Problems solved by technology

[0005] On the other hand, artificial hair made of PET (polyethylene terephthalate, polyethylene terephthalate) resin has the following disadvantages: Compared with human hair, it is straight and smooth, so it has a strong luster and unnatural style. In addition, the tip of the hair tends to curl over time (hereinafter referred to as "frizziness"), and once curled, it takes a lot of labor and time to correct it
[0008] However, on the other hand, PBT resin has disadvantages such as poor curling properties due to high elastic recovery rate, and poor curling properties due to low glass transition point
[0013] However, according to the research of the inventors of this case, PTT resin generally shows properties close to PBT resin, and the curly hair and curly hair setting properties are not good.

Embodiment 1-1～ Embodiment 1-4

[0130] As the PET resin of the sheath component, MA-2103 (intrinsic viscosity: 0.68) manufactured by UNITIKA CO., LTD. was used. In addition, 5 parts by weight of a masterbatch containing 5% of silica manufactured by Tosoh Silica Co., Ltd. as a matting agent was prepared with respect to 95 parts by weight of the PET resin. Novaduran 5010L (intrinsic viscosity 1.0) (PBT resin) manufactured by Mitsubishi Engineering-Plastics Co., Ltd. was used as the core component. The extruder temperature of the sheath part was set at 285°C, the extruder temperature of the core part was set at 270°C, the PET resin and the PBT resin were melted, and the core / sheath weight ratio was respectively 5 / 95 (Example 1 -1), 10 / 90 (embodiment 1-2), 20 / 80 (embodiment 1-3), 30 / 70 (embodiment 1-4) mode regulates the discharge amount of described composition, from hole number 60 Each core-sheath composite fiber is spun into a cooling tank with a spinning head, and then stretched to 4 times in hot water at 9...

Embodiment 1-5～ Embodiment 1-8

[0134] Asahi Kasei Chemical Co., Ltd. manufactured PTT resin crystallized product (intrinsic viscosity 1.0) (PTT resin) as the core component, in the same manner as the above-mentioned Example 1-1 to Example 1-4, to obtain Examples 1-5 where the core / sheath weight ratio is 5 / 95, Examples 1-6 where the core / sheath weight ratio is 10 / 90, and examples where the core / sheath weight ratio is 20 / 80 1-7, and Examples 1-8 in which the core / sheath weight ratio was 30 / 70. Then, with respect to these Examples 1-5 to 1-8, the same steps of weight reduction treatment, dyeing treatment, reduction cleaning treatment, oil agent application, drying, cutting, and combing as the above-mentioned treatments were implemented.

Embodiment 2-1 and Embodiment 2-2

[0144] In addition to carrying out the reduction treatment so that the reduction rate using an alkaline aqueous solution becomes 25%, each treatment was carried out according to Examples 1-2 and Examples 1-6, and the implementation of obtaining black artificial hair with a fineness of 67 dtex was obtained. Example 2-1 and Example 2-2.

[0145] The obtained artificial hair was evaluated for its physical properties, core / sheath area ratio, frizziness, and curling property. These results are shown in Table 3.

[0146] [table 3]

[0147]

[0148] It can be seen from Table 3 that the artificial hair of Example 2-1 and Example 2-2 have the same curly hair setting properties as human hair, but the curly properties are slightly worse.

Abstract

The purpose of the present invention is to provide: artificial hair having the same levels of curling properties and shrinking properties as those of human hair, excellent curling / setting properties, and similar styling properties and texture to those of human hair; and a wig comprising the artificial hair. The artificial hair is of a core-sheath type, wherein a polybutylene terephthalate resin or a polytrimethylene terephthalate resin is used as a core component and a polyethylene terephthalate resin is used as a sheath component. The artificial hair is composed of polyester monofilaments (F), in each of which a core part (Fa) and a sheath part (Fb) are arranged approximately concentrically.

Description

technical field [0001] The present invention relates to an artificial hair including a polyester monofilament. More specifically, the present invention relates to an artificial hair including a polyester monofilament having a core-sheath structure, and a wig using the same. Background technique [0002] Conventionally, human hair has been favored as hair for wigs because it is close to natural hair, especially one's own hair. However, in recent years, with regard to human hair, not only has the supply become increasingly difficult, but also trimming is labor-intensive and time-consuming, and if it is wet, the styling is easily disturbed, and the hair is easy to tangle with each other. For these reasons, synthetic fibers have begun to be used. Raw material artificial hair. [0003] As raw materials for artificial hair, there are acrylic (modified acrylic or vinyl chloride, etc.), polyamide (nylon 6 or nylon 66, etc.), polyester (polyethylene terephthalate or polybutylene ter...
