Let us take a look at the definition of Differential PP FDY, which fibers can be Differential PP FDY.

Differential PP FDY generally refer to chemical fibers that are chemically modified or physically deformed.

Modified in the polymerization and spinning process: copolymerization, super-light, ultra-high shrinkage, meta-staining, anti-static, anti-pilling, anti-mildew, anti-bacterial, anti-fouling, Deodorant type, moisture absorption and sweatproof waterproof type, fluorescent color change type, etc. In the spinning, stretching and deformation processes, there are blending, compounding, hollowing, profiled, shrinking, dissimilar, heterochromatic, fine denier, superfine denier, extra coarse denier, coarse detail, three-dimensional crimp, and entanglement. Fibers such as mixed fiber, mixed, mixed color, coated (pine, double, single), flocked yarn, yarn or fiber strip are all categories of differentiation.

Through the above description, we have a new understanding of the definition and types of Differential PP FDY.
