Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of textile materials, and in particular relates to a perspiration-wicking and antibacterial functional fiber and a preparation method thereof. Background Art
[0002] With the advancement of science and technology and the improvement of people's living standards, people pay more and more attention to the comfort and health of wearing. Especially in hot summer and during strenuous exercise, the human body will produce a lot of sweat. If the sweat cannot be discharged by the fabric in time, it will not only cause the wearer to feel stuffy, but also breed a large number of bacteria and emit a pungent odor, causing serious harm to human health.
[0003] In the prior art, Lyle fiber is used as the base material to prepare functional fabrics with moisture absorption and perspiration. Lyle fiber is a regenerated cellulose fiber made from natural plant fiber by spinning. It has excellent moisture absorption and breathability, and can adsorb, diffuse and evaporate liquid sweat through the capillary effect inside and between fibers, thereby achieving the purpose of moisture absorption and perspiration. However, Lyle fiber itself does not have antibacterial properties, and copper ions with good antibacterial properties have poor complexing ability with Lyle fiber, which limits the application of copper ions in the antibacterial properties of Lyle fiber. Therefore, how to prepare functional fibers with both moisture absorption and perspiration and antibacterial properties is a technical problem that needs to be solved at present. Summary of the invention
[0004] The object of the present invention is to provide a perspiration-wicking and antibacterial functional fiber and a preparation method thereof, so as to solve the problems in the background technology.
[0005] The purpose of the present invention can be achieved through the following technical solutions:
[0006] A method for preparing a perspiration-wicking antibacterial functional fiber comprises the following steps:
[0007] S1. The Lylece fiber washed with deionized water and dried is placed in a sodium hydroxide solution, stirred and mixed for 10-20 minutes, and then washed and dried to obtain activated fiber; the hydroxyl groups on the surface of the Lylece fiber molecules are activated by the sodium hydroxide solution;
[0008] S2, adding activated fiber to sodium periodate solution, reacting in the dark at 40-50°C for 0.5-1h, cooling, adding excess glycerol, letting stand for 1h, centrifuging, washing, and drying to obtain oxidized fiber; using sodium periodate solution as an oxidant, oxidizing the hydroxyl groups on the surface of the activated fiber into aldehyde groups, and removing unreacted sodium periodate with excess glycerol;
[0009] S3. Add the modified antibacterial agent to the mixed solvent, stir and dissolve at 50-60°C, add the oxidized fiber, stir and mix, then drop glacial acetic acid, continue to react for 12-24 hours, cool, filter, wash alternately with deionized water and anhydrous ethanol, and dry to obtain the perspiration antibacterial functional fiber; use glacial acetic acid as a catalyst to combine the amino group in the modified antibacterial agent with the aldehyde group on the surface of cellulose to obtain the perspiration antibacterial functional fiber grafted with the modified antibacterial agent.
[0010] Furthermore, the usage ratio of the sodium hydroxide solution and the Lylecell fiber is 450 mL: 10-15 g; and the concentration of the sodium hydroxide solution is 3-5 wt %.
[0011] Furthermore, the dosage ratio of the sodium periodate solution to the activated fiber is 500 mL:10-15 g; and the concentration of the sodium periodate solution is 1.49-7.44 mg / mL.
[0012] Furthermore, the dosage ratio of the mixed solvent, modified antibacterial agent, oxidized fiber and glacial acetic acid is 500mL:30-60g:10-15g:0.02-0.1mL; the mixed solvent is composed of N,N-dimethylformamide and methanol in a volume ratio of 1:1.
[0013] Furthermore, the modified antibacterial agent is prepared by the following steps:
[0014] A1. Add 3,5-dibromosalicylaldehyde to anhydrous ethanol, stir and mix, then add an anhydrous ethanol solution of N(4)-substituted thiosemicarbazide intermediate, stir and mix, then dropwise add 98wt% concentrated sulfuric acid, and reflux at 78°C for 3-4h to obtain a thiosemicarbazide derivative; condense 3,5-dibromosalicylaldehyde with the N(4)-substituted thiosemicarbazide intermediate using concentrated sulfuric acid as a catalyst to obtain a thiosemicarbazide derivative containing a 3,5-dibromosalicylaldehyde structure;
[0015] A2. Add a thiosemicarbazone derivative to methanol, stir and dissolve at 50-60°C, then drop a methanol solution of anhydrous copper bromide, control the dropping time to 30-50min, and reflux the reaction at 65°C for 5-6h. After cooling, filter, wash and dry to obtain a modified antibacterial agent; using methanol as a solvent, the nitrogen atom and sulfur atom in the thiosemicarbazone derivative provide electron pairs to coordinate with copper ions to obtain a modified antibacterial agent with the thiosemicarbazone derivative as a ligand and copper as a central ion.
