Problems solved by technology

[0003] But, the processing and manufacturing method of existing dental floss makes the cross-section of the thread body of the processed dental floss all be oblate rectangle shape or oblate shape, the shortcoming of this kind of dental floss is that the dental floss is in the tooth gap The elastic effect is relatively slow, and the cleaning surface is small. When there is a big difference between the teeth that are not neatly arranged and the gaps between the teeth, the tooth surface cannot be cleaned well. In addition, the taste is not satisfactory, and the existing dental floss is also strong. not high enough

Embodiment Construction

[0016] A polytetrafluoroethylene dental floss of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] see figure 1 , a polytetrafluoroethylene dental floss of the invention comprises a thread body 1, the thread body 1 is a microporous polytetrafluoroethylene film cut by a film splitting blade and then formed by a "V" shaped groove The forming die is rolled up and stretched to form a "ひ" shaped wire body in cross section, which is cut by a microporous polytetrafluoroethylene film through a film splitting blade and then formed by a "V" shaped groove. The width of the wire body formed in the shape of "ひ" is 2.0-2.2 mm in cross-section after being rolled up and stretched by the forming die. The thickness of the wire body formed in the shape of "ひ" in the cross section after being rolled up and stretched by the forming die with "V" shape groove is 50-65 μm. The polytetrafluoroethylene film with micropores is passed...

Abstract

A polytetrafluoroethylene dental floss comprises a floss body and is characterized in that the floss body is formed by the process that a polytetrafluoroethylene film provided with micropore is split by a film splitting blade and then is rolled up and stretched by a forming die and the transverse section of the floss body is in 'hi' (a Japanese hiragana) shape. The polytetrafluoroethylene dental floss of the invention is quick is the effect of degree of tightness when the floss body enters into slit between the teeth, is convenient to enter the slit between the teeth, and contact area of the floss body for cleaning teeth is large and is improved by 50-60% than that of the existing dental floss. The polytetrafluoroethylene dental floss can be used for cleaning teeth, repairing teeth and teeth health protection in hospitals and families.

Description

Technical field: [0001] The invention relates to a tool for cleaning teeth, in particular to a polytetrafluoroethylene dental floss. Background technique: [0002] Dental floss was originally used as a dental instrument, and later people found that it can not only remove food debris, but also be used to remove dental plaque and soft tartar in the gaps between the teeth, and the results are very effective. Therefore, since the 1980s, developed countries such as Europe and the United States have taken the lead in improving dental floss to the market. The use of dental floss is the most effective way to remove the impaction between the teeth and eliminate the pain caused by the teeth. , Dental floss can easily reach the narrow gap between teeth that are difficult to reach by brushing, rinsing and flossing, remove food residue, plaque and soft tartar between teeth, clean teeth, and use dental floss to stimulate around the teeth through massage gums, increase the blood circulati...
