Since the number of fibers of the low count yarn is large, the influence of the friction force generated by the first triangular groove 111 or the second triangular groove 121 on the yarn 5 evenness is relatively small, so that the stationary flat plate type twisting device 1 is selected, and for the high count yarn with the small number of fibers, in order to reduce the friction force generated when the first triangular groove 111 or the second triangular groove 121 restrains and controls the fibers and influence the yarn 5 evenness, the first triangular groove 111 or the second triangular groove 121 which rotates in a wheel type is selected, so that the fiber deterioration evenness caused by the friction of the first triangular groove 111 or the second triangular groove 121 is reduced, the geometric dimension of the first triangular groove 111 or the second triangular groove 121 is also selected according to different yarn counts, because the geometric shapes of the spinning triangular areas with different yarn counts are different, and the geometric dimension of the first triangular groove 111 or the second triangular groove 121 is also very important to be selected in a targeted manner.
Due to the dual functions of the twisting device 1 and the refocusing device 2, the spinning triangular space is artificially controlled, gravity is used for stopping twisting, the twist is slowly and gradually transferred upwards, the resultant yarn is slowed down, the fiber is gradually made into yarn 5 according to the designed route and state under the artificial intervention, and the gravity can freely move up and down according to the amount of the fiber when acting on the fiber, so that the effect of self-leveling the fiber is achieved, the structure with tight outside and loose inside is realized, namely, the hairiness is less, 5 yarns are dry, and the produced fabric has soft hand feeling.
The invention also provides a spinning process for twisting and reshaping the triangular area step by using gravity to restrain fibers, wherein after the roving is drafted by a drafting mechanism, fiber strands are output from a front jaw consisting of a front roller 3 and a front leather roller 4 and enter a twisting device 1 which is 3-15 mm away from the front jaw, the twisting device 1 folds the width of the fiber strands in the twisting triangular area and presses peripheral fibers to transfer to the inside of the strands, the fiber strands gathered by the twisting device 1 pass through a reunion device 2 which is 2-10 mm away from an outlet of the twisting device 1, the peripheral fibers are restrained and twisted into yarns 5, and then the yarns are wound on a spindle 6 through a yarn guide hook and a steel wire ring.
