In today's rapidly developing textile industry, polyester industrial yarn has become an indispensable and important material with its excellent performance, wide application fields and continuous technological innovation.
Polyester industrial yarn, mainly made of polyethylene terephthalate (PET) fiber, has a series of excellent properties such as high strength, high modulus, wear resistance, corrosion resistance, wrinkle resistance, easy washing and quick drying. These characteristics make polyester industrial yarn perform well in industrial production and can meet various complex and harsh use environments. Polyester industrial yarn also has good spinnability and weavability, which is easy to process into products of various shapes and specifications.
Polyester industrial yarn can be divided into many types according to its fineness, structure, performance and other characteristics. For example, high-strength, low-strength polyester industrial yarn is mainly used in high-strength applications such as tire cords, conveyor belts, and canvas warps; high-modulus, low-shrinkage polyester industrial yarn has a tendency to gradually replace ordinary standard polyester industrial yarn in tires and mechanical rubber products due to its high breaking strength, high elastic modulus, and low elongation; high-strength, low-shrinkage polyester industrial yarn shrinks less after heating, and the fabric or woven rubber products have good dimensional stability and heat resistance, and are widely used in coated fabrics, conveyor belt wefts and other fields.
The production technology of polyester industrial yarn has undergone a transformation from solid-phase polycondensation chip spinning to melt direct spinning. Melt direct spinning technology eliminates the processes of cooling pelletizing, solid-phase polycondensation, and melt extrusion, and has a compact process flow, which improves production efficiency and reduces production energy consumption and equipment investment. Melt direct spinning technology can also produce high-performance polyester industrial yarns with quality indicators that meet national standards. With the continuous advancement and innovation of technology, the production of polyester industrial yarn will be more efficient, environmentally friendly, and intelligent.
Polyester industrial yarn has shown a wide range of application value in many fields with its unique properties. In the tire industry, high-strength, low-strength and high-modulus, low-shrinkage polyester industrial yarns are used as cords and skeleton materials to improve the strength and wear resistance of tires; in the field of conveyor belts and canvas, polyester industrial yarns are used as warps and wefts to enhance the bearing capacity and service life of products; in the fields of coated fabrics and advertising light box cloths, high-strength, low-shrinkage polyester industrial yarns are favored for their good dimensional stability and heat resistance. Polyester industrial yarns are also widely used in many fields such as automotive seat belts, conveyor belts, fishing nets, and building reinforcement materials.
With the development of the global economy and the continuous changes in consumer demand, polyester industrial yarns will develop in the direction of higher performance, more functions, and more environmentally friendly and low-carbon. On the one hand, enterprises will continuously improve the performance and quality of polyester industrial yarns through technological innovation and industrial upgrading to meet the market demand for high-quality textiles; on the other hand, enterprises will also focus on green production and resource recycling to promote the industry to develop in a more environmentally friendly and low-carbon direction. In the future, polyester industrial yarns will show their unique charm and value in more fields and contribute more to the sustainable development of the textile industry.
