Description
Technical Field
The utility model relates to a toothbrush, in particular to a toothbrush with mechanically sharpened polytrimethylene terephthalate bristles.
Background
The existing toothbrush generally adopts monofilaments made of high polymer materials as toothbrush bristles, the toothbrush bristles are made of high polymer materials such as nylon 66, nylon 610, nylon 612, nylon 1010, polybutylene terephthalate (PBT), polytrimethylene terephthalate and the like, the appearance of the toothbrush bristles is different due to different processing modes, and the toothbrush bristles are usually round-head filaments obtained by a mechanical rounding process and sharp-head filaments obtained by a chemical sharpening process. The mechanical rounding process is to rub the ends of the filaments on a rotating grinding tool to remove sharp corners of the ends of the filaments and obtain rounded ends, and the process can be performed before or after the toothbrush bristle planting process. The mechanical rounding process is usually used for processing nylon monofilaments, but not polyester monofilaments, because polyester monofilaments have high hardness, and toothbrushes using round-head polyester monofilaments as bristles have poor taste and are prone to damage teeth and gums, the chemical sharpening process is usually used for processing the polyester monofilaments. The round-head filaments cannot extend into the tiny tooth gaps between teeth due to the fact that the tail end of the round-head filaments is large in size, and the cleaning effect on the areas is not ideal. The chemical sharpening process is to soak the tail end of the filament in corrosive chemical solution and obtain the tip filament with a slender and tapered tail end through the chemical corrosion action. The production of tip filaments can produce large amounts of liquid contaminants that harm the environment. In addition, the chemical sharpening process is generally performed before the bristle-planting process of the toothbrush due to its harsh conditions. The pointed filaments, which are generally obtained by the chemical sharpening process, are not uniform in length and cannot be trimmed after the bristle-implanting process of the toothbrush, so that the bristles of the toothbrush manufactured using the pointed filaments are always uneven.
Disclosure of Invention
The utility model aims to solve the technical problem that the toothbrush is not enough for the prior art and provides a toothbrush with mechanically sharpened polytrimethylene terephthalate bristles. The utility model discloses the brush hair tuft of toothbrush adopts the polytrimethylene terephthalate preparation of mechanical sharpening to form, and the environmental pollution problem that the technology of chemical sharpening can be avoided to the technology of mechanical sharpening and the problem that the tip silk is highly different are compared in the toothbrush that adopts the monofilament of mechanical rounding as the toothbrush hair can clean the slot region better.
In order to solve the technical problem, the utility model discloses a technical scheme is: a toothbrush which mechanically sharpens polytrimethylene terephthalate bristles, characterized in that it has the following features:
the utility model provides a toothbrush of machinery sharpening polytrimethylene terephthalate brush hair, includes the brush holder and connects the brush head at the brush holder front end, plants the brush hair tuft that is formed by a plurality of brush hairs bunches on the brush head, brush hair tuft is whole or partly adopts polytrimethylene terephthalate to make, including cone portion and non-cone portion, and wherein cone portion is sharpened through machinery, and length is 0.4~2.5 mm, is located the end of brush hair.
The non-cone part is located in the middle of the bristles, and the diameter of the non-cone part is 0.10-0.25 mm.
The length of the cone part is 0.5-2.0 mm.
The length of the cone part is 0.5-1.0 mm.
The content of the polytrimethylene terephthalate in the bristle tufts is not less than 95%.
The bristle compositions of the bristle tufts are all the same or partially the same.
The bristles comprise polytrimethylene terephthalate bristles and one or more of nylon bristles, polyethylene terephthalate bristles or polybutylene terephthalate bristles.
The nylon bristles are one or more of nylon 612 bristles, nylon 610 bristles, nylon 6 bristles or nylon 66 bristles.
Compared with the prior art, the utility model discloses an effect and benefit are:
(1) the mechanical sharpening process can avoid the problem of environmental pollution of the chemical sharpening process and the problem of different heights of the sharp-pointed filaments;
(2) the tip yarn can be easily obtained by adopting the polytrimethylene terephthalate monofilament through a mechanical polishing process;
(3) toothbrushes using mechanically sharpened polytrimethylene terephthalate tip filaments as bristles can better clean interdental areas than toothbrushes using mechanically rounded monofilaments as bristles.
