DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulky fiber for doll hair composed of multifilaments and a method for producing the same. More specifically, there is a doll hair having a specific flicker feeling given by crimping, a doll hair having a crimp obtained by using the fiber, and a wave obtained by subjecting it to a curling process. About doll hair.

[0002]

2. Description of the Related Art In human hair, for example, crimped hair such as that found in many blacks and Hispanic races, and curly-like hair obtained by perming, the hair 1 Each book has a unique flicker due to the fine crimp. Conventionally, in order to realize these hairstyles with doll hair, for example, a method of using a spun yarn as it is, or sandwiching it between two planted straight metal fibers with a corrugated hot metal plate to obtain a corrugated crimp has been used. Was.

[0003] However, when spun yarn is used, there is a problem that gloss is lost, combing is poor, and it is difficult to prepare a hairstyle. Further, a material processed with a metal plate is not partially crimped. And there is a problem that heat-sealing is easy and combing is poor. In recent years, hairstyles have been diversified.For example, curly-like hairstyles, which are made by curling like curly hair using a curler and then perming, are prevalent mainly in the black market. I have. For dolls, there is a long-awaited need for a fiber material that can easily form such a hairstyle.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a crimped hairstyle or a curly-like hairstyle, each of which has a fine crimp and natural luster and combability. Is to provide a doll hair fiber.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies focusing on the crimp shape of the fibers. As a result, when crimps are applied under certain conditions, fine crimps are applied to each of the crimps. It has been found that the use of dolls can realize a crimped hairstyle and a curly-like hairstyle with the same flicker and glossiness as human hair in a doll. Further, since the doll hair fibers are excellent in combing, these hairstyles can be easily neatly arranged. Also,
The present inventors have found that when the fibers are curled by a curling machine for a multifilament and the hairstyle is adjusted, crimped wavy hair can be easily obtained in a doll, and the present invention has been completed. That is, the present invention is a bulky fiber composed of multifilaments, and has an apparent bulk specific gravity after crimping of 0.05 to 0.25 g / cm.
³ is a doll hair fiber.

In the production method of the present invention, the multifilament is crimped by a wooly processing method and / or a gear crimping method so that the apparent bulk specific gravity becomes 0.05 to less.
This is a production method of 0.25 g / cm ³ . Further, using the bulky fiber for doll hair according to claim 1, a curl diameter of 3 to 2 is used.
Curling processing can be performed to make the hair of the doll 5 mm.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The term "multifilament" as used in the present invention refers to an aggregate of two or more continuous monofilaments, and these materials are those usually used for doll's hair. There is no particular limitation, and examples thereof include synthetic fibers of polyvinyl chloride, polyvinylidene chloride, polypropylene, polyamide, polyester, polyethylene, polyacrylonitrile, and the like. Among these, polyvinylidene chloride-based fibers or polyacrylonitrile-based fibers are preferred in that they have excellent gloss as doll's hair.

[0008] The total fineness of the multifilament may be the fineness usually used for hair for dolls, and is not particularly limited. If it is too large, it becomes bristle and makes it difficult to plant hair, or wooly processing or gear crimping. Since there is a problem that it is difficult to obtain a uniform crimp when processing,
It is preferably 000 denier (hereinafter abbreviated as d) or less, and more preferably 1500 d or less. Also,
If the fineness is too small, thread breakage tends to occur easily when flocking or curling with a doll-specific sewing machine, so it is preferably at least 200d or more, preferably 400d or more. The fineness of the monofilament constituting the multifilament having the total fineness described above is about 5d to 75d, preferably 10 to 50d.

The apparent bulk specific gravity used in the present invention is used as an index of bulkiness, and refers to the weight per unit volume of a multifilament including a space provided by crimping, and is measured by the following method. Things. In other words, a multifilament is precisely 10
Bundled into a cylindrical shape, around which 100% cotton 3
No. 0 sewing thread (for example, Kanebo-made katan thread Y-TK
−03) is fixed, and the other end wound around the circumference of the cylinder one round is attached with a weight of 5 g, and its circumferential length R
Measure (cm). Next, the weight W (g) is measured and calculated by the following equation. Apparent bulk specific gravity (E) = 0.126 × W / (R × R) The larger the value of apparent bulk specific gravity is, the higher the bulkiness is.
Gloss is lost and combing tends to be poor.

