Polypropylene air change yarn is polypropylene fiber and polyester air change yarn is polyester fiber.

Polyester air change yarn a synthetic fiber derived from polyester polycondensation of organic diacid and diol by spinning. PET fiber for short, is the current synthetic fiber of the first variety. In addition, its advantages are wrinkle resistance and conformal property is very good, with high strength and elastic recovery ability. It is firm and durable, wrinkle-resistant and ironing free.

Polypropylene (PP) is a fiber made from propylene by polymerization and melt spinning. Industrial production of polypropylene (PP) began in 1957 and is a latecomer among synthetic fibers. Because polypropylene has the advantages of simple production process, cheap products, high strength, relatively light density, so the development of polypropylene is fast. At present, polypropylene is the fourth largest variety of synthetic fiber.

The production of polypropylene includes staple fiber, polypropylene high strength filament, polypropylene air filament and so on.
