Description

Technical Field

[0001] The present invention relates to the technical field essential for human life, and particularly relates to a micro-nano transparent mosquito-proof silk stocking and a preparation method thereof. Background Art

[0002] The development of the times and the growth of the national economy have promoted the transformation of people's consumption concepts. Knitted products with comfort and fashionability have become the pursuit of more and more consumer groups. Taking this opportunity, the silk stocking industry, as a fast-moving consumer good, has developed rapidly. From the perspective of the import and export market, China has become the world's largest silk stocking producer, with a large production scale and a relatively high export volume.

[0003] As is well known, insect bite dermatitis is a common disease in dermatology in summer, which can be caused by bites or stings of insects such as mosquitoes, mites, midges, fleas, bees, ants, etc., among which mosquito bites are the most common. It often shows papules, wheals, erythema, blisters, papulovesicles, etc. at the bitten area. A bitten mark can be seen in the center of the skin lesion, and there are varying degrees of stabbing pain, burning pain, and itching, which affect people's daily life and rest. In severe cases, scratching and breaking can lead to secondary infection. Most wearers of silk stockings are female groups, and the wearing season is mostly summer. They are rich in colors, various in types, comfortable and beautiful, and are deeply loved by everyone. In summer, the silk stockings commonly worn by women are mostly 15D, with an average fiber diameter of 74.80 μm and an inscribed circle diameter of the coil of 317 μm. The mouthpart diameter of the common Aedes albopictus is 25 μm, which can obviously penetrate through the silk stockings to bite the human skin and cause redness, swelling, stabbing pain, and itching.

[0004] Therefore, there is a need for a silk stocking that can prevent mosquito bites. Summary of the Invention

[0047] Embodiment 2

[0048] A micro-nano transparent mosquito-proof silk stocking and its preparation method, as Figure 1 shown, is specifically implemented according to the following steps:

[0049] Step 1: As Figure 2 shown, use a jacquard silk stocking machine to prepare a silk stocking body 1 made of 15D spandex fiber;

[0050] Step 2: As Figure 3 shown, use a micro-nano weaving machine to prepare a sock body made of ultra-fine denier nylon fiber 2, and perform a "one"-shaped interlaced weaving along the direction parallel to the coils in the silk stocking to form a "one"-shaped silk stocking structure; the density is 20 pieces / mm;

[0051] As Figure 4As shown, the superfine denier nylon fiber is interwoven again along the direction perpendicular to the coils inside the stockings, forming a "cross"-shaped stocking structure; the density is 20 strands / mm;

[0052] As Figure 5 shown, the superfine denier nylon fiber is interwoven again along +45° and -45°, making a "rice"-shaped stocking structure, and the density is 20 strands / mm.

[0053] Example 3

[0054] A micro-nano transparent mosquito-proof stocking and its preparation method, as Figure 1 shown, are specifically implemented according to the following steps:

[0055] Step 1: As Figure 2 shown, use a jacquard stocking machine to prepare a stocking body 1 of 15D spandex fiber;

[0056] Step 2: As Figure 3 shown, use a micro-nano weaving machine to prepare a sock body of superfine denier nylon fiber 2, and conduct a "one"-shaped interweaving along the direction parallel to the coils inside the stockings, making a "one"-shaped stocking structure; the density is 20 strands / mm;

[0057] As Figure 4 shown, the superfine denier nylon fiber is interwoven again along the direction perpendicular to the coils inside the stockings, forming a "cross"-shaped stocking structure; the density is 20 strands / mm;

[0058] As Figure 5 shown, the superfine denier nylon fiber is interwoven again along +45° and -45°, making a "rice"-shaped stocking structure, and the density is 20 strands / mm;

[0059] As Figure 6 shown, then inside the "rice"-shaped structure, around the intersection of the "rice" and within the stocking body fibers, conduct a "square"-shaped superfine denier nylon fiber interweaving;

[0060] As Figure 7 shown, then conduct a "one"-shaped interweaving parallel to the coil direction above the intersection of the "rice", and the density is 20 strands / mm;

[0061] As Figure 8 shown, then the superfine denier nylon fiber is interwoven again along the direction perpendicular to the coils inside the stockings between the vertical interweaving lines, and the density is 20 strands / mm.

[0062] Example 4

[0063] A micro-nano transparent mosquito-proof stocking and its preparation method, as Figure 1 shown, are specifically implemented according to the following steps:

[0064] Step 1: As Figure 2 shown, use a jacquard stocking machine to prepare a stocking body 1 of 15D spandex fiber;

[0065] Step 2: As Figure 9 shown, use a micro-nano knitting machine to prepare a sock body of superfine denier nylon fiber 2. After threading the yarn perpendicular to the yarn direction, the density of the micro-nano fibers in the +45° and -45° directions can be increased.

[0066] Examples 3 and 4 also include Step 3: Mix dimethyl sulfoxide solvent and m-cresol solvent in a volume ratio of 24:1 at room temperature to prepare a solution; place the mixed solution in a container at room temperature, and stretch and suspend the stocking knitted according to Step 2 above the container; heat the bottom of the container and gradually heat it to 210°C. During the evaporation of the mixed solution, the poor solvent with a boiling point of 189°C evaporates first, which plays a protective role for the knitting structure. Subsequently, the good solvent with a boiling point of 202°C evaporates, and the dissolved fiber components solidify and connect the stocking body 1 and the knitted fiber layer 2 after the heating ends.

[0067] The size of the internal coils of the micro-nano transparent mosquito-proof stockings prepared in Examples 3 and 4 is less than 20 μm. When mosquitoes suck blood, their broad and serrated upper jaws are used to cut the skin, while their narrow and barbed lower jaws are used to prevent the mouthparts from slipping and further piercing the skin. However, when the stocking coil size is less than 20 μm and the silk threads are knitted and interwoven in multiple layers, the stocking coil size is less than the minimum mouthpart diameter of mosquitoes, which is 25 μm, and it can effectively prevent the mosquito mouthparts from cutting the structure of the knitted stockings, thus avoiding mosquito bites.

[0068] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
