The difference between the details of DTY and FDY is that the difference in drafting speed when the fiber is bundled leads to the difference in the process, and there is also a POY here, DTY is a kind of textured yarn belonging to POY, POY after an overfeeding high temperature equipment, it produces a more curly DTY, so the DTY fabric will be softer and fluffier.
The difference in the drafting speed of the fiber leads to the birth of these Ys, the drafting speed of FDY is about twice that of POY, which leads to different changes in the molecular structure of FDY and POY after stretching, FDY fibers are more straight, and POY is relatively more curved.
