Description

Technical Field

[0001] This utility model relates to the field of textile yarn, specifically to an anti-loosening ply yarn. Background Technology

[0002] Ply yarn is made by combining and twisting two or more single yarns. Its strength and abrasion resistance are superior to single yarns. Furthermore, ply yarn can be combined and twisted in certain ways to obtain multi-twisted ply yarn. Yarn can be woven into fabrics, and the structure and properties of the yarn directly affect the fabric's performance. For example, fabrics woven from abrasion-resistant yarns have excellent abrasion resistance and are suitable for outdoor fabric production.

[0003] During the use of a fabric, if the yarns become loose or unravel, it can easily lead to pilling and fuzzing on the fabric surface, reducing its appearance and even affecting its overall structure. Simultaneously, yarn slippage can cause the yarns to unravel, impacting the fabric's appearance and lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a non-fraying ply yarn that can ensure the stability of its structure, guarantee the non-fraying properties of the yarn, and reduce the risk of yarn slippage between yarns.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A type of anti-loosening ply yarn, comprising:

[0007] The first fiber yarn has a single yarn structure;

[0008] Several second fiber yarns are wound around the first fiber yarn in turn;

[0009] Several reinforcing units are used to reinforce the second fiber yarn on the first fiber yarn, and each reinforcing unit is arranged at an equal angle around the central axis of the first fiber yarn.

[0010] The second fiber yarn is located between the reinforcing unit and the first fiber yarn. The reinforcing unit includes two third fiber yarns. The third fiber yarns are single yarn structures. The two third fiber yarns are wound around the first fiber yarn at equal intervals along the axial direction to form several first winding points. The two third fiber yarns are wound around each other for half a turn. The third fiber yarns of the two reinforcing units are wound around each other at the middle position of two adjacent first winding points to form a second winding point.

[0011] Furthermore, the second fiber yarn has a ply structure and includes several fiber strips. Each fiber strip is twisted to form the second fiber yarn, and the twisting direction of the fiber strips is the same as the direction in which the second fiber yarn winds around the first fiber yarn.

[0012] Furthermore, the diameter of the first fiber yarn is 5 times the diameter of the second fiber yarn, and the diameter of the second fiber yarn is 3 times the diameter of the third fiber yarn.

[0013] Furthermore, the cross-sections of the first fiber yarn, the fiber strip, and the third fiber yarn are all circular.

[0014] Furthermore, both the first and third fiber yarns adopt a Z-twist structure, while the second fiber yarn adopts an S-twist structure.

[0015] Furthermore, the fiber strip is made of functional fibers.

[0016] Compared with the prior art, this utility model has the following advantages and effects:

[0017] (1) This utility model improves the strength of the yarn by setting up the structure between the first fiber yarn and the second fiber yarn. Combined with the reinforcement effect of the reinforcement unit on the second fiber yarn, it can achieve the purpose of restricting the second fiber yarn from detaching from each second fiber yarn that is wound around the first fiber yarn, thus ensuring the stability of the winding structure of each second fiber yarn on the first fiber yarn, thereby ensuring the anti-detachment property between the first fiber yarn and the second fiber yarn.

[0018] (2) The present invention enables the yarn surface to form a concave-convex structure through the structural arrangement between the second fiber yarn and the reinforcing unit, thereby increasing the friction between the yarns on the fabric and reducing the risk of yarn slippage.

[0019] (3) By combining the first fiber yarn and the second fiber yarn, the second fiber yarn can use functional fibers to form a functional layer (such as waterproof and wear-resistant) on the surface of the first fiber yarn, thereby reducing the amount of functional fibers used and lowering the manufacturing cost while forming functional yarn.

[0020] Figure 1 This is a schematic diagram of the structure of a non-fraying ply yarn according to this utility model.

[0021] Figure 2 yes Figure 1 The diagram shows a partial structural schematic of the second fiber yarn.

[0022] Among them, there are first fiber yarn 1, second fiber yarn 2, fiber strip 21, reinforcing unit 3, third fiber yarn 31, first winding point 4, and second winding point 5. Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] See Figure 1 , Figure 2 This embodiment discloses an anti-loosening ply yarn, comprising a first fiber yarn 1, a plurality of second fiber yarns 2, and a plurality of reinforcing units 3 for reinforcing the second fiber yarns 2 on the first fiber yarn 1. The first fiber yarn 1 has a single yarn structure, and the diameter of the first fiber yarn 1 is 5 times the diameter of the second fiber yarn 2. The second fiber yarns 2 are located between the reinforcing units 3 and the first fiber yarn 1, and each second fiber yarn 2 is wound around the first fiber yarn 1 in turn. Each reinforcing unit 3 is arranged at an equal angle around the central axis of the first fiber yarn 1. Each reinforcing unit 3 includes two third fiber yarns 31, which have a single yarn structure, and the two third fiber yarns 31 are connected along the first fiber yarn 1. The yarns are wound sequentially at equal intervals along the axis to form several first winding points 4, with half a turn between each other. The third fiber yarns 31 adjacent to the two reinforcing units 3 are wound together at the midpoint of two adjacent first winding points 4 to form a second winding point 5. This creates a mesh-like reinforcing structure on the outside of the second fiber yarn 2, preventing the second fiber yarn 2 from detaching from the sequentially wound second fiber yarns 2. This improves the stability of the winding structure of the second fiber yarns 2 on the first fiber yarn 1, ensuring the wrapping effect and strength of the second fiber yarns 2 on the first fiber yarn 1, and guaranteeing the anti-unraveling property between the first fiber yarn 1 and the second fiber yarn 2. Simultaneously, the relative positions of the inner and outer sides of the second fiber yarn 2 and the third fiber yarn 31 allow the yarn surface to form a concave-convex structure, increasing the friction between the yarns on the fabric and reducing the impact of yarn slippage or loosening on the overall stability of the fabric structure.

[0025] See Figure 2 The second fiber yarn 2 has a ply structure, and the diameter of the second fiber yarn 2 is three times the diameter of the third fiber yarn 31. The second fiber yarn 2 includes several fiber strips 21, and each fiber strip 21 is twisted to form the second fiber yarn 2, which improves the structural strength of the first fiber yarn 1. The twisting direction of the fiber strips 21 is the same as the direction in which the second fiber yarn 2 is wound around the first fiber yarn 1, which ensures that the second fiber yarn 2 is wound on the first fiber yarn 1.

[0026] To enhance the functionality of the yarn, the fiber strip 21 can be made of functional fibers. At least two functional fibers are twisted together to form a single yarn with a corresponding function. This yarn, then wound around the second fiber yarn 2, creates a functional layer on the surface of the first fiber yarn 1. For example, the second fiber yarn 2, made of polyester waterproof fiber, can form a waterproof layer when wound around the first fiber yarn 1, giving the fabric a certain degree of waterproofing. Simultaneously, the second fiber yarn 2, in conjunction with the first fiber yarn 1, forms a functional yarn, ensuring the yarn's functional performance while reducing the amount of functional fiber used and lowering manufacturing costs.

[0027] In this embodiment, the first fiber yarn 1 and the third fiber yarn 31 both adopt a Z-twist structure, the second fiber yarn 2 adopts an S-twist structure, and the cross-sections of the first fiber yarn 1, the fiber strip 21 and the third fiber yarn 31 are all circular.

[0028] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
