摘要： A tennis ball comprises a hollow, spherical rubber ball (2) and a felt coating (4) attached thereto by an adhesive (3), the felt coating (4) being cut out from a felted fabric manufactured by knitting a circularly knitted high-pile fabric and laying in blended slivers of wool fibres and nylon fibres to produce a pile 5 needle-punching the circularly knitted fabric so that each pile fibre (5) is anchored at least at two parts thereof to the surface of the ground texture (6), and then forming a felted surface.

摘要： The tennis ball of semi-hard type having no pressure or low pressure, is suitable for the beginner and the old who periodically keep on exercising to enhance the health. The tennis ball is mainly made from nature rubber, synthetic rubber and flexible synthetic resin having high tensile strength. Such tennis ball is produced by press molding and unifying the outer surface of rubber core ball and inner surface of cover in die. Said outer surface has a thickness of 3.0-3.4 mm, a weight of 39-41 g, and inner surface has a thickness of 3.0-3.5 mm, a wight of 9-11 g. In this case, hollow of ball is at no pressure or low pressure(less than 5 psi), outer diameter of the ball is 63-65 mm and total weight of the ball is 48-52 g. Meanwhile, rubber core ball is formed as follows; uniformly mixing rubber composition in roll and mixer; press molding the mixture to the die(for half shell) to form half shell; and press molding the produced half shell to the die(two core ball) to form hollow sphere.

摘要： The present invention relates to a gasket to shield electronic apparatus from electric and electromagnetic waves and to a method for preparing the gasket, wherein the gasket is made of a conductive polymer elastic body. More particularly, an elastic body itself or an elastic body laminated with conductive fabric or metal film is punched to make holes, then a conductive material is applied thereto by dipping (filling) and coating to reduce surface resistivity and volume resistivity, and as a result, a gasket having impact and vibration absorption properties and conductivity is prepared.

摘要： A napping cloth for tennis ball of which the blending ratio of wool is very low was manufd. by 4 steps. (1)Weaving stain fabrics with cotton/polyester fiber & wool/nylon mixed fiber, as warp and weft, resp.; (2) napping by combing with a pile roller in direction of fabrics and flocking with counter pile roller in an opposition direction; (3)Bleaching and dyeing with acid, acidic mordant and mordant dye mixing with accelerating agent and retarding agent, (4) punching process by needle puncher.
