How is a polypropylene BCF wire?

Production of polypropylene BCF wire: continuous spinning, stretching, deformation, and winding process production route can be divided into three types:

Production of polypropylene BCF wire: spinning stretching combined with a filament deformation or spinning winding

Production of polypropylene BCF wire three-step method: spinning drum one-stranded wire stretch

One-step method is similar to the process of production. Spinning and conventional spinning. A color of a winding tube, then combines three different colors, or stretching, or deformed into BCF. However, one-step process is different, but the process requires three screws to extrud out three demanded melt, and then distribute the split to the spinneret by dispensing tube, so that each filament has three different colors, and then The spinning of a step BCF is continuously stretched.
