Abstract
Artificial hair for hair-implantation, which is composed of a monofilament of a synthetic resin, wherein amorphous silver is adhered in spots to the surface of the monofilament by vacuum depositing said silver of the monofilament.
Claims4
In an artificial hair for hair-implantation, which is composed of a monofilament of a synthetic resin, the improvement wherein amorphous silver is adhered in spots covering about 20-80% of a distal end to surface of the monofilament by vacuum depositing said amorphous silver at between 10.sup.-3 to 10.sup.-6 Torr and at a monofilament temperature of 36.degree. C. or lower.
A process for the preparation of an artificial hair for hair-implanation comprising, causing amorphous silver to adhere in spots by vacuum depositing said silver at between 10.sup.-3 -10.sup.-6 Torr to surfaces of said artificial hair composed of a monofilament of a synthetic resin.
A process for the preparation of an artificial hair for hair-implantation comprising, causing amorphous silver to adhere in spots to surfaces of an end part of a monofilament composed of a thermoplastic synthetic resin by vacuum depositing said silver at between 10.sup.-3 -10.sup.-6 Torr, winding the deposited end part and fusion-bonding an intersection of the wound end part and a hair shaft part by high frequency spot welding to form a hair root part in an .alpha.-shape.
