More preferably, the polymer used as the coating material is a water-soluble polymer material. When the bamboo salt component is coated with the water-soluble polymer material, the release of the bamboo salt component may be maximized due to the water absorption of the water-soluble polymer material other than the tooth brushing pressure when brushing the toothbrush according to the present invention.

Preferably, the polymer used in the preparation of the bamboo salt capsule according to the present invention includes polyacrylic polymers such as polyacrylic acid, poly (meth) acrylate, and polyvinylacetate; Cellulose polymers such as cellulose, hydroxypropyl methyl cellulose, hydroxymethyl cellulose, methyl cellulose, ethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxyethyl methyl cellulose and carboxymethyl cellulose; Polyalcohol polymers such as polyvinyl alcohol, polyethylene glycol, polypropylene glycol, and polypropylene glycol copolymers; Polyvinylacetate phthalate; Polyethylene oxide; Latex; Shellac; Rosin waxes; Polyamide; polyester; Polyolefin; silicon; And at least one polymer material selected from the group consisting of synthetic rubbers.

More preferably, as the water-soluble polymer material used in the preparation of the bamboo salt capsules according to the present invention, a polyacrylic polymer, a cellulose polymer, a polyalcohol polymer, polyethylene oxide, or the like may be used alone or in combination.

Bamboo salt in the bamboo salt capsule according to the present invention may be used sambo bamboo salt, hazelnut bamboo salt or phosphate bamboo salt, the content of bamboo salt in the bamboo salt capsule is preferably 1 to 90% by weight relative to the total weight of the capsule.

In addition, the particle diameter of the bamboo leaf capsule prepared as described above is preferably prepared in 1 to 200㎛ size. The size of the particles of the bamboo salt capsules is an important factor in producing bristles by spinning the bamboo salt capsules and other mixtures, and the bamboo salt capsule particles having a size of less than 1 μm or larger than 200 μm are not easy to spin to prepare the bristles.

Bamboo salt capsules according to the present invention can be prepared by a method for producing microcapsules well known in the art. For example, a capsule evaporation method, a solvent evaporation method, a spray drying method, a fluidized bed method, or the like may be used.

Referring to the encapsulation process using the fluidized bed method of the capsule manufacturing method, the bamboo salt is finely powdered using a ball mill, and dried. The dried fine powder is added to a fluidized bed device (CHUNGJIN TECH FBCG-1), and the binder is sprayed to encapsulate the binder solution so as to meet the bamboo salt content of 1 to 90% by weight through a spray nozzle at the side or bottom of the container while the device is operated and flowed. .

As the binder, a polymer obtained by dissolving the polymer used as the coating material in an appropriate amount of solvent (preferably ethanol, water or a mixed solvent thereof) at 1 to 50% by weight may be used. The temperature of the inlet hot air during encapsulation is 30 to 100 ° C., and the particle diameter of the resulting final capsule is 1 to 200 μm.

The bamboo salt capsules prepared as described above are mixed in a proportion with polypropylene, polyethylene, polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyurethane or nylon components which are used to prepare conventional bristles. With this mixture, bristles are prepared by conventionally known extrusion spinning methods.

At this time, the content of the bamboo salt capsule is preferably 0.5 to 10% by weight of the final bristle weight. The bamboo salt capsule content of less than 0.5% of the final bristle weight is insignificant, and it is difficult to show the effect of bamboo salt on brushing. There is a problem that can not be.
