Description

Technical Field

[0001] This application relates to the technical field of footwear products, and in particular to an antibacterial footwear material for women's shoes, a method for preparing the same, and women's shoes. Background Technology

[0002] As living standards continue to improve, people's demands for shoes are also increasing. In the current women's shoe market, not only are aesthetics and fashion a priority, but the requirements for antibacterial and deodorizing properties also greatly influence consumers' choices.

[0003] Traditional women's shoes, due to the high density of sweat glands on the feet, tend to produce large amounts of sweat during wear. Sweat contains water, salts, fats, and proteins, providing an ideal environment for bacterial growth. Bacteria proliferate in sweat, decomposing organic matter and producing substances with a distinctive odor, leading to foot odor. This significantly reduces comfort and is detrimental to health. Current technology involves coating fabrics with antibacterial agents to create antibacterial materials. However, the antibacterial properties of these fabrics decrease considerably after washing, making them unsuitable for long-term use. Summary of the Invention

[0004] To improve the antibacterial properties and washability of women's shoes, this application provides an antibacterial shoe material for women's shoes, its preparation method, and the women's shoes themselves.

[0005] In a first aspect, this application provides an antibacterial shoe material for women's shoes, employing the following technical solution: An antibacterial shoe material for women's shoes comprises the following raw materials in weight percentage: 30-50% micro-pitted antibacterial viscose fiber, with the remainder being nylon fiber and ramie fiber; the micro-pitted antibacterial viscose fiber is obtained by adding coated antibacterial zeolite to viscose spinning solution, mixing, and then spinning and alkali treatment. The coated antibacterial zeolite is prepared by adsorbing an antibacterial agent solution onto zeolite powder, drying it, coating its surface with a coating solution containing sodium bicarbonate, and then drying it at 130-150℃.

[0006] By adopting the above technical solution, this application utilizes the porosity of zeolite to adsorb a large amount of antibacterial agents. Then, a coating liquid containing sodium bicarbonate is coated onto its surface. The coating liquid forms a coating structure on the zeolite surface. The sodium bicarbonate then decomposes under high-temperature drying to form gas, creating a porous coating structure that allows the antibacterial agents in the zeolite to exert their antibacterial effect. Furthermore, both the coating structure and the porous structure of the zeolite powder contribute to water resistance, significantly extending the antibacterial and water-resistant properties of the antibacterial shoe material. Alkali treatment creates a micro-pit structure on the surface of the viscose fiber, increasing the specific surface area, improving the contact efficiency of the antibacterial agent, and enhancing antibacterial properties. Simultaneously, blending it with nylon and ramie fibers makes the shoe material breathable, which also contributes to the effectiveness of the antibacterial properties.

[0007] Preferably, the antibacterial agent in the antibacterial agent solution is one or both of polyhexamethylene monoguanidine hydrochloride and polyhexamethylene biguanidine hydrochloride.

[0008] By adopting the above technical solutions, this type of antibacterial agent has good antibacterial effect, is resistant to acids and alkalis, and is also resistant to high temperatures and water washing performance. It has low irritation to the human body and meets the ecological standards for textiles.

[0009] Preferably, the concentration of the antibacterial agent in the antibacterial agent solution is 9-11 wt%.

[0010] By adopting the above technical solution, zeolite powder can be soaked with antibacterial agent at this concentration to obtain antibacterial zeolite with excellent antibacterial properties.

[0011] Preferably, the coating solution comprises the following raw materials in weight percentages: 0.5-1.5% hydrophilic nano-silica, 0.05-0.5% glycerol, 6-10% sodium bicarbonate, 2-4% polyvinyl alcohol, and the balance being water.

[0012] By adopting the above technical solution, the hydrophilic nano-silica in the coating solution can act as an anti-caking agent, reducing the agglomeration of the coated antibacterial zeolite during the drying process and improving the dispersibility of the coated antibacterial zeolite in viscose fiber; glycerol can act as a plasticizer, improving the flexibility of the coating, and together with polyvinyl alcohol, it forms the main material of the coating, improving the compatibility between the zeolite and the viscose fiber system; sodium bicarbonate decomposes to form a porous structure in the coating, improving the antibacterial activity of the antibacterial agent; the various raw materials in the coating solution work synergistically to give the coated antibacterial zeolite excellent antibacterial properties while ensuring uniform dispersion in the viscose fiber system, reducing the surface tension with the viscose fiber system, and achieving good compatibility.

[0013] Preferably, the coated antibacterial zeolite is coated by spraying a coating liquid onto the surface of the antibacterial zeolite, and the mass ratio of the coating liquid to the antibacterial zeolite is 1:(0.8-2).

[0014] By adopting the above technical solution, the coating layer can be made less thick through spraying, and the phenomenon of excessive coating liquid clogging the zeolite pores and affecting the antibacterial performance can be avoided. At the same time, the amount of coating liquid used can also be reduced, reducing raw material waste and production costs.

[0015] Preferably, the particle size of the zeolite powder is ≤2μm.

[0016] By adopting the above technical solutions, ultrafine particle size can avoid clogging of the spinneret and ensure the quality of fiber forming; small-particle-size zeolite has a large specific surface area and a higher antibacterial agent loading capacity.

[0017] Preferably, the mass ratio of the coated antibacterial zeolite to the viscose spinning solution is (0.8-1.2):100.

[0018] Secondly, this application provides a method for preparing antibacterial shoe material fabric for women's shoes, which adopts the following technical solution: a method for preparing antibacterial shoe material fabric for women's shoes, comprising the following steps: blending and interweaving micro-pitted antibacterial viscose fiber, nylon fiber and ramie fiber to obtain antibacterial shoe material fabric for women's shoes.

