Mechanized devices designed to modify the physical form of synthetic textile materials by introducing twists, loops, coils, or crinkles into the fiber's filaments, thus improving textile appearance, increasing warmth and absorbency, and lessening pilling. Because there are myriad texturing methods, these devices vary slightly. While some utilize friction disks or spindles and heat to twist fibers, others utilize air streams and high pressure to facilitate the texturing process.
