As for the insole, hygiene can be maintained by using a detachable insole.

However, no matter how the liner has excellent properties such as air permeability and sweat absorption, the hygiene is deteriorated because sweat and dirt adhere as the number of days of use increases. Can't be spared. Rather, those having better properties such as air permeability and sweat absorption are more likely to cause bacterial growth and accumulation of dirt due to their porous structure and hydrophilicity.

[0009] Such a problem of hygiene can be improved by using an antibacterial liner as a liner, but the effect is only to suppress the growth of bacteria and to prevent accumulation of dirt and darkening. It cannot be prevented.

Under such circumstances, the present invention provides a liner that is detachable, has abrasion resistance, air permeability, sweat absorption, and drying properties, and has a moderate elongation during use. It is an object of the present invention to provide a hygienic sock-like liner that does not wrinkle and that has good shape-preventing properties, cushioning properties, softness, washing properties, and comfortable feeling.

[0011]

The sock-shaped liner of the present invention is a three-dimensional liner to be used by being fitted in a shoe, and has a three-dimensional shape which entirely covers the instep, sole and heel of the foot, The main constituent member is a knitted fabric knitted by double Russell knitting, and is constituted by a three-layer knitted fabric including a surface layer, a back layer, and an intermediate layer connecting the front and back layers in the thickness direction. It is characterized by having.

A liner detachable shoe according to the present invention comprises the above-mentioned sock-shaped liner (1) and a shoe without a liner (2).

Hereinafter, the present invention will be described in detail.

The sock-shaped liner of the present invention has a main member comprising a knitted fabric knitted by double Russell knitting, that is, a three-layer structure comprising a surface layer, a back layer, and an intermediate layer connecting these front and back layers in the thickness direction. It is composed of a knitted fabric.

Double raschel knitting is a kind of three-dimensional knitting and is performed by a double raschel knitting machine represented by a mylar knitting machine. FIG. 3 is a schematic sectional view of a knitted fabric knitted by double Russell knitting. The yarn constituting the surface layer and the back layer is preferably a single or plural kinds of multifilament yarns such as polyurethane, nylon and polyester, and the yarn constituting the intermediate layer is preferably a rigid monofilament yarn such as nylon and polyester.

According to the double raschel knitting, the thickness of the knitted fabric can be from about 1 mm to a maximum of about 8 mm, and can be set arbitrarily in the present invention, but is usually about 1.5 to 3.5 mm.

The sock-shaped liner of the present invention is a three-dimensional liner that is used by being fitted into shoes, so that the entire liner has a three-dimensional shape that covers the instep, the sole and the heel.

Since it is generally difficult to make a three-dimensional shape with one piece, the above-described double raschel knitted fabric is cut to produce several pieces (cut pieces) as described below, and these pieces are cut out. Are appropriately combined and sewn to form a three-dimensional shape. Examples of pieces include a piece covering the inside half of the instep, a piece covering the outside half of the instep, a piece covering the tip of the instep, a piece covering the heel of the foot, and covering the side from the heel of the foot Pieces, pieces covering the soles, and the like can be given, and cutting can be performed so that two or more pieces are connected in series.

In this case, care should be taken that all or the main part of each piece is made of a double raschel knitted fabric. Some of the pieces (eg, the piece covering the heel of the foot) may be made of another member such as artificial leather.

When formed in a three-dimensional shape, the toe side is often non-branched (bag shape), but the toe side may be formed in a branched shape. Examples of the branched shape include a tabi shape in which the thumb and other fingers are separated, and a glove shape in which five fingers are separated.

The knitted fabric by the double raschel knitting may be subjected to antibacterial processing, deodorizing processing, fragrance, etc. as necessary at any stage of a raw fabric stage, a piece stage, and a three-dimensional sewing stage. It can be performed.

The sock-shaped liner (1) of the present invention having the above-mentioned structure is used in combination with a linerless shoe (2) that has been manufactured so that it fits snugly. However, the socks-like liner (1) can be used by fitting it into a slightly larger size ordinary shoe.

[0023]

The sock-shaped liner of the present invention is used for a shoe without a liner (in some cases, a slightly larger regular shoe).
Used by fitting into Since this sock-shaped liner is made of a knitted fabric by double raschel knitting, it has a moderate elongation to fit a foot, but does not wrinkle during use and does not lose its shape. This knitted fabric has abrasion resistance, breathability, sweat absorption, and dryness due to its special knitting method, and has good cushioning properties, softness, washability, comfort, and hygiene. It is.

When the sock-shaped liner becomes dirty due to use, it may be removed from the shoes and washed, and the shape does not collapse even by washing. Therefore, not only comfort is good, but also hygiene is always maintained.

(See FIG. 3). The thickness of the knitted fabric was 2 mm. A 70 denier polyurethane multifilament yarn was used for the surface layer and the back layer, and a 30 denier nylon multifilament yarn was used for the intermediate layer.

This knitted fabric was cut into the shape of a piece (1a) covering the inside half of the instep, a piece (1b) covering the outside half of the instep, and a piece (1c) covering the sole of the foot. Separately, artificial leather /
The laminated sheet composed of the polyurethane sponge layer / polyurethane thin film was cut to produce a piece (1d) for covering the heel of the foot, and the upper edge was bent outward and adhered to form an edge decoration (1e).

These pieces were sewn to form a three-dimensional sock-shaped liner (1) as shown in FIGS.
When this sock-shaped liner (1) was used by fitting it into a separately manufactured shoe without a liner (2), it had a moderate elongation, so it fits the foot, and it does not wrinkle or lose its shape during use. Was. Further, the abrasion resistance, the air permeability, the sweat absorption, the drying property, the cushioning property, and the softness were good, and the wearing comfort was extremely preferable. The sock-shaped liner (1) can be removed and washed, and no shape collapse was observed by the washing.

[0030]

The sock-shaped liner of the present invention does not wrinkle during use and does not lose its shape while having a moderate elongation that fits the foot. Also wear resistance, breathability,
It has a sweat-absorbing property and a drying property, and also has good cushioning properties, softness and comfortableness.