[0016] Furthermore, the dosage ratio of the anhydrous ethanol, 3,5-dibromosalicylaldehyde, the anhydrous ethanol solution of the N(4)-substituted thiosemicarbazide intermediate and concentrated sulfuric acid is 50mL:3-7g:10mL:0.02-0.08mL; the concentration of the anhydrous ethanol solution of the N(4)-substituted thiosemicarbazide intermediate is 0.15-0.4g / mL.
[0017] Furthermore, the usage ratio of the methanol, the thiosemicarbazone derivative and the methanol solution of anhydrous copper bromide is 90 mL: 3-7 g: 20 mL; and the concentration of the methanol solution of anhydrous copper bromide is 0.12-0.23 g / mL.
[0018] Further, the N(4)-substituted thiosemicarbazide intermediate is prepared by the following steps:
[0019] Add ethanolamine and concentrated ammonia water to anhydrous ethanol, stir and mix, add carbon disulfide dropwise at 25-30°C, control the dropping time to be 10-15min, stir and react for 30-50min, let stand at room temperature for 1h, then add sodium chloroacetate, continue stirring for 20-30min, then add hydrazine hydrate, react for 1-1.5h, heat and concentrate to 1 / 2 of the original volume, precipitate crystals, filter, wash and dry to obtain N(4)-substituted thiosemicarbazide intermediate; under alkaline conditions, ethanolamine and carbon disulfide undergo condensation reaction, and use sodium chloroacetate as a nucleophilic reagent to obtain N(4)-substituted thiosemicarbazide salt, and then use hydrazine hydrate as a nucleophilic reagent to carry out substitution reaction to obtain N(4)-substituted thiosemicarbazide intermediate containing hydroxyethyl group.
[0020] Furthermore, the usage ratio of anhydrous ethanol, ethanolamine, concentrated ammonia water, carbon disulfide, sodium chloroacetate and hydrazine hydrate is 50mL: 6-11g: 18mL: 7-10mL: 11-17g: 10-14mL.
[0021] A perspiration-wicking and antibacterial functional fiber is prepared by the above preparation method.
[0022] Beneficial effects of the present invention:
[0023] The surface of the modified antimicrobial agent of the present invention contains amino groups. When mixed with oxidized fiber, the amino groups can form imine bonds with aldehyde groups on the surface of the oxidized fiber, thereby firmly grafting the modified antimicrobial agent on the surface of the oxidized fiber, thereby enhancing the interaction between the modified antimicrobial agent and the fiber molecules. The molecular structure of the modified antimicrobial agent also contains thiosemicarbazone derivatives and copper ions complexed therewith. On the one hand, the active oxygen ions on the thiosemicarbazone derivatives can effectively hinder the reproduction of microorganisms such as bacteria through redox reactions. At the same time, the bromine atoms on the thiosemicarbazone derivatives can also enhance the inhibitory activity of bacteria, thereby improving the antimicrobial performance of the functional fiber. On the other hand, when the metal copper ions contact the microorganisms, they can destroy the protein structure of the microorganisms, causing the bacterial microorganisms to die, thereby providing good functional sterilization performance. The antimicrobial performance of the functional fiber is enhanced through the synergistic effect of the two. In addition, the copper ions can also play a catalytic role, catalyzing the oxygen-containing groups in the thiosemicarbazone derivatives to generate more active hydroxyl free radicals and active oxygen ions, thereby accelerating the sterilization efficiency of the modified antimicrobial agent. Under the synergistic effect of the two, the antimicrobial performance of the functional fiber is further enhanced.
[0024] The present invention uses Lylece fiber as a base material and oxidizes the surface of the Lylece fiber by sodium periodate. On the one hand, it can provide chemical sites for the grafting of modified antibacterial agents, enhance the intermolecular interaction between the modified antibacterial agent and the functional fiber, and improve the antibacterial performance. On the other hand, it can increase the roughness of the surface of the functional fiber, increase the surface area of the functional fiber, and thus increase the adsorption and discharge of sweat by the functional fiber, further enhancing the perspiration performance of the functional fiber.
