Reflective Filament Yarn is a composite of high-reflective glass beads and polymer yarn. With its evenly distributed beads, it effectively reflects light from various angles, offering excellent visibility and warning effects. It is ideal for use in outdoor sportswear and gear (such as for jogging, cycling, and riding), workwear for nighttime operations, functional or fashion-forward apparel, as well as reflective tapes, labels, and accessories—enhancing both safety and style in low-light conditions.
