Claims

exact text as granted — not AI-modified
1 . A tennis bass felt, which is covered on a core of a tennis ball, comprising:
 a base fabric formed of stretchy material; and   fibers fixed with the base fabric.   
     
     
         2 . The tennis ball felt according to  claim 1 , wherein
 the felt is needle felt formed by fixing the base fabric and the fibers together by a needle punch method.   
     
     
         3 . The tennis ball felt according to  claim 1 , wherein,
 the fibers are processed with a fiber softening agent.   
     
     
         4 . The tennis ball felt according to  claim 3 , wherein

         5 . A tennis ball comprising:
 a core; and   a tennis ball felt including: a base fabric formed of stretchy material; and fibers fixed with the base fabric, the tennis ball felt covering the core.   
     
     
         6 . A tennis bass felt, which is covered on a core of a tennis ball, comprising:
 a base fabric having a mesh structure which develops stretch property; and   fibers fixed with the base fabric.   
     
     
         7 . The tennis ball felt according to  claim 6 , wherein
 the felt is needle felt formed by fixing the base fabric and the fibers together by a needle punch method.   
     
     
         8 . The tennis ball felt according to  claim 6 , wherein
 the fibers are processed with a fiber softening agent.   
     
     
         9 . The tennis ball felt according to  claim 8 , wherein
 a main component of the softening agent is a polyimide type cationic surfactant.   
     
     
         10 . A tennis ball comprising:
 a core; and   a tennis ball felt including: a base fabric having a mesh structure which develops stretch property; and fibers fixed with the base fabric, the tennis ball felt covering the core.   
     
     
         11 . A tennis bass felt, which is covered on a core of a tennis ball, comprising:

         12 . The tennis ball felt according to  claim 11 , wherein
 the felt is needle felt formed by fixing the base fabric and the fibers together by a needle punch method.   
     
     
         13 . The tennis ball felt according to  claim 11 , wherein
 the fibers are processed with a fiber softening agent.   
     
     
         14 . The tennis ball felt according to  claim 13 , wherein
 a main component of the softening agent is a polyimide type cationic surfactant.   
     
     
         15 . A tennis ball comprising:
 a core; and   a tennis ball felt including: a base fabric formed of stretchy material and having a mesh structure which develops stretch property; and fibers fixed with the base fabric, the tennis ball felt covering the core.
