Application effect of nanographene in polyester hot melt wire
In today’s textile industry, with the continuous advancement of science and technology and the increasing requirements of consumers for textile performance, the research and development and application of new materials have become one of the key factors to promote the development of the industry. As a new material with unique properties, nanographene has gradually attracted attention in the application research of the textile field in recent years. Especially in polyester hot melt wire, the application of nanographene has shown remarkable effects, providing a new way to improve the performance and expand the functions of textiles.

1. Characteristics of nanographene
Nanographene is a two-dimensional nanomaterial with excellent mechanical, thermal, electrical and optical properties. Its unique sheet structure gives it a large specific surface area and can form a good interface with the matrix material. Nanographene has extremely high mechanical strength, good toughness and elasticity, and can significantly improve the mechanical properties of composite materials. In addition, nanographene also has good electrical and thermal conductivity, as well as certain antibacterial and UV resistance, which make it have broad application prospects in the textile field.

2. Application effect of nanographene in polyester thermal melt

(I) Improving mechanical properties
The addition of nanographene can significantly improve the breaking strength and elongation of polyester thermal melt. During the composite process, nanographene can form a good dispersion and orientation arrangement in the polyester matrix, and form a close bond with the polyester molecular chain. This bond can effectively transmit stress, enhance the bearing capacity of the fiber, and thus improve the breaking strength of the fiber. At the same time, the toughness of nanographene can also make the polyester thermal melt have better ductility during the stretching process and reduce the risk of fracture. Studies have shown that adding an appropriate amount of nanographene can increase the breaking strength of polyester thermal melt by more than 15% and the elongation by about 10%.

(II) Enhancing thermal properties
Polyester thermal melt is prone to thermal degradation and melting in high temperature environments, affecting its performance and life. Nanographene has good thermal stability and thermal conductivity, which can increase the thermal decomposition temperature and thermal conductivity rate of polyester thermal melt. Nanographene forms a heat-conducting network in the polyester matrix, which can quickly conduct heat away, reduce the temperature gradient inside the fiber, and reduce local overheating. This helps to improve the dimensional stability and mechanical properties of polyester thermal fuse under high temperature conditions and extend its service life. Experimental results show that the thermal decomposition temperature of polyester thermal fuse with the addition of nanographene can be increased by more than 30°C.

(III) Improve electrical properties
Nanographene has excellent conductivity and can give polyester thermal fuse good antistatic properties. In textiles, static electricity has always been an important concern. Static electricity not only affects wearing comfort, but also may cause safety hazards such as dust absorption and fire. The addition of nanographene can form a conductive path on the surface of polyester thermal fuse, allowing the charge to leak quickly, thereby effectively inhibiting the generation and accumulation of static electricity. In addition, the conductivity of nanographene can also provide a basis for the application of polyester thermal fuse in the field of smart textiles, such as wearable devices, sensors, etc. By combining with electronic components, the intelligent function of textiles can be realized.

(IV) Improved antibacterial properties
Nanographene has certain antibacterial properties and can inhibit the growth and reproduction of bacteria on the surface of polyester hot melt yarn. Its antibacterial mechanism is mainly through the interaction with the bacterial cell membrane, destroying the structure and function of the cell membrane, and causing bacterial death. In textiles, the improvement of antibacterial properties is of great significance for preventing odor and reducing skin disease infections. Especially in fields with high hygiene requirements such as sportswear and medical supplies, polyester hot melt yarns with added nanographene can provide better antibacterial protection and increase the added value of products.

(V) Enhanced anti-ultraviolet performance
Nanographene can absorb and scatter ultraviolet rays, thereby improving the anti-ultraviolet performance of polyester hot melt yarns. Ultraviolet rays have an aging effect on textiles, causing problems such as fiber brittleness and fading. The presence of nanographene in polyester hot melt yarns can block the penetration of ultraviolet rays, reduce the damage of ultraviolet rays to fibers, and extend the service life of textiles. At the same time, for outdoor products that need to be exposed to the sun for a long time, such as parasols and outdoor tents, the use of polyester hot melt yarn with added nanographene can provide better UV protection and meet consumers’ needs for health and safety.

3. Application Cases

(I) Sportswear
In the field of sportswear, the performance requirements for textiles are high, and they need to have good air permeability, moisture absorption, elasticity and wear resistance. A sports brand uses polyester hot melt yarn with added nanographene as the main fabric in its new sportswear. The results show that this kind of clothing has better comfort and durability during wearing, and can effectively absorb and dissipate the heat and sweat generated by human exercise to keep the body dry. At the same time, the antibacterial properties of nanographene also reduce the generation of odor, improve the hygiene performance of sportswear, and have been widely praised by consumers.

(II) Smart Textiles
With the development of intelligent technology, smart textiles have gradually become a hot spot for research and application. Researchers compounded nanographene with polyester hot melt yarn to prepare smart fabrics with conductive properties. This fabric can be combined with electronic components such as sensors and chips to realize functions such as monitoring human physiological signals and sensing environmental parameters. For example, a smart garment based on nanographene/polyester hot melt can monitor physiological indicators such as heart rate and breathing rate in real time, and transmit data to mobile phone applications via Bluetooth, which provides convenience for health management and sports guidance. In addition, the application of smart textiles in the fields of military, aerospace, etc. also has broad prospects, such as making special clothing with functions such as concealed communication and environmental adaptation.

(III) Outdoor products
For outdoor products such as parasols and outdoor tents, UV resistance and durability are important performance indicators. An outdoor product manufacturer uses polyester hot melt material with nanographene added in its products. After testing, the anti-ultraviolet ability of this parasol has been significantly improved, which can effectively block more than 98% of ultraviolet rays, providing users with good sun protection. At the same time, nanographene enhances the mechanical properties of polyester hot melt, making the parasol more durable and able to withstand severe weather conditions such as strong winds, extending the service life of the product. Outdoor tents are also exposed to ultraviolet rays and wear and tear from the natural environment during use. Tents made of polyester hot melt yarn modified with nanographene not only have better UV resistance, but also have good waterproof, windproof and thermal insulation properties, providing outdoor enthusiasts with a safer and more comfortable outdoor experience.

4. Conclusion
The application of nanographene in polyester hot melt yarn has shown significant effects in many aspects, including improving mechanical properties, enhancing thermal properties, improving electrical properties, improving antibacterial properties and enhancing UV resistance. The improvement of these properties makes polyester hot melt yarn have a wider application prospect in the fields of traditional textiles and emerging smart textiles, outdoor products and other fields. With the continuous development of nanotechnology and the reduction of costs, the application of nanographene in polyester hot melt yarn is expected to be further promoted and deepened, providing more possibilities for the innovative development of the textile industry.
