Embodiment Construction

[0023]The invention will be described below more detailedly. A tennis ball felt of the invention is formed by fixing a base fabric and fibers together. In the invention, in case that the base fabric is formed of stretchy material, examples of the stretchy material can include stretchy polyurethane, polyethylene terephthalate, nylon, a mixture of polyurethane and polyethylene terephthalate, a mixture of polyurethane and nylon, a mixture of nylon and polyethylene terephthalate, a mixture of polyurethane, nylon and cotton, and synthetic rubber. The most preferable material of these materials is, from points of excellent stretch property, and suitable thickness and weight, polyurethane.

[0024]Further, in case that the base fabric having the mesh structure which develops the stretch property is used, examples of the above mesh structure can include the structure shown in FIGS. 1A and 1B. In a mesh structure 20 shown in FIG. 1A, each mesh 22 is hexagonal; and in a mesh structure 30 shown i...

Field of the Invention[0002]The present invention relates to a felt used for an outer surface (melton) of a tennis ball and a tennis ball using the felt, and more particularly to a tennis ball felt which has less occurrence of creases at the time of forming a tennis ball and a tennis ball using the felt.[0003]2. Description of the Related Art[0004]As a tennis ball, as shown in FIG. 3, there is used what includes a core 10 and a felt 12 covered on the core. Usually, the core is formed of rubber in a spherical shape, and the felt is substantially gourd-shaped. Two sheets of felt are adhered to the core with a rubber adhesive. In FIG. 3, reference numeral 14 represents a joint between two sheets of felt where the above rubber adhesive is exposed.[0005]As the above-mentioned tennis ball felt, a woven felt or a needle felt is used (refer to JP-A-2003-154037). The woven felt, in which a surface of a woven fabric is fluffed up, is made by subjecting a raw fabric to raisi...
