POLYTETRAFLUOROETHYLENE FIBER
专利汇可以提供POLYTETRAFLUOROETHYLENE FIBER专利检索，专利查询，专利分析的服务。并且A PTFE fiber that is adapted to be sewn at high speeds. The fiber has a toughness greater than about 0.36 grams per denier (g/d). A range for the toughness is from about 0.36 to about 1.01 g/d, with a preferred range being from about 0.50 to about 0.80 g/d. The toughness of the inventive PTFE fiber is most preferably about 0.60 g/d. The inventive fiber has a peak engineering stress greater than about 1.6 g/d and a break strain greater than about 15.5 percent. A preferred range for the peak engineering stress is from about 3.0 g/d to about 5.0 g/d, and a preferred range for the break strain is from about 20 percent to about 50 percent. Most preferably, the peak engineering stress is about 4.4 g/d, and the break strain is about 24 percent. In another aspect, this invention provides a process for making a fiber that involves providing a PTFE fiber and heating the PTFE fiber to a temperature of from about 300 DEG C to about 500 DEG C, while overfeeding the PTFE fiber at an overfeed of up to about 70 percent. A preferred range for the temperature is from about 350 DEG C to about 450 DEG C, and a preferred range for the overfeed in the overfeeding step is from abut 10 percent to about 20 percent. Most preferably, the temperature in the heating step is about 400 DEG C and the overfeed in the overfeeding step is about 15 percent. The PTFE fiber may be used as a filament for an improved dental floss, and is also suited for an improved bearing material.，下面是POLYTETRAFLUOROETHYLENE FIBER专利的具体信息内容。
