Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of textiles, in particular to a copper alloy sock and a preparation method thereof. BACKGROUND

[0002] In daily life, people's feet are prone to sweating, and a humid environment provides favorable conditions for the breeding of bacteria, fungi and other microorganisms. The massive reproduction of these microorganisms not only produces odor, leading to the problem of foot odor, but also can cause dermatophytosis and other skin diseases, causing trouble to people's life. The effect of traditional socks in antibacterial and deodorization is often unsatisfactory, and their limited antibacterial performance decreases rapidly after being washed for several times.

[0003] At present, although some socks claiming to have antibacterial function appear on the market, most of them have problems such as unstable antibacterial components, non-durable antibacterial effect or potential harm to human body. For example, some antibacterial socks use chemically synthesized antibacterial agents, which may gradually release harmful substances during use, posing a threat to human health. At the same time, the socks made of some natural antibacterial fibers have relatively weak antibacterial effect, which cannot meet people's demand for high-efficiency antibacterial socks. Therefore, it is of important practical significance to develop a safe, efficient and durable antibacterial sock.

[0004] In recent years, some manufacturers have developed copper fiber socks by blending copper fibers into the sock fabric to enhance the functionality.

[0005] For example, patent document CN113089116A discloses a copper-silver series sterilization and deodorization artificial silk thread and its manufacturing method, which mainly includes: forming a copper series sterilizing agent from one or more combinations of elemental copper, copper oxide, cuprous oxide, copper salt nano powder or microparticles, incorporating the copper series sterilizing agent in a weight percentage of 1.8%-40% into a weight percentage of 93%-40% of polymer or polyester or polypropylene or acrylic or polyamide or nylon or spandex nano powder or master batch, adding 5%-10% of a compatibilizer, 0.1%-6% of a dispersant, and 0.1%-4% of an antioxidant, the sum of the compositions of each raw material being 100%, and placing the mixture into a high-speed mixer for 2-10 minutes, and then loading the mixture into a melt screw extruder, with a processing temperature of 160°C-320°C and a screw rotation speed of 180-800 rpm, to form a melt of the copper series sterilization polymer, copper series sterilization polyester, or copper series sterilization polypropylene, or copper series sterilization acrylic, or copper series sterilization polyamide, or copper series sterilization nylon, or copper series sterilization spandex, which are highly compatible, mutually adhered, and uniformly dispersed. By using the mixing, dispersing, and compatibilizing technology and / or the polymerization, esterification, and polycondensation technology of the present application, the effective copper and silver loading of the chemical fiber raw material can be realized to produce silk threads, and the threads can be blended or core-spun with cotton threads, silk threads, and wool threads to produce sterilization and deodorization chemical fiber fabrics, sterilization and deodorization blended cotton fabrics, and various copper and silver series sterilization and deodorization socks, which have the beneficial effect of sterilization and deodorization to protect human health.

[0006] In addition, patent document CN117418356A discloses a strong sterilization and deodorization copper alloy braided material and its preparation method, which mainly includes: using copper alloy to form copper-containing antibacterial silk, forming a strong sterilization and deodorization copper alloy functional material for human feet, to reduce the harm to the human body caused by existing silver-containing antibacterial fibers; and using the high toughness of copper alloy to solve the problems of low production efficiency, high cost, inability to achieve mass production, high braiding cost, poor color stability, poor quality, and unstable performance caused by silver fibers or silver particles as the main material in the prior art.

[0007] However, the above-mentioned solutions still have deficiencies in terms of durability and comfort in actual use: poor air permeability, which can cause skin discomfort, easy sweating, and bacterial growth during wearing; poor durability, such as oxidation of copper in the air, which can cause discoloration of the fiber surface, affecting the appearance and service life. SUMMARY

[0008] Therefore, the embodiments of the present application provide a copper alloy sock and a preparation method thereof.

[0009] To achieve the above-mentioned purpose, the embodiments of the present application provide the following technical solutions:

[0010] According to a first aspect of the embodiments of the present application, the present application provides a copper alloy sock, comprising a fabric mixed by copper alloy fibers and combed cotton, wherein the copper alloy fibers are fibers drawn from an alloy of copper, zinc, nickel and silver.

