Description

Footwear with static elimination function

Technical field

The present invention relates to footwear having a static elimination function.

Background art

There are various adverse effects when static electricity is charged on the human body. For example, in a dry winter environment, static electricity may be generated, and when the finger approaches a metal doorknob that is easily charged, the static electricity may be discharged and an unpleasant electric shock may be received.

There are various causes of static electricity generation, but the foot soles and the ground are strongly rubbed during walking, which is a major cause of static electricity generation. If the footwear is charged, it will be charged by electrostatic induction.

[0004] Therefore, conventionally, footwear and the like have been proposed for the purpose of neutralizing the static electricity generated by the strong rubbing of the sole and the ground, and, for example, conductivity having at least a raised surface on the ground surface side has been proposed. There is known an antistatic material for footwear characterized by having fibers (see Patent Document 1).

Problem that invention tries to solve

However, the above-mentioned conventional static electricity removing material for footwear is a conductive woven fabric or the like in which conductive fibers are woven. In order to fix the conductive woven fabric or the like to the footwear bottom, it is necessary to fix at least the entire periphery of the conductive woven fabric or the like to the footwear bottom using a double-sided tape, an adhesive or sewing as a fixing means. For this reason, there is a problem that it takes time to attach the conductive cloth or the like to the bottom of the footwear. In particular, when there is unevenness for anti-slip on the bottom of the footwear, it is necessary to cut and attach a conductive cloth etc. according to the unevenness, and it takes time to attach.

In addition, when the conductive woven fabric etc. rubs against the ground, it wears off immediately and when the conductive fiber wears off, the static electricity removing function of the static electricity removing material is lost. For this reason, the above-mentioned conventional static electricity removing material for footwear can not maintain the static electricity removing function over a long period of time. [0007] Therefore, a first object of the present invention is to provide a footwear with a static elimination function which can easily provide a static elimination function.
