Regenerated polyester material based luminescent fiber and preparation method thereof

The invention belongs to the field of textile chemical fibers, in particular relates to regenerated polyester material based luminescent fiber and a preparation method thereof. Currently a preparationmethod for preparing luminescent fiber from regenerated polyester and a product do not exist yet. The preparation method comprises the following steps that the regenerated polyester material is pretreated; the pretreated material is subjected to regenerated polyester slice preparation; a luminescence agent and a luminescence enhancement modifier are mixed, then a mixture is baked and activated toform composite powder, the composite powder is activated by a coupling agent, and then the composite powder and regenerated polyester slices are prepared into luminescent polyester master batch; andthe luminescent polyester master batch and the regenerated polyester slices are treated, and finally the regenerated polyester material based luminescent fiber is obtained. The production process is stable, the product quality
