Description

The present invention relates to a brush using silk, which can be suitably used as a brush for people and pets.

Silk has excellent physical properties, such as being soft to the touch, shiny, moisturizing, and having high strength. In addition, it has excellent biocompatibility so that it can be used as a suture thread for surgery.

However, when silk is used as bristles for brushes, the fibers are too thin and pliable, making them weak and making the brushing effect of straightening the hair in the same direction less effective.

In order to solve these problems, Patent Document 1 proposes that silk be compounded with animal fibers such as pig fibers to strengthen the waist and used as hair for brushes.
Furthermore, Patent Document 2 proposes that silk is twisted into a composite fiber with water-soluble sericin or fibroin to strengthen the waist, and that this is used as hair for a brush.

However, with the above-mentioned conventional brushes using silk, although the strength of the bristles is increased, the tip of the silk comes into direct contact with the scalp, making the silk easy to bend and get tangled, making brushing less effective. There was a problem that it became difficult to demonstrate. The present invention was developed in view of the above-mentioned conventional situation, and the problem to be solved is to provide a brush that uses silk for its bristles, with less silk entanglement and high brushing effectiveness. There is.

The brush of the present invention is a brush consisting of a brush body and fibers flocked to stand up from the brush body, and the fibers are made of silk and reinforcing fibers that are stronger than the silk, The length of the reinforcing fiber is longer than the length of the silk.

In the brush of the present invention, reinforcing fibers are implanted in the brush body along with silk as bristles. For this reason, the strong reinforcing fibers provide a strong brushing effect by arranging the hair in a certain direction. Furthermore, since the length of the reinforcing fibers is longer than the length of the silk, the tip of the reinforcing fibers directly touches the scalp when brushing, and the weaker tip of the silk does not directly touch the scalp. This prevents the silk from contacting the scalp and bending, making it less likely to get tangled. In addition, silk has a two-layer structure in which sericin covers the surface of fibroin, and sericin has excellent moisturizing properties, so when hair is brushed, it comes into contact with sericin on the silk surface, adding moisture to the hair. It has a moisturizing effect. Furthermore, since sericin has the property of adsorbing amino acids, which are components of dirt on the skin surface, it also exhibits the effect of removing dirt from hair. In addition, static electricity is less likely to occur during friction, and irritation to the scalp is alleviated.

Preferably, the reinforcing fibers are made of synthetic fibers and/or animal fibers.
This is because synthetic fibers and animal hair have the property of being strong, so they can easily serve as reinforcing fibers. As the synthetic fiber, nylon, polypropylene, polyester, etc. can be used. Further, as the animal fiber, pig hair, horse hair, goat hair, boar hair, etc. can be used.

Preferably, the reinforcing fibers are flocked to surround the silk.
This is because the effect of reinforcing the silk with the reinforcing fibers increases.

(Length of reinforcing fiber h ₁ )/(Length of silk h ₂ ) is preferably in the range of 1.1 to 2.0. According to the inventor's test results, if (length of reinforcing fiber h ₁ )/(length of silk h ₂ ) is in the range of 1.1 to 2.0, appropriate moisture will be applied to the hair when brushing. The effect of applying and moisturizing the hair and the effect of removing dirt from the hair are likely to be exhibited. It also makes it less likely that your hair will stand up on end due to static electricity and that you will be less likely to receive an electric shock from static electricity discharge. Furthermore, the reinforcing fibers tend to have the effect of reinforcing the weak waist of silk.

It is a photograph of the brush of Example 2 viewed from the front. It is a photograph of the brush of Example 2 seen from a plane.

Hereinafter, embodiments embodying the present invention will be described in detail.
(Example 1)
As shown in FIG. 1, the brush of Example 1 has two types of fibers implanted in a plastic brush body 1. The flocks are arranged in five rows parallel to each other at equal intervals, three of which are reinforcing fibers 3a, 3b, and 3c made of nylon, and a row of silk 4a is inserted between the rows of reinforcing fibers 3a and 3b. , a row of silk 4b is inserted between the rows of reinforcing fibers 3b, 3c. The reinforcing fibers 3a, 3b, 3c shown in FIG. 2 have a protruding length _h1 of 20 mm from the brush body 1, and the silks 4a, 4b have a protruding length _h2 of 12.5 mm. Therefore, the value of h ₁ /h ₂ is 1.6.

