[0014] A kind of preparation method of viscose base zinc ion antibacterial fiber of the present invention comprises the following steps:
[0015] (1) Weigh 5~10g of dispersant with a concentration of 10g / L and add it to 18~21g of ZnSO 4 ·7H 2 O, 200~220g of Na 2 SO 4 and 110~120g of concentrated H 2 SO 4 The volume of the mixed composition is 1~2L in an acid bath, stir evenly to obtain a mixed spinning solution; the dispersant is mixed in HB-sy100, BYK-171, TiO 2 , SHMP, or spin-653 in any one.
[0016] (2) Oxidation-reduction reaction in coagulation bath: add 18-21g of ZnSO after 2-3 hours of reaction 4 ·7H 2 O. When the as-spun yarn starts to be stretched, raise the temperature of the coagulation bath to 60-65°C, then add a rotating rod to stir at 120-150r / min to accelerate the reaction, and gradually obtain the antibacterial finished fiber.
[0017] The combination of zinc ions and viscose fibers is mainly completed in the solution, and its essence is an oxidation-r...
Embodiment 1
[0022] The preparation method of the present embodiment viscose-based zinc ion antibacterial fiber, comprises the steps:
[0023] (1) Weigh 5g of dispersant with a concentration of 10g / L and add it to 18g of ZnSO 4 ·7H 2 O, 200g of Na 2 SO 4 and 110 g of concentrated H 2 SO 4 The volume of the mixed composition is 1L in an acid bath, and stirred evenly to obtain a mixed spinning solution; the dispersant is HB-sy100.
[0024] (2) Redox reaction in coagulation bath: add 18g of ZnSO after 2h of reaction 4 ·7H 2 O. When the as-spun yarn starts to be stretched, raise the temperature of the coagulation bath to 60°C, then add a rotating bar to stir and accelerate the reaction at 120r / min, and gradually obtain the antibacterial finished fiber.
[0025] Prepare the antibacterial quilt with the antibacterial finished fiber obtained in step (2): According to the mass ratio, 30% of the antibacterial finished fiber and 70% of the polyester fiber are opened and mixed, and passed thro...
Embodiment 2
[0028] (1) Weigh 6g of dispersant with a concentration of 10g / L and add it to 19g of ZnSO 4 ·7H 2 O, 200~220g of Na 2 SO 4 and 115 g of concentrated H 2 SO 4 The volume of the mixed composition is in an acid bath of 1.5L, and stirred evenly to obtain a mixed spinning solution; the dispersant is TiO 2 .
[0029] (2) Redox reaction in coagulation bath: add 19g of ZnSO after 2.5h of reaction 4 ·7H 2 O. When the as-spun yarn starts to be stretched, increase the temperature of the coagulation bath to 63°C, and then add a rotating rod at 140r / min for stirring to accelerate the reaction, and gradually obtain the antibacterial finished fiber.
[0030] Prepare the antibacterial quilt with the antibacterial finished fiber obtained in step (2): According to the mass ratio, 35% of the antibacterial finished fiber and 65% of the polyester fiber are opened and mixed, and passed through the nozzle at the entrance before heat setting, with 5Kg / cm 2 Spray the white latex glue with a so...
