Abstract

Abstract A wig-like cool cap wherein an artificial hair is implanted to an artificial scalp portion. The artificial hair is composed of carbon fiber or fine thread form comprising twisted plural carbon fibers, while the artificial scalp portion comprises a central network portion (1) and an outer surrounding membranous portion (2). The central network portion (1) is composed of carbon fiber or fine thread form comprising twisted plural carbon fibers and is constructed in a network. The outer surrounding membranous portion (2) is arranged at an outer circumference of the central network portion and has a plurality of micropores. Because carbon fiber has very large coefficient of thermal conductivity and is superior in heat-releasing characteristic, it can prevent stuffiness and sweat peculiar to conventional wigs. Further, because carbon fiber is superior in resistance against chemicals, hair care products, coloring reagent and the like can be freely used. A cap of the present invention is manufactured in a manner that an artificial hair is penetrated through a sieve plate (4) and perforated frame (5) to be brought into contact with an artificial scalp portion (6), and thereafter the artificial hair is fixed.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 109 words
A wig-like cool cap wherein artificial hair is implanted into an artificial scalp portion wherein the artificial hair is selected from the group consisting of carbon fiber and a fine thread form comprising twisted plural carbon fibers, and that the artificial scalp portion comprises a central network portion and an outer surrounding membranous portion, the central network portion being composed of a material selected from the group consisting of carbon fiber and fine thread form comprising twisted plural carbon fibers and being constructed in a network, and the outer surrounding membranous portion being arranged at an outer circumference of the central network portion and having a plurality of micropores.
Claim 2
Dependent Claim 109 words
A wig-like cool cap wherein artificial hair is implanted into an artificial scalp portion wherein the artificial hair is selected from the group consisting of carbon fiber and a fine thread form comprising twisted plural carbon fibers, and that the artificial scalp portion comprises a central network portion and an outer surrounding membranous portion, the central network portion being composed of a material selected from the group consisting of carbon fiber and fine thread form comprising twisted plural carbon fibers and being constructed in a network, and the outer surrounding membranous portion being arranged at an outer circumference of the central network portion and having a plurality of micropores.
Claim 3
Dependent Claim 17 words
A wig-like cool cap according to claim 1 wherein hemp fiber is mixed into the carbon fiber.
Claim 4
Dependent Claim 19 words
A wig-like cool cap according to claim 1 wherein metal-galvanizing is applied to a surface of the carbon fiber.
Claim 5
Dependent Claim 16 words
A wig-like cool cap according to claim 3 wherein the metal-galvanizing is carried out with nickel.
Claim 6
Dependent Claim 16 words
A wig-like cool cap according to claim 3 wherein the metal-galvanizing is carried out with zinc.
Claim 7
Dependent Claim 16 words

Claim 8
Independent Claim 114 words
A method for manufacturing a wig-like cool cap comprising: a) forming a central network of fibres selected from the group consisting of carbon fibre, twisted plural carbon fibres and carbon fibres coated with a metal; b) attaching said central network to a porous outer circumferential portion formed of a different fibrous material; c) penetrating artificial hair selected from the group consisting of carbon fibre, twisted, small diameter carbon fibres and mixed fibres of carbon fibre and hemp through a sieve plate and then through a cranium-shaped perforated frame on the reverse side of which has been positioned said central network of fibres; and d) affixing said artificial hair to said central network of fibres.
