BFF yarn production is carried out using polypropylene chips casting system. By melting this extruder in the extruder and passing the material through the filaments, the filaments formed under hot stretch are about three times (DR = 3). And then wrap around the reel. BFCF yarn as a bulk filament yarn is the best option for replacing acrylic or wool yarn in the manufacture of floor coverings such as (carpet, carpet carpet, jajim, carpet, etc.). If the texturing area is mainly used for hot air flow and excess feeding, the yarn will become flaky. The term is referred to as BCF (bulk continuous filament)
