Abstract

<P>PROBLEM TO BE SOLVED: To provide a ball-collecting sheet having good cushioning properties and durability while improving ball-collecting efficiency of a golf-training field, and reducing the reflection of sunshine. <P>SOLUTION: The ball-collecting Raschel sheet for the golf-training field is constituted of a sheet obtained by carrying out the punching finishing of a nonwoven fabric sheet 5 comprising wadding 4 of staple fiber of a synthetic resin on a sheet of Raschel fabric comprising chain-shaped stitch 1, insertion yarns 2 and connection yarns 3 with needles, impregnating the finished product with a resin, and subjecting the resultant product to dry finishing to fix the texture. The elasticity and cushioning properties of the Raschel sheet absorb the impact of the ball, and the reflection of the sunshine is reduced by the entanglement of the wadding of the staple fiber with the Raschel sheet in a feather shape. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention relates to a ball-collecting sheet laid on the fairway of a golf driving range, and needle punched synthetic resin short fiber cotton on a Russell knitted sheet to collect ball, cushioning, durability, and sunlight. It has improved reflection.

Conventionally, ball-pickup sheets for driving ranges have been used such as tufted loop artificial turf, needle punched carpets, and individual raschel sheets.

  In golf practice field collection, rolling the ball at a low gradient is important because it reduces the cost of collecting the ball, and increasing the cushioning effect has the effect of prolonging the ball. The ball-collecting sheet on the tufted loop artificial turf has a problem that, when the tissue is destroyed, fiber pills are formed, which deteriorates the ball-collecting efficiency. Other ball collecting sheets have problems such as reflection of sunlight and difficulty in seeing the landing point of the ball.

  Similarly, a synthetic resin short fiber cotton is punched with a needle on a Russell knitted sheet composed of monofilament, multifilament, split yarn, spun yarn and the like made of synthetic resin. Further, a resin is applied and dried to fix the sheet structure.

  The stretchability and cushioning properties of the Russell sheet absorb the impact of the ball, and the short fiber cotton penetrates into the structure of the Russell sheet, thereby reducing the unevenness of the sheet itself and lowering the rolling gradient of the ball. Furthermore, the reflection of sunlight is suppressed by the fact that short fiber cotton is entangled with the Russell sheet in a fluffy manner.

A double raschel knitted sheet having a thickness of about 5 mm and a surface having a space in which a needle can be driven, such as a honeycomb structure or a network structure, is used.
The material of the double raschel sheet is ideally good in weather resistance such as polyester and nylon.
Process a thin felt sheet with short polyester fiber.
A double raschel sheet is set on the felt sheet, and polyester short fiber cotton is punched with a needle.
Furthermore, a resin such as water-resistant SBR is infiltrated into the tissue, solidified by drying, and finished.

  Since the Russell ball collecting sheet according to the present invention can be industrially mass-produced, it has industrial applicability.
