In this study, the damage of cotton yarn in high-speed warp knitting is studied by means of experimental analysisand finite element simulation. 60 s compact-spun cotton yarn was used as the experimental object, and experimental testswere carried out from the morphology characterization, mechanical properties, twist and hairiness index to analyze thedamage of cotton yarn during the let-off movement. The equivalent finite element model of cotton yarn was established tosimulate the force and damage of cotton yarn in let-off motion, and the experimental results were compared with each other. The damage model and cause of cotton yarn in high-speed warp knitting process can be obtained, which provides theexperimental basis and the theoretical basis for further study of cotton yarn warp knitting.
