Caffeine fabric can also be called coffee fiber.

The principle is that as long as the coffee grounds are heated to 160℃ to 180℃ for carbonization, the physical structure of the carbonized coffee grounds can be changed, and after treatment and stretching, they can become yarns.

The fabric woven with coffee grounds fiber yarn is easy to dry, especially resistant to ultraviolet rays, because the fabric fiber has the function of removing odor.
