Polypropylene BCF silk, commonly known as polypropylene bulk yarn, polypropylene carpet yarn, BCF is the abbreviation of continuous filament, but also not only one step to produce the process of continuous continuous filament filament. Polypropylene BCF wire can be made by several different processes.

Brief introduction of three kinds of production of polypropylene BCF silk process:

First: one step: continuous spinning, stretching, deformation, winding process

Second: two-step method: spinning stretch joint → wire deformation or spinning winding → wire drawing deformation

The third: three-step method: spinning down → → wire drawing → deformation

One step continuous production of polypropylene BCF process requirements: the same time using three screws with the same specifications can be extruded corresponding to the three requirements of different colors of the melt, and then through the distribution pipe to the spinneret, so that each filament from three different Color silk made of compilation, and finally through the continuous tensile deformation made of polypropylene BCF filament.

The two-step or three-step production process is basically similar, that is, a winding bobbin set a color, and then the three color bobbin merger, stretching into polypropylene BCF filament.
