecular compounds capable of absorbing large volumes of water or aqueous solutions. Superabsorbents may be produced by polymerization of acrylic acid, acrylic esters, acrylamide and other unsaturated monomers. These materials have the particularity that they can retain in their molecular structure about 100 to 1000 g of water per gram of initially dry polymer, with greater or lesser retention capacity being associated with various structural factors.
  • the insole there may be yet another layer consisting of a material like a 3D textile mesh.
  • a material like a 3D textile mesh As its name implies, it is a three-dimensional mesh composed of two types of outer textile substrates, which are joined by spacer yarns. The most commonly used yarns in this type of mesh are polyester, polyamide and Kevlar.
  • the multifunctionality This layer lies in increased wearer comfort by cushioning, shock absorption, increased wear resistance by wearing the insole, increased breathability (favors air circulation) and redistribution of pressure exerted by the wearer. It is also noteworthy that because this mesh has high resilience, that is, regain its shape after compression, it is suitable for successive and constant uses of the insole.
  • insole of this invention may be provided with an antibacterial and / or antifungal coating, spray applied, ultrasonic spray, impregnation, and the like.
  • the constituent elements of the present invention may be assembled in the form of insole by seam, (thermo) bonding, ultrasonic bonding, radio frequency bonding, hot melt lamination or flat bed, among others.
  • Sweat in the sock as a result of the user's sweating, crosses the upper layer (1), which is comprised of one or more wide open polymeric textile nets, and is quickly absorbed by the intermediate layer (2) of the insole.
  • This process results in an increase in the volume of the absorbent layer (s) (middle layer of the insole (2)) without being perceived by the user as the textile webs surrounding the Absorbent layer (s) impart dimensional stability to the multilayer structure.
  • the absorption process is perfectly reversible, so it will be enough for the user to remove the insole from the shoe for a few hours for the moisture content of the insole to return to normal values (ie those that are in equilibrium with the relative humidity of the environment the insole is exposed).
  • the present invention relates to an insole comprising a multilayer structure comprising at least one hygroscopic layer consisting of one or more textile substrates impregnated with hydrophilic macromolecular materials.
