Description

Technical Field

[0001] The utility model relates to the technical field of polyester yarns, in particular to a polyester yarn with flame retardant and antioxidant functions. Background Art

[0002] Polyester fiber, also known as polyester fiber, is a fiber made by spinning polyester, which is formed by the polycondensation of organic dibasic acids and diols. As a key raw material in the textile industry, polyester fiber has largely alleviated the shortage of natural fibers. Polyester fiber has excellent wrinkle resistance, elasticity, dimensional stability, and good electrical insulation properties, making it widely used. Polyester filament products are mainly suitable for covering yarn, socks, yarn, gloves, carpets, curtains, and other fields.

[0003] However, polyester yarn has certain drawbacks during use. The fiber's dense molecular structure and small pores make it difficult for air to penetrate the fabric, resulting in poor breathability. This can further exacerbate the feeling of stuffiness when worn, especially in summer or high-temperature environments. Wearing polyester clothing can be suffocating. Its airtightness also makes it difficult for the skin to breathe, and long-term wear can have certain impacts on skin health. Furthermore, polyester fiber has poor melting resistance. When exposed to fire sources such as soot and sparks, polyester fibers easily form holes, causing damage to clothing and posing a dangerous risk. Polyester fibers are susceptible to oxidation reactions under high temperatures and ultraviolet light. Oxygen molecules attack the polyester molecules, reducing fiber strength and affecting product quality.

[0004] Therefore, a polyester yarn with flame retardant and antioxidant functions is proposed to solve the above problems. Summary of the Invention

[0005] In order to make up for the above shortcomings, the utility model provides a polyester yarn with flame retardant and antioxidant functions, aiming to improve the problem in the prior art that polyester yarn is often used in outdoor and high-temperature environments, where oxidation is more significant and affects the mechanical properties of the polyester yarn.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a polyester yarn with flame retardant and antioxidant functions, including a main yarn, the surface of the main yarn is provided with a waterproof coating, the outer wall of the waterproof coating is provided with a plurality of spirally distributed protective yarns, the protective yarn includes a polyester base yarn, the surface of the polyester base yarn is provided with an antioxidant layer, the surface of the antioxidant layer is wrapped with an isolation layer, and the surface of the isolation layer is wrapped with a mesh-shaped fireproof cloth layer.

[0007] Preferably, the protective wire is spirally wound on the surface of the main wire, and multiple protective wires are closely arranged side by side.

[0008] Preferably, the protective wire is bonded to the main wire by heat pressing.

[0009] Preferably, the waterproof coating is a silicon-based waterproof coating.

[0010] Preferably, the anti-oxidation layer is coated on the surface of the polyester-based yarn by dipping a nano silver ion solution.

[0011] Preferably, the isolation layer is formed by weaving a thin sheet-like composite fiber formed by stacking ceramic fiber and quartz fiber on the surface of the anti-oxidation layer.

[0012] Preferably, the fireproof cloth layer is mesh-shaped and coated on the surface of the isolation layer. The fireproof cloth layer is flat and includes flame-retardant cotton and flame-retardant nylon. The flame-retardant cotton is located between the flame-retardant nylon and the isolation layer.

[0013] The utility model has the following beneficial effects:

[0014] 1. The nano silver ion solution of the antioxidant layer is coated on the surface of the polyester-based yarn, which can absorb and neutralize oxygen free radicals in the air, thereby preventing the polyester yarn from aging due to oxidation;

[0015] 2. Nano silver ion solution also has good antibacterial properties, which can inhibit the growth of bacteria and keep polyester yarn clean and hygienic;

[0016] 3. The fireproof cloth layer is wrapped in a mesh shape on the surface of the isolation layer. The flame-retardant nylon can quickly diffuse heat to prevent heat from being concentrated in one point and causing local overheating of the polyester yarn. At the same time, the flame-retardant cotton absorbs heat and expands between the flame-retardant nylon and the isolation layer to form an insulation layer to prevent heat from being transferred to the main yarn and protective yarn.