The wooly processing method referred to in the present invention means, for example, a hollow spindle method in which a twisting machine is fixed using a heater, after twisting, using an Italian-type twisting machine, a ring twisting machine, a double twister or the like, which is usually used for filaments, or ,
Crimp is applied by the ironing method and heat setting is performed. Various conditions are taken depending on the twisting machine used and the method of providing the crimp. For example, in the hollow spindle system, it may vary depending on the fiber material, denier, number of twists, heater temperature, heat setting conditions after twisting, and the like. The filament obtained by this wooly processing method is called a wooly yarn (also called a false twist yarn).

The gear crimping method referred to in the present invention is defined as 2
A method of imparting crimp by passing a filament between two meshing high-temperature gears, which varies depending on the fiber material used, denier, fraction of gears, temperature, pressure conditions between gears, heat setting conditions after processing, etc. Can. The apparent bulk specific gravity has an optimum value that differs depending on the hair design to be obtained. In the wooly processing method, the apparent bulk specific gravity can vary depending on the fiber material, denier, number of twisted yarns, heat setting conditions after twisting, and the like. In the gear crimping method, the fiber material, denier, fraction of gear, temperature,
It depends on many parameters such as pressure conditions and heat setting conditions after processing. In the present invention, these processing conditions are not particularly limited, as long as the desired apparent bulk specific gravity can be obtained.

In the present invention, the apparent bulk specific gravity is 0.05
To 0.25, preferably 0.10 to 0.20. When the apparent bulk specific gravity is less than 0.05, the crimp is large and the bulk is increased, but the luster is lost, and at the same time, the combability is unfavorably deteriorated. Is not preferable because it is no longer observed.

In the present invention, bulky doll hair fibers can be obtained by crimping the multifilament by a wooly processing method and / or a gear crimping method. If used as it is, a hair style with a subtle change in gloss due to the addition of a fine straight crimp can be expressed. Also,
By further curling this fiber,
It is also possible to cope with hair styles that have subtle changes in glossiness in a wave-like manner.

When the crimp is applied to the multifilament by the wooly processing method, an irregular crimp can be applied, so that it is possible to express a natural (irregular crimp) crimped hair style such as black and redhead. Orientation, crimping by gear crimping method can give regular crimp, so it is more suitable for expression of ethnic style and curly like style, but there is no big difference in the effect of both these processing methods The usage is not particularly limited.

The multifilament is subjected to a curling process by a curling machine (a process for obtaining a curled yarn by heat-setting while continuously winding the yarn around a rod) to prepare a hairstyle. By using a ribbon-curl style style with a fine crimp, and even using a comb,
You can create crimped wavy or silky reddish style hairstyles. Here, the curl diameter is not particularly limited as long as it is in the range of 3 to 25 mm usually used for dolls, and hairstyles having waves of various sizes can be obtained according to the curl diameter. The size of these curl diameters is not particularly limited depending on the size and hairstyle of the doll head used, but if it is too small, combing becomes poor and it is difficult to arrange the hairstyle, and if it is too large, curling will occur. There is a problem that processing by the machine becomes difficult. Also in these wave-like styles, the effect obtained by the fibers obtained by the wooly processing method and the gear crimping method does not greatly differ, and the usage is not particularly limited.

The doll hair referred to in the present invention is not particularly limited. For example, after hair is continuously planted on a generally used soft vinyl chloride head using a continuous length fiber with a doll sewing machine. And those obtained by arranging the planted fibers with a comb. The method for obtaining the multifilament curling yarn processed as described above is not particularly limited. For example, if a commonly used multifilament curling machine is used, 3 to 2 may be used.
A curl diameter of 5 mm can be obtained. Hair for dolls with curled yarn processed with this curling machine,
Although not particularly limited, the hair can be implanted on a commonly used soft vinyl chloride head with a doll sewing machine.
