| Zusammenfassung: | The present invention relates to high-reflection toothbrush bristles including a reflection bead inside thereof. The concentration of the beads increases from the inside to the outside with respect to a cross-section vertical to a longitudinal direction. The present invention satisfies chemical formula 1. According to the present invention, an advanced filament having excellent scattering properties can be provided by including high-reflection beads inside thereof. Also, the diameters of the beads can be adjusted according to spinning requirements, and the cut of filaments can be prevented by insertion of the beads. In the chemical formula 1, ns is the refractive rate of the beads, and nc is the refractive index of the filaments.
본 발명은 내부에 반사용 비드를 포함하는 고반사 칫솔모로, 상기 칫솔모는 길이방향과 수직한 단면을 기준으로 내측에서 외측으로 갈수록 비드 밀도가 증가하며, 하기 화학식 1을 만족하는 것인 고반사 칫솔모에 관한 것이다. [식 1](상기 화학식 1에서 n는 비드의 굴절률, n는 필라멘트의 굴절률이다.) |
