Description

Technical Field

[0001] This invention relates to the field of daily necessities, and in particular to an antibacterial sock that absorbs sweat and deodorizes, and a method for preparing the same. Background Technology

[0002] Socks are a necessity in people's lives. Although small, their performance directly affects foot comfort and human health. The average person wears socks for more than 12 hours a day. If socks have antibacterial properties, they can undoubtedly create a health barrier for the body. Today, socks with various health functions such as antibacterial, odor-resistant, moisture-wicking, breathable, and anti-static properties are constantly emerging.

[0003] CN202120468393.4: This utility model discloses an odor-deterrent and antibacterial sock, belonging to the field of clothing and accessories technology. An odor-deterrent and antibacterial sock includes a sock cuff, a sock leg fixedly connected to the bottom end of the cuff, a sock heel fixedly connected to the bottom end of the sock leg, the sock heel including an antibacterial layer, a first abrasion-resistant layer on the outer surface of the antibacterial layer, a sock sole fixedly connected to one side of the sock heel, the sock sole including a first odor-deterrent and antibacterial layer, a water-absorbing layer on the outer surface of the first odor-deterrent and antibacterial layer, and a sock toe fixedly connected to one end of the sock sole, the sock toe including a second odor-deterrent and antibacterial layer. In this utility model, since the soles of the feet are most prone to sweating, the first odor-deterrent and antibacterial layer of the sock sole is woven from silver thread, activated carbon fiber, and cotton thread. Different weaving materials are used according to corresponding parts, which not only saves materials but also maximizes performance, preventing bacterial growth and providing odor-deterrent and sweat-absorbing functions, making it more comfortable to wear.

[0004] CN202020360344.4: This utility model discloses a deodorizing and antibacterial sock, comprising a sock body, a first elastic band fixedly connected to the upper end of the sock body, and a first medicated application opening at the rear end of the sock body. A first medicated band is detachably connected to the outer rear end of the first medicated application opening, and foot crack ointment is fixedly connected inside the first medicated band. A second medicated application opening is fixedly connected to the front end of the sock body, and a second medicated band is detachably connected to the outer side of the second medicated application opening. Onychomycosis ointment is fixedly connected to the inner side of the second medicated band, and a second elastic band is fixedly connected to the middle end of the sock body. This deodorizing and antibacterial sock effectively reduces the occurrence of onychomycosis, athlete's foot, and foot cracks, increases the overall deodorizing effect, enhances the overall treatment effect, prevents ordinary socks from wiping off the ointment, and improves the overall treatment effect.

[0005] CN202022730250.4: This utility model discloses a sweat-absorbing and antibacterial sock, including a sock body one, a sock body two, and a sock leg. The sock body two is overlaid on the sock body one. The sock body one is provided with a connecting component for connecting the sock body one and the sock body two. The sock body one and the sock body two are symmetrically provided with through holes one and two, respectively. The positions of through holes one and two are the same. A connecting ring is fixed to the lower end of the sock leg. The connecting ring passes through through holes one and two. A button is fixed to the lower end of the sock leg. One end of the connecting ring that passes through through holes one and two is overlaid on the button. A sweat-absorbing layer and an antibacterial film layer are fixed to the inner side of the sock body one. It has the advantage of being able to adjust the length and thickness of the sock at any time.

[0006] The antibacterial socks mentioned above, along with existing technologies, exhibit varying antibacterial effects against four types of fungi: silver ion-treated antibacterial socks show the best antibacterial effect against Trichophyton rubrum, and also have some inhibitory effect on the other three types of fungi; bamboo pulp fiber antibacterial socks show good inhibitory effects against Trichophyton mentagrophytes and Epidermophyton floccosum, but have no inhibitory effect on Candida albicans; bamboo charcoal fiber antibacterial socks also do not inhibit Candida albicans, but have a good inhibitory effect on Trichophyton mentagrophytes. Summary of the Invention

[0007] The technical objective of this invention is to prepare an antibacterial sock that has a high-efficiency antibacterial effect against four types of fungi. Based on this, this invention discloses an antibacterial sock that absorbs sweat and deodorizes, and its preparation method, which belongs to the field of daily necessities.

[0008] In a first aspect, embodiments of the present invention provide an antibacterial sock that absorbs sweat and deodorizes, and a method for preparing the same, the steps of which are as follows:

[0009] According to the mass fraction, soak 15-24 parts of cotton socks in a finishing solution containing 15-25 parts of Chinese herbal extract, 3-6 parts of citric acid, 1-3 parts of sodium hypophosphite, and 0.5-2 parts of coconut oil softener, and perform two soakings and two squeezings; after soaking and squeezing, dry the cotton socks, bake them at high temperature, and then wash them thoroughly with deionized water at 30-40℃, and air dry them at room temperature to obtain sweat-absorbing and deodorizing antibacterial socks.

[0010] Specifically, preferably, the socks are commercially available 100% pure cotton socks.

[0011] Specifically, preferably, the rolling yield is 80-90%.

[0012] Specifically, preferably, the drying temperature is 65-80℃ and the time is 3-7 minutes.

[0013] Specifically, preferably, the baking temperature is 125-140℃ and the time is 2-5 minutes.

[0014] Secondly, embodiments of the present invention provide a method for preparing a water extract of traditional Chinese medicine as follows:

[0015] According to the mass fraction, take 250-300 parts of Chinese medicine and let it air dry naturally in a cool place. After crushing, add 900-1000 parts of deionized water and soak at room temperature for 20-24 hours. Boil for 1-3 hours and filter. Add 400-500 parts of deionized water to the residue and continue to boil for 20-40 minutes. Filter and add deionized water to repeat the boiling once. Combine the three decoctions, filter and concentrate to obtain the Chinese medicine water extract.

[0016] Specifically, as a preferred option, the Chinese herb is clove or houttuynia cordata.

[0017] Specifically, preferably, the filter uses a 6-layer gauze filter.

[0018] Thirdly, embodiments of the present invention provide a method for preparing a coconut oil softener as follows:

[0019] S1: According to the mass fractions, in a dry reactor, add 40-60 parts of N-cocoyl-1,3-propylenediamine (61791-63-7), 2-6 parts of myristoyl chloride, 6-10 parts of tetramethylguanidine, and 200-300 parts of DMF. Mix thoroughly under nitrogen protection, and maintain the temperature at 80-90℃ with stirring for 1-4 hours.

[0020] S2: Add 1.5-5 parts of acryloyloxysilane, keep warm at 80-90℃ and stir for 0.5-2.5h. After completion, remove DMF by vacuum distillation and purify to obtain coconut oil softener.

[0021] Specifically, preferably, the acryloyloxysilane is selected from acryloyloxymethyltrimethoxysilane (CAS No.: 21134-38-3), methacryloyloxypropyltriethoxysilane (CAS No.: 21142-29-0), and (acryloyloxymethyl)dimethylmethoxysilane (CAS No.: 130771-16-3).

[0022] The core technology of this invention lies in:

[0023] The N-coco-1,3-propylene diamine and myristoyl chloride first react to form an amide, and the excess N-coco-1,3-propylene diamine continues to react with acryloyloxysilane to form a softener.

[0024] Compared with commercially available products, antibacterial and deodorizing socks made with traditional Chinese medicine as antibacterial and deodorizing agents have a more obvious antibacterial effect and a broader spectrum of antifungal activity; in particular, clove antibacterial socks have an antibacterial rate of over 90% against four types of fungi, and are widely available with relatively low production costs, making them more effective for foot care and disease prevention.
