preparation example Construction

[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...

Abstract

The invention relates to a preparation method and application of viscose-based zinc ion antibacterial fibers. The preparation method disclosed by the invention comprises the following steps of: (1) weighing 5-10 g of a dispersing agent with the concentration of 10 g/L, adding the dispersing agent into an acid bath with the volume of 1-2 L, which is formed by mixing 18-21 g of ZnSO4.7H2O, 200-220 gof Na2SO4 and 110-120 g of concentrated H2SO4, and uniformly stirring to obtain a mixed spinning solution; and (2) carrying out oxidation-reduction reaction in a coagulating bath, namely adding 18-21g of ZnSO4.7H2O again after the reaction is carried out for 2-3 hours, heating the coagulating bath to 60-65 DEG C when the nascent filament starts to be stretched, adding a rotating rod, and carryingout stirring acceleration reaction at 120-150r/min to gradually obtain the antibacterial finished fibers.

Description

technical field [0001] The invention relates to a preparation method of fabric fibers, in particular discloses a preparation method of viscose-based zinc ion antibacterial fibers. Background technique [0002] Nowadays, people's education level is generally high, and they have extensive and unique cognition and requirements for various products. Home textiles occupy a large area of ​​textiles. Products, etc. are essential elements to create a warm home style. Not only do they have practical value, but products with multiple functions will have broad development space and will better meet the needs of consumers. At present, antibacterial, deodorant, and aromatic home textiles have been continuously appearing in home textile expos and home textile markets of different brands, and are gradually integrated into consumers' consumption concepts. [0003] Viscose fiber is now widely used regenerated cellulose fiber, mainly by extracting pure fiber from cellulose raw materials that...
