| Abstract: | In the compact spinning with lattice apron, twist distribution of the fiber bundle in the compact zone is influenced by the airflow. In order to study the twist change of the fiber bundle in the compact zone,a theoretical model was established and the twist was calculated based on the experimental parameters. Experiments were carried out to verify the theoretical model. Theoretical and experimental results show consistency. The study indicates that the twist distribution of the fiber bundle in the compact zone is related to the tension, the offset angle and the linear density of the fiber bundle. |
