Benefits of technology

[0012]As described above, according to the present invention, by providing a metal mesh layer having a predetermined wire diameter and a predetermined mesh count between the core and the cover, the golf ball is allowed to appropriately flex, and the golf ball is allowed to have an

Problems solved by technology

The predetermined ionomer resin currently used in a golf ball as described in Japanese Patent Application Publication No. 2013-220353 is a material having superior resilience and durability; however, when an ionomer resin having a higher resilience was used to satisfy a demand for further lower spin rate, there occurred a problem in that the golf ball produced had significantly poor durabil

examples

[0046]The golf balls of Examples and Comparative Examples having the constitutions shown in Table 1 were prepared, and the tests for measuring the performances of the prepared golf balls were performed. The compositions of the materials of the cores shown in Table 1 are shown in Table 2, and the compositions of the materials of the intermediate layers and the covers are shown in Table 3. It is to be noted that the mixing amounts of the individual components in Table 2 and Table 3 are represented in terms of parts by weight. The metal mesh layers of Examples were all made of the same metal, stainless steel. In addition, in all of Examples and Comparative Examples, the covers having the same dimple arrangement were formed. In addition, each of the golf balls was prepared by regulating the core composition in such a way that the deflection hardness was 2.5 mm, the outer diameter was 42.7 mm, the weight was 45.4 g, and the USGA initial velocity was 77 m / s.

Abstract

The present invention provides a golf ball capable of achieving a further decrease of the spin rate in the driver shot, and capable of more improving the flight distance, while maintaining high durability. The golf ball 1 of the present invention includes a core located in the center of the golf ball, a cover located outside the core and having a plurality of dimples on the surface thereof, and a metal mesh layer located between the core and the cover, wherein the metal mesh layer has a wire diameter falling within a range from 0.01 to 0.5 mm, and a mesh count falling within a range from 16 to 1000.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This Application claims priority from Japanese Patent Application No. 2017-245169 filed Dec. 21, 2017, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to a golf ball, and more specifically, to a golf ball with further improved flight distance in a driver shot, while maintaining durability.[0003]In order to improve the flight distance of a golf ball in a driving shot, it is advantageous to reduce the spin rate of the golf ball in the driver shot. As a structure of a golf ball to reduce the spin rate, for example, Japanese Patent Application Publication No. 2013-220353 states that by using a predetermined ionomer resin, as a material of a cover of a golf ball and an intermediate layer between a core and the cover of the golf ball, the resilience of the cover or the intermediate layer is improved, and accordingly the spin rate of the golf ball in the driver shot can be s...
