Definitions
- the invention relates to a shoe insole made from binder-containing nonwoven fabric with embedded compact microspheres.
- the shoe insole is an important part of a shoe.
- the outsole and the shoe upper are attached to the insole. It rarely consists of leather, usually a binder-strengthened cellulose or nonwoven material, to which the outsole is attached by sewing, stapling or gluing. Above all, the process of molding on or foaming the outsole made of plastics is used. Especially for leisure and sports shoes, very light shoe insoles are required, which have to be foam and splash-proof.
- insole materials would have to have two and a half to three times the density, equivalent to up to three times the basis weight, in order to ensure that they are splash-proof and foam-tight.
- the publication DE 3231971 describes the production of an insole made of nonwoven, into which thermoplastic hollow microspheres are introduced.
- the object of the invention is to produce a shoe insole that is very light, highly flexible, low-stretch, above all splash-proof, foam-proof and does not have the disadvantages of the prior art.
- a shoe insole made of binder-containing nonwoven fabric with embedded microspheres, the microspheres of which are compact and which are embedded in the binder-containing nonwoven fabric in such an amount that the shoe insole becomes impermeable to foamed or sprayed-on plastic.
- compact microspheres with a diameter of 0.040 mm to 0.500 mm are used. According to a particularly preferred embodiment, however, much more compact microspheres with a diameter smaller by three powers of ten, namely in the range from 5 to 15 nanometers, can be used.
- the amount of hollow microspheres used is chosen so that the insole is completely sealed when molded or foamed with plastics for fastening the outsole is achieved on the insole of the shoe. Depending on the ball material, amounts of 2 to 20% by weight, based on the nonwoven containing binder, are generally sufficient for this.
- the nonwoven fabric known per se can consist of synthetic natural and regenerated fibers, with polyester fibers being preferred.
- the fiber content of the nonwoven containing binders is advantageously in the range from 30 to 60% by weight.
- a fabric advantageously serves as the basis for the nonwoven.
- the nonwoven is usually mechanically connected to this base by needling.
- a polypropylene tape fabric advantageously serves as a nonwoven underlay. The fabric causes little stretching, which has a positive effect on the shape stability and processing of the insole.
- microspheres preferably consist of inorganic material, which can be of synthetic or natural origin.
- Preferred examples are micro glass balls which have a diameter of 0.04-0.08 mm.
- Silicon dioxide with a density of 1.0 to 1.2 g / cm3 has proven to be particularly advantageous for the microspheres with diameters in the nanometer range.
- Metal oxides or their mixtures and water-insoluble organic or inorganic salts are also suitable.
- the compact microspheres are introduced into the interstices of the nonwoven fabric by means of the binder, which consists, for example, of latices based on acrylic acid esters, acrylonitrile butadiene, styrene butadiene or their mixtures.
- the binder is usually attached to the Fiber crossing points and not in the cavities of the nonwoven fabric surrounded by fibers.
- the microspheres lie in the cavities of the nonwoven and, like the fiber crossing points, form additional anchoring points for the binder.
- a kind of sail is stretched, which consist of latex and seal the insole to such an extent that the air permeability is less than 61 l / m2 / sec and the insole is foam-proof, splash-proof.
- the cavities newly formed by the sails now smaller, also provide cold and heat insulation, low density and thus low weight and high flexibility with the appropriate binder.
- Micro glass balls are available from Potters-Ballotini, based in Kirchheim-Boelen, under the brand name Ballotini micro glass balls.
- Spherical silicon dioxide with a diameter in the range from 5 to 50 nanometers and a density from 1.0 to 1.2 g / cm3 is commercially available under the brand name AEROSIL, manufacturer DEGUSSA.
- microspheres compared to the hollow microspheres described in the published patent application DE 3231971 can be found in the price and the processing. They are up to 12.5 times cheaper and have a lower temperature when processed sensitive.
- Bactericidal agents are introduced into the insole via the binder or the fibers.
- Moisture-absorbing agents in the insole ensure good climatic conditions in the liner. These conditions are achieved through the hydrophilic binder and the incorporation of cellulose fibers into the nonwoven.
- the shoe insole (1) consists of a needle fleece (2), which is needled onto a polypropylene ribbon fabric (3).
- the microspheres are first added to an aqueous NBR or SBR latex by stirring.
- the nonwoven fabric is then impregnated with the mixture of binder and microspheres, dried and vulcanized.
- the micro-glass balls with a diameter of 0.04 - 0.08 mm (4) remain in the spaces between the nonwovens and form additional anchoring points with the binder (5).
- Reference number (6) shows an enlarged area of the fleece (2).
- micro glass balls (4) are made of silicon dioxide with a grain size of 10 to 20 nanometers is stored together with binder.
- the SiO2 combines with the binder by being suspended (NBR or SBR latex) to form a film-like composite, so that no air permeability can be measured at a water column of 20 mm.
- the low density of SiO2 results in a lower weight of the shoe insole.
