Abstract
Description
Technical Field
[0001] This utility model relates to the field of underwear fabric technology, specifically to an anti-slip fabric for underwear shoulder straps. Background Technology
[0002] To achieve anti-slip functionality, existing bra straps typically employ a hot-pressed composite of anti-slip silicone strips onto the base band surface. However, the silicone strips can cause localized pressure concentration, leading to indentations and discomfort after prolonged wear. Furthermore, the composite layer structure is prone to peeling and delamination under repeated stretching, resulting in a short lifespan. Continuous anti-slip silicone strips covering the entire strap area hinder sweat evaporation and become ineffective as they lose their lubricating properties due to skin sweat during exercise. Utility Model Content
[0003] Therefore, in order to address the above problems, this utility model provides an anti-slip fabric for bra straps, which solves the problems of discomfort, short lifespan and limited use scenarios caused by design defects in existing bra straps.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] A non-slip fabric for bra straps includes a strap body, wherein high-elastic sections and non-slip sections are periodically alternating along the length of the strap body; the high-elastic sections are made of warp-knitted weft-inserted weave, and the elongation of the high-elastic sections along the length of the strap body is 180%-250%; the non-slip sections are made of weft-knitted jacquard weave, and the surface is formed with continuously distributed soft raised units, the center of each soft raised unit forming a downwardly recessed bearing area, and the edges of each soft raised unit forming annular raised ridges; adjacent high-elastic sections and non-slip sections are connected by a gradient transition section.
[0006] Furthermore, the weaving density of the gradient transition section increases linearly from the high-elasticity section to the anti-slip section.
[0007] Furthermore, the shoulder strap body is integrally molded.
[0008] Furthermore, the ratio of the length of the high-elasticity section to the length of the anti-slip section is 0.4-0.6.
[0009] Furthermore, the surface of the bearing area is dotted with anti-slip adhesive.
[0010] Furthermore, reflective yarn is embedded inside the main body of the shoulder strap, and the direction of the reflective yarn is at an angle of 30°-60° to the length direction of the main body of the shoulder strap.
[0011] Furthermore, the two sides of the shoulder strap body are provided with edging, and the breaking strength of the yarn of the edging is higher than the breaking strength of the central area of the shoulder strap body.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model can automatically adjust the anti-slip strength by periodically alternating between high-elasticity sections and anti-slip sections: there is a difference in elongation between the high-elasticity sections and the anti-slip sections. The greater the elongation, the greater the width change when stretched. When stretched, the width change of the high-elasticity section is greater than that of the anti-slip section, which will cause the annular ridges on the anti-slip section to flip outward. The greater the tension, the more significant the flipping of the annular ridges, making the coverage area of the soft convex unit larger and the anti-slip effect better. The structural design of combining high-elasticity sections with anti-slip sections eliminates the need for composite silicone anti-slip strips and has high breathability.
[0014] 2. This utility model smoothly transmits tensile deformation through a gradient transition section, avoiding breakage at the junction.
[0015] 3. This utility model applies anti-slip adhesive to the load-bearing area, which increases the anti-slip performance when the shoulder strap body is stretched to the point where the load-bearing area comes into contact with the skin. Due to the setting of the soft convex unit, even if the applied anti-slip adhesive fails, the soft convex unit can still play a role, making it widely applicable.
[0016] 4. This utility model uses high-strength locking to prevent the shoulder strap body from tearing at the edges and to prevent deformation after repeated washing. Attached Figure Description

[0018] Explanation of icon numbers:
[0019] Shoulder strap body 1; Overlock 11;
[0020] High-elasticity section 2;
[0021] Anti-slip section 3;
[0022] Soft convex unit 4; bearing area 41; anti-slip rubber 411; convex ridge 42;
[0023] Gradient transition section 5. Detailed Implementation
[0024] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] Example:
[0026] like Figure 1As shown, an anti-slip fabric for bra straps includes a strap body 1, which is integrally molded. The strap body 1 has periodically alternating high-elastic sections 2 and anti-slip sections 3 along its length. The high-elastic sections 2 are warp-knitted with weft-inserted weave, and the high-elastic sections 3 have an elongation of 180%-250% along the length of the strap body 1. The anti-slip sections 3 are weft-knitted jacquard weave, with continuously distributed soft raised units 4 formed on their surface. Each soft raised unit 4 has a downwardly recessed bearing area 41 at its center, and the edges of each soft raised unit 4 have raised annular ridges 42. Adjacent high-elastic sections 2 and anti-slip sections 3 are connected by a gradient transition portion 5.
[0027] The soft convex unit 4 can be a geometric shape such as a circle, quadrilateral, or hexagon. In this embodiment, the soft convex unit 4 is an octagon.
[0028] By periodically alternating between the high-elasticity section 2 and the anti-slip section 3, the anti-slip strength can be automatically adjusted. There is a difference in elongation between the high-elasticity section 2 and the anti-slip section 3. The greater the elongation, the greater the width change when stretched. When stretched, the width change of the high-elasticity section 2 is greater than that of the anti-slip section 3, which will cause the annular ridge 42 on the anti-slip section 3 to flip outward. The greater the tension, the more significant the flipping of the annular ridge 42, making the coverage area of the soft convex unit 4 larger and the anti-slip effect better. The structural design of using the high-elasticity section 2 combined with the anti-slip section 3 eliminates the need for composite silicone anti-slip strips and has high breathability.
[0029] The weaving density of the gradient transition section 5 increases linearly from the high-elasticity section 2 to the anti-slip section 3; the gradient transition section 5 smoothly transmits tensile deformation and avoids breakage at the junction.
[0030] The length ratio of the high-elastic section 2 to the anti-slip section 3 is 0.4-0.6. This length ratio is adjusted according to the underwear size and is not specifically limited in this application. The elongation rate of the high-elastic section 2 is also the same. In order to avoid the difference between the width deformation of the high-elastic section 2 and the anti-slip section 3 after elongation being too large, a width ratio is set between the high-elastic section 2 and the anti-slip section 3, preferably 1.2:1.
[0031] The surface of the bearing area 41 is dotted with anti-slip adhesive 411. When the bearing area 41 is dotted with anti-slip adhesive 411, the anti-slip performance is increased when the shoulder strap body 1 is stretched to the point that the bearing area 41 comes into contact with the skin. Due to the setting of the soft convex unit 4, even if the dotted anti-slip adhesive 411 fails, the soft convex unit 4 can still play a role, and has a wide range of applications.
[0032] In other preferred embodiments, the shoulder strap body 1 is inlaid with reflective yarn (not shown in the figure), and the direction of the reflective yarn is at a 60° angle to the length direction of the shoulder strap body; the reflective yarn can improve the visibility distance at night, and when used in swimwear products, it can improve the safety of users at night.
[0033] The shoulder strap body 1 has locking edges 11 on both sides. The yarn breaking strength of the locking edge 11 is higher than the breaking strength of the central area of the shoulder strap body 1. The high-strength locking edge 11 prevents the shoulder strap body 1 from tearing at the edge and avoids deformation after repeated washing.
[0034] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
