Description
Technical field
The present invention relates to oral care implement field, in particular to a kind of compound tartar-removing toothbrush silk and its preparation
Method.
Background technology
Since ancient times, cleaning of the people for tooth and health just pay special attention to, in the world many time-honoureds have with
Spray or spile rubbing tooth carry out clean way, and another common clean method is then to rub tooth with sodium bicarbonate
Tooth.
Shown according to the data that U.S. dentist learns, first toothbrush is to be invented by bright filial piety ancestor in 1498 in the world, is
Short hard bristles hair is injected one the easy structure toothbrush formed on bone handle.The traditional method of west cleaning tooth is then
It is at least to have been occurred using cloth waste rubbing tooth, this method from ancient rome era.The blank of modern toothbrush is in the 17th century
Occur, be just widely current in 19 reality.Du Pont chemical industry in 1938 release the toothbrush that animal bristles are substituted with synthetic fibers, first
Toothbrush also the same year listing of bristle is done with nylon yarn.
At present, common tooth brush monofilament is mainly standby by nylon or four methine ester resin-made of poly terephthalic acid, main point
For soft, medium, hard three types, also there are some toothbrushes to carry out rounding processing for the end of tooth brush monofilament, so that in the process brushed teeth
In gum is massaged.Toothbrush often coordinates toothpaste to use, and in order to improve the effect that cleans one's teeth, grinding is often added in toothpaste
Particle, however, this still can not play the role of effective cleaning for tartar such as plaques.
In order to improve the effect that cleans one's teeth, certain exploration and effort are also made that in the prior art, such as increase in tooth brush monofilament
Add other compositions to improve its hardness, but, on the one hand, the increased filler of institute is mostly that matrix is covered, it is difficult to which playing should
Effective, on the other hand, the hardness of filler is relatively low, and for tartar, the particularly dirt such as plaque, color stain is difficult to remove.
In view of this, it is special to propose the present invention.