- Manufacturing method The brush of Example 1 was manufactured by the following method.
A plastic brush body 1 is prepared. A recess (not shown) is provided in the part of the brush body 1 where the hair is to be implanted, and the brush of Example 1 was manufactured by folding a bundle of bristles in half and inserting and fixing the bundle into the recess using a metal caulking tool. .

- Effects during use In the brush of Example 1, nylon bristles, which are stronger than silk, are implanted in the brush body 1 as reinforcing fibers 3a, 3b, and 3c. Therefore, the reinforcing fibers 3a, 3b, and 3c exert a strong brushing effect of arranging the hair in a certain direction. Here, the length of the reinforcing fibers 3a, 3b, 3c is 1.6 times longer than the length of the silk 4a, 4b, so when brushing, the tips of the reinforcing fibers 3a, 3b, 3c directly touch the scalp; The tips of the silks 4a and 4b are difficult to reach the scalp due to their weak texture. This prevents the silks 4a and 4b from contacting the scalp and bending during brushing, making them less likely to get tangled. Furthermore, as shown in FIG. 3, the silks 4a and 4b have a two-layer structure in which sericin 6 covers the surface of fibroin 5, and sericin 6 has excellent moisture retention properties. Therefore, when the hair is brushed, the hair comes into contact with the sericin 6 on the surface of the silk, and an appropriate amount of moisture is imparted to the hair, resulting in a moisturizing effect. Furthermore, since sericin 6 has the property of adsorbing amino acids, which are components of dirt on the skin surface, it also exhibits the effect of adsorbing and removing dirt from hair. In addition, static electricity is less likely to be generated during friction, and static electricity can prevent hair from standing on end and electric shocks due to static electricity discharge can be prevented.

(Example 2)
As shown in FIG. 4, the brush of Example 2 has a wooden brush body 11 in which pig hair, which is stronger than silk, is implanted as reinforcing fibers. The flocks are arranged in five rows parallel to each other at equal intervals, three of which are reinforcing fibers 13a, 13b, and 13c made of nylon, and a row of silk 14a is inserted between the rows of reinforcing fibers 13a and 13b. , a row of silk 14b is inserted between the rows of reinforcing fibers 13b, 13c. However, the length of the rows of silks 14a, 14b is shorter than the length of the rows of reinforcing fibers 13b, 13c, and the reinforcing fibers are successively arranged at the leading and trailing ends of the rows of silks 14a, 14b. As a result, the silks 14a and 14b are surrounded by reinforcing fibers made of pig hair.

The protruding length _h1 of the reinforcing fibers 13a, 13b, 13c is 20 mm, and the protruding length _h2 of the silks 14a, 14b is 12 mm. Therefore, the value of h ₁ /h ₂ is approximately 1.7.

- Manufacturing method The manufacturing method is the same as that of the brush of Example 1, and detailed explanation will be omitted.

- Effects during use In the brush of Example 2, strong pig hair is implanted in the brush body 11 as reinforcing fibers so as to surround the silks 14a and 14b. Therefore, the brushing effect of aligning the hair in a certain direction is strongly exhibited. Here, the length of the reinforcing fiber is 1.67 times longer than the length of the silks 14a and 14b, so when brushing, the tip of the reinforcing fiber made of pig hair directly touches the scalp, and the weak silk 14a, The tip of 14b does not touch the scalp directly. This prevents the silks 14a and 14b from bending when they come into contact with the scalp, making them less likely to get tangled. In addition, the silks 14a and 14b have a two-layer structure in which sericin 6 covers the surface of fibroin 5, as shown in FIG. When it comes into contact with sericin 6 on the surface of silk, it imparts moisture to the hair and has the effect of moisturizing it. Furthermore, since sericin 6 has the property of adsorbing amino acids, which are components of dirt on the skin surface, it also exhibits the effect of removing dirt from hair. In addition, static electricity is less likely to be generated during friction, and static electricity can prevent hair from standing on end and electric shocks due to static electricity discharge can be prevented.

This invention is in no way limited to the embodiments and examples described above. This invention includes various modifications that can be easily conceived by those skilled in the art without departing from the scope of the claims for utility model registration.
