False twisted silk composition
Jul 13, 2018

POY: Pre-oriented yarn, full name: pre-oriented yarn or partially oriented yarn. It refers to an incompletely stretched chemical fiber filament obtained by high speed spinning between an unoriented yarn (UDY) and a drawn yarn. Compared with undrawn yarn, it has a certain degree of orientation and good stability, and is often used as a special yarn for stretching false twisted textured yarn (DTY). (generally not used for weaving)


FDY: Fully drawn yarn. Full name: fully draw yarn. Synthetic fiber filaments further prepared by spinning and drawing. The fibers are fully stretched and can be used directly in textile processing. (usually called it filament)


POY and FDY: The spinning speed of high-speed spinning is 3000~6000m/m in, and the winding speed of spinning speed below 4000m/min is higher, which is pre-oriented yarn. It is called POY (pre-oriented yarn). ). If a stretching action is introduced during the spinning process, a wound wire having a high degree of orientation and a medium crystallinity can be obtained, which is a fully drawn yarn, generally referred to as FDY (fully drawn yarn).
