In the present invention, what is particularly important is that the specially crimped composite yarn of the present invention has thick details alternately in the length direction, and different crimps between the thick portion and the details. It has a shape. Here, the difference in the crimped shape means that
It means that the size of the crimp and the number of crimps in the thick portion and the detail of the thick and small portions are clearly different. For example, in the thick portion of the thick and small portion, the diameter of the spiral crimp is large and the coarse crimp is small in the number of crimps. The term “crimp” means that the spiral crimp has a small diameter with a small diameter and a large number of crimps in detail. By adopting such a fiber shape, a fabric having not only a stretch performance but also a natural spanning feeling can be obtained from the composite crimped yarn.