[0011] In some preferred embodiments, the mass percentage of each metal in the copper alloy fibers is: copper 60%-80%, zinc 5%-15%, nickel 5%-10%, and silver 1%-5%.

[0012] In some preferred embodiments, the mass percentage of the combed cotton in the fabric is 70%-85%.

[0013] In some preferred embodiments, the combed cotton is Xinjiang Jingao combed cotton.

[0014] According to a second aspect of the embodiments of the present application, the present application provides a preparation method of the copper alloy sock as described in any one of the above, comprising the following steps:

[0015] (1) melting and alloying copper, zinc, nickel and silver in proportion to obtain a copper alloy ingot, and then drawing the copper alloy ingot to form copper alloy fibers;

[0016] (2) using a splicing and integrating device, mixing the copper alloy fibers and combed cotton slivers by a combed tight Siro spinning yarn high-density 240 bonding strand blending technology to obtain blended yarn;

[0017] (3) knitting the blended yarn into a sock gray fabric by a knitting process;

[0018] (4) cutting, sewing and setting the sock gray fabric to obtain finished copper alloy socks.

[0019] In some preferred embodiments, in step (1), the temperature of the melting and alloying process is 1100-1200℃, and the time is 2-3 hours.

[0020] In some preferred embodiments, in step (1), the drawing process adopts a continuous drawing process, and the drawing speed is 5-10 m / min.

[0021] The present application has at least the following advantages:

[0022] (1) The present application provides a copper alloy sock, which comprises a fabric made of copper alloy fibers and combed cotton. The copper alloy fibers are drawn from an alloy of copper, zinc, nickel, and silver. Copper serves as the base material, providing good electrical conductivity and thermal conductivity while ensuring the basic mechanical properties of the alloy. The addition of zinc improves the strength and hardness of the alloy, inhibits the formation of copper oxides, and enhances the mechanical properties and corrosion resistance of the alloy. The addition of nickel enhances the tensile strength and hardness of the alloy, further improving its corrosion resistance. The addition of silver further enhances the corrosion resistance of the alloy, while also improving its antibacterial properties and corrosion resistance, resulting in better electrical conductivity and a more attractive appearance. The combed cotton fibers have good air permeability, and when combined with copper alloy fibers, the fabric not only has good air permeability and comfort, but also significantly improves antibacterial and deodorizing effects and durability.

[0023] (2) Stronger antibacterial and antiviral performance: Copper itself has antibacterial properties, and when combined with metals such as zinc and silver to form copper alloy fibers, it can further enhance the sterilization effect and inhibit more types of bacteria, fungi, and viruses, providing more comprehensive protection for the feet and effectively reducing foot odor, infection, and other problems caused by bacterial growth.

[0024] (3) More durable: Pure copper fibers are prone to oxidation and discoloration, while copper alloy fibers have better stability and are resistant to washing. Tests have shown that the copper alloy antibacterial functional socks of the present application can withstand more than 100 machine washes while maintaining more than 90% of their antibacterial rate, allowing them to maintain their antibacterial effect for a long time and extending the service life of the socks.

[0025] (4) Better comfort: The copper alloy fibers used in the present application are softer and more comfortable to wear, making them suitable for long-term wear. Some copper alloys, such as copper-nickel alloys, have better thermal conductivity, which can regulate foot temperature and reduce the feeling of stuffiness, improving the comfort of wearing.

[0026] (5) Additional functions: The copper alloy has stronger electrical conductivity, making the socks have anti-static properties and reducing the accumulation of static electricity, providing a more comfortable experience for the wearer.

[0027] (6) Wide range of applications: Suitable for athletes / outdoor enthusiasts, reducing bacterial growth caused by foot sweat, preventing blisters and odors; suitable for diabetics, reducing the risk of foot infections; for those with low immunity, preventing fungal infections; for those who wear shoes / boots for a long time, inhibiting foot odor and keeping feet dry, meeting the high demands of different groups for foot health.
