Study of the Formation of a Dense Structure of OE Yarn

Аннотация

This article is devoted to the formation of a OE yarn uniform in structure, which is examined by studying the features of the formation of a fibrous ribbon from fibers of finite length. For this, the structure of the yarn, depending on the maximum width of the ribbon, is divided into free, dense and overlapping structures. The conditions conducive to the formation in the groove of the rotor of the fibrous ribbon of the maximum width, from which the yarn of a dense structure is obtained, which ensures the best quality of the yarn. The factors affecting the formation of the ultimate width of the fibrous ribbon in the trough of the rotor are studied. These factors are twist, linear and specific density of the yarn, the length of the processed fiber, the diameter of the rotor. The dependences of changes in the limiting width of the fibrous ribbon on these factors in combination with other factors are determined. It has been established that the maximum width of the fibrous ribbon is most influenced by twisting of yarn and the speed of the rotor. The least influence is exerted by the length of the fiber and the diameter of the rotor, which is recommended to take into account when developing OE yarn from fibers of finite length.
