the pre-twist-resisting twist in the S twist direction on a second twist working surface, then the rest pre-twist in the S twist direction is continuously transmitted upwards, as the transmitted twist is in the S twist direction, namely the twist action of twisting from left to right, the left fiber in the second twisting triangular area is in a tensioned state under the pre-tension of the twist, the right fiber in the second twisting triangular area is in a loose state, the second twisting triangular area is in a right-biased asymmetric structure, and as the fiber strand output from the right
