Polyester fabric is a synthetic fiber made from PTA, DMT, and MEG as raw materials, which has the advantages of being sturdy, durable, elastic, and wear-resistant. It is widely used in fields such as clothing, decoration, and automobiles. The production process includes spinning, winding, and post-processing. Although it has disadvantages such as poor moisture absorption and easy pilling, its performance continues to improve through improved processes and the development of additives.
Polyester fabric, also known as polyester fiber, is an important variety of synthetic fibers in the world today. It is a fiber forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or ester exchange and condensation reactions, and then spun and post-treated to produce fibers.
The advantages of polyester fabric are sturdy and durable, not easily deformed, wear-resistant and durable, good dimensional stability, and good electrical insulation performance, as well as good resistance to sunlight and climate. In addition, the stretchiness, wrinkle resistance, shape retention, and wear resistance of polyester fabric make it the preferred material for making men's and women's clothing, especially suitable for making outerwear.
The production process of polyester fabric includes three main processes: spinning, winding, and post-processing. Spinning is the process of continuously and uniformly sending the polymerized polyester melt to the spinning box through a spinning pump, then spraying out a fine filament flow through a spinneret, and solidifying into filaments under the cooling effect of side blowing air. Coiling is the process of winding the filaments produced by the spinning process into cylindrical tubes of a certain shape and capacity for storage, transportation, and post-processing. Post processing includes processes such as stretching, heat setting, and curling to further improve the physical properties and appearance quality of polyester fabrics.
The performance of polyester fabrics is influenced by factors such as their fiber structure, fiber morphology, and fiber cross-sectional morphology. For example, the higher the crystallinity and orientation of polyester fibers, the better their mechanical and thermal properties. In addition, the moisture absorption, breathability, and dyeing properties of polyester fabrics can also be improved through different production processes and additives.
However, polyester fabrics also have some drawbacks. For example, it has poor moisture absorption, is prone to static electricity, is prone to pilling, and is prone to dust accumulation. In addition, polyester fabrics have poor heat resistance and are not suitable for long-term use at high temperatures. Therefore, when using polyester fabric, it is necessary to pay attention to its maintenance and cleaning methods to avoid these problems.
Overall, polyester fabric is a high-performance and versatile synthetic fiber. Although it has some drawbacks, the performance of polyester fabrics has been continuously improved and perfected through continuous production process improvement and additive research and development. In the future, with the continuous progress of technology and people's pursuit of high-quality life, polyester fabrics will be applied and developed in more fields.
