DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Embodiment 1 like Figures 1-2 as well as Figure 4 As shown, the present invention discloses a sock for preventing blistering on the sole of the foot, comprising: a sock body 100 and a sock bottom, wherein the sock bottom comprises a bottom upper layer 110, a traction layer 120 and a bottom lower layer 130 from top to bottom, wherein the traction layer 120 comprises a plurality of traction units, wherein one end of the traction unit is connected to the bottom upper layer 110, and the other end is connected to the bottom lower layer 130, so that the bottom upper layer 110 and the bottom lower layer 130 can move relative to each other. The bottom upper layer 110 can be woven from cotton, wool, nylon, polyester, bamboo fiber or Leica, the traction unit can be made of nylon fiber or MOLO yarn, and the bottom lower layer 130 is made of nylon, polyester, nylon or Leica dense weave. In this embodiment, the material of the bottom upper layer 110 is a soft, breathable polyester material, which is used to improve the comfort and air permeability of the foot, thereby reducing the temperature and humidity of the foot. The bottom layer 130 is made of breathable polyester material with relatively high friction, which is used to improve breathability, reduce foot temperature and humidity, and increase friction to prevent the socks and insoles from moving relative to each other. The traction layer 120 is used to prevent the upper and lower layers from moving relative to each other too much during walking.

[0028] In this embodiment, when running, there is a horizontal ground reaction force when the foot touches the ground. At this time, because the bottom layer 130 has a large friction force, it is relatively still with the insole; and the foot drives the bottom upper layer 110 to move due to inertia, so that the bottom layer 130 and the bottom upper layer 110 move relative to each other. This avoids the mutual movement between the socks and the sole of the foot, and avoids the separation of the epidermis and subcutaneous tissue due to shear force and friction to form blisters.

[0029] In this embodiment, when the foot is in a wet state for a long time, the moisture metabolism of the skin will be affected, resulting in thinning of the stratum corneum and damage to the skin barrier function. Such damaged skin is more susceptible to external stimuli and infection, thereby increasing the risk of blisters. The use of breathable materials in the bottom upper layer 110, the traction layer 120 and the bottom lower layer 130 can prevent the foot from getting wet.

[0030] The bottom upper layer 110 is made of polyester, and the bottom lower layer 130 is made of densely woven polyester material. The pulling unit is in the shape of a line, a sheet, a block or a column, and one end of the pulling unit is connected to the bottom upper layer 110, and the other end is connected to the bottom lower layer 130. In this embodiment, the pulling layer 120 is made of MOLO yarn.

[0031] In this embodiment, the bottom of the sock body 100 (including the bottom upper layer 110, the traction layer 120 and the bottom lower layer 130) has a thickness of 5 mm, and the thickness of the traction layer 120 is 2-4 mm. MOLO yarn has good air permeability. MOLO yarn is wear-resistant and applicable, and never pills. Because the structure is made of tens of thousands of polymer synthetic fiber yarns, it is warp-knitted by knitting. It is not only strong, able to withstand high-strength tension and tearing, but also smooth and comfortable.

[0032] Several layers of MOLO yarn are arranged between the bottom upper layer 110 and the bottom lower layer 130. The pulling layer 120 is formed by high-temperature shaping of MOLO yarn. Its cross section is arc-shaped, and the middle part of the arc bulges toward the direction corresponding to the toe or heel of the sock body 100. In this embodiment, when relative displacement occurs between the bottom upper layer 110 and the bottom lower layer 130, the arc-shaped MOLO yarn can extend in the direction of the force. When the external force is reduced and withdrawn, its structure returns to its original state, maintaining a certain elongation in the horizontal and vertical directions, and has a moderate adjustment function. Because the MOLO yarn is arranged in an arc-shaped sheet, agglomeration can be avoided.

[0033] In this embodiment, the bottom lower layer 130 and the sock body 100 are knitted together as one. In other embodiments, the bottom lower layer 130 and the sock body 100 are connected by brushing glue.

[0034] Embodiment 2 like Figure 3As shown, the difference between this embodiment and the first embodiment is that the pulling unit is composed of a plurality of pulling wires, the pulling wires are monofilament pulling wires, textile pulling wires or a combination of monofilament pulling wires and textile pulling wires, and the length of the pulling wires is 2-4 mm. In this embodiment, the pulling wires are polyester monofilaments.

[0035] The distribution density of the traction line at the bottom of the sock corresponding to the position from the first metatarsal to the fifth metatarsal of the human body is greater than that at other positions of the bottom of the sock. In this embodiment, the horizontal shear force is distributed throughout the sole of the foot, but the force is greatest under the first to fifth metatarsal bones. Therefore, the middle traction layer 120 has a higher distribution density under the first to fifth metatarsal bones and a relatively long length of 3 mm, so as to ensure that when a large horizontal shear force is received at this location, it is buffered by a large deformation, thereby avoiding separation of the plantar epidermis and subcutaneous tissue and reducing the probability of blisters.

[0036] Embodiment 3 like Figures 5 to 8 The difference between this embodiment and the first embodiment is that the pulling unit includes an upper surface layer 121, a lower surface layer 122, and a plurality of pulling wires 123 connected to the upper surface layer 121 and the lower surface layer 122. The pulling wire 123 is a monofilament pulling wire, a textile pulling wire, or a combination of a monofilament pulling wire and a textile pulling wire. A filler is arranged in the pulling unit. The filler plays a certain supporting and warming role, and the filler can be a desiccant, a deodorant, or a supercritical foaming material. In this embodiment, the cross-section of the pulling unit is a square or a rhombus with equal sides.

[0037] The upper surface layer 121 is connected to the bottom upper layer 110, and the lower surface layer 122 is connected to the bottom lower layer 130. The upper surface layer 121 and the lower surface layer 122 are hollow structures. The hollow design can reduce the weight of the pulling unit to save materials used in production, thereby reducing the weight of the sock body 100. In other embodiments, the upper surface layer 121 of each pulling unit is integrally formed, and the lower surface layer 122 of each pulling unit is integrally formed.

[0038] Embodiment 4 This embodiment discloses a method for making socks, comprising the following steps: S1. The sock body and the bottom upper layer of the sock are integrally formed.

[0039] S2, manufacturing the bottom lower layer and the pulling unit. The pulling unit is any one of the structures in Embodiments 1 to 3.

[0040] S3. Fix the upper end of the pulling unit to the upper layer of the bottom, and fix the lower end of the pulling unit to the lower layer of the bottom.

[0041] S4. Sew or glue the edge of the bottom lower layer and the edge of the bottom upper layer together.

[0042] Alternatively, include the following steps: S1. The sock body and the bottom upper layer of the sock are integrally formed.

[0043] S2, manufacturing the bottom lower layer and the pulling unit. The pulling unit is any one of the structures in Embodiments 1 to 3.

[0044] S3, fix the upper end of the traction unit to the upper layer of the bottom, and fix the lower end of the traction unit to the lower layer of the bottom. Stuff the traction layer 120 with fillers. The fillers are soft and skin-friendly materials, such as antibacterial cotton, deodorant fiber, elastic fiber, etc. Stuffing the fillers not only enables the socks of the present application to prevent blistering on the soles of the feet, but also has antibacterial, deodorant, increase elasticity, or support functions. A small amount of fillers can be added, and the filling rate does not exceed 50% to avoid affecting the traction adjustment function of the traction unit.

[0045] S4. Sew or glue the edge of the bottom lower layer and the edge of the bottom upper layer together.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
