The present invention relates to a racket for tennis, badminton, squash and the like. In recent years, learning how to hit a ball quickly has become an important issue for players when playing tennis and the like. As one means of achieving this, large rackets have appeared and become widespread in the case of tennis, but the conventional rackets with a diameter of 1.4 mm to 1.5 mm cannot cope with the high speed of hitting the ball, so The appearance of thin gauge guts is desired. However, making the gauge thinner than the conventional diameter will not only reduce the strength of the gut, making it unable to withstand the tension when tensioned to the racket, but also the batting force, making it difficult to realize. It was hot. The present invention has been made in view of this point, and an object of the present invention is to provide a gut that is of a thin gauge type but has high strength. Therefore, the feature of the present invention is that, in a gutt having a structure in which a large number of outer layer yarns made of thin synthetic resin monofilament are wound and bonded around a gutt made mainly of synthetic resin monofilament, The resin monofilament is made of a polyamide resin containing whiskers of silicon carbide or potassium titanate, and the aspect ratio of the whiskers is set to 30 to 300, and the average fiber length is set to 10 to 200 μm. . Hereinafter, the present invention will be explained in detail based on drawings showing examples. The figure is a cross-sectional view of a gutt showing an embodiment of the present invention. In the figure, 1 is a core body made of a thick synthetic resin monofilament, that is, the gutt main body, and 2... are wrapped around the gutt main body 1 and bonded. The outer layer consists of many thin synthetic resin monofilaments. Therefore, the gutt main body 1 and the outer layer yarn 2...
The gut 3 is made up of, and in the example shown, the outer layer yarn 2
A resin coating 4 is applied to the entire outer periphery from above. Specifically, the synthetic resin monofilament that is the gutt main body 1 is made of polyamide resin, and the polyamide resin contains whiskers, and the filled whiskers have an aspect ratio of 30.
~300% high strength single crystal fiber. For example, potassium titanate whiskers (KzO・nTiOz (n is 1
(above)) and silicon carbide whiskers (SiC).
Teismo (manufactured by Otsuka Chemical Co., Ltd.) is suitable for the former, and Toka Whiscar (manufactured by Tokai Carbon Co., Ltd.) is suitable for the latter.
The table shows the physical properties of Teismo and Toka Whisker.
