Preparation method and application of polyester staple fiber with deodorizing and antibacterial functions

This invention relates to the field of functional fiber technology, specifically to a method for preparing polyester staple fibers with deodorizing and antibacterial functions. The method includes preparing hydroxyl-loaded polyester masterbatch, preparing polyester fibers and grafting them, and post-treatment. This invention prepares hydroxyl-rich polyester masterbatch by adding high-temperature resistant hydroxyl-rich nanoparticles to polyester powder, and then adds the hydroxyl-rich polyester masterbatch to the spinning of polyester staple fibers. This increases the number of active hydroxyl groups on the surface of the polyester fibers, solving the problem that polyester itself does not have active groups and cannot be directly grafted onto the surface of pure polyester fibers. The active hydroxyl groups of modified cyclodextrin undergo nucleation and addition reactions with isocyanate groups, replacing high-temperature esterification and radiation crosslinking reactions, resulting in low energy consumption and environmental friendliness. The desealing temperature of the water-based end-capped polyisocyanate is consistent with the drying and relaxation setting temperatures in polyester staple fiber production, triggering the nucleation and addition reaction and solving the problem of side reactions caused by excessively active isocyanate groups.
