The most comfortable badminton is the "Asia Dragon No. 6". The ball speed is moderate, the weight of the ball is just right, and it is relatively durable. It is best to pour a little water vapor into the barrel the night before playing, which can make the ball more durable and increase the speed of some balls.
RSL No. 5 ball speed is slightly faster, the weight of the ball is okay, the price is slightly cheaper, but it is relatively less durable.
In addition, Hangyu No. 2 is also good, durable, with good ball speed and weight.
The price of the Yanzi brand is cheap, and the durability is only so-so. However, I feel that the weight of the ball is too light, the ball cannot hit far, and it is very unpleasant to play.
There are also 75-79 Green. The larger the number, the faster the speed. Generally, 77 feels good.
I recommend using RSL6, which feels better when playing.
The following is an analysis of badminton:
Classification of badminton feathers (differences in raw material grades):
1. Goose feather material: Mainland China’s feathers are divided into three major industries District
Sichuan Mao: April to July every year
East China Mao: (Anhui, Jiangsu, Zhejiang), July to October every year
Northeast Mao : (Three Northeastern Provinces), October to December every year
Making easy-to-play, moderately weighted badminton balls, mainly Sichuan wool, and manufacturing durable, beautiful feather balls, mainly using Northeastern wool.
The one that suits you is the best, go and choose one!
2. Feather cutting rate: A duck has an average of about 16 feathers on its left and right wings.
A goose has an average of about 20 feathers on its left and right wings.
For competition level (A) and above, there are about 3-4 ducks on the left and right wings, and about 5-6 geese.
Standard level (B), left and right wings, about 4 for ducks and 4 for geese.
Standard grade (C), left and right wings, about 4 for ducks and 4 for geese.
A badminton requires 16 feathers arranged at the same angle to form a good ball with excellent flight. In addition, the appearance of the feathers is white and smooth, so it can be called a super badminton.
Classification of badminton heads
According to the materials used, there are three common types: hard plastic, foam plastic, and cork. The first two are mainly used for low-end entertainment. With badminton, the cost is lower and the performance is worse. Mid- to high-end badminton balls all use natural cork heads, and cork heads can be roughly divided into three categories: integral cork heads, composite cork heads, and recycled cork heads. Currently, there are two types of heads: one It is an all-cork ball head. Low-quality cork materials are easier to crack. The other type is a Taiwan fiber ball head and cork composite (man-made material). This kind of ball head has better strength.
The structure of the Taiwan fiber ball head:
The upper layer of the ball head is made of chemical fiber material about 13MM, and the lower layer is made of cork. There are three types of softwood in the lower layer:
1. Small-grained cork, with a hardness below Shore 60 (patented by Taiwan Chung Hwa Cork Factory);
2. Large-grained cork, hardness The hardness of 13MM solid cork (patented by Shanghai Chongming Island Cork Factory) is more than 60 on the Shore scale.
Judging from the use of the above three types of ball heads, the durability is much better than that of all-cork, because one of the main reasons is that the flat surface of the cork ball head will crack, and Taiwan Fiber There is basically no cracking in the ball head of the board. The latter two types of ball heads have a better feel. They sound crisper when hit, and they don’t stick to the racket. It is generally believed that small cork ball heads are not as good as the latter two.
There is a belief that composite cork - that is, Complexcork badminton - has a durability that is increased by more than 30.
The production cycle and durability requirements of badminton:
The growth cycle of a goose from hatching to slaughtering is generally 120 days. The sponge bodies are basically mature, so it will have certain benefits for the durability of badminton.
With the continuous advancement of science and the warming of the global climate, the growth cycle of a goose is currently only about 90 days, so it is definitely less durable than the 120-day growth cycle. The main reason is that the glial layer and sponge body of the hair stem are not mature enough. (Technology is feed improvement, climate is average temperature rising by 2-3 degrees).
How to make badminton more durable?
Prepare a bowl of boiling water that has been boiled for a while, and immerse the feather part of the badminton in the water for 2-3 minutes. Be careful not to let the water soak into the head part of the ball. The water temperature cannot be too low. If the water gets cold, it must be replaced in time. boiling water.
After soaking, take out the ball and dry it in the shade. Be sure to dry it in the shade before use. The feathers treated in this way have better toughness. As long as they are not directly hit on the hair of the ball, the durability of the ball will be improved a lot. Pay special attention to the fact that if it is not used within 5-6 days after treatment, it should be reprocessed. In addition, if you buy duck feather balls, their structure and strength are far inferior to goose feathers, and the treatment effect will be poor.
The reasons:
1. Duck feathers have more fat than goose feathers;
2. Duck feathers have very few sponges and are not easy to absorb water vapor, so the effect is not obvious. .
Badminton court standards
The badminton court is a rectangular court with a length of 13.40 meters, a doubles court width of 6.10 meters, and a singles court width of 5.18 meters. The width of each line on the court is 4 cm, and the measurement should be measured from the outer edge of the line. Court boundaries are best drawn in white, yellow or another easily identifiable color. According to international competition regulations, the minimum space above the entire court is 9 meters. Within this height, there must not be any beams or other obstacles, and there must be no obstacles within 2 meters around the court. There should be a minimum distance of 2 meters between any two juxtaposed courts. The walls around the court are preferably dark and must not be exposed to wind.
The standard badminton net is 6.10 meters long and 76 centimeters wide. It is made of high-quality dark natural or man-made fiber. The mesh size is between 15-20 mm. The upper edge of the net should be sewn with 75mm wide double-layer white cloth (made by folding it in half), and use a thin steel wire rope or nylon rope to pass through the interlayer, and hang it firmly between the two net posts. The standard net should be yellowish brown or grass green. The height of the net posts is 1.55 meters. Whether it is singles or doubles, the two net posts should be erected at the midpoint of the sideline of the doubles court. During official competition, the middle edge of the net must be 1.524 meters high from the ground, and the height of both ends of the net must be 1.55 meters. The ends of the net must be fastened to the net posts and there should be no gaps between them.
