Document Type and Number:
WIPO Patent Application WO/2020/138915
Kind Code:
A1
Abstract:
The present invention relates to branch-type bristles and a manufacturing method therefor. More particularly, the present invention relates to bristles comprising a sheath unit and core units having different bending strengths from each other when manufacturing filaments of a uniform size by using a polymer component forming the sheath unit and the core units. The present invention provides branch-type bristles which do not damage the inside of a mouth by being softly bent due to the sheath unit having low bending strength and have an excellent cleaning force due to the core units of various thicknesses having high bending strength.
