PROBLEM TO BE SOLVED: To provide a conventional dental floss in the form of a single thread. As a result, the usable dental floss that was cut during cleaning and was caught in the treatment traces of the teeth and could not be cleaned well was sometimes wasted. Since it is a thin thread, it takes time to clean only one place, and there is a problem that dental floss is difficult to use. SOLUTION: Dental floss whose main feature is a material, which is made of a specific material such as polyurethane fiber and has an annular, thin and high strip-like appearance, which makes it easy to hold and makes a polished part. By significantly increasing the number and forming the surface smoothly, we solved the conventional problems by proposing elastic, soft and hard-to-cut dental floss. [Selection diagram] Fig. 1【課題】従来のデンタルフロスは、１本の糸状であった。そのため清浄中に切れ、歯の治療跡に引っ掛かり上手く清浄出来ない、使用可能なデンタルフロスが無駄になる事があった。細い糸の為１カ所しか清浄出来ず時間を要し、デンタルフロスが使いにくいという課題があった。【解決手段】材質を主な特長としたデンタルフロスで、ポリウレタン繊維などの特定の材質で作られた、環状で、薄く高さのある帯状の外観にする事で、持ちやすく、かつ磨き部を大幅に増やし、表面を滑らかに形成する事で、弾性と柔らかく切れにくいデンタルフロスを提案する事によって、従来の課題を解決した。【選択図】図１
