Embodiment Construction

[0014] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Please combine figure 2 As shown, a kind of PTFE dental floss provided by the present invention comprises a thread body 1 which is formed after the expanded PTFE film with micropores is cut by a membrane splitting blade and rolled up and stretched by a diamond-shaped forming die. The cross-section is similar to a rhombus-shaped line body, changing the original "hi"-shaped line body, so that the two upper ends of the "hi" shape are respectively connected with extensions, and the upper ends of the two extensions are both towards the line body 1 The longitudinal centerlines of the wires are close together, so that the cross-section of the wire body is set in a rhombus shape.

[0016] Preferably, the wire body 1 and the extension section are made of expanded PTFE microporous film material, which has good elasticity, and c...

Abstract

The invention discloses a PTFE (Polytetrafluoroethylene) dental floss, which comprises a floss body, wherein a cross section of the floss body is in a V shape; two upper end parts of the V shape of the floss body are connected with an extension segment respectively; the upper ends of the two extension segments are both drawn close towards a longitudinal center line of the floss body, so that the cross section of the floss body is arranged in a rhombic shape; the floss body and the extension segments are all expanded PTFE microporous membranes. According to the PTFE dental floss, the floss bodyof the dental floss can be enabled to have a favorable rebound rate, and a dental gap is better cleaned.

Description

technical field [0001] The present invention relates to tooth cleaning implements, more particularly, relates to a kind of PTFE 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 its effect is 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 cir...
