Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a functional glove which has excellent waterproofness and heat retention and is designed so that it can be easily put on and taken off even though it fits in a hand.

[0002]

2. Description of the Related Art A foam sheet made of chloroprene rubber having closed cells has waterproofness, heat retention, rubber elasticity and stretchability, and is lightweight, so that it is suitable for use in winter gloves.

[0003] Cold protection gloves include gloves which are used for working or exercising in cold water or putting hands in cold water for working. In this case, it is necessary to have a size that fits in the hand so that water does not enter the inside as much as possible.

[0004]

However, in gloves that are made of a stretchable foam sheet and have a size that fits in the hand, if the rubber surface of the foam sheet is on the inner space side, it will be necessary to pass it up to the fingertips. It will require a lot of work. In such a case, the inner space side surface is laminated with a stretchable cloth such as nylon jersey so that it can be smoothly attached and detached (attached to or detached from the hand). The stretchable fabric laminate is also preferable from the viewpoint of improving the tear strength.

However, when the surface on the inner space side is a laminated surface made of a stretchable cloth in order to facilitate the attachment / detachment as described above, the water content, water retention, non-adhesiveness of the cloth,
It is unavoidable that the water resistance becomes low due to the capillary phenomenon and the cold weather resistance deteriorates. Therefore, such gloves are not suitable for applications such as working or exercising in cold water, or putting hands in cold water.

Under such a background, the present invention makes use of the advantages of the heat-retaining property and the adhesiveness to the hand of the stretchable foam sheet typified by the chloroprene rubber foam sheet, while keeping the inner space side surface. It is an object of the present invention to provide functional gloves that have improved slipperiness and are designed so that they can be easily put on and taken off even though they fit the hand.

[0007]

The functional glove of the present invention comprises:
A hand-fitting glove configured mainly with a stretchable foam sheet (1) having waterproofness, heat retention and rubber elasticity, which is a stretchable foam sheet (1) on the inner space side when used as a glove. It has a structure in which the stretchable polymer film (2) containing the slippery substance (x) is formed as a continuous or discontinuous film on the surface.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.

The stretchable foam sheet (1) may be made of various materials as long as it is a stretchable foam sheet having waterproofness, heat retention and rubber elasticity. Of these, a foam sheet made of chloroprene rubber having closed cells is particularly preferable, and a stretchable foam sheet having various elasticity such as polyurethane elastomer and chlorosulfonated polyethylene can also be used.

The stretchable foam sheet (1) is preferably made by laminating a stretchable cloth (3) on the outside of a glove. Lamination of the stretchable fabric (3) is advantageous in terms of improving tear strength, friction strength, joint strength, and the like.

As the stretchable fabric (3), various woven fabrics, knitted fabrics and non-woven fabrics prepared by adopting a knitting or weaving method in which the yarn itself has stretchability or stretchability are used. Nylon jersey is a representative example of what is preferred.

Instead of laminating the stretchable fabric (3) on the outside of the stretchable foam sheet (1), the stretchable foam sheet (1) in the shape of a glove is dipped in a rubber latex liquid. The tear strength can also be improved.

In the present invention, the stretchable polymer film (2) containing the slippery substance (x) is formed on the surface of the stretchable foam sheet (1) on the inner space side of a glove. To do so. In this case, the stretchable polymer film (2) is usually formed as a continuous film, but it can also be formed as a discontinuous film as long as it exhibits slipperiness. The stretchable polymer film (2) has a thickness of several μm to several hundred μm, usually 5 to 200 μm, and particularly 10 to 100 μm.

Polyurethane is particularly suitable as the film-forming polymer constituting the stretchable polymer film (2), but other polymers can be used as long as they have elastomeric properties.

As the slippery substance (x), various fluorine-based resins, particularly fine powder of polytetrafluoroethylene, are preferable, and solid or liquid silicon-based resin is also preferable. It is preferable to use a fluorine-based resin together with a silicon-based resin as the slippery substance (x) because the lubricity is further improved. When using a fluorine resin and a silicon resin together,
For example, add 1 part by weight of fluororesin to silicon resin.
Often 0.1 to 20 parts by weight are used. Other examples of the slippery substance (x) include molybdenum disulfide, polyethylene wax, low molecular weight polypropylene, higher alcohols, higher fatty acids and amides or esters thereof,
These may be used in combination with the above-mentioned silicon resin or fluorine resin, if necessary.

A slippery substance occupying the stretchable polymer film (2)
The ratio of (x) cannot be unconditionally determined because the optimum value varies depending on the type of the slippery substance (x), but it is an effective amount that provides the necessary lubricity and maintains the necessary film strength, Usually 0.2
About 50 to 50% by weight (preferably 0.5 to 40% by weight, particularly 1 to 30% by weight) is suitable. If the slippery substance (x) is too small, the detachability when putting the hand in and out of the glove is insufficient, and if too much, the film forming property is impaired.

The stretchable polymer film (2) contains a slippery substance.
The heat-retaining substance (y) can be blended together with (x). In this case, if the amount of the heat-retaining substance (y) is increased, the slippery property and the film strength may be deteriorated. The slippery substance (x) is used alone or as a heat retaining substance in the water-soluble polymer film (2a).
It is desirable that the heat-retaining substance (y) is added alone or together with the slippery substance (x) to the elastic polymer film (2b) on the back side. The amount of the heat retaining substance (y) to be blended is an effective amount (for example, 1 to 70% by weight, preferably 2 to 60% by weight) capable of exerting the desired heat retaining property.

Examples of the heat-retaining substance (y) include heat-reflecting substances (aluminum powder, etc.), far-infrared emitting substances (far-infrared emitting ceramics, etc.) and heat-storing substances (carbon black, etc.).

The stretchable polymer film (2) (or (2a), (2b)) is formed on the stretchable foam sheet (1) by a coating method using a coating agent that forms the latter film (liquid coating or Melt coating), and a printing method can also be adopted. In this case, if the adhesion is insufficient, first provide an anchor coating layer (ac) with an appropriate anchor coating agent on the surface of the heat insulating sheet (1), and then stretch the polymer film (2) (or (2a ), (2b)) can also be formed. Also, instead of the coating method or printing method, the stretchable polymer film (2) is previously prepared.
Alternatively, (or (2a), (2b)) may be prepared and laminated on the surface of the heat insulating sheet (1) with an appropriate adhesive or by heat.

The material on which the stretchable polymer film (2) (or (2a), (2b)) is formed in this way is used to produce gloves through steps such as cutting and sewing. The fingers of the glove are
The thumb, forefinger, middle finger, ring finger, and little finger are often independent, but the thumb is independent, and at least a part of the remaining four fingers is united to form a mittens or three-pronged glove. You can also do it.

On the outside of the palm part and the outside of the instep part when used as a glove, it is possible to attach irregularities for preventing slippage and reinforcing pieces for reinforcement.

The functional glove of the present invention having the above structure is
It is particularly useful as a glove used for working or exercising in cold water, or putting hands in cold water.

<Operation> In the functional glove of the present invention,
The stretchable foam sheet (1) typified by the chloroprene rubber foam sheet provides waterproofness, heat retention, rubber elasticity and stretchability, light weight, and a good fit, and the slippery substance (x). The blended stretchable polymer film (2) ensures the slipperiness of the surface on the internal space side. Therefore, even though it fits in the hand, it is easy to put on and take off. When the stretchable polymer film (2) is composed of multiple layers and the stretchable polymer film (2b) on the back side is blended with the heat-retaining substance (y), the smoothness of attachment / detachment can be improved. While securing, it is possible to further improve the cold protection.
