High-strength polyester industrial filament: Industrial fibers suitable for the needs of the Start of Autumn!

After the Start of Autumn, the summer heat gradually subsides. Outdoor construction, logistics transportation and other operations enter a busy period due to the cooler climate. At the same time, the increase in autumn rain and the larger temperature difference between day and night put forward higher requirements for the strength and weather resistance of industrial materials. High-strength polyester industrial filament is an industrial fiber made from polyester through special spinning and high-factor stretching processes. With its excellent mechanical properties and environmental adaptability, it precisely meets the industrial production and outdoor application requirements during the Start of Autumn season, becoming a key material in multiple fields.

From the perspective of production process, the manufacturing of High-strength polyester industrial filament is in line with the usage scenarios after the Start of Autumn. It is made from high-viscosity polyester chips as raw materials, and after drying treatment (suitable for the dry air environment after the Start of Autumn to reduce the influence of moisture absorption of raw materials), it is melted and spun at 280-300℃. Subsequently, through high-intensity stretching at 5 to 8 times, the macromolecular chains within the fibers are highly oriented, significantly enhancing the breaking strength. Finally, after high-temperature shaping treatment, the dimensional stability of the fibers is enhanced - the high strength and anti-shrinkage property endowed by this process can cope with the frequent force and material deformation caused by the temperature difference between day and night during outdoor operations after the Start of Autumn.

In terms of core performance, high-strength polyester industrial filament is highly compatible with the demands of the Start of Autumn season. Its breaking strength is 3 to 5 times that of ordinary polyester filament, which is suitable for the high-strength requirements of material load-bearing and traction in outdoor construction (such as geotechnical engineering and cable laying) after the Start of Autumn. It has excellent weather resistance, capable of withstanding the still strong ultraviolet rays after the Start of Autumn and intermittent autumn rain, preventing fiber aging or moisture degradation. In addition, it has a low hygroscopicity (with a moisture regain rate of about 0.4%), is not prone to mold in the humid environment of autumn rain, and has strong dimensional stability. Even after experiencing temperature differences between day and night, it is not easy to shrink or deform, ensuring the structural stability of industrial products.

In terms of application scenarios, High-strength polyester industrial filament is suitable for diverse demands after the Start of Autumn. In the field of outdoor construction, it can be used to make geotextiles and safety belts, providing support for engineering safety with high strength and weather resistance. In the field of logistics and transportation, as the raw material for container binding straps and lifting ropes, it can meet the high-frequency load-bearing demands during the logistics peak season after the Start of Autumn. In the field of flood control, the flood control sandbags and anti-seepage fabrics made from it can resist the dampness and impact brought by autumn rain. In addition, in industrial components such as tire cord and drive belts, it can also meet the demand for increased industrial production load after the Start of Autumn with its high modulus characteristics.

With the adjustment of industrial demand after the Start of Autumn, high-strength polyester industrial filament is also being optimized and upgraded. The strength is further enhanced by improving the stretching process, making it suitable for outdoor heavy-duty operations. Introduce anti-ultraviolet and anti-hydrolysis modifications to enhance the resistance to autumn rain and light. At the same time, develop fine denier and high-strength varieties to meet the lightweight demands of some precision industrial components after the Start of Autumn, providing more reliable fiber support for industrial production during the transition period of the solar terms.
