Problems solved by technology

[0020] When the hair made of polyester fibers and the hair made of nylon fibers described in the above-mentioned Patent Document 2 are mixed and attached to the wig base, the nylon fibers can be prevented from bundling each other, but the behavior of the nylon fibers is the same as that of natural hair. Lodging, in contrast, polyester artificial hair stands up, it is difficult to blend perfectly with natural hair and nylon fibers, and it presents a separated appearance
This tendency becomes more pronounced as the humidity increases. In a state of high humidity, nylon fibers adhere to each other on the scalp similarly to natural hair due to the hygroscopic force, but polyester fibers have high bending rigidity and It has poor hygroscopicity, so it keeps standing up, so there is no natural feeling, and it is easy to see that it is wearing a wig

Embodiment 1

[0128] Next, embodiments of the present invention will be described in detail.

[0129] use Figure 8 The spinning machine 30 shown produces artificial hair made of polyethylene terephthalate. As a raw material for artificial hair, pellets of polyethylene terephthalate (manufactured by Toyobo Co., Ltd., density 1.40 g / cm 3 , melting point is 255°C) and a coloring resin based on polyethylene terephthalate resin and black, yellow, orange, and red pigments in weight percents of 6%, 6%, 5%, and 5% respectively pellets.

[0130] The spinning conditions were such that the melting temperature of the pellets was 270° C. as the discharge temperature from the discharge port, and the discharge port was equipped with a nozzle having 15 holes with a diameter of 0.7 mm. The temperature of the warm bath 33 was 40°C.

[0131] Regarding stretching conditions, the speeds of each of the first stretching rolls 34 to 4th stretching rolls 40 were adjusted so that the average cross-sectional dia...

Embodiment 2

[0139] Except for changing the stretching conditions, it carried out similarly to Example 1, and produced the artificial hair whose cross-sectional size had an average diameter of 50 micrometers.

Embodiment 3

[0141] Except for changing the stretching conditions, it carried out similarly to Example 1, and produced the artificial hair whose cross-sectional size had an average diameter of 55 micrometers.

Abstract

An artificial hair bundle (10) is made up by mixing a first artificial hair made of a polyester resin (1, 2) and a second artificial hair made of a polyamide resin, and the first artificial hair (1, 2) is made of polyethylene terephthalate and polybutylene terephthalate, having a cross-sectional size and bending rigidity similar to those of natural hair, wherein the bending rigidity is in the range of about 6.5 to 7.8 X 10 -3 gf cm 2 / strand at humidity 40 %, and the first artificial hair (1, 2) suppresses bundling of the second artificial hair (5), and the first and the second artificial hairs (1, 5) behave similarly to natural hair.

Description

technical field [0001] The present invention relates to artificial hair having a feel and physical properties close to hair, that is, natural hair, a wig equipped with the artificial hair, and a method for manufacturing the artificial hair. Background technique [0002] Generally, hair, that is, natural hair, has a diameter of about 80 to 100 μm. It is naturally curled or curly through perm treatment, but it has the characteristic of being unraveled and elongated when it is wetted by rain or shampoo. . In addition, it is known that the wetness of the hair, touch, etc., or the physical property values, such as bending rigidity, change with the increase or decrease of humidity. Therefore, as the hair used in wigs, it has always been preferred to use natural hair collected from humans or animals as a material to have characteristics as close as possible to natural hair of humans. However, in recent years, due to other reasons such as restrictions on the supply of natural hair...
