Abstract (en)
[origin: US4339499A] A string for the stringing of rackets, bows, musical instruments and the like which has a thread-like structure of polyvinylidene fluoride. The string is obtained by extruding a rod of polyvinylidene fluoride at a melt temperature of the polyvinylidene fluoride, cooling the rod at a temperature between 60 DEG -150 DEG C., and then axially stretching the rod at this temperature following by cooling the rod to room temperature and thereafter cold-stretching the monofil. The string is characterized by an elasticity that approaches that of natural gut string.
