Introduction To Polyester Fabric

Polyester fabric is a synthetic textile made from polyester fibers, commonly known as "Diqueliang." Its primary component is polyethylene terephthalate (PET), which is processed from petrochemical raw materials through a melt-spinning technique. Due to the dense and symmetrical structure of its molecular chains, this fabric exhibits strong wrinkle resistance, excellent shape retention, and durability against abrasion and heat; consequently, it is widely utilized in the manufacture of products such as outerwear, luggage, and tents. While its hydrophobic nature results in poor moisture absorption (with a moisture regain rate of only 0.4%), this characteristic can be improved through various modification technologies.

Polyester fabrics encompass a wide variety of types. In addition to pure polyester textiles, there are numerous products blended or interwoven with various other textile fibers; these hybrid materials compensate for the shortcomings of pure polyester fabrics, thereby delivering superior performance characteristics. The development of polyester fabrics is trending toward the "naturalization" of synthetic fibers-mimicking the aesthetics and textures of natural materials such as wool, silk, linen, and suede-giving rise to products like polyester imitation silk, imitation wool, imitation linen, and imitation suede fabrics. Following its industrialized mass production in the mid-20th century, polyester gradually evolved into the most widely used synthetic fiber globally. Polyester has a vast range of applications, being extensively utilized in both apparel manufacturing and industrial products. The development of flame-retardant polyester has enabled its application in specialized fields, such as firefighting protective gear and vehicle interiors. Furthermore, composite technologies are employed to endow the fabric with specific functionalities-such as anti-static and water-repellent properties-while blending with natural fibers serves to enhance overall comfort.

To address the challenge of recycling waste polyester and other polyester-based materials, the industry has developed a series of recycling technologies, broadly categorized into physical and chemical methods. The fundamental rationale behind developing recycled polyester is to serve as a substitute for virgin polyester, thereby reducing the demand for petroleum resources and simultaneously alleviating environmental pressure. This initiative has led to the emergence of recycled polyester and plant-based polyester, the raw materials for which are primarily derived from sugarcane and corn. Bio-based polyester-produced from plant-derived raw materials-possesses the same durability and processability as traditional polyester, yet offers the significant advantage of substantially reducing greenhouse gas emissions. These eco-friendly production processes are driving the expansion of polyester's presence within the specialized textiles market.
