Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates, in the structure of human footwear, the inner surface of the material, contain a ultra fine conductive fibers in the material of the bottom surface, the electrostatic is attenuated by neutralization phenomenon at the tip of the conductive fibers, Human Body The present invention relates to footwear such as shoes, slippers, and the like, which reduce the number of shoes. Here, the neutralization phenomenon means that if there is a charged substance,
This is a physical phenomenon in which opposite ions are collected at the tip of the conductive fiber, and positive and negative ions are combined to neutralize and attenuate the charge.

2. Description of the Related Art Conventionally, as a countermeasure against static electricity in footwear, a method of using a conductive material for a sole and grounding the earth (Japanese Utility Model Application No.
71131) . That is, it is a conductive shoe. On the other hand, the sewing thread of the shoe (Sanderon : Commodity
Name ) A method using a conductive material has also been adopted. However, the effect is insufficient depending on the condition and the material of the floor surface, and there is a drawback that the conductive shoes are not effective particularly on a carpet, plastic or wood floor. In the above-mentioned conventional conductive shoes, the effect is insufficient, so that only a fixed position worker wears a hand wristband and grounds the worktable. This was very inconvenient.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the conductive shoes described in the above prior art.

[0004]

Means for Solving the Problems] antistatic footwear according to the present invention, for achieving the above object has the following configuration.
That is, a material having a weave degree of 0.5 denier to 1.5 denier and a length of 0.2 to 25 mm of the conductive fiber is 2 to 30% by weight.
The inner surface material coated on one side in the range described above is fixed to all or a part of the inner surface such as the bottom, side and top of the footwear body in contact with the human body in a state where the coated surface is opposite to the human body. A material having a weave of conductive fiber of 0.5 denier to 1.5 denier and a length of 0.2 to 25 mm and a weight ratio of 0.2 to 25 mm are added to a material such as rubber and fibrous material in a portion in contact with the ground at the bottom of the footwear body. %.

[0005]

In the present invention, the ultrafine short fiber conductive material has its tip exposed on the inner surface material and the surface of the bottom material , and functions as an antenna, collecting charged objects and ions opposite to generated static electricity from the air. Causes a neutralization phenomenon and attenuates static electricity.

The conductive fiber material may be a PAN-based carbon fiber, a pitch-based carbon fiber, or a metal-plated fiber, but it is preferable that the denier is as thin as possible and the fiber length is as long as possible. The mixing ratio to be contained is optimally 3 to 7%, but the effect is reduced when it is 2% or less. In addition, 30%
Above, the material cost is high, and it takes time to mix. When compounding with the rubber of the bottom material or coating the material of the inner surface,
The dispersion of the conductive fibers must be as uniform as possible.
For this purpose, it is better to stir using a high-viscosity stirrer over a long period of time, and it is better to stir slowly so that the fiber length does not break.

[0007]

Antistatic footwear according to the present invention is, carpet, plastic, be one that exerts sufficient anti-static function even on the floor of the timber, a complete response to completely achieve the intended purpose To play.

[0008]

EXAMPLES (First Example) PAN raw carbon fiber (poly, acrylic, nitrile) having a weave of 0.7 denier was cut into 5 mm, and 6% by weight was blended with rubber for shoe soles to obtain low viscosity. After slowly stirring with a stirrer, the mixture is kneaded with a kneader (a type of rubber kneading machine), put into a shoe mold, molded, and vulcanized at 150 ° C. for 10 minutes to produce a shoe sole. On the other hand, 5% of the same fiber is mixed with a water-soluble acrylic resin, slowly stirred with a low-viscosity stirrer, coated on one side of artificial leather with a comma and a doctor knife, dried with a dryer, and dried with a dryer. To manufacture. This is bonded to a core material, and the coating side is bonded to the core material. This is because when the coating side comes into contact with the human body, the coating falls off due to friction. This material was punched into a predetermined mold to create an inner surface portion, thereby creating a women's low heel shoe. Human body charging when flying in a jet airliner wearing these shoes and flying to New York, and human body charging while wearing ordinary shoes were as follows.

[0009]

[Table 1] The temperature and humidity inside the machine at this time were 25 ° C. and 30%.

(Second Embodiment) A nickel-plated polyester fiber having a weave of 1.0 denier is cut into 7 mm, 5% by weight is blended with a water-soluble acrylic resin, and slowly stirred with a low viscosity stirrer. A blended fiber of 65% polyester and 35% cotton is coated with a pipe coater knife and dried in a drier to produce an inner material for shoes. This is bonded to a core material, and the coating side is bonded to the core material. This is because when the coating side comes into contact with the human body, the coating falls off due to friction. This material is stamped into a predetermined mold to produce an internal part. On the other hand, a sewing thread (Sanderon : trade name ) plated with copper sulfide was used as a sewing thread for sewing shoes. Wearing these shoes and performing normal work in a large-scale hotel (building), human body electrification was as follows, and human body electrification costs could be prevented.
