Problems solved by technology

Therefore, it is difficult to generate a feeling of volume on the hair as a whole, and the three-dimensional effect is poor, so there is a disadvantage that the hairstyles that can be prepared are limited.
In addition, when polyamide fibers are bundled, there is a property that the fibers attract each other and gradually become bundled (hereinafter referred to as "bundling"), so even if they are not installed all over the wig base, the fibers may Agglomeration occurs to form multiple strand-like or bundle-like clusters, or a state in which the traces of the teeth of a comb remain when combing, and there are sides that tend to form an unnatural appearance

Embodiment 1

[0130] Embodiments of the present invention will be described in more detail below by describing examples.

[0131] In any of the examples and comparative examples, the preparation conditions are set so that the diameter reaches approximately 80 μm, the first artificial hair 3A and the second artificial hair 3B are prepared, and the respective bending rigidity values ​​of the first and second artificial hair 3A and 3B are measured. . In each embodiment and comparative example, the first artificial hair 3A and the second artificial hair are mixed in different proportions to prepare artificial hair bundles, and a 20cm-long hair bundle is pre-wrapped on an aluminum tube with a diameter of 25mm, and heat-treated Curl was imparted, the hair bundle was folded in half so that it had a length of 10 cm, and each hair was bonded to a net base of 5 cm×5 cm to prepare a sample. The sample was used for property evaluation as hair.

[0132] In Example 1, as the first artificial hair 3A, f...

Embodiment 2

[0136] In Example 2, the nylon 6 (PA6) fiber prepared in Example 1 was used for the first artificial hair 3A.

[0137] As the second artificial hair, fibers having a perfect circular cross-sectional shape and a sheath-core structure were prepared. Specifically, as the raw material chip of the part constituting the core, MX nylon grade nylon MXD6 (PAMXD6) chip manufactured by Mitsubishi Gas Chemical Company, Inc. was used, and as the raw material chip of the part constituting the sheath, NOVAMID 1020 manufactured by Mitsubishi Engineering-Plastics Corporation was used. Grade nylon 6 (PA6) slices, the weight ratio of nylon MXD6 slices and nylon 6 slices is set to 72:25. use Figure 4 In the production system of (B), the roll speeds of the first stretching roll to the fourth stretching rolls 15, 17, 19, and 22 were adjusted, and as a result, the cross-sectional diameter of the fiber was 81.6 μm. Here, since the diameter of the core is 72.9 μm, the cross-sectional dimension of t...

Embodiment 3

[0140] In Example 3, the nylon 6 (PA6) fiber prepared in Example 1 was used for the first artificial hair 3A.

[0141] As the second artificial hair, fibers having a perfect circular cross-sectional shape and a sea-island structure were prepared. Specifically, as the raw material slices of the part constituting the matrix (i.e., the sea portion), MX nylon grade nylon MXD6 (PAMXD6) slices manufactured by Mitsubishi Gas Chemical Company, Inc. were used, and as the raw material slices constituting the island portion, Mitsubishi Engineering-Plastics For nylon 6 (PA6) chips of NOVAMID 1020 grade manufactured by Corporation, the weight ratio of nylon MXD6 chips to nylon 6 chips was set to 65:35. The speed of each stretching roll was adjusted in the same manner as in Example 1 and Example 2, and as a result, the cross-sectional diameter of the fiber was 83.2 μm. Here, the cross-sectional structure in the axial direction of the second artificial hair is a structure in which there is ...

Abstract

Hair (3) is attached to a hairpiece base (2), which has been molded in the shape of a head. The hair (3) includes a mixture of a first synthetic hair (3A) made from an aliphatic polyamide resin and a second synthetic hair (3B) made from an aliphatic polyamide resin and a semi-aromatic polyamide resin, mixed at any ratio in the range of 30:50-60:40. The first synthetic hair (3A) and second synthetic hair (3B) have a flexural rigidity within a specified range, converted to the same diameter. The first synthetic hair (3A) and second synthetic hair (3B) have a flexural rigidity, converted to a diameter of 80 [mu]m, measured under conditions of 20 DEG C temperature and 40% humidity, of 7.8 10-5 N cm2 / strand or less, and the difference in flexural rigidity between the first synthetic hair (3A) and second synthetic hair (3B) is 1.5-2.0 10-5 N cm2 / strand. Thus, while maintaining the softness and high-temperature setting properties of polyamide fibers, the feeling of volume can be increased and binding properties can be improved.

Description

technical field [0001] The present invention relates to a wig in which hair containing polyamide fiber is attached to a wig base. Background technique [0002] A wig is constructed by attaching hair to a wig base that is molded into the shape of the head. The wig base is generally composed of synthetic resin artificial skin, net bottom (net bottom) or a combination thereof. On the other hand, as the hair, human hair or natural hair collected from other animals or artificial hair prepared from synthetic fibers is used. As artificial hair, fibers made of synthetic resins such as nylon and other polyamide resins, polyester resins, polyvinyl chloride resins, and acrylic resins are used as raw materials, overcoming the shortcomings of human hair such as low strength, fading, and retention of hairstyles. Among these fibers made of synthetic resin, polyamide-based fibers are more suitable for wig hair because of their softness and water absorption, which are close to human hair, ...
