Description
Technical Field
[0001] The utility model belongs to the technical field of webbings, and in particular relates to a shoulder strap with permanent anti-slip properties. Background Art
[0002] As living standards continue to improve, people's demands for comfort and functionality in textiles are also increasing. When women wear bras and underwear on a daily basis, the shoulder straps easily slip off, often requiring manual retraction. This affects the proper protection of the bras and underwear and significantly impacts comfort. Therefore, it is necessary to improve the anti-slip performance of shoulder straps to meet consumers' growing functional demands and enhance the market competitiveness of underwear products. Existing webbing products have uniform mechanical properties, such as stretch and rebound, which cannot meet special functional requirements.
[0003] The methods for improving the anti-slip performance in the prior art focus on adding anti-slip structures to the shoulder straps or changing the connection shape of the shoulder straps. The specific methods and their defects are as follows: 1. Adding an anti-slip coating of rubber or other materials to the skin-contacting surface of the shoulder straps significantly improves the anti-slip performance, but the rubber and coating have poor air permeability, which reduces the comfort of wearing, and increases the number of steps, which increases the cost and also reduces the production efficiency. Moreover, as the use time increases, the risk of the anti-slip coating falling off the shoulder straps increases; 2. Adding anti-slip buckles to the shoulder straps to buckle the two shoulder straps together; or when designing underwear, designing the shoulder straps into a cross shape or Y shape; the material of the anti-slip buckles and their raised settings will increase discomfort, and changing the shape of the shoulder straps when wearing makes the wearing process more inconvenient.
[0004] In view of this, there is an urgent need for a shoulder strap that improves its own anti-slip properties without affecting its performance. Utility Model Content
[0005] In view of this, the purpose of the present invention is to provide a shoulder strap with permanent anti-slip function, aiming to solve at least one technical problem in the background technology.
[0006] The utility model is achieved in this way:
[0007] The utility model provides a shoulder strap with permanent anti-slip function, which comprises a shoulder strap body, an adjusting buckle for adjusting the length of the shoulder strap body, and two sets of connecting buckles arranged at both ends of the shoulder strap body;
[0008] The shoulder strap body adopts an integrated webbing structure, and the warp yarn of the shoulder strap body includes spandex bare yarn and elastic yarn;
[0009] The longitudinal structure of the outer surface of the shoulder strap body is a grid shape consisting of a layer of spandex bare yarn and two layers of elastic yarn alternating up and down;
[0010] The shoulder strap body includes a non-anti-slip belt section and an anti-slip belt section located in the middle;
[0011] In the warp yarns of the non-slip belt segment, the spandex bare yarns are located in the middle layer, and the elastic yarns float on the surface;
[0012] In each group of unit grids on the outer belt surface of the anti-slip belt segment, at least one grid has bare spandex yarn floating on the surface.
[0013] Furthermore, the elastic yarn is spandex covered yarn or nylon yarn.
[0014] Furthermore, the unit grid in the anti-slip belt section is a 2X2 or 2X3 arrangement combination.
[0015] Furthermore, in each group of unit grids on the outer belt surface of the anti-slip belt segment, at least one grid is made of elastic yarn.
[0016] Furthermore, the webbing also includes weft yarns, which connect the warp yarns of the three-layer longitudinal structure into one.
[0017] Furthermore, the weft yarn is spandex covered yarn.
[0018] Furthermore, the length of the anti-slip belt segment accounts for 1 / 3 to 1 / 2 of the total length of the shoulder strap body.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. The utility model uses a layer of spandex bare yarn and two layers of elastic yarn as warp yarns, and forms shoulder straps with different mechanical properties and different anti-slip properties in different areas by alternating up and down, without changing the external shape of the shoulder straps or reducing the quality of use of the shoulder straps.
[0021] 2. The utility model integrates the anti-slip structure with the shoulder strap body, which is easy to wear and has no risk of the anti-slip coating falling off or the anti-slip buckle malfunctioning. It is permanent and the anti-slip effect will not disappear with long-term use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The orientation or positional relationship indicated by the terms "upper", "lower", "inside", "outside" etc. used herein is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this utility model.
[0029] like Figure 1 As shown, a shoulder strap with permanent anti-slip function includes a shoulder strap body, an adjustment buckle 4 for adjusting the length of the shoulder strap body, and two sets of connecting buckles 1 arranged at the head and tail ends of the shoulder strap body. The shoulder strap body includes a non-anti-slip belt section 2 and an anti-slip belt section 3 located in the middle.
[0030] In a specific implementation, the connecting buckle 1 is used to connect the shoulder strap to a bra, underwear, etc., and the adjusting buckle 4 is used to change the length of the shoulder strap body. The connecting buckle 1 and the adjusting buckle 4 can adopt the structure, composition and connection commonly used in this field, and will not be described in detail here.
[0031] The shoulder strap body adopts an integrated structure of webbing, which is made of warp yarn and weft yarn interwoven together, and the weft yarn connects the warp yarn into one.
