<p>PURPOSE:To make vibrations of a gut surface absorb in hitting a ball for preventing tenniselbow by using elastic fibers for at least a part of filament fibers of a plurality of filament fibers. CONSTITUTION:A gut 1 consist of a plurality of synthetic resin filament fibers 2 and elastic fibers 3 are used for a part of a plurality of the filament fibers, or the gut 1 consists of core component fibers 4 of filaments and cover component fibers 5 of filaments wound around the outer peripheral surface of the core component. In either case, a sheath part is formed of nylon filaments and a part of the fibers is made of elastic filaments 3 so that the core component fibers 4 and cover component fibers 5 may be fixed by adhesives 6. Preferably the elastic fibers are polyurethane fibers, polyester-polyether copolymer fibers and polyamide-polyether copolymer fibers.</p> |
