Description

Indoor golf net of three-dimensional net structure

The present invention relates to an indoor golf net applied to the bottom of the golf practice range, and more particularly to a three-dimensional indoor golf net in the mesh structure of the Raschel structure.

Artificial turf is one of the specially used landscaping materials, and is a substitute for artificially made grass in the form of grass. Since it was first manufactured in the United States in 1956, it has been used mainly in sports fields. It can be used in indoor gardens where turf growth is not possible, or in outdoor areas facing the north side of tall buildings with very limited sunshine hours.

Currently, artificial turf is mainly installed in places where natural grass cannot be built (dome ballpark where natural light is closed, where concentration is concentrated, and where it is difficult to grow natural grass in climate). Although the initial construction cost is high, it is highly preferred because of its semi-permanent use, ease of maintenance, and even surface to be suitable for exercise.

Artificial turf can always maintain greenness and is easy to manage after construction without being restricted by environmental conditions. On the other hand, there is no seasonal feeling and texture is slightly lower than grass, and it has a disadvantage of fading over time. Since it was first adopted by the Astrodome indoor baseball field in Texas in 1966, it has been in the spotlight as an all-weather facility including a soccer field, a field hockey field, an indoor golf course, and various leisure facilities.

Nowadays, interest in golf for artificial turf has become a lot of interest in using artificial turf for indoor golf, which is used indoors, and many studies have been made on artificial turf for golf courses.

Conventionally, golf turf has been widely used as a product in which piles are formed of polyamide yarns having crimps on circular knitted fabrics (fiber bubble layers) in which polyester yarns are knitted with a Raschel base.

However, the conventional artificial grass for golf has a problem that the pile is composed of polyamide yarn having a crimp, etc., the lack of abrasion resistance of the pile, the draw strength is easily pulled out by the load applied from the outside.
