Of course - Kyle Isenhart explained it all in the first article in the first Nylon Highway.
Since some ropes tend to become very stiff after extended use, everyone sooner or later ponders whether to use fabric softener on their rope. Softeners work by the action a Quaternary Ammonium Salts. These salts adhere to the furface [<-orig.American :-] coating. This coating is very slick and allows the fibers to slip past each other with very little friction. This lubricating effect increases the flexibility of the material which people interpret as being softer when in reality it is only more flexible. These ammonium salts have no harmful effect on nylon and the use of fabric softeners on rope is quite advantageous.
The softeners have other advantages. That portion which penetrates to the core of the kernmantle ropes lubricates the minute filaments and helps keep them from abrading on each other while the rope is flexing. The softener also forms a barrier between the rope's nylon fibers and dirt particles. ...
