Polypropylene DTY wire VS PP FDY yarn, what is the difference? Let's learn how to distinguish!

Polypropylene DTY filaments are crimped and polypropylene FDY filaments are straight.

PP FDY yarn elongation and shrinkage are two concepts. Elongation refers to the percentage of polypropylene filament elongation after stress; shrinkage is the percentage ratio of shrinkage length to original length after heating of polypropylene filament. Polypropylene is an important product in synthetic fibers. It is a Chinese name for synthetic polypropylene fibers made from propylene, a by-product of petroleum refining. Also known as polypropylene fiber.

Refers to the incompletely stretched chemical fiber filaments obtained by high speed spinning between the unoriented yarn and the 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 (FDY). FDY is a stretch-deformed yarn. It is made of POY as a raw yarn, and is made by stretching and false twisting. It often has certain elasticity and shrinkage.

PP FDY yarn is environmentally friendly material, non-polluting, non-toxic, environmentally friendly, light weight, chemical resistant, recyclable granulation, etc.

From this point of view, there are some obvious differences between the two, PP FDY yarn has a wide range of applications in our daily lives.
