about BCF yarn
BCF is an acronym for Bulked Continuous Filament. BFC is synthetic PP fibers in a continuous form. Production is similar to CF Yarns, but filaments are texturized to increase bulk and cover. Texturizing changes the straight filaments into kinked or curled configurations.
Bulking is processing yarn to fluff it up and give more coverage with the same weight. Bulking also adds to fiber resiliency.
