As the name implies, Synthetic Gut means "artificial gut string" and can also be called "imitation gut string". So what kind of string can be called artificial gut string?
We must first understand the structure and manufacturing process of real gut strings. Sheep bowel string is a goat's bowel fiber as thin as hair. After chemical treatment, washing and gluing, it is rolled into a thicker string, and then several thicker strings are wound into a complete string . Then apply a protective film on the surface.
The structure of this special craft chord is that the gut string has a unique sense of hitting. At the moment of hitting the ball, there is a "sucking" feeling, a pleasant sound and a stable and fast rebound, and, most importantly, its pounds change and degenerate very little. Therefore, many professional players and non-professional players are very fond of this tennis line. However, due to short life and high cost, it is difficult to use it frequently without strong economic strength.
As for the artificial gut string, is there a natural gut string? Some people hope that the artificial gut string can exceed the natural gut string. At least in terms of water resistance and longevity, artificial gut strings have been done.
But in terms of hitting the ball, the artificial ones are still slightly inferior. However, it can be said that it is very close. The problem lies in the "glue", too strong glue will stick all the thin strings together, and will not produce the "multi-filament" function; if the glue is not strong enough, it will cause air to enter, produce bubbles or split the strings But life is shortened.
Still, today's nylon has improved in quality, and the "multi-filament" forms multiple independent "strands" in the string, which are constantly improved in structure and technology, and many professional players are also using it. The stability of pounds has also been greatly improved.
Nowadays, there are many sheep-like gut strings on the market, that is, "coreless multi-filament" strings made of sheep-like farms. However, if you want the whole body to be close to the intestine, it is better to find a thinner one. Below 1.30mm in diameter, it feels good, and the ball control is also very good. However, if the string is "coreless" and thin, it will lead to shortened life. In addition, the coreless strings are usually displayed on the packaging structure.
Full string
You may already have a good racket, but now you need to know what to put on the racket. This is all about the tennis line. How important is the tennis line? Well, it is the only part of all tennis equipment that should touch the ball. In fact, if a good tempo is not good on the string, the effect is not as good as a bad tempo with a good pair of strings.
How to judge whether the string wearer is good enough?
The American Tennis Thread Association requires all string wearers to pass qualification certification. You can also listen to his questions, for example, he may ask you whether the control, strength, and comfort of the tennis line you use today are ideal, including how long it took before the tennis line was interrupted, the degree of rotation when hitting the ball, etc., You'd better rely on the questions he asked you to judge whether the string wearer is professional, rather than ask you questions to understand.
But if your string wearer is just asking "same string? Same pounds?" and not asking you about the details of playing, then you should think about it.
What type of tennis line should I use?
The standard of the tennis line depends on its thickness. Most of the tennis lines on the market are between No. 15 (the thickest) and No. 18 (the thinnest). The thinner the tennis line, the more you can eat and hold the ball. The better the hitting effect, the better the feel and control. But the thin string breaks too fast, so your best option is to start on the 17th. If you only interrupt the inner string in 10 hours, you can change to the 16th. But if the tennis line continues to be used for more than 25 hours, you can consider changing to No. 15.
How much pounds of pull should I give to the tennis line?
The manufacturer of the tempo will advise you how many pounds of pull should be applied, generally between 55 and 65 pounds. In order to achieve the ideal number of pounds, first take an average of the recommended number of pounds. After playing several times, you will face three possibilities:
You have obtained an ideal feel and balance of power, if so, this pound is very suitable for you;
If you feel that you have insufficient control, you need to increase your tennis line pounds by two pounds, so that you may hit the ball less deeply, but you gain more control; if you feel that you are not strong enough, then reduce your tennis Line pounds. It is important to remember that if your weight loss is too low, your racket will act like a trampoline and will obviously lose control.
How to judge whether the racket is properly worn?
Before you leave the professional store with the newly worn tempo, you need to check the following questions. If there is any discrepancy, you can ask the store to re-string for free for you.
Missing This phenomenon is that the horizontal string does not cross each vertical string. The phenomenon of missed tennis line will affect the use of rackets, which will also break the rules of tennis games.
Groove Tennis threads that bite each other will cause the string to break, and small grooves on the string are the first signs of this phenomenon. Obviously, a newly worn racket should not have grooves on the tennis line. When checking, move the horizontal string slightly away from the normal position to see if there is any gap in the vertical string.
Empty This is a very easy mistake to make. See if all the grommets on the frame have strings passing through. The holes will cause uneven pressure on the frame, making the manufacturer's guarantee of the quality of the beat meaningless.
Overlapping At the ten o'clock and two o'clock positions on the beat surface, the horizontal and vertical strings together occupy the grommet line hole. You will find that one string on the side of the frame is placed on the other string, which is the so-called overlapping cross. If the string pressed on it is higher than the outline of the frame, it will cause problems. When your racket scratches the ball to save the ball, the tennis line will be easily damaged.
Crack The player's worst nightmare is that his tennis line breaks his frame. If you find a crack on the racket, you should ask the string wearer to accompany you with a racket under the rights of consumers.
When should I change strings?
Aside from the fact that you have broken the string, the best indicator of whether the racket should be changed is to see how many pounds your tennis line has lost. The racket will lose 10% of its pulling force within 24 hours of just wearing the string. Subsequently, the pulling force will gradually lose, but the amount of loss will vary according to the string. Finally, the tennis line loses its elasticity and no longer has the function of catching the ball, and the racket loses control and strength.
You should always pay attention to this phenomenon and change strings in time. You can also replace your guess with a tensile test meter. Generally speaking, when your tennis line loses more than 30% of the tension, you need to re-string.
