The Study On Mechanism Of Self-Twist Spinning

As a new twist yarn spun. Self-twist spinning was very popular in the1970s and ’80s. Because self-twist yarn was big difference compared with the conventional ring on the yarn quality, and its products were mainly used in knitted wool. With the continuous development of textile technology, self-twist spinning show the advantages of productivity, production costs, energy consumption and human resources, to regain people’s attention. Self-twist spinning a breakthrough not only effectively reduce the cost burden of production, and also in terms of product innovation. Thus, in the fast fashion clothing is increasingly becoming consumer today, people continue to increase the demand for textiles, so self-twist spinning can greatly enhance the competitiveness of enterprises.Due to the unique self-twist yarn spun principle only applies spinning60mm more fiber, yarn have inevitable untwisted and twist irregularity. These are the problems to be solved. On the basis of previous studies, studies of self-twist spinning twisting mechanism. According to the motion characteristics of self-twister roll, given the rubbing roller, L1, L2’s differential equations. Gives the general solution of the twist of L2district. Using MATLAB simulation sine twisting, help analyze twist irregularity and untwisted zone length. For the ideal distribution of L2District twist, rubbing roller’s twisting the law is derived using MATLAB. Self-twist balance is an important issue. In this paper, from the point of view of energy conservation, minimum energy state is Self-twist spinning equilibrium. Obtained the relationship of the twist bundles of fibers and the twist of the self-twist yarns. Expression untwisted zone length. Analysis of yarn structure, discussed the fiber length of self-twist spinning. This paper analyzes the effects of self-twist spinning process parameters on the self-twist spinning twist. On the basis of these, discussed the possibility of self-twist spinning spin the cotton-type fibers. The traditional process is not suitable for spinning of cotton-type self-twist yarn.The purpose of this project is to study the theory of self-twist spinning spinning way, provide a theoretical basis for the optimization of the process, improve the quality of yarn. Expand self-twist spinning’s fiber range. Hope that self-twist spinning is also a very good development on cotton fiber length.
