Non-toxic dyed FDY (Fully Drawn Yarn) paper tube

The utility model belongs to the technical field of paper tubes, and particularly relates to a non-toxic dyed FDY (Fully Drawn Yarn) paper tube which comprises an internal thread paper tube, an external thread paper tube is screwed in the internal thread paper tube, a covering mechanism is arranged on the outer wall of the internal thread paper tube, an activated carbon damp-proof layer is adhered to the inner wall of the external thread paper tube, and the activated carbon damp-proof layer is adhered to the inner wall of the internal thread paper tube. And the internal thread paper tube, the external thread paper tube, the covering mechanism and the activated carbon damp-proof layer jointly form an FDY paper tube main body. According to the non-toxic dyed FDY paper tube, the deformation resistance, the waterproof performance, the fireproof performance and the moisture resistance of the FDY paper tube main body can be well improved through the covering mechanism, so that the service life of the non-toxic dyed
