Polyester, acrylic, and other synthetic fibers have become integral parts of modern textiles. Among these, polyester stands out as one of the most widely used varieties. Known in China as the trade name for polyester fiber, it is crafted from polymers derived through processes like esterification or transesterification, using either purified terephthalic acid (PTA) or dimethyl terephthalate (DMT), combined with ethylene glycol (EG).
Once synthesized, this polymer is typically spun into fibers and undergoes various post-treatment processes to enhance its durability and functionality. These fibers are commonly used in making fabrics such as poly-shaded cloth and blackout cloth, which are primarily composed of polyethylene terephthalate (PET). The versatility of polyester lies in its ability to blend seamlessly with natural fibers while retaining excellent resistance to wrinkles, moisture, and sunlight.
As someone who has worked with textiles for years, I’ve seen firsthand how polyester has revolutionized the industry. Its affordability, ease of maintenance, and wide range of applications make it a favorite among manufacturers and consumers alike. Whether you’re looking at curtains that block out light or garments designed for long-lasting wear, polyester plays a crucial role in delivering quality and performance. It’s fascinating to think about how science and technology continue to refine this material, ensuring it remains relevant even as new innovations emerge in the field of textile production.The check valve is used in the piping system, its main function is to prevent the backflow of the medium, prevent the pump and its driving motor from reversing, as well as the release of the medium in the container.
Check valves can also be used to feed pipes where the pressure may rise to exceed the pressure of the main system. Check valve according to the different material, can be applied to a variety of media pipeline.
The check valve is installed on the pipeline, which becomes one of the fluid components of the complete pipeline. The opening and closing process of the valve disc is affected by the transient flow state of the system in which it is located. In turn, the closing characteristics of the disc have an effect on the fluid flow state.
