The invention discloses a fancy elastic bamboo fiber wrap yarn and a processing method thereof.The wrap yarn is composed of core layer stretch yarn and bamboo fiber yarn wound around the core layer stretch yarn, and the wrap yarn is of a regular or irregular'point '-shaped or'knot'-shaped pattern structure; spindle tubes for winding outer wrapped yarn are placed on hollow spindles on the upper row of a creel of a common spinning frame, stretch yarn is placed on the lower row of the creel, the wrapped yarn is collected at a yarn forming bobbin through a yarn guide roller, a horn mouth of a traversing gear and a winding roller, the rotating speed and the unwinding rotating speed of bamboo fiber spindles are set to be constant, and the yarn feeding speed is periodically switched. The yarn feeding speed is low, the number of wrapping turns per unit length of the wrap yarn is large, the yarn feeding speed is high, the number of wrapping turns per unit length of the wrap yarn is small, the tension of the elastic co
