    摘要: The present invention provides a thread-wound golf ball comprising a thread rubber ball prepared by winding thread rubber around a spherical solid center, and a cover enclosing the thread rubber ball therewith, which has a number of dimples of from 350 to 500 and a dimple volume rate of 0.76 to 0.9 percent, and wherein the solid center has an outer diameter of from 27 to 38 mm, a deformation under a load of 30 Kg of from 1.5 to 3.5 mm and a rebound, when dropped from a height of 120 cm, of at least 96 cm. The thread-wound golf balls of the present invention show good spin properties in addition to good restitution properties, resulting in improved travel distance.

    摘要: In a wound golf ball comprising a solid center (1), thread rubber (2), and a cover (3), the cover has a multi-layer structure including an outer layer (4) and an inner layer (5) having a higher hardness than the outer layer. The outer layer (4) is 0.4-3.0 mm thick, and it is formed of a first ionomer resin having a Shore D hardness of 40 to 55. The inner layer is formed of a second ionomer resin having a Shore D hardness of 55 to 68. The difference in hardness between the first and second ionomer resins is at least 5 in Shore D hardness. The ball affords improved spin and durability.

    摘要: A wound golf ball including a liquid center (4) in the form of a rubber bag (2) filled with a liquid (3), a thread rubber layer (5), and a cover (6). The filling liquid of the liquid center is a liquid having water-insoluble powder dispersed therein so as to have a specific gravity in the range of 1.08-1.70 and a viscosity in the range 1-6,000 centipoise at 23.degree. C. The water-insoluble fine particles are present in the range of 4-60% by weight of the liquid dispersion. By improving the filling liquid, the wound golf ball is increased in flying distance while maintaining its own controllability.
