What are Karate Belts Made of?

Karate is a form of martial arts that involves discipline, strength, and agility. As in many martial arts, karate has a ranking system based on the skill level of the practitioner. These ranks are symbolized by different colored belts. But what are karate belts made of? Let’s dive deeper into the history and materials used in karate belts.

History of Karate Belts

The origin of the colored belt system in karate goes back to the 19th century when Jigoro Kano, the founder of Judo, created a ranking system based on different colored belts. Later, this system was adopted by many other martial arts, including karate.

The earliest form of karate belts was simply a white belt that was often not even worn. Gradually, colored belts were introduced to symbolize the progress of the student. The belt ranking system in karate starts with white and ends with black, with varying colors in between.

Materials Used in Karate Belts

Karate belts are made of different materials, depending on the preference of the student or the instructor. The most common materials used for karate belts are cotton, polyester, and silk.

Cotton is a very common material for karate belts. It is lightweight, durable, and affordable. It is also easy to wash, which is crucial in a sport where the belts are often worn during rigorous training sessions.

Polyester is another material used for karate belts. It is also lightweight and durable, and it has the added advantage of being resistant to wrinkles and creases. Polyester belts are often made with a shinier material, which gives them a unique look.

Silk is the most luxurious material used for karate belts. It is soft and smooth, and it has a unique lustrous shine. It is also more expensive than cotton and polyester, which makes it less common.

The Color System of Karate Belts

As mentioned earlier, the color of a karate belt is an indication of the skill level of the practitioner. The most common color system for karate belts is:

– White belt – symbolizing purity and innocence, a beginner without any knowledge of karate.
– Yellow belt – symbolizing the first rays of sun and the growth of the seed, grasping the basics of karate.
– Orange belt – symbolizing the full of energy and enthusiasm, a period of growth and development in karate.
– Green belt – symbolizing growth, maturity and stability, advanced level of knowledge in karate.
– Blue belt – symbolizing the sky and the infinite possibilities that await, advanced level of understanding and knowledge in karate.
