Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to an antibacterial labor protection shoe fabric and a preparation method thereof. Background Art

[0002] As consumers' requirements for footwear comfort, functionality and hygiene continue to increase, the market demand for antibacterial shoe fabrics is also increasing. Antibacterial modification of shoe fabrics can inhibit the growth of bacteria in shoe fabrics and reduce odor in shoes. The main method for preparing antibacterial shoe fabrics in the prior art is to use antibacterial agents to treat the fabrics. Although this method can also achieve good results, due to the poor compatibility of antibacterial agents with shoe fabrics, the antibacterial agents are prone to migration during use and daily washing, so the antibacterial effect cannot take effect for a long time. In addition, if the antibacterial agent added to the shoe fabric migrates and contacts the skin on the surface of the human body, it may also cause irritation or even allergic reactions. Based on this, the present invention provides an antibacterial labor protection shoe fabric and a preparation method thereof, which are used to solve the problems existing in the above-mentioned background technology. Summary of the invention

[0005] Furthermore, the upper material is one of nylon cloth, microfiber leather base cloth and canvas.

[0006] Furthermore, the leveling agent is BKY-333.

[0007] Furthermore, the alginate cross-linking agent is one of zinc chloride, barium chloride and calcium chloride.

[0008] Furthermore, in the third step, the heat drying and curing conditions are 85-90° C. for 2-3 min, and then 110-115° C. for 1-2 min.

[0009] Furthermore, the antibacterial modified polyurethane emulsion is prepared by the following steps: Step 1, m-hydroxybenzaldehyde, aniline, acetol, proline and dimethyl sulfoxide were mixed in a three-necked flask, magnetic stirring was started, and the mixture was reacted for 2 hours under temperature conditions. After the reaction was completed, a saturated ammonium chloride solution was added to the three-necked flask and stirring was continued for 5-10 minutes, followed by extraction with ethyl acetate, the organic layer was rotary evaporated to remove the solvent, and then silica gel column chromatography was performed to obtain intermediate 1; Step 2, intermediate 1, trichloroisocyanuric acid and toluene are mixed in a three-necked flask, a condenser and a thermometer are installed, magnetic stirring is turned on, and the mixture is reacted at room temperature for 12 hours. After the reaction is completed, the solvent is removed by rotary evaporation, and then intermediate 2 is obtained by silica gel column chromatography; Step 3, polytetramethylene ether glycol and 4,4'-diphenylmethane diisocyanate are mixed in a three-necked flask, a condenser and a thermometer are installed, magnetic stirring is turned on, the system temperature is raised to 80°C under nitrogen protection, and the reaction is carried out at 80°C for 1-1.5h, then the homemade mixed solution is added to the three-necked flask, and the reaction is continued at 80°C for 4-6h, then the system temperature is lowered to 40°C, and deionized water is added for emulsification to obtain the antibacterial modified polyurethane emulsion.

[0010] Furthermore, the amount ratio of m-hydroxybenzaldehyde, aniline, acetol, proline and dimethyl sulfoxide used in step 1 is 0.1 mol: 0.1-0.11 mol: 0.1-0.13 mol: 0.03 mol: 80-100 mL.

[0011] Furthermore, the usage ratio of the intermediate 1, trichloroisocyanuric acid and toluene used in step 2 is 0.08 mol: 0.08-0.1 mol: 80-100 mL.

[0012] Furthermore, the homemade mixed solution in step 3 is prepared from 0.02 mol of intermediate 2, 0.03 mol of triethylamine, 0.015 mol of N,N-dimethylethanolamine, 0.005 mol of 2-methylpentanediamine and 60 g of N,N-dimethylformamide.

The antibacterial labor protection shoe fabric of the invention has an antibacterial modified polyurethane with good antibacterial effect, and thus has good antibacterial ability.

[0015] The invention uses m-hydroxybenzaldehyde, aniline and acetol as raw materials, and obtains intermediate 1 by Mannich reaction between aldehyde group of m-hydroxybenzaldehyde and amino group of aniline and carbonyl group of acetol. Then, intermediate 2 is obtained by oxidation-reduction reaction between imino group of intermediate 1 and oxidant trichloroisocyanuric acid using intermediate 1 as raw material. Finally, polytetramethylene ether glycol and 4,4'-diphenylmethane diisocyanate are polymerized under the condition of a composite catalyst system of triethylamine, N,N-dimethylethanolamine and 2-methylpentanediamine and intermediate 2 as a chain extender to obtain an antibacterial modified polyurethane emulsion. The antibacterial modified polyurethane emulsion has a halamine structure, and the halamine has a strong broad-spectrum antibacterial effect. When in contact with microorganisms, the halogen atoms in the halamine structure can penetrate the cell wall of the microorganism, and then react with proteins in the cell to destroy the physiological structure and function of the microorganism, thereby achieving the purpose of antibacterial. The antibacterial effect can be circulated and effective, so the antibacterial effect of the antibacterial modified polyurethane emulsion also has good regeneration.

[0016] The preparation method of the antibacterial labor protection shoe fabric of the invention is simple and is suitable for a variety of different fabrics. The prepared antibacterial labor protection shoe fabric has good broad-spectrum antibacterial properties, has no irritation to the human body, and is safe and reliable. DETAILED DESCRIPTION
