ABSTRACT:
A string is provided which has been stabilized to retain its initial tension over a long period when strung in a racket, and which has a high ratio of tensile strength to modulus of Elasticity to cause the deflection of the string woven membrane to be almost linear with applied force. The string has a very low Modulus of elasticity to cause the region of the string in the vicinity of the ball impact point to stretch easily and provide a cup for the ball at the moment of highest string membrane deflection.
