BCF is an acronym for Bulked Continuous Filament and refers to synthetic fibers in a continuous form - miles long, formed into yarn bundles of a given number of filaments and texturized to increase bulk and cover. Texturizing changes the straight filaments into kinked or curled configurations.
Since BCF already arrives as a single yarn, it is normally twisted with another yarn (two-ply) and bulked before being heat set. Bulking is processing yarn to fluff it up and give more coverage with the same weight. Bulking also adds to fiber resiliency. Crimping creates “bulk” in individual filaments by creating a saw-tooth, zigzag or random curl relative to the fiber.
