Abstract
The study of yarn structure and positioning of the constituent fibers to form a continuous strand has attracted the attention of many workers who have used an idealized helical structure as a basis for these studies. The existence of this structure has been criticized as being unuseful and not manufacturable. Studies of the actual arrangement of fibers in the yarn have been carried out and different theories explaining the behavior of fibers in the process of yarn formation have been given. In this paper, a study and comparison of these theories is carried out illustrating the agreement and controversy between them. The factors that affect the position of the fiber in the yarn are outlined and discussed with regard to fiber, yarn, and processing factors to assist those dealing with blended yarns. Suggestions are advanced for further, more funda mental studies.
