Abstract

DC60 (25/02/48) A PTT toothbrush (polydrmethylene terephthalate) filament is provided where it has an acquired durability rate. New update Apart from the rate Improved durability This new toothbrush also offers an increased rate of use, better cleaning efficiency and a feeling of Better use of it In toothbrushes that use PTT filament, PTT filament has the Shrinkage in hot water 0.4% or less on the Curve shows the hysteresis obtained by measuring the elongation of the filament relative to the load. Where the filament is stretched out and The reverse filament has a T delta max elongation, where the difference between The burden during which it stretches and recovers Will have the most And that would be 50% or less of The maximum recovery rate, Tmax and filament had the greatest difference, the Fmax delta of the load at the same elongation rate. Between the loads at the time of stretching and returning with their greatest difference being 70% or less than the maximum load Fmax at the greatest elongation rate. And filament will have The elastomeric rebound rate at the elongation rate TO, which is 50% or more of the elongation maximum Tmax under load reduced to zero during the return and fila. The apartment will have an elongation elongation rate of 50% or more at a minimum. At the rate of elongation 25% of the maximum. In addition, the bristle holding area is 0.8 to 1.9 cm2 and the bristle adhesion density is 35 to 45%. PTT-based toothbrush (polydrmethylene terep Thalate), the filament will be provided, it will have the obtained durability rate.

Claims (6)

1. A toothbrush that contains Bristles where polyethylene terephthalate filament or where polyethylene terephthalate is the main component is introduced. Use as part or all of the bristles. Where it has the characteristics: the filament is made of polytrimethylene terephthalate or has Polytrimethylene terephthalate as the main component has a shrinkage rate of 0.4% or less in hot water. 2. Toothbrush, as stated in claim 1, where it has the characteristics: filament with T delta max elongation, where the difference Difference between the burden The moment when it stretches and returns Will have the most On the curvature of the hysteresis word obtained by measuring the elongation rate of the filament relative to the load, as this filament stretches out and returns itself. And where 50% or less of the elongation rate is greatest, T delta max is used as such a filament. That are made of polytrimethylene terephthalate or containing polyethylene terephthalate as the main component 3. Toothbrush, as stated in claim 2, where it is characterized as: the most different filament, Fmax delta of burden at the rate period. The same elongation between the loads at the time of stretching and restoring where the greatest difference is 70% or less of the greatest load Fmax at the greatest elongation rate. Will be used as Lamate said That are made with polytrimethylene terephthalate or containing trimethyl terephthalate as the main component 4. Toothbrush, as set out in any of Clause 2 or 3, where it has that characteristic; Filaments with elongation elastic recovery rate Which is the ratio Of recovery under an elongation that meets Elongation rate at TO under reduced load to zero during the return of the maximum elongation rate Tmax and where expressed by {(Tmax-TO) / Tmax} x 100 and where is 50% or More than it could be used as The filament That are made of polytrimethylene terephthalate or containing polytymethylene terephthalate as the main component 5. Toothbrush, as stated in claim 4, where the characteristic is: filament with an elongation elongation rate of 50% or more on the strands. Curve of the hysteresis value at a range that is at least at the The maximum elongation of 25% is used as such a filament made from polytrimethylene terephthalate or containing polytrimethylene terephthalate. Raphthalate is the main ingredient. 6. Toothbrushes, as stated in Clause 1 to 5, one of them is characterized as: A toothbrush consists of a brush head with a bristles of 0.8 to 1.5 cm2 and a density for Clings 35 to 45% of the bristles on the skin, stretching their bristles.