[0017] 4. Because the fireproof cloth layer is wrapped in a mesh shape, a grid concave shape is formed on the surface of the polyester yarn. After the weaving, pores are formed between the polyester yarns, thereby improving the moisture absorption and perspiration performance of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Reference Figure 1 The utility model provides an embodiment: a polyester yarn with flame retardant and antioxidant functions, comprising a main yarn 1, which is the core material of the polyester yarn and serves as the basis of the overall structure. A waterproof coating 11 is provided on the surface of the main yarn 1, and the waterproof coating 11 is a silicon-based coating. The waterproof coating 11 adopts a silicon-based coating, which can effectively prevent moisture penetration, protect the main yarn 1 from the influence of a humid environment, and improve its durability and stability. The outer wall of the waterproof coating 11 is provided with a plurality of protective wires 2, which are spirally wound on the surface of the main yarn 1. The protective wire 2 is spirally wound on the surface of the main yarn 1, providing the polyester yarn with additional flame retardant and antioxidant functions. The protective wire 2 is fixed to the main yarn 1 by hot pressing bonding to ensure that each layer of the structure is tightly connected and not easy to fall off, while maintaining good structural integrity and durability.

[0025] Reference Figure 2 The protective wire 2 includes a polyester base wire 21, and the surface of the polyester base wire 21 is coated with an antioxidant layer 22. The antioxidant layer 22 is coated on the surface of the polyester base wire 21 by impregnation with a nano silver ion solution. The polyester base wire 21 serves as the main material of the protective wire 2, and the nano silver ion solution can improve the antioxidant properties of the polyester wire and extend its service life. The surface of the antioxidant layer 22 is wrapped with an isolation layer 23. The isolation layer 23 is woven by wrapping a thin sheet of composite fiber. The composite fiber is stacked with ceramic fiber and quartz fiber. The ceramic fiber and quartz fiber provide excellent thermal insulation and isolation properties, further protecting the main wire 1 and the protective wire 2 from the influence of external heat sources and chemicals. The surface of the isolation layer 23 is wrapped with a fireproof cloth layer 24, and the fireproof cloth layer has a mesh structure.

[0026] Reference Figure 3 The fireproof fabric layer 24 comprises flame-retardant nylon and flame-retardant cotton. The flat layer includes flame-retardant cotton 25 and flame-retardant nylon 26, with the flame-retardant cotton positioned between the flame-retardant nylon and the insulation layer. The flame-retardant nylon enhances the structure's fire resistance, while the flame-retardant cotton further improves the overall flame-retardant effect.

[0027] Working Principle: When the polyester yarn encounters high temperatures, the fireproof fabric layer 24 takes effect first. The flame-retardant nylon rapidly diffuses the heat, preventing it from concentrating in one spot and causing localized overheating of the polyester yarn. Simultaneously, the flame-retardant cotton absorbs heat and expands between the flame-retardant nylon and the isolation layer, forming an insulating layer that prevents heat from transferring to the main yarn 1 and the protective yarn 2.

[0028] The thin sheet structure formed by stacking ceramic fibers and quartz fibers not only has good thermal insulation properties, but also can effectively isolate external chemicals and prevent chemical corrosion to polyester fibers.

[0029] The nano silver ion solution of the anti-oxidation layer 22 is coated on the surface of the polyester base yarn 21, which can absorb and neutralize oxygen free radicals in the air, preventing the polyester yarn from aging due to oxidation. The nano silver ion solution also has good antibacterial properties, can inhibit the growth of bacteria, and keep the polyester yarn clean and hygienic.

[0030] The protective threads 2 are spirally wound around the main thread 1, forming a series of protective lines that not only increase the strength of the polyester thread but also distribute the flame retardant and antioxidant properties more evenly throughout the entire polyester thread. Even if a part of the thread is damaged, the remaining protective threads can still function.

[0031] The main yarn 1 is the core material of the polyester yarn, and the waterproof coating 11 provided on its surface can effectively prevent moisture penetration, keep the polyester yarn dry and stable, so that the polyester yarn can still maintain excellent performance in a humid environment.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
