Embodiment 1

[0111] Next, examples of the present invention will be described in detail.

[0112] The artificial hair 10 of Example 1 was manufactured using the spinning machine 20 shown in FIG. 3 . Nylon 6T (manufactured by TOYOBO Corporation) was used as the polyamide resin of the core portion 1B, and nylon 6 (manufactured by TOYOBO Corporation) was used as the polyamide resin of the sheath portion 1A. The hot water bath 24 uses hot water of 80°C. The sheath / core capacity ratio was set to 1 / 7, and the outlet temperature was set to 310° C. to produce artificial hair 10 . The sheath / core weight ratio of the artificial hair 10 of this Example 1 was 12 / 88.

[0113] As a coloring agent, the polyamide resin and pigment used in the sheath 1A or core 1B are mixed in a predetermined ratio, heated and melted, kneaded and then cooled to form a sheet-like resin flake. The resin flake used as this colorant is called a masterbatch. As master batches used in the examples, resin flakes containing 3%...

Embodiment 2

[0121] The artificial hair 10 having the sheath / core structure was produced under the same conditions as in Example 1 except that the gear pumps 21B, 22B were adjusted so that the sheath / core capacity ratio was 1 / 5. The sheath / core weight ratio of the artificial hair 10 of this Example 2 was 16.1 / 83.9.

Embodiment 3

[0123] The artificial hair 10 having the sheath / core structure was produced under the same conditions as in Example 1 except that the gear pumps 21B, 22B were adjusted so that the sheath / core capacity ratio was 1 / 3. The artificial hair 10 of Example 3 had a sheath / core weight ratio of 24.2 / 75.8 and a diameter of 80 μm.

[0124] FIG. 7 is a graph showing the elongation ratio dependence of the bending rigidity value of the artificial hair 10 of Example 3. FIG. In the figure, the horizontal axis represents the elongation ratio, and the vertical axis represents the bending rigidity value (10 -5 gfcm 2 / root). The measurement conditions were a temperature of 22° C. and a humidity of 40%. It can be seen from Figure 7 that the bending rigidity values ​​of 3 times and 5.5 times of elongation are respectively 430×10 -5 gfcm 2 / root, 720×10 -5 gfcm 2 / root, the bending rigidity increases linearly as the elongation ratio increases.

Abstract

An artificial hair which is closely similar to natural hair in appearance, touch and feeling such as texture and has favorable physical data close to natural hair and a wig using this artificial hair. This artificial hair (1) has a core / sheath structure consisting of a core part (1B) and a sheath part (1A) covering the core part (1B). By using a polyamide resin, in particular, a semiaromatic polyamide resin for the core part (1B) and a polyamide resin, in particular, a straight-chain saturated aliphatic polyamide having a lower bending rigidity than the core part (1B) as the sheath part (1A), for example, the bending rigidity close to natural hair can be obtained. Moreover, changes and behaviors of the artificial hair depending on humidity change can be controlled in such a manner closely similar to natural hair. By using this artificial hair, therefore, it is possible to provide a wig having a natural feeling and an excellent appearance.

Description

technical field [0001] The present invention relates to artificial hair having a physical and feeling close to natural hair and a wig using the artificial hair. Background technique [0002] Wigs have been manufactured using natural hair as a raw material since ancient times and have been widely used by people. In recent years, due to restrictions on the supply of natural hair raw materials and other problems, synthetic fibers are often used as raw materials for wigs. In this case, the synthetic fibers to be used are selected with the first goal of being close to natural hair in terms of feeling and physical properties. [0003] As the artificial hair raw materials used, there are many synthetic fibers such as acrylic, polyester, polyamide, etc., but generally speaking, due to the low melting point and poor heat resistance of acrylic fibers, they have poor shape retention after perming, For example, if it is exposed to hot water, it will curl and other processing will becom...
