Brief introduction of polypropylene BCF yarn:

Polypropylene BCF yarn is also called polypropylene bulked yarn. It has rich varieties, good bulking effect, uniform network, complete color varieties, and can be customized according to customer requirements. The polypropylene bulked yarn produced by the company can not only be used in the weaving of carpets and car mats, but also can be widely used in various decorative fabrics, weaving, fabrics, door and window tops, etc. After the polypropylene bulked yarn is twisted and shaped, the yarn is plump and has good resilience. It is suitable for cut pile carpets and can obtain the effect of nylon carpets.

How is polypropylene BCF yarn produced?

The production routes of polypropylene BCF yarn can be divided into the following three types:

One-step method: continuous spinning, drawing, texturing, winding process

Two-step method: Spinning and stretching combined with one yarn deformation or spinning and winding one yarn with stretching deformation

Three-step method: spinning, doffing, stretching, and deforming

The two-step production process is similar to the two-step production process. Spinning is the same as conventional spinning. One winding bobbin has one color, and then three bobbins of different colors are combined and stretched or deformed into BCF. However, the one-step method for continuous high-yield BCF is different. This process requires three screws to extrude the melts of three required colors, and then distribute them to the spinneret through the distribution pipe, so that each filament has three filaments of different colors. After continuous stretching and deformation, one-step BCF spinning.
