摘要： PURPOSE: To allow a skier to make smooth skiing by providing strands whose surfaces are rough as having a number of irregular projections and recesses in small sizes, melting these strands so that they are attached together in a mesh form, and producing a netting of thermoplastic resin. CONSTITUTION: Foaming molding is made under the condition that the magnification of foaming is less than double, and strands 3, 4 are formed whose surfaces are equipped with a number of small projections 6 and small holes 7 and which include small bubbles 8 internally. The strands 3, 4 are arranged as intersecting one another and are melted and attached together in the intersections 5 so that a netting of thermoplastic resin is produced. This netting is laid in a skiing ground or on the floor of an artificial skiing facility. Even though the quantity of deposited snow is lesser and the netting is exposed on the snow surface to cause the sliding surface of ski plate to touch the netting, the ski edge bites into the netting at the time of turning with skis, and it is possible to perform smooth turning. This also ensures that a good heat insulativeness is obtained, the snow deposited on the netting is not easily melted, and that the melted snow is drained effectively.

摘要： PURPOSE: To enable comfortable ski sliding in a small amount of a snow fall by forming a thermoplastic resin made strand fusion-welded to each other in the net-like state to locate the upper end of the intersection point of the welded strands higher than a non-intersection point part. CONSTITUTION: A planking material formed of a thermoplastic resin made net and laid on a plane has the upper ends of intersection point of strands 3, 4 at a position higher than the non-intersection point part, i.e., the longitudinal strand 3 forming the upper surface of the net is in the highest position 6 at the intersection point part 5, and a non-intersection point part strand 7 between the intersection points 5, 5' is constructed to be bent downward and located lower than the upper ends 6, 6' of the intersection point parts. Thus, since only intersection point portion is constructed to be elevated, ski soles in ski sliding make few contact with the strands 3, 4, and accordingly, the contact with snow is increased. Even in a small amount of snow fall, sliding giving a feel approximating to that of snow surface can be enjoyed.

摘要： PURPOSE:To provide a driving range using light and highly strong chemical fiber with excellent strength, weatherproof and antiabrasion properties. CONSTITUTION:In a driving range with ball barrier nets having between a plurality of supporting pillars, featuring the ball barrier net is knitted into with- or without-knot net made of highly strong chemical fiber with the single fiber strength over 15g/d, elongation 3 to 10%, and the diameter of an internodal strand of net is lower than 1.5mm and the linear elongation of the internodal strand of net is 10.5 to 20%. A colored resin coating layer can be formed on the ball barrier net to improve the appearance and the floor face is composed of highly strong chemical fiber.
