Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing doll's hair, and more particularly to a method for manufacturing a doll's hair that allows a doll user to freely change their hairstyle.

Conventional technology and its drawbacks For conventional doll's hair, straight filaments molded in a straight line from a plastic molding machine are cut to the required length, and the straight hairs are planted on the head, and the straight filaments are cut by a curl machine. In some cases, the curl filament is wound so as to have a curl of about 10 to 20 mm, heat-treated to obtain a curl filament, and the curl filament is flocked to the head.

Hair using straight filament maintains straightness and has the appearance of straight hair, but even if a combing force is applied to this hair, it will easily return to straight hair due to the elasticity and tensile properties of the straight filament. , It is not possible to curl hair with a comb and create various desired hairstyles.

Moreover, since the hair using the conventional curl filament retains the curl of the diameter given by the curl machine over the entire length protruding from the scalp, the filaments are not aligned in the natural state at all. It is difficult to comb, and even when the comb is applied, bending forces in different directions are applied to each filament, so even after combing, many filaments likewise curl in random directions. It is difficult to create and hold the desired hairstyle as it restores.

In view of the above-mentioned problems, the present invention makes it possible for a doll user to change their hairstyle and enjoy by combing their hair and holding the curl in the direction of the comb. The present invention aims to provide a doll having a hair that is made possible.

Means for Solving the Problems In order to solve the above-mentioned problems, according to the present invention, firstly, it is molded with vinylidene chloride having a thickness of 500 to 1200 denier or a synthetic resin material having elasticity and tensile properties equivalent to those after molding. A curl having a diameter in the range of 5 to 20 mm is attached to the filament by a curl machine, and the heat-treated curl filament is applied to the head of the doll.

Secondly, the curl filament is annealed in such a manner that the curl filament extends straight at the top of the doll and the curl filament is curled in a desired direction at portions other than the top of the doll.

Action A filament formed of a synthetic resin material having the above-mentioned thickness, elasticity and tensile properties is used to have a diameter of 5 to 2 by a curl machine.
A curl filament with a curl in the range of 0 mm is heat-treated, and the curl filament is annealed in a straight stretched state at the top of the doll, so that the top of the head always has a substantially linear filament. Since it keeps the same condition, it is easy to comb the hair of this doll. In addition, the portion other than the crown portion retains the curl applied before annealing. However, if you apply a combing force to the curl part and apply a bending force with the comb in the opposite direction to the curl direction, the curl of each filament will change direction to the combing direction and will be aligned, and the filaments will remain in each curl filament. The filament curl is held in the diverted direction by the comb to prevent recovery due to stress and tensile properties. In this way, the hairstyle can be changed depending on the direction of combing.

Embodiments of the Invention Next, embodiments of the invention will be described with reference to the drawings.

First Step As shown in FIG. 1 (a), the filament 1 is molded from vinylidene chloride or a synthetic resin material having elasticity and tensile properties equivalent to those after molding. The thickness of the filament is preferably in the range of 500 to 1200 denier for the reason described below. Next, as shown in FIG. 7B, the filament is curled with a curl machine in the range of 5 to 20 mm in diameter and heat-treated to maintain the coil state. The curl filament 2 thus obtained is flocked to the head 3 of the doll as shown in FIG.

Second step Subsequently, in the head portion of the doll in which the curl filaments 2 are flocked, the hair is straightly extended with a comb or the like and fixed by binding with the band 4, and in the portions other than the head portion, the curl filaments 2 are combed. To form a curl with a slightly gentle wave in the desired direction. In this case, depending on the tensile characteristics of the material of the curl filament, that is, the stress-strain characteristic, a tensile force is applied to the extent that the small curl diameter of the filament before the tensile force is applied causes permanent distortion to the extent that a doll comb is easily formed. .

Therefore, the tensile force applied in this case depends on the thickness of the filament 1 used.

Then, when the filament is curled according to the hairstyle, as shown in FIG. 2, at the position to be curled, the finger 5 is on the side where the filament is to be curled,
For example, in the case of curling to the outside, the filament is applied to the outside, and the filament is strongly combed so as to curl along the circumference of the finger with the comb 6, and this is repeated several times.

In this manner, the top of the head is straightened, and the portion other than the head is curled or curled and waved, and placed in an oven for annealing to remove the residual stress of the curled filament. As a result, each filament retains a straight state at the crown portion and a combed curl or curl and wave at the other portions.

FIGS. 3 (a), (c), and (d) show examples of head hair having three types of hairstyles produced as described above.

Then, when changing the inner winding style of (a), as shown in Fig. 2, put the fingertip on the outer side near the tip of the hair on the outer side of the bundle of filaments curled inward, and use the comb to move the outer side. If you comb it hard a few times towards you, the filament will remain curled and twist and turn in the combed direction.
The elastic and tensile properties of the filament material act to restore the original state with a small force from the curled state, but since the filaments are evenly oriented in the same direction, Restoration is prevented, and the curled state is maintained for a relatively long time, so that the outer curled style is finally retained as shown in the third state (b), which is curled by the comb.

In addition, the soft long hairstyle as shown in the same figure (c), which was manufactured by alternately combing outward and inward at multiple points in the length direction of the hair, put the fingers on each curl part in the same way. By combing, the hair style can be changed to have different curl and wave directions, and the hair was manufactured by curling the hair from the front side to the back side one by one in a fixed direction. The layered hairstyle shown in FIG. 9D can be changed to another different hairstyle.

In order to curl the hair in any direction by the force applied by the doll comb as described above and hold and change the hair style, when the filaments are combed due to the pulling property, the directions are aligned and combed. It is necessary for the material to satisfy the condition that strain is generated by the bending force applied from the filaments and that the restoration of the filaments due to the elasticity is mutually blocked by the filaments aligned with each other.

It is preferable that the filament made of such a material is made of vinylidene chloride or a synthetic resin material having elasticity and tensile properties equivalent to those of this after molding, and the thickness of the filament is optimally 1000 denier, If it is thicker than this, it becomes difficult to align the filaments when curling with a doll comb. Also, the thinner it is than 1000 denier, the shorter the duration after changing the style. From this point of view, the applicable range is 500 to 1200.
It is denier.

EFFECTS OF THE INVENTION As described above, according to the present invention, by using a doll comb to apply a fingertip or the like to a filament and comb the filament in a desired direction, a desired curled state is maintained depending on the direction in which the comb is applied. You can change the style and enjoy.
