Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to doll's hair having excellent water repellency. More specifically, even after children bring the doll to the bath and put the doll's hair in warm water and play it through a comb or shampoo, the hair can be easily drained and dried, resulting in the original hair style. The present invention relates to a doll's hair having a novel function of being easily restored.

[0002]

2. Description of the Related Art As one of the ways to play with children's dolls, there is a way to play with them, such as taking them in a bath with their hair, combing their hair or shampooing. Often done. Especially recently, temperature-sensitive color-developing materials that reversibly color-decolor according to temperature have come to be used on the body and hair of dolls.
The number of cases where such playing methods are performed is increasing.

Conventionally, synthetic fibers of nylon, polypropylene, polyvinyl chloride, polyvinylidene chloride, and modacrylic are used as doll's hair, but these doll's hair easily gets wet. , Once in water, it contains a lot of water between the hair, and even if the hair is drained, the fibers of the hair gather in a dull shape, and the hair style easily collapses. In addition, if the comb is passed in this state, the hair is stretched in one direction and stretched, and because the weight containing a large amount of water between the hair causes the curls to grow easily, once the hair is treated in this way, There was a drawback that the original hairstyle could not be reproduced even after being dried.
Therefore, children can easily drain the doll's hair after putting it in hot water, passing it through combs, playing shampoo, and having the function of quickly drying the hair and restoring the original hairstyle. There is a strong demand for hair.

[0004]

Means for Solving the Problems As a result of intensive investigations by the present inventors to improve the above-mentioned drawbacks of doll's hair, a fiber obtained by subjecting a conventional synthetic fiber to a water-repellent treatment satisfies this function. The present invention has been completed and the present invention has been completed.

That is, the doll's hair of the present invention is a synthetic fiber that has been subjected to a water-repellent treatment, and its water-repellent performance is that when a droplet of a 20 wt% isopropyl alcohol aqueous solution is adhered to the fiber bundle. Droplets do not penetrate the fiber bundle,
It is characterized in that the shape of the droplet is retained on the fiber for 1 minute or more.

[0006]

[Examples] As synthetic fiber materials used for the doll's hair of the present invention, nylon, polypropylene, polyvinyl chloride, polyvinylidene chloride, acrylic, polyester, modacrylic etc. Although any synthetic fiber may be used, synthetic fibers such as modacrylic, polyvinylidene chloride, polyvinyl chloride, and polypropylene having good curl retention are preferable.
Examples of the polyvinylidene chloride fiber include fibers made of a homopolymer of vinylidene chloride and a copolymer with vinyl chloride containing 80% by weight or more of vinylidene chloride. Examples of the polyvinyl chloride fiber include a homopolymer of vinyl chloride and a fiber containing a copolymer of 80% by weight or more of vinyl chloride and another monomer copolymerizable therewith. Examples of modacrylic fibers include fibers composed of a copolymer of 30 to 80% by weight of acrylonitrile and 70 to 20% by weight of vinyl chloride and / or vinylidene chloride. Usually, the fineness of these synthetic fiber filaments is 10 to 150 d in single yarn fineness and 200 to 20 in total fineness.
The thickness is 00d.

As the water-repellent treatment agent for subjecting the synthetic fiber to the water-repellent treatment, usual fluorine-based agents, silicone-based agents, zirconium soaps and the like can be used, but especially the water-repellent performance evaluated by the following method is 1 minute. More advanced fluorine system,
Silicone water repellents are preferred. Examples of the fluorine-based water repellent include ordinary fluoroalkyl group-containing water repellents and the like. Although not particularly limited, for example, CF ₃ (CF ₂ ) ₇ (CH ₂ ) ₂ OCOCH = CH
₂ , CF ₃ (CF ₂ ) ₄ CH ₂ OCOC (CH ₃ ) = CH ₂ , (CF ₃ )
₂ CF (CF ₂ ) ₁₀ (CH ₂ ) ₃ OCOCH = CH ₂ , (CF ₃ ) ₂ CF
(CF ₂ ) ₆ CH ₂ CH (OCOCH ₃ ) OCO (CH ₃ ) = CH ₂ such as a polymer of acrylate or methacrylate containing a fluoroalkyl group having 3 to 20 carbon atoms, preferably 4 to 15 carbon atoms. is there.

As an example of the silicone water repellent,
Examples thereof include methyl hydrogen polysiloxane, amino-modified polysiloxane, and OH-terminated dimethyl polysiloxane.

