Artificial hair for hair-implantation and preparation process and preparation apparatus thereof

An apparatus for the preparation of artificial hairs for hair-implantation, comprising:

• a vacuum vessel, a vacuum pump communicating with the vacuum vessel through an on-off valve, a crucible disposed in the vacuum vessel equipped with a heater for fusing silver, and a rotary container provided in the vacuum vessel adapted to receive monofilaments of a synthetic resin therein whereby amorphous silver is caused to adhere in spots to the monofilaments by subjecting said monofilaments to vacuum deposition of said silver at a vacuum degree of 10.sup.-3 -10.sup.-6 Torr at monofilament substrate temperatures of 36.degree. C. or lower upon rotation of said container;
• wherein the rotary container is formed of a hollow cylinder having closed side ends and wherein said cylinder is provided with a plural number of openings which are made by cutting off a circumferential wall of said hollow cylinder in a vicinity close to said side ends or one side end of said hollow cylinder so as to expose free ends of monofilaments of artificial hairs held in said rotary container.