[0032] The utility model improves the warp yarn. The warp yarn of the shoulder strap body includes a three-layer structure of spandex bare yarn and elastic yarn, specifically a layer of spandex bare yarn and two layers of elastic yarn. The longitudinal structure of the outer surface of the shoulder strap body is a grid shape composed of a layer of spandex bare yarn and two layers of elastic yarn alternating. The grid shape is achieved by exchanging the positions of a layer of spandex bare yarn and two layers of elastic yarn up and down. The outer surface refers to the skin-contacting surface and the back-skin surface.
[0033] Naked spandex yarns are directly used as warp yarns in the weaving process, resulting in a spandex-surfaced webbing with excellent anti-slip properties. The spandex-surfaced surface, similar to rubber, adheres strongly to the skin, effectively preventing slipping. Therefore, within each grid cell of the outer surface of the anti-slip tape segment 3, at least one grid cell is made of naked spandex yarn. This ensures that when the anti-slip tape segment 3 comes into contact with the skin, the contact surface contains the naked spandex yarns, further enhancing the anti-slip effect. In the non-anti-slip tape segment 2, the naked spandex yarns are located in the middle layer of the warp yarns, meaning they are not exposed.
[0034] like Figure 2 and Figure 3 As shown, the warp yarns of the shoulder strap body include spandex bare yarn 6, first elastic yarn 5 and second elastic yarn 7. In the non-anti-slip tape segment 2 and the anti-slip tape segment 3, different grids are formed on the outer tape surface by alternating the three layers of warp yarn in different ways.
[0035] Specifically, if Figure 2 As shown, in the non-anti-slip belt segment 2, the spandex bare yarn 6 is always in the middle layer and does not participate in the up and down position changes. The first elastic yarn 5 and the second elastic yarn 7 alternate in position up and down. Therefore, in the non-anti-slip belt segment 2, its outer belt surface is a grid formed by alternating first elastic yarns 5 and second elastic yarns 7, that is, the first elastic yarns 5 and the second elastic yarns 7 float on the surface, and the shoulder strap surface where the elastic yarns float on the surface has no anti-slip effect.
[0036] Specifically, in the anti-slip belt section 3, the first elastic yarn 5, the spandex bare yarn 6 and the second elastic yarn 7 are alternately positioned up and down. Figure 3One scenario is shown. For example, along the weaving direction, the spandex yarn 6 shifts from the middle layer to the top layer and then to the bottom layer. The first elastic yarn 5 shifts from the top layer to the bottom layer and then to the middle layer. The second elastic yarn 7 shifts from the bottom layer to the middle layer and then to the top layer. Other variations can also be used to create a weave structure that alternates the upper and lower positions, ensuring that each grid cell on the outer surface of the anti-slip band segment 3 contains at least one grid of spandex yarn and at least one grid of elastic yarn. A 2x2 or 2x3 arrangement of grid cells, i.e., each grid cell contains at least one grid of spandex yarn and at least one grid of elastic yarn, means that at least 1 / 4 or 1 / 6 of the spandex yarn is exposed on the surface of the anti-slip band segment 3. This utility model utilizes spandex yarn in the warp yarn to form a specific alternating structure, resulting in a shoulder strap with inherent anti-slip properties. This eliminates the need for external anti-slip coatings or components, and does not require changes to the shoulder strap's shape. Furthermore, the anti-slip performance does not degrade with wear.
[0037] This new design utilizes an improved warp yarn structure, replacing a non-slip coating made of rubber or other materials, while achieving the same anti-slip effect. Compared to coating structures, the shoulder straps of this new design offer improved breathability and comfort. This solution eliminates the coating process, reducing costs and increasing production efficiency. The anti-slip effect is permanent, and the quality of the anti-slip shoulder straps is also improved. Compared to existing solutions that require adding anti-slip buckles or modifying the shoulder strap shape, this new design does not require altering the user's usual wearing habits, making it easier to wear.
[0038] In a specific implementation, the elastic yarn is spandex covered yarn or nylon yarn, and the first elastic yarn 5 and the second elastic yarn 7 can be made of the same or different materials.
[0039] The warp yarn of the above structure and shape not only changes the anti-slip performance between the non-anti-slip belt segment 2 and the anti-slip belt segment 3, but also makes the two have different tensile and rebound mechanical properties. The elongation of the non-anti-slip belt segment 2 is greater than that of the anti-slip belt segment 3. Figure 2 and Figure 3 Taking the warp yarn structure shown as an example, the non-slip segment 2 has an elongation of 175% and a weaker tensile strength, while the non-slip segment 3 has an elongation of 150% and a stronger tensile strength. During daily wear, when the shoulder strap is stretched due to certain movements, the non-slip segment 2 will stretch first. The non-slip segment 3, in contact with the shoulder, is less likely to stretch due to its stronger tensile strength and thus slides. This prevents friction damage to the shoulder skin, ensuring comfortable and safe wearing.
[0040] In a specific implementation, the webbing also includes weft yarns, which connect the three-layer warp yarns into one. The weft yarns are made of spandex-coated yarns. For example, the weft yarns are interspersed in the intervals between the three layers of warp yarns and are interwoven according to a certain pattern.
[0041] In a specific implementation, the length of the anti-slip belt segment accounts for 1 / 3 to 1 / 2 of the total length of the shoulder strap body; this length setting takes into account both anti-slip and tensile rebound mechanical requirements.
[0042] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
