   Not quite as bad as graphite, but approaching that state.    
      
   Once-upon-a-time dental floss was made from silk, and could be doubled or   
   tripled to make a reasonable, stretch-resistant cord. Silk, like nacre feels   
   smooth, to the touch, but creates considerable friction when tight - while not   
   being overly abrasive.    
   Today the crap is made, primarily, from PTFE, and is flat, not round. It is   
   also highly abrasive and will cut through soft aluminum pulleys and sheaves if   
   made tight enough not to slip. Since it has a very low surface area, and PTFE   
   is a naturally    
   slippery material, and because the surface is textured to catch tartar but   
   still slip easily, it is altogether nasty in that application. Not to mention   
   that as landfill, it can last hundreds of years. Worse, if burnt, the POC are   
   deadly to felines and    
   Avian species.
