1. Single core single layer fiber structure
This is currently the most popular nylon string cross-section structure-most of the "imitated bowel" is a single-core single-layer fiber structure. The biggest advantage of this line is that the pounds are not easy to decay, and the "crisp" feel of the ball is close to the natural gut. The texture and thickness of nylon's inner core and outer fibers will affect the hitting feel and comfort of the string.
2. Single core multilayer fiber structure
Similar to the performance of single-core single-layer fiber string, but the durability and ball eating are better.
3. Multi-fiber structure
This thread is a bundle of extremely thin synthetic fiber filaments twisted together to form a thread, the structure is similar to natural bowel thread. This nylon multi-stranded structure is superior to the structure with an inner core in the comfort of shock absorption and shock absorption, and the ball feel is similar to natural gut.
At the same time, because this string is soft and comfortable when hitting, it is more suitable for players who have tennis elbow but can not afford natural gut. However, this kind of thread is the same as natural bowel thread, and it will cause damage to the ball. It may also cause bifurcation of the string, so its service life is between the natural bowel thread and the cored composite thread.
4. Multi-fiber single-core multilayer structure
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 threads, but more durable.
5. Rough structure
This kind of thread wraps one or more turns of filament around the entire body of the thread, or embeds this filament in the outer layer of the string, thereby increasing the roughness of this string and therefore increasing the time when the string is hit. The friction against the ball makes it easier to hit the spinning ball.
6. Synthetic material structure
Combine the threads of different materials, and combine the different layers of the inner and outer layers to maximize the characteristics of different materials. Nowadays, many string shots use this synthetic material structure.
7. Single-strand structure
Durability is good and the price is cheap. However, this type of threading feels average, and the pounds tend to decay. It is recommended to add 3-5 pounds to this type of string to compensate for the loss of pounds.
