发明名称 Ball made of a leather-like sheet
摘要 The leather-like sheet for balls of the present invention comprises a fiber-entangled fabric and a porous surface layer disposed on the surface of the fiber-entangled fabric. The porous surface layer has a pattern formed by a plurality of outwardly projecting pebbles and valleys between the pebbles. A plurality of microholes having an average diameter of 5 to 100 mu m are formed on surfaces of the pebbles, but microholes are substantially not formed on surfaces of the valleys. The leather-like sheet exhibits a sufficient surface abrasion resistance and an excellent non-slip properties because of its high sweat-absorbing ability under wet conditions.
