摘要: A thread-wound golf ball includes a core having a center ball and a rubber thread layer and a cover. The cover is composed primarily of a thermoplastic polyurethane elastomer of an aliphatic and/or alicyclic diisocyanate. The golf ball is prepared by impregnating the rubber thread layer with a urethane dispersion and injection molding the cover over the treated core.

摘要: A thread-wound golf ball has a wound core consisting of a center with a diameter of 29-37 mm and a rubber thread layer with a thickness of 1.0-2.5 mm. A cover enclosing the wound core is of two-layer construction comprising a relatively soft inner cover layer and a relatively hard outer cover layer having a Shore D hardness of 55-65. The inner and outer cover layers combined have a thickness of 2.0-5.0 mm. This construction gives the golf ball an excellent scuff resistance when hit with an iron club, as well as an improved spin, feel, and flight performance upon a full shot with a driver.

摘要: A wound golf ball comprising a center, a thread rubber layer and a cover has a weight of 40-45 grams and a distortion of 2.6-3.6 mm under a load of 100 kg. The center has an outer diameter of 30-35 mm and a distortion of 1.6-4 mm under a load of 30 kg. The cover has a Shore D hardness Hd of 50-68 and a gage of 1.2-2.2 mm. A percent overall dimple volume Vr which is defined as the sum of the volumes of dimple spaces each below a circular plane circumscribed by the dimple edge divided by the volume of the ball satisfies: (0.985-0.002 Hd).ltoreq.Vr.ltoreq.(1.085-0.002 Hd). The ball launches at a greater launch angle and initial velocity upon driver full shots at low head speed, traveling a longer distance.

摘要: A wound golf ball in which a wound core consisting of a solid center and a thread rubber layer is enclosed with a cover has a surface hardness of 70-85 on JIS C hardness scale, and presents a contact area of 3.5-4.1 cm2 with the club face of No. 9 iron driven at a head speed of 35 m/s. The ball is improved in control and distance in that it receives a more spin rate upon approach shots, but a less spin rate upon driver shots.
