(Bulk Continuous Filament); An infinite filament; BCF, which is the main raw material, is dosed with masterbatch paint to polypropylene and after homogenous mixture is obtained by extrusion method, it is pumped from flat molds into filaments.

The filamentized polypropylene is subjected to a sudden cooling and crystallization of the material is ensured. In the first step, the unstable and flat filament is applied to the fibers by applying blending oil and passing through the hot godetes, the filaments are given strength.
