  • String of a vinylidene fluoride synthetic resin composition
    Patent number: 4382358
    Abstract: A string for the stringing of rackets, bows, musical instruments and the like has a thread-like structure comprising at least one monofil of a synthetic resin mixture containing 99-86% by weight of polyvinylidene fluoride and 1-14% by weight of at least one polyacrylate. The monofil is melt-extruded and is stretch-oriented to impart improved elasticity thereto.
    Type: Grant

  • String of a synthetic resin
    Patent number: 4339499
    Abstract: 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.degree.-150.degree. 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.
