<p><P>PROBLEM TO BE SOLVED: To provide a string for a racket which is hard to undergo a change in property by environmental variations, extremely excels in a fibril-proof nature without spoiling the same ball controlling nature as a natural string, and is excellent as in the natural string in repellence, shock-durability and an extension nature, and a manufacture method therefor. <P>SOLUTION: The string for the racket consists of a polypropylene terephthalate monofilament with a diameter, which is 0.3mm or more and 1.5mm or less, and has initial tensile resistivity of 1.0-10.0N/tex and a load at the time of 10% elongation in a tensile test of 1.13 cN/dtex or less. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
