Description

Oral tools including cut loop hairs {TOOLS FOR ORAL CONTAINING CUT AND LOOP HAIRS}

The present invention relates to a tool comprising a hair of cut loop tissue.

Oral tools generally used, specifically toothbrushes, etc. are used to remove foreign substances in the oral cavity by cutting the cross section to a certain height or by varying the length of the fabric at the end of the bristles. However, in this case, there is a problem that it is not good for oral hygiene and oral refreshing because the effect of simply pushing the foreign material to another place is large rather than completely catching the foreign material and discharging it into the oral cavity.

An object of the present invention is to provide an oral cleaning tool having excellent oral cleaning power.

In order to achieve the above object, the present invention provides an oral cleaning tool including a hair having a cut loop structure.

In the case of washing the oral cavity with the oral cleaning tool of the present invention including a hair having a cut loop structure, as foreign matter is easily removed by being caught between the cut loop and the loop, it is possible to fundamentally remove foreign matter in the oral cavity, The efficiency of removing foreign substances can be increased. That is, in the case of using the oral cleaning tool of the present invention, the hair tissue having the cut loop structure has excellent adsorption power to completely wipe the teeth by pulling out plaques or food debris from the tooth surface and fine tooth gaps, It has the advantage of superior brushing effect than conventional oral cleaning tools. As described above, the oral cleaning tool of the present invention has excellent cleaning power and can be used without a separate cleaning solvent such as toothpaste, and it is useful because the oral cleaning can be easily performed even in the absence of water.

2 is a photograph of the actual shape of the cut loop simulation used in the present invention.

In one aspect, the present invention relates to an oral cleaning tool, comprising a hair having a cut loop tissue.

In the present specification, the "cut loop" may refer to a weaving tissue such as a fabric or a fluff formed by cutting a ring created from a weaving tissue. In the present specification, the “cut loop structure” may be manufactured by knitting yarns to have a loop, that is, a ring structure, and then cutting the obtained loops in several places.

The reason why the cleaning effect of the cut loop structure is excellent is that the loop structure pulls and removes contaminants from the surface, and the cut structure removes contaminants between the gaps.

In addition, since the loop and the cut structure are mixed, there is an effect that contaminants are trapped and removed between the loop structure and the cut structure, rather than a case made of only a loop structure or a case made of only the cut structure.

However, if the yarn is used as a microfiber in the manufacture of a fabric having a cut loop structure, there is an advantage in that the wiping property increases at the beginning of brushing, but the repulsion elasticity is low because the microfiber is so thin that the elasticity and resilience are poor. When the microfiber absorbs water or is pressed under pressure, the threads exist in a clumped or tangled state, and there is a problem in that the tooth brushing effect is deteriorated due to poor pushability.

Therefore, the outer part of the yarn used in the manufacture of a fabric with a cut loop structure is microfiber, and the inner part is made of powdered yarn with excellent resilience and elasticity, so that even if the microfiber absorbs water or is pressed under pressure, it recovers immediately and pushability. Not only can this deterioration be prevented, but also an oral cleaning tool excellent in absorbency, quick-drying property, and touch can be obtained by microfiber.

In the oral cleaning tool according to an aspect of the present invention, the oral cleaning tool may include a toothbrush or a tooth tissue.

The toothbrush or dental tissue may be prepared by a general method known in the art, except for using a hair having a cut chuf tissue. Specifically, it may be manufactured by combining the tissue of the cut loop to a part or the whole of the toothbrush head hair transplanting part in which nylon hair or fine hair is hair transplanted.

Meanwhile, the toothbrush includes, without limitation, a disposable toothbrush, a folding toothbrush for travel, an electric toothbrush, a finger insert toothbrush, and an assembly toothbrush.

Hereinafter, the present invention will be described in more detail through the following examples. However, the following examples are provided for illustrative purposes only to aid understanding of the present invention, and the scope and scope of the present invention are not limited thereto.

[Example 1] Preparation of hair having cut loop structure

320 denier/8 filament polyester split yarn is used as the core yarn, 150 denier/72 filament nylon/polyester split microfiber (each filament is 8 split, polyester and polyamide are 80% and 20, respectively) %) was used as the covering yarn, and the twisted yarn was twisted so that the number of twists was 600TPM from the twister to the first S strand, and the second was twisted so that the number of twists was 540TPM with Z strands. For the core yarn, the covering yarn was twisted into S and Z yarns, respectively, and then heated to 120 degrees for 40 minutes to set it to prepare a yarn. The thus-prepared yarn was knitted to have a loop structure in a weaving machine, and then weaved, and the loop obtained by weaving was cut to produce a wool having a cut loop structure.

[Example 2] Preparation of toothbrush including hair having cut loop structure

A toothbrush was manufactured by combining the plastic toothbrush holder handle, the neck connected to the handle, and the hair tissue having the cut loop structure of Example 1 to the head portion located at the tip of the neck portion.

[Example 3] Preparation of a dental tissue containing a hair having a cut loop structure

The parent tissue having the cut loop structure prepared in Example 1 was cut into a square to prepare a tooth tissue.

[Comparative Example]

A toothbrush was manufactured by combining a plastic toothbrush handle, a neck connected to the handle, and a hair tissue having a nylon filament structure in a head portion located at the tip of the neck portion.

[Experimental Example 1] Plaque reduction effect of teeth

Plaque index was measured to confirm the effect of reducing plaque. First, after selecting 40 subjects, taking antibiotics and receiving oral treatments that may affect the experiment were prohibited during the experiment. Each subject was divided into two groups of 20 subjects, and toothbrushes of Example 1 and Comparative Example were used for each group, and then the plaque index was measured. For the examination, 10 drops of disclosing solution were mixed with 20 ml of water, soaked in the mouth for 1 minute, spit out, and rinsed lightly with water. The staining condition was performed using a probe and an alveolar, and Quigley &Hein's Turesky modification criterion was applied as a score criterion for the dental plaque index.

* Based on the tooth surface bacterial membrane rating

0=If the tooth surface bacterial film is not attached at all

1=If there is a plaque on the gingival edge

2=If there is an annular tooth surface bacterial film of less than 1mm in the cervical area

3=If there is an annular tooth surface bacterial film of 1 mm or more on the tooth surface less than 1/3 of the cervical side

4=If there is a tooth surface bacterial film on the tooth surface less than 2/3 of the cervical side

5=If there is a tooth surface bacterial film on the tooth surface of more than 2/3 of the cervical side

** Tooth surface bacterial membrane index = total score / 20

As a result, the results shown in Table 1 below were obtained.
