In order to further understand the relationship between twisting method and yarn structure,and to develop yarns with ideal structures,the spinning principles,twisting methods,yarn structures,and yarn properties of different spinning technologies were reviewed.The advantages and disadvantages of different yarn structures were analyzed,and the effects of twisting method on yarn structure and the relationship between yarn structure and yarn properties were further elucidated.The characteristics of ideal yarn structure were summarized,and the future development trend of yarn structure was anticipated.It was concluded that the difference of twisting mechanism leads to the difference of yarn structure,and the yarn structure affects the yarn quality.In order to further improve the yarn quality,we should start from the perspective of innovative twisting mechanism,so as to develop the ideal yarn structure.
