Polyester knitted fabric demonstrates remarkable wrinkle resistance, with its high strength and elasticity ensuring that the fabric remains smooth even with frequent use and daily activities, eliminating the need for frequent ironing and greatly enhancing its durability and practicality. Additionally, its heat resistance, light resistance, wear resistance, and corrosion resistance allow the fabric to maintain stable performance in various environments, making it an ideal material in the clothing industry. Compared to natural fiber materials, polyester knitted fabric has significant advantages in cost control, offering a high cost-performance ratio for both manufacturers and consumers. This characteristic has made it widely used in various clothing production, becoming an indispensable part of the market. Although polyester fabric is somewhat lacking in moisture absorption, which may cause a sense of stuffiness when worn in certain seasons (such as summer) and may generate static electricity in winter, its quick-drying ability after washing, almost no reduction in wet strength, and excellent anti-deformation capability ensure that the fabric is easy to maintain, remaining as good as new, meeting the high-efficiency cleaning needs of modern fast-paced life. As one of the most heat-resistant synthetic fibers, polyester knitted fabric not only possesses thermoplasticity, making it easy to perform various heat treatments and shaping, such as creating permanent pleats in pleated skirts, but also maintains shape stability in high-temperature environments, showcasing outstanding durability and shaping potential. Polyester fabric excels in light resistance, and except for being slightly inferior to acrylic fibers, its sun protection performance far surpasses that of natural fiber fabrics, especially indoors where it is shielded by glass, offering sun protection nearly comparable to acrylic fibers. Moreover, this fabric has strong resistance to acids, alkalis, and other chemicals, and possesses anti-mold and anti-moth properties, providing strong protection for the long-term preservation and use of clothing.