As a method of water repellent treatment, the water repellent treatment agent may be attached at the stage of producing the synthetic fiber, or the water repellent treatment agent may be attached by post-treatment. That is, as a method for attaching the water repellent treatment agent to the synthetic fibers, the synthetic fibers are usually immersed in the water repellent aqueous solution, but there are other means such as spraying the water repellent aqueous solution.

The amount of the water-repellent agent attached varies depending on the type of synthetic fiber or water-repellent agent and cannot be generally stated.
It is preferably at least wt%, more preferably at least 0.1 wt%. Water repellent performance improves as the amount of water repellent attached increases,
If it becomes too large, the feel of the fiber is impaired, so 5% by weight or less relative to the fiber is preferable.

The water-repellent performance of the synthetic fiber treated with the water-repellent treatment is as follows: the fiber bundle (thickness of about 300,000 d) is aligned straight and 20% by weight of isopropyl alcohol at 20 ° C. When one drop (0.03 ml) of an aqueous solution was gently placed, the drop did not penetrate into the fiber bundle and the shape of the drop was evaluated by the time it was retained on the fiber, which was 1 minute or more, It is necessary that it is preferably 3 minutes or longer, particularly preferably 5 minutes or longer. If it is less than 1 minute, the hair will be drained poorly after playing in warm water and it will take a long time to dry, so the fibers of the hair will become dull and the curls will not be able to restore to the original hairstyle.

[0012] Ordinarily, after being subjected to a water repellent treatment, it is continuously curled.

The doll's hair of the present invention will be described in more detail with reference to the following examples, but the present invention is not limited to these examples.

Example 1 0.4% by weight of a commercially available water-repellent agent containing a fluoroalkyl group-containing water-repellent agent as a main component was attached to modacrylic fiber (1100d-36f) for water-repellent treatment. This modacrylic fiber was continuously curled and then flocked to a vinyl chloride doll head. The water repellency of the modacrylic fiber of the present invention by the above method is 5 minutes or more.

After the hair style was adjusted with a brush, the doll head was placed in warm water at 40 ° C. and the hair was combed 10 times to wash the hair. After washing the hair, the head was shaken 5 times to remove water, and then the hair was further wiped with a towel to remove water, and the amount of water remaining on the hair was very small and was 11% based on the weight of the hair.

As described above, in the hair of this example, the fibers did not gather in a slump shape and the original curl was retained, and the original hair style could be easily adjusted.

Example 2 A mixture of 0.5% by weight of a commercially available water repellent containing methylhydrogenpolysiloxane and 0.1% by weight of catalytic Zn soap.
0.6% by weight of polyvinylidene chloride fiber (1000d-20f)
And then heat treated for water repellent treatment. The polyvinylidene chloride fiber was continuously curled, and then the hair was planted on a vinyl chloride doll head. The water repellent performance of this polyvinylidene chloride fiber by the above method is 5 minutes or more.

After styling the hair with a brush, the hair was washed and drained in the same manner as in Example 1. The moisture remaining on the hair was 9% of the weight of the hair,
In the hair of this example, the fibers were not aggregated in a dull shape and the original curl was retained in a substantially dry state, and the original hair style could be easily adjusted.

Comparative Example 1 Normal nylon fibers (1200d-24f) which had not been substantially water-repellent treated were continuously curled and then flocked to a vinyl chloride doll head. The water repellent performance of this nylon fiber by the above method is 1 second or less.

Then, after the hair style was adjusted with a brush, the hair was washed and drained in the same manner as in Example 1. The moisture remaining on the hair was 31% of the weight of the hair after draining.
And it was extremely large compared with the doll's hair of the present invention.

FIG. 2 is a photograph of the fiber shape of the doll's hair before washing the hair and FIG. 5 after washing and draining the hair.
As described above, in the hair of this comparative example, the fibers gathered in a slump shape and the curl was extended by the weight of the attached water, and the hair in such a state could not be adjusted to the hair style before washing.

Comparative Example 2 The same ordinary polyvinylidene chloride fiber as that used in Example 2 (1000d-2, which was not substantially treated to be water repellent).
After being continuously curled to 0f), hair was planted on a vinyl chloride doll head. The water repellent performance of this polyvinylidene chloride fiber by the above method is 1 second or less.

After styling the hair with a brush and then washing and draining the hair in the same manner as in Example 1, the moisture remaining on the hair was 25% of the weight of the hair after draining, and the hair for the doll of the present invention was It was extremely high in comparison.

FIG. 3 is a photograph of the fiber shape of the doll's hair before washing the hair and FIG. 6 after washing and draining the hair.
