Description

Technical Field

[0001] This utility model relates to a wear-resistant vortex-spun yarn, belonging to the field of vortex-spun yarn technology. Background Technology

[0002] Vortex spinning uses a high-speed rotating airflow to twist fibers into yarn, offering advantages such as high spinning speed and production efficiency. However, existing vortex-spun yarns generally suffer from weak fiber cohesion and excessive surface fuzz, resulting in poor abrasion resistance. Under repeated friction, they are prone to pilling, fuzzing, and even breakage, shortening the lifespan of textiles and failing to meet the demands of high-intensity applications. Therefore, developing a wear-resistant vortex-spun yarn has become a key challenge. Utility Model Content

[0003] The purpose of this invention is to provide a wear-resistant vortex-spun yarn with high strength and wear resistance.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present invention relates to a wear-resistant vortex-spun yarn, comprising a core yarn, a reinforcing layer, and a wear-resistant layer; The core yarn is a viscose / elastic vortex spun blended yarn; the reinforcing layer is an ultra-high molecular weight polyethylene filament spirally wound around the outside of the core yarn; and the abrasion-resistant layer is nylon fiber coated around the outside of the reinforcing layer.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the nylon fiber is antistatic nylon 6 fiber.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the nylon fiber is antibacterial nylon 6 fiber.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the reinforcing layer further includes aramid 1414 filament.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the aramid 1414 filament and the ultra-high molecular weight polyethylene filament are spirally wound in opposite directions.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: a heat insulation layer is provided between the core yarn and the reinforcing layer.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the heat insulation layer is hollow polyester fiber.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the heat insulation layer is aerogel fiber.

[0012] The beneficial effects of this utility model are as follows: The wear-resistant vortex-spun yarn involved in this utility model achieves functional layering of "basic support, strength enhancement, and wear-resistant protection" through a three-layer composite structure of "core yarn layer - reinforcing layer - wear-resistant layer," specifically solving the problems of wear resistance and strength in vortex-spun yarns. The wear-resistant layer uses nylon fiber, which can significantly improve the yarn's wear resistance. Furthermore, ultra-high molecular weight polyethylene filaments can provide high strength and cut resistance. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of the wear-resistant vortex-spun yarn involved in Example 1; Figure 2 This is a schematic diagram of the structure of the wear-resistant vortex-spun yarn involved in Example 2. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1 Combination Figure 1 This embodiment will be described in detail below. The wear-resistant vortex-spun yarn involved in this embodiment is characterized by comprising a core yarn 1, a reinforcing layer 2, and a wear-resistant layer 3; the core yarn 1 is a viscose / elastic vortex-spun blended yarn; the reinforcing layer 2 is an ultra-high molecular weight polyethylene filament spirally wound around the outside of the core yarn 1; and the wear-resistant layer 3 is nylon fiber covering the outside of the reinforcing layer 2. Nylon fiber has good wear resistance, so it is chosen as the wear-resistant layer; the fiber weight of the wear-resistant layer 3 is 40 count. The ultra-high molecular weight polyethylene filament has high strength and cut resistance, and its fineness is 150D.

[0016] The viscose / elasso blended yarn used in core yarn 1 was prepared on an MVS 870 air-jet vortex spinning machine, with a specific blending ratio of viscose / elasso 80 / 20. The main process parameters for air-jet vortex spinning were: feed ratio 0.98, take-up ratio 1.00, and nozzle air pressure 0.50 MPa. The spinning speed for 19.7 tex yarn was 380 m / min, with a total draft of 213 times; the spinning speed for 14.8 tex yarn was 360 m / min, with a total draft of 284 times. The viscose / elasso vortex blended yarn possesses a certain degree of elasticity, resulting in a certain elongation of the yarn involved in this embodiment, and the fabric prepared has good comfort. The addition of elasso fibers can slightly increase the breaking elongation of the air-jet vortex yarn, mainly due to the high helical crimp morphology and high breaking elongation of the elasso fibers. In this embodiment, the proportion of elastic yarn added is not high, so the improvement in the breaking elongation of the viscose / elastic yarn vortex spun blend is not obvious. The breaking elongation is 11.77% as tested.

[0017] Furthermore, the nylon fiber is antistatic nylon 6 fiber. Antistatic nylon 6 fiber not only provides good wear resistance but also has antistatic properties. Antistatic nylon 6 fiber refers to nylon 6 fiber produced by adding antistatic masterbatch, thereby giving it wear resistance.

[0018] In this embodiment, the yarn underwent an abrasion resistance test (GB / T 21196.2-2007), and the Martindale yarn withstood more than 50,000 abrasion cycles.

[0019] Example 2 Combination Figure 2 This embodiment will be described in detail below. The wear-resistant vortex-spun yarn involved in this embodiment differs from that in Embodiment 1 in that the reinforcing layer 2 further includes aramid 1414 filaments. The aramid 1414 filaments and ultra-high molecular weight polyethylene filaments are spirally wound in opposite directions.

[0020] Furthermore, a heat insulation layer 4 is provided between the core yarn 1 and the reinforcing layer 2. The heat insulation layer 4 is hollow polyester fiber or aerogel fiber. The nylon fiber is antibacterial nylon 6 fiber.

[0021] Antibacterial nylon 6 fiber is made by adding antibacterial agents to nylon 6 fiber, giving it the ability to inhibit bacterial growth. In practical use, this antibacterial property can effectively reduce odors and potential harm to the human body caused by bacterial growth, improving the hygiene and user experience of the yarn.

[0022] Because aramid 1414 filament possesses excellent properties such as high strength, high modulus, and high temperature resistance, when spirally wound with ultra-high molecular weight polyethylene filament in the opposite direction, it can further enhance the overall strength and stability of the yarn. When subjected to external forces, the two work together to disperse stress, thereby improving the yarn's ability to resist breakage and deformation.

[0023] The insulation layer 4, located between the core yarn 1 and the reinforcing layer 2, provides excellent insulation whether it is made of hollow polyester fiber or aerogel fiber. The hollow structure inside the hollow polyester fiber effectively prevents heat transfer, while aerogel fiber is known for its extremely low thermal conductivity. This reduces heat transfer to the core yarn when the yarn is used in high-temperature environments, protecting the core yarn's performance from the effects of high temperatures.

[0024] In antibacterial performance tests, the inhibition rate against common bacteria such as Escherichia coli and Staphylococcus aureus reached over 95%, demonstrating the excellent antibacterial effect of antibacterial nylon 6 fiber. Furthermore, the Martindale abrasion resistance of this yarn was comparable to that of Example 1.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
