The difference between polypropylene DTY wire and polypropylene FDY wire!

DTY fiber is curly, FDY fiber is straight.

The elongation and shrinkage of polypropylene DTY yarn are two concepts. Elongation refers to the percentage of polypropylene filament elongation after stress; Shrinkage rate refers to the ratio of the shrinkage length of the polypropylene wire to the original length after heating. Polypropylene fiber is an important variety of synthetic fibers, using petroleum refining by-product propylene as raw materials such as synthetic fibers such as polypropylene fiber Chinese trade name. Also known as polypropylene fiber.

It refers to the chemical fiber filament which is not fully stretched with a degree of orientation between the unoriented filament and the stretched filament obtained by high-speed spinning. 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 twist textured yarn (FDY). Polypropylene DTY yarn is a stretch deformation yarn, is the use of POY as a raw yarn, stretching and false twist deformation processing, often has a certain elasticity and shrinkage.

polypropylene FDY wire is environmentally friendly material, no pollution, non-toxic, with environmental protection, light weight, chemical resistance, recyclable granulation and so on.
