内底に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an inner sole of a shoe made of an indestructible material containing a binder, in which hard microspheres, that is, rigid small balls are incorporated. It is.
［従来の技術］
内底（インナーソール）は靴の重要な部分である。内底
には靴の上部分と外底（アウターソール）が固定される
。今日では、内底が皮革で作られることは殆んどない。[Prior Art] The inner sole is an important part of shoes. The upper part and the outer sole of the shoe are fixed to the inner sole. Nowadays, inner soles are rarely made of leather.

らない。The inner sole is usually made of cellulose or nonwoven material reinforced with a binder, and the outer sole is attached to the inner sole by sewing, stacking, or gluing. In most cases, the outsole is made by injection molding or foam molding plastic. Particularly in the case of casual or sports shoes, an extremely lightweight inner sole is required, which must be able to withstand foam molding or injection molding processes.

極めて不快なものとなる。However, when using foam or injection molding methods, traditional inner soles exhibit inherent drawbacks. This means that foam-molded or injection-molded plastics penetrate particularly into the lightweight inner sole material. This results in the opposite side of the inner sole becoming swollen or uneven. This can be extremely uncomfortable for the wearer of the shoe.

It merely describes the improved insulation and foot support provided by the inner sole.
また、上記西ドイツ公開公報における製造方法は、中空
熱可塑性ミクロ球のコストが高いという欠点を有する。Furthermore, the manufacturing method disclosed in the above-mentioned West German Publication has the disadvantage that the cost of the hollow thermoplastic microspheres is high.

クロ球は破裂するからである。The production of microspheres of this type is only possible with modern mechanical equipment that allows extremely precise temperature control. This is because the production of hollow microspheres is impossible when the temperature is abnormally low, and the microspheres burst when the temperature is abnormally high.

DISCLOSURE OF THE INVENTION The above object is achieved by an inner sole made of a non-woven material compounded with microspheres and hardened with a binder, wherein the microspheres are not only compact or hard; The inner sole provides the nonwoven material, including the binder, with properties that prevent it from penetrating the foamed or injection molded plastic.

分である。The hollow microspheres are sized in this way so that a high density of the inner sole is achieved when the plastic is injection molded or foam molded to attach the outer sole to the midsole of the shoe. Depending on the material of the microspheres, it may be sufficient for the inner sole to have 2 to 20% by weight of the nonwoven material containing the binder.

A preferred base of nonwoven material is fiber fabric. - Into the membrane, this nonwoven material is attached to the base by needle punching. Preferably, the base for the nonwoven material is
It is a tape-shaped fabric made of polypropylene.
固め合せの織物の展伸性は小さいので、内底の形状は安

の目的にかなったものである。Preferably, the microspheres are made using inorganic materials, such as synthetic materials or natural materials. The diameter of the glass microspheres in a preferred example is 0.04 to 0.08 m+s. In the case of microspheres whose diameters are in the nanometer (nm) range, silicon dioxide (SiO) with a density of 1.0 to 1.2 gr/cm3 has proven particularly advantageous. Metal oxides or mixtures of metal oxides are suitable for the purposes of the invention, as are non-water soluble organic and inorganic salts.

Typically, this binder is deposited and cured at the intersections of the fibers, rather than within the hollow spaces surrounded by the fibers.

、内底の密度はさらに高まる。However, these microspheres fall within the hollow spaces of the nonwoven material, so that the binder is also bonded within these hollow spaces, as at the intersections of the fibers. A canvas of some kind is stretched between the glass microspheres and the fibers. These canvases are made of latex,
The inner sole is sealed so that its air permeability is less than 61 g/d/sec. The inner sole is thus made dense by foaming or injection molding. These hollow spaces formed by the canvas also act as insulation, albeit somewhat smaller. Also, a similar binder is used. In this case, a low density and therefore light and flexible inner sole is obtained. Particularly hard microspheres with a diameter in the range of 5 to 50 nI11 are used, so that the hollow spaces within the nonwoven material are Complete embedding, but the desired breathability is easily obtained.The binder used is combined with the microspheres to form an almost flaky composition, so that the density of the inner sole is further increased.

、加工中において温度の影響をうけることは少ない。The advantage of the microspheres according to the invention compared to those described in DE 23231971 lies in their cost and manufacturing method. In other words, the microspheres of the present invention can be manufactured at a cost close to 12.5 times that of conventional products, and are less affected by temperature during processing.

ができる。Since the soles of the feet that are in close contact with the inner soles sweat, it would be extremely advantageous from both hygiene and health points of view if the inner soles were impregnated with disinfectant. Such disinfectants can be incorporated into the inner sole through the use of binders and fibers.
