Background
In the textile field, a drafting system is formed by a lower pin, an upper pin, a leather ring, a roller, a leather roller and a cradle together to draft and control a roving strand. In the drafting zone, a part of the fibers are accelerated at a speed change point under the action of a drafting force, the other part of the fibers are not accelerated under the action of a holding force, the accelerated motion of the fibers forms a drafting process, and then the accelerated fibers are twisted into yarns after passing through a front jaw, so the state of the accelerated fibers directly influences the quality of the yarns.
Meanwhile, in the unit section of the roving strand, the more orderly and orderly the fiber arrangement is, the more easily the fiber arrangement is stably drafted, the better each index of the yarn is, and particularly the improvement on the fiber evenness is more remarkable. The phenomenon is that in the process of yarn formation, fibers are transferred inside and outside in the twisting triangular area, the fibers are twisted and cohered in the yarn main body, the stress directions of the fibers which are regularly arranged are consistent in the process, the transfer process is carried out stably and orderly, and then the yarn with better longitudinal uniformity is formed. Therefore, the guarantee of stable and orderly drafting of the fiber in the main drafting zone is a key factor for improving the quality of the finished yarn. To achieve this, one provides the lower pin as a T-shaped body consisting of a transverse upper part and a vertical lower part.
