Description

Technical Field

[0001] The invention relates to the technical field of socks, in particular to a pair of high-strength antibacterial and anti-odor socks. Background Art

[0002] As a necessity for daily wear, socks not only need to meet basic comfort and breathability, but also need to have certain antibacterial and anti-odor functions to prevent bacterial growth and odor on the feet. However, existing socks products have many deficiencies in terms of antibacterial and anti-odor effects, strength, breathability and comfort, which are specifically manifested in the following aspects:

[0003] (1) The antibacterial and deodorizing effects are not long-lasting: Many sock products use chemical antibacterial agents, which are easily ineffective after repeated washing, resulting in a decrease in the antibacterial and deodorizing effects.

[0004] (2) Insufficient strength: Traditional socks are prone to wear and tear when worn for long periods of time or during outdoor activities, especially in the toes and heels, which are prone to holes or damage.

[0005] (3) Poor breathability: Existing socks are often made of a single fiber material with poor breathability. Long-term wearing can easily lead to the inability to discharge foot sweat in time, increasing bacterial growth and the generation of odor.

[0006] (4) Limited comfort: The knitting density and pore structure of traditional socks are not designed reasonably, resulting in low comfort when worn. Especially in hot summer or when walking for a long time, the feet are prone to feeling stuffy and tired. Summary of the invention

[0007] The present invention provides a high-strength antibacterial and deodorizing socks, which not only improve the strength and durability of the socks, but also significantly enhance the antibacterial and deodorizing effects thereof, while ensuring good air permeability and comfort by adopting composite yarns and three-dimensional knitting technology.

[0008] The technical scheme adopted by the present invention is: a high-strength antibacterial and deodorizing socks, which are formed by blending cotton fiber, elastic fiber, nylon fiber, polyester fiber, and silver antibacterial fiber to form a composite yarn with antibacterial function, and then formed by three-dimensional knitting technology to obtain socks with microporous structures on the surface, and finally impregnated with a treatment agent to obtain finished socks.

[0009] The raw materials of the treatment agent include, by weight: 1-5 parts of nano silver ion solution, 5-10 parts of waterborne polyurethane emulsion, 3-8 parts of acrylic resin, 1-3 parts of silane coupling agent, 0.5-2 parts of UV protection agent, 0.1-0.5 parts of defoaming agent, 1-2 parts of softener and 70-80 parts of water.

[0010] As a further improvement of the present invention, the cotton fiber accounts for 40%-60% of the total weight, the elastic fiber accounts for 10%-15%, the nylon fiber accounts for 15%-20%, the polyester fiber accounts for 5%-15%, and the silver antibacterial fiber accounts for 10%-20%.

[0011] As a further improvement of the present invention, the weaving density of the three-dimensional weaving technology is 80-120 meshes per square centimeter, ensuring that the socks have good air permeability and comfort.

[0012] As a further improvement of the present invention, the solid-liquid ratio of the socks to the treatment agent is 1:(5-20), and an ultrasonic impregnation process is used to allow the treatment agent to evenly penetrate into the fiber structure of the socks, thereby enhancing the antibacterial and deodorizing effects.

[0013] As a further improvement of the present invention, the silane coupling agent is one or more combinations of γ-aminopropyltriethoxysilane, γ-methacryloxypropyltrimethoxysilane, N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane, and n-dodecyltrimethoxysilane.

[0014] As a further improvement of the present invention, the UV protection agent is one or more combinations of phenyl o-hydroxybenzoate, 2-(2'-hydroxy-5'-methylphenyl)benzotriazole, and 2,4-dihydroxybenzophenone.

[0015] As a further improvement of the present invention, the defoaming agent is one or more combinations of polydimethylsiloxane, polyether-modified polysiloxane, and ethylene glycol siloxane.

[0016] As a further improvement of the present invention, the softener is one or more combinations of fatty alcohol polyoxyethylene ether, fatty acid amide, and polyethylene glycol fatty acid ester.

[0017] As a further improvement of the present invention, the concentration of the nano silver ion solution is 10-50 ppm.

[0018] As a further improvement of the present invention, the temperature of the treatment agent impregnation process is controlled at 30-50° C. and the time is 20-60 minutes to ensure that the treatment agent fully penetrates.

[0019] Beneficial effects of the present invention: (1) Significantly enhanced antibacterial and deodorizing properties: The socks of the present invention are treated with silver-based antibacterial fibers and nano-silver ion solution, which can effectively inhibit bacterial growth and thus reduce the generation of odor.

[0020] (2) Excellent strength and durability: The present invention scientifically mixes cotton fiber, elastic fiber, nylon fiber and polyester fiber, and applies three-dimensional knitting technology to make the socks soft and comfortable while having better mechanical strength and wear resistance, making them particularly suitable for long-term wear and outdoor sports.

[0021] (3) Excellent breathability and comfort: The use of three-dimensional knitting technology not only improves the wear resistance of the socks, but also forms a unique micro-pore structure inside the socks, creating a good air circulation environment for the soles of the feet.

[0058] In order to verify the performance of the high-strength antibacterial and deodorizing socks in Examples 1-3, the following test items were conducted: antibacterial performance, deodorizing performance, wear resistance, air permeability, UV protection performance and comfort. The test results are as follows:

[0059]

[0060] Test method description

[0061] (1) Antibacterial performance: The ISO 20743 standard is used for testing, and the antibacterial effect is evaluated by measuring the growth of microorganisms on the surface of socks.

[0062] (2) Anti-odor performance: The ASTM E2126 standard was used for testing, and the changes in odor concentration of socks under simulated usage conditions were measured using a gas analyzer.

[0063] (3) Wear resistance: The AATCC 93 standard is used for testing. The wear tester is used to simulate the wear of socks during wearing and the wear cycle is recorded.

[0064] (4) Breathability: The ASTM E96 standard is used to test the breathability of socks by measuring their moisture permeability.

[0065] (5) Ultraviolet protection performance: The ISO 13758 standard is used for testing. The ultraviolet protection ability of the socks is measured using a UV transmittance tester to evaluate the UPF value.

[0066] (6) Comfort: The temperature and humidity sensors are used to measure the temperature changes of the feet while the device is being worn to assess the comfort level.

[0067] (7) Finished product appearance: Visual inspection to evaluate color uniformity and appearance consistency.

[0068] (8) Elasticity: The elastic recovery rate of the socks was measured using a tensile testing machine to evaluate their elastic properties.

[0069] (9) Dimensional stability: The dimensional stability of socks is evaluated by measuring the dimensional changes before and after washing.

[0070] (10) Washing stability: After 10 standard washes, the antibacterial properties of the socks were measured again to evaluate their washing stability.

[0071] It can be seen from the above test results that the high-strength antibacterial and anti-odor socks in Examples 1-3 all exhibit excellent antibacterial and anti-odor performance, wear resistance, air permeability and comfort. In particular, the enhanced treatment of the toes and heels significantly improves the wear resistance of these parts, making them suitable for long-term wear and outdoor sports. In addition, the impregnation process of the treatment agent effectively improves the antibacterial and anti-odor effect of the socks, and can still maintain a high antibacterial rate after multiple washings.
