Single core single layer fiber
It is the most popular nylon string cross-section structure today-most of the "imitation bowel strings" are single-core single-layer fiber structures. The biggest advantage of this string is that the pounds are not easy to decay, and the "brittle" feel of the ball is close to the natural bowel string. The texture and thickness of nylon's inner core and outer fibers will affect the hitting and comfort of the tennis line.
Single core multilayer fiber
Similar to the performance of a single-core single-layer fiber tennis line, but the durability and ball-eatability are better.
Multi-fiber
This string is a bunch of extremely thin synthetic fiber wires twisted together to form a string, the structure is similar to a natural bowel string. This nylon multi-strand structure is superior to the structure with an inner core in the comfort of shock absorption, and the ball feel is similar to a natural bowel string. At the same time, because this string is soft and comfortable when hitting, it is more suitable for players who have tennis elbows but cannot afford natural bowel strings. However, this kind of string is like a natural bowel string. It will cause damage to the ball and may cause the tennis line to split, so its life span is between the natural bowel string and the core composite string.
Multi-fiber single core multi-layer
A large core is composed of multiple thinner multi-fiber inner cores and is wrapped with one or more layers of fibers on the outside. This results in comfort similar to multi-fiber strings, but more durable.
Rough
This string wraps one or more rounds of filaments around the entire body of the string, or embeds the filaments in the outer layer of the string, thereby increasing the roughness of this tennis line, thus increasing the time when the tennis line hits the ball The friction against the ball makes it easier to hit the spinning ball.
Synthetic materials
The strings of different materials are combined together, and through the combination of inner and outer tennis balls of different materials, the advantages of different materials will be exerted as much as possible. Today, many tennis strings use this synthetic material structure
Single strand structure
Durability is good and the price is cheap. But this tennis line feels average, and the pounds tend to decay. It is recommended to add 3-5 pounds when stringing this tennis string to compensate for the loss of pounds.
Complex string structure
The polystring structure mentioned here does not refer to the cross-sectional structure of a tennis string, but a string-penetrating structure. Usually, a stronger string is worn on the vertical string, and then a nylon string or a natural bowel string with better feel is worn on the horizontal string. Such a string-penetrating structure is not only durable, but also has a good ball feel.
