があつた。 Conventionally, antistatic shoes have been devised in which the soles are integrally molded by injection molding using a conductive resin composition, and the midsoles have holes (Utility Application No. 45-99477). ). In the injection molding of anti-static shoes, a perforated insole with a sewn cover is hung on the last, and the sewn product is suspended on the last using an outer mold consisting of a bottom mold and a side mold. This is done by providing a space for the sole of the shoe, wrapping it, and injection molding a conductive resin into the space. However, during this injection molding, there was a risk that the injected molten resin would enter between the last and the midsole through the hole in the midsole, causing the resin to stick to the surface of the midsole when the shoe was finished.
本発明はこのような欠点の生じない射出成形帯
電防止靴の製造法を提供するものである。 The present invention provides a method for manufacturing injection molded antistatic shoes that does not suffer from these drawbacks.

止靴の製造法に係わる。 That is, the present invention provides a method of integrally forming a shoe sole by injection molding using a conductive resin composition into an integral body of a shoe cover and a midsole having one or more holes. The present invention relates to a method for manufacturing antistatic shoes characterized by using a layered film of a conductive resin composition.

る。 In the present invention, the insole having one or more holes includes not only an insole with a hole, but also an insole with a semicircular hole on the edge (periphery), and an insole with a hole in the insole. It also includes an insole with a net-like material made of conductive material bound to the sole side of the shoe to enhance the antistatic effect. In the latter case, a film made of a conductive resin composition is bound to the sole side of the net.

The conductive resin composition is prevented from protruding, and it is no longer possible to manufacture defective products in which the resin composition is stuck to the surface of the midsole during the finishing of shoes.