[0019] By adopting the above technical solutions and through blending, nylon fiber can improve the tensile recovery of shoe material fabrics, ramie fiber has a higher moisture absorption rate than cotton, making it suitable for environments prone to sweating, and the addition of micro-grooved antibacterial viscose fiber blending makes the blended fabric very suitable for practical applications in shoe material fabrics.

[0020] Thirdly, this application provides a women's shoe, which adopts the following technical solution: A type of women's shoe, wherein the shoe material used in the women's shoe is an antibacterial shoe material.

[0021] By adopting the above technical solutions, women's shoes made from antibacterial shoe materials have long-lasting antibacterial properties, which can greatly improve the quality of antibacterial function in women's shoes.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application utilizes the porosity of zeolite, which can adsorb a large amount of antibacterial agents. Then, a coating liquid containing sodium bicarbonate is coated on its surface. The coating liquid can form a coating structure on the zeolite surface. Then, the sodium bicarbonate decomposes under high temperature drying to form gas, and then forms a porous coating structure, so that the antibacterial agents in the zeolite can exert their antibacterial effect. In addition, its coating structure can also provide water resistance, greatly extending the antibacterial and water-resistant properties of the antibacterial shoe material fabric. At the same time, blending it with nylon fiber and ramie fiber makes the shoe material fabric breathable, which is also conducive to the exertion of antibacterial properties.

[0023] 2. The antibacterial shoe material fabric prepared in this application has good antibacterial properties, and its antibacterial properties remain good even after 100 washes. Before washing, its antibacterial rate against Staphylococcus aureus can reach up to 99.3%, and after 100 washes, it can still reach 99.2%. Similarly, its antibacterial rate against Candida albicans can reach up to 99.1%, and after 100 washes, it can still reach 99.0%. It can be seen that the antibacterial shoe upper material prepared in this application has excellent antibacterial properties, and after 100 washes, there is almost no significant decrease, and its antibacterial and water-resistant properties are excellent.

[0042] Performance testing Detection methods / test methods Antibacterial shoe material fabrics for women's shoes were prepared according to the preparation methods of Examples 1-7 and Comparative Examples 1-3, and then tested according to the following testing methods. The test results are shown in Table 1.

[0043] Antibacterial properties: tested according to the test methods in GB / T 20944.2-2007 "Evaluation of antibacterial properties of textiles".

[0044] Table 1. Detection results of Examples 1-7 and Comparative Examples 1-3 As can be seen from Examples 1-7, Comparative Examples 1-3, and the test data in Table 1, the antibacterial shoe material fabric prepared in this application has good antibacterial properties, and its antibacterial properties remain good even after 100 washes. Before washing, its antibacterial rate against Staphylococcus aureus can reach up to 99.3%, and after 100 washes, it can still reach 99.2%. Similarly, its antibacterial rate against Candida albicans can reach up to 99.1%, and after 100 washes, it can still reach 99.0%. It can be seen that the antibacterial shoe upper material prepared in this application has excellent antibacterial properties, and after 100 washes, there is almost no significant decrease, and its antibacterial and water-resistant properties are excellent.

[0045] This application utilizes the porosity of zeolite to adsorb a large amount of antibacterial agents. A coating solution containing sodium bicarbonate is then applied to the zeolite surface, forming a coating structure. The sodium bicarbonate decomposes under high-temperature drying to form a gas, which in turn creates a porous coating structure, allowing the antibacterial agents in the zeolite to exert their antibacterial effect. Furthermore, the coating structure and the porous structure of the zeolite powder contribute to water resistance, significantly extending the antibacterial and water-resistant properties of the antibacterial shoe material. Alkali treatment creates a micro-pitted structure on the surface of the viscose fiber, increasing the specific surface area, improving the contact efficiency of the antibacterial agent, and enhancing antibacterial properties. Simultaneously, blending it with nylon and ramie fibers improves the breathability of the shoe material, further enhancing its antibacterial performance. Furthermore, the hydrophilic nano-silica in the coating solution acts as an anti-caking agent, reducing the agglomeration of the coated antibacterial zeolite during the drying process and improving its dispersibility in viscose fibers. Glycerin acts as a plasticizer, improving the flexibility of the coating and forming the main coating material with polyvinyl alcohol, thus improving the compatibility between the zeolite and the viscose fiber system. Sodium bicarbonate decomposes to create a porous structure in the coating, enhancing the antibacterial activity of the antibacterial agent. The synergistic effects of the various raw materials in the coating solution give the coated antibacterial zeolite excellent antibacterial properties while ensuring uniform dispersion in the viscose fiber system and reducing the surface tension with the viscose fiber system, resulting in good compatibility. The test data from Example 1 and Comparative Examples 1-2 show that the absence of hydrophilic nano-silica or polyvinyl alcohol affects the dispersion of the coated antibacterial zeolite, reducing its antibacterial activity. Combined with Comparative Example 3, without high-temperature drying, sodium bicarbonate cannot fully decompose, and its coating structure affects the antibacterial effect of the antibacterial agent.

[0046] Through Examples 1-3, the preferred concentration of added sodium bicarbonate is 6-10 wt%. Combined with Examples 4-5, a concentration of 0.5-1.5 wt% of hydrophilic nano-silica enables the coated antibacterial zeolite to be fully dispersed, resulting in a good anti-caking effect.

[0047] Through Examples 1 and 6-7, antibacterial shoe material fabrics prepared with a micro-pitted antibacterial viscose fiber content of 30-50% can all obtain good antibacterial effects.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
