What raw material is polyester silk yarn made of?
Polyester yarn is a fiber-forming high-polymer fiber made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. Material - polyethylene terephthalate (PET), fiber filaments made by spinning and post-processing. Polyester silk fabrics are fabrics made of polyester silk as the main material.

The scope of application of polyester silk yarn
Polyester yarn is widely used, and is widely used in clothing, bedding, and various decorative fabrics. Polyester yarn is a synthetic fiber, and its biggest advantage is that it has good wrinkle resistance and shape retention. Good elasticity and almost full recovery after stretching. Very wrinkle-resistant, that is, the fabric does not wrinkle, and has good corrosion resistance, light resistance, and abrasion resistance. Polyester yarn is the world's largest synthetic fiber variety.
The yarn quality of polyester yarn is not more stable than rayon, but more elastic. You can cut the rayon thread for testing, pull it hard, and then relax it, and you will find that the embroidery thread will not shrink; on the contrary, once the stretched polyester thread is relaxed, it will return to its original length, which sometimes causes the flower to wrinkle. In terms of adjustment, it needs to be more accurate.

What is the difference between 100% dope dyed polyester yarn and yarn dyed?
The difference between 100% dope dyed polyester yarn and yarn-dyed polyester yarn lies in the dyeing method of the fiber.
100% dope dyed polyester yarn is a yarn that is colored by adding color to a polymer solution or "dope" before being extruded into fibers. As a result, the color is evenly distributed throughout the fibers, resulting in a more even and consistent colouration. Because the entire yarn is colored, no further dyeing or finishing is required. This method is more efficient, because the entire production process can be completed in one step, and the color of the final product is more uniform.
Yarn-dyed polyester yarn, on the other hand, is a yarn that is colored after it is spun into yarn. The yarn is first spun into yarn, then wound into skeins or packages, and then dyed. This method allows for the creation of intricate patterns and designs, as the yarns can be dyed in different colors and then woven together to form the desired pattern. However, the production of yarn-dyed polyester yarn is more labor-intensive and time-intensive as it requires a separate dyeing step.
In conclusion, the main difference between 100% dope dyed polyester yarn and yarn-dyed polyester yarn is the dyeing method of the fiber, which affects the uniformity and efficiency of the dyeing process.
