Abstract
In order to improve the mechanical properties and spinning performance of luminescent nylon fibers, different proportions of graphene were used for melt spinning, and the best spinning process of graphene-doped luminescent nylon 150D/36F composite fiber was found. The effects of doped graphene on the mechanical properties, molecular structure and luminescent properties of luminescent nylon fibers were analyzed by means of electron microscope scanning, infrared spectroscopy, test instrument of long afterglow properties and monofilament strength tester. The experimental results show that the mechanical properties of the fiber are improved after graphene is doped into the luminescent nylon. Considering the luminescent properties and mechanical properties of the fiber, the comprehensive properties of the fiber are the best when the amount of graphene is 0.5‰.
