Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to hair styling tools such as combs and brushes made of carbon fiber and synthetic resin, and the object thereof is that the hair styling tool of the present invention is made of synthetic resin. Regardless of the use, it does not generate static electricity, has excellent deformation resistance against heat, has excellent chemical resistance, and is reinforced with carbon fiber, making it an easy-to-use and hygienic hair styling tool. This is what we are trying to provide.

Conventional materials for hair styling tools include natural materials such as tortoiseshell, spittlewood, animal tusks, horns, and bones, as well as synthetic resins and metals, but each has its own drawbacks, such as falling.

For example, hair styling tools made from natural materials such as benzene, ivory, buffalo wood, and spittle wood are extremely expensive.

Metal products are heavy, have high friction, have poor passage through the hair, and lack elasticity.

Synthetic resin products have become popular recently, but they tend to generate static electricity, have poor permeability through the hair, and attract foreign matter.

Also, when cutting hair, combing the hair and cutting it with scissors on the surface of the comb, static electricity is generated.
Hair adheres to the scissors in clusters, causing problems such as hair being cut off in clusters.

Furthermore, since the bending modulus is low, combs must be made thicker, and brushes must have thicker bristles.

Furthermore, during heat sterilization or chemical sterilization, depending on the type of synthetic resin, deformation may occur at around 100°C, and the chemical may cause deformation or stickiness, among other drawbacks.

The present inventor has conducted various studies in an attempt to provide a hairdressing tool that can overcome the above-mentioned drawbacks, and as a result has arrived at the following invention.

That is, the present invention relates to a "hairdressing tool made of a synthetic resin reinforced with carbon fibers having an aspect ratio of 5 or more, short fibers or continuous fibers, or fabric."

The carbon fiber to be mixed with the synthetic resin in the hair styling tool of the present invention is particularly preferably a high-grade carbon fiber having a Young's modulus of 150 kg/ff1 or more.

Further, when the carbon fibers are short fibers, it is desirable that the aspect ratio (ratio of fiber length to diameter) is 5 or more.

The amount of carbon fiber added to the synthetic resin varies depending on the purpose, but is usually used in the range of 1.2 to 78% by weight.

The advantages of a hair styling tool created by mixing carbon fiber with synthetic resin are clear from the following example.

In other words, the electrical resistivity of synthetic resin is usually 1014/Ω or more, but carbon fiber has good electrical conductivity and has an electrical resistivity of 1
0-3/Ω crrL ~ 10-4/Ω is certain, so just mixing 1.5 to 2% by weight of carbon fiber with synthetic resin is considered to be the limit value for static electricity damage ■ Electrical ratio below 06/Ω Sakaki begins to show resistance.

However, in this case, the carbon fibers used in the mixture must be short fibers, continuous fibers, or fabrics with an aspect ratio of 5 or more.

If short carbon fibers with an aspect ratio of 5 or less are used, the effects of the present invention cannot be fully exhibited.

In other words, since the hair styling tool of the present invention does not generate static electricity, hair does not get tangled when styling hair with a comb or brush.
Hair styling is easy and does not damage your hair.

Furthermore, since no static electricity is generated on hair, brushes, combs, etc., it exhibits excellent effects such as preventing foreign matter from adhering to hair, brushes, combs, etc.

Next, to explain the shape retention property of the hair styling tool of the present invention against heat, for example, the thermal deformation limit of nylon 6 resin is 60
℃, but by mixing 15% carbon fiber with the resin, effects such as raising the temperature to 190°C can be obtained.

Furthermore, depending on the selection of resin, a product that can withstand even higher temperatures can be obtained.

Furthermore, carbon fiber has excellent chemical resistance and is resistant to any type of chemicals, so the hair styling tool of the present invention retains its shape well and does not have a sticky surface despite the use of synthetic resin.

In particular, when big-grade carbon fiber is used in the present invention, the carbon fiber has high strength and high elastic modulus, so the wall thickness of the comb can be made very thick, and when making a brush, the bristles can be made very fine. It has the effect of making hair styling easier and giving a beautiful finish.

Next, embodiments of the hair styling tool of the present invention will be described based on the drawings.

FIG. 1 shows a monofilament-like material 3 made by solidifying a continuous fiber body 1 with a synthetic resin 2.
The bristles 15 are cut to the length of the brush bristles 15 shown in FIG.

Further, a hair styling tool material 5 as shown in FIG. 2 is made of a synthetic resin 6 with a carbon fiber fabric 4 pasted on the front and back sides, and a hair styling tool material 8 as shown in FIG. , a hair styling tool material 11 in which carbon fibers 10 are mixed in a synthetic resin 12 as shown in FIG. 4 is used as the stand 14 in FIG. is fixed to the stand 14 in FIG. 6 by flocking.

Alternatively, a brush 13 as shown in FIG. 5 and a brush handle 14 as shown in FIG. It is also possible to obtain

The above is merely an example of the present invention, and the present invention is not particularly limited thereto.
