Description

Technical Field

[0001] The utility model relates to the field of yarns, and more specifically, to an anti-loosening yarn. Background Art

[0002] Yarn is the raw material used to weave fabrics. The material and structure of the yarn will affect the structure and performance of the fabric. For example, after being woven into the fabric, if the connection strength between the yarns is insufficient, the yarns are prone to deviation, which may lead to the yarns becoming detached from each other.

[0003] In the prior art, slub yarn is a yarn that forms several slub structures on the yarn through twist changes. Because of its concave-convex structure, the connection strength between the yarns is improved after being woven into a fabric, and the anti-unraveling property of the fabric is improved. However, because the twist at the slub structure of the slub yarn is low, uneven dyeing will occur during dyeing.

[0004] Therefore, the utility model provides another technical solution to solve this technical problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a yarn that prevents unraveling.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: an anti-unraveling yarn, including a core fiber yarn, a plurality of first fiber yarns and a second fiber yarn are wrapped around the core fiber yarn, the diameter of the second fiber yarn is at least twice the diameter of the first fiber yarn, the number of the first fiber yarns is at least five times the number of the second fiber yarns, and the first fiber yarn and the second fiber yarn are twisted in the same direction.

[0007] The utility model is further configured as follows: a reinforcing fiber filament is wound around the outside of the core fiber filament, and the first fiber filament and the second fiber filament are located between the reinforcing fiber filament and the core fiber filament.

[0008] The utility model is further configured as follows: the twist direction of the reinforcing fiber filaments is opposite to the twist direction of the first fiber filaments.

[0009] The utility model is further configured as follows: a plurality of grooves are provided on the surface of the second fiber filaments.

[0010] The utility model is further configured as follows: the diameter of the core fiber filament is greater than the diameter of the first fiber filament.

[0011] The utility model is further configured as follows: the first fiber filament and the second fiber filament are both made of cationic polyester.

[0012] In summary, the utility model has the following beneficial effects: in the length direction of the yarn, the twist of each section of the yarn is the same, which ensures the uniformity during dyeing; the diameter difference between the first fiber filament and the second fiber filament forms a concave-convex structure on the outside of the core fiber filament, which improves the connection strength between the yarns; at the same time, the first fiber filament with a density greater than that of the second fiber filament clamps the second fiber filament in the middle, maintaining the stability of the structural size of the second fiber filament; by increasing the diameter of the core fiber filament, the surface area of ​​the yarn is increased, and the dyeing efficiency of the yarn is improved; the cationic polyester has good dyeing rate and color fastness, which improves the dyeing effect of the yarn.

[0015] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Embodiment: a kind of anti-loosening yarn, such as Figure 1 As shown, it includes a core fiber filament 1, a plurality of first fiber filaments 2 and a second fiber filament 3 are wound around the core fiber filament 1, the diameter of the second fiber filament 3 is at least twice the diameter of the first fiber filament 2, the number of the first fiber filaments 2 is at least five times the number of the second fiber filaments 3, the first fiber filament 2 and the second fiber filament 3 are twisted in the same direction, the diameter of the core fiber filament 1 is greater than the diameter of the first fiber filament 2, and the first fiber filament 2 and the second fiber filament 3 are both made of cationic polyester.

[0017] Specifically, the core fiber filament 1 is made of polyester fiber filament, and seven first fiber filaments 2 and one second fiber filament 3 are wrapped around the core fiber filament 1. The first fiber filament 2 and the second fiber filament 3 are both S-twisted. In the length direction of the yarn, the twist of each section of the yarn is the same, which ensures the uniformity during dyeing. The diameter difference between the first fiber filament 2 and the second fiber filament 3 forms a concave-convex structure on the outside of the core fiber filament 1, which improves the connection strength between the yarns. At the same time, the first fiber filament 2 with a density greater than the second fiber filament 3 clamps the second fiber filament 3 in the middle to maintain the stability of the structural size of the second fiber filament 3. By increasing the diameter of the core fiber filament 1, the surface area of ​​the yarn is increased, and the dyeing efficiency of the yarn is improved. Cationic polyester has good dyeing rate and color fastness, which improves the dyeing effect of the yarn.

[0018] like Figure 1As shown, a reinforcing fiber filament 4 is wrapped around the core fiber filament 1, the first fiber filament 2 and the second fiber filament 3 are located between the reinforcing fiber filament 4 and the core fiber filament 1, the twist direction of the reinforcing fiber filament 4 is opposite to that of the first fiber filament 2, and a plurality of grooves are provided on the surface of the second fiber filament 3.

[0019] Specifically, the reinforcing fiber yarn 4 adopts Z twist, and the reinforcing fiber yarn 4 is made of nylon fiber yarn. The reinforcing fiber yarn 4 coated on the outermost layer limits the second fiber yarn 3 from detaching from the first fiber yarn 2. At the same time, two twisting fibers are arranged on the yarn to ensure the anti-dispersion property between the fibers. The second fiber yarn 3 is a shaped fiber obtained by changing the shape of the spinneret hole during extrusion molding. The groove increases the roughness of the surface of the second fiber yarn 3 and improves the connection strength between the fibers.

[0020] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
