Nano carbon materials are attracting a great deal of attention, and a new material diamond nanothreads (DNT) is discovered in 2014. We aim to develop new superior materials by braiding DNT. On the other hand, Kuimihimo is one of the traditional Japanese culture. It is a technique to make beautiful patterns by knitting threads or to make a sturdy thread. Therefore, we just think of combination the latest material with Japanese traditional technology. Using molecular dynamics methods, we analyze the braiding of three DNTs and do the tensile test for them. As a result, we finds that energy increase and oscillate when creating a braided structure. The differences in the arrangement of three DNTs affect the stress-strain relationship. Furthermore, we find in the stress-strain diagram that the breaking strain is larger with decreasing the number of rotation per unit length.
