Luminous our lightly luxurious stretch yarn inspired by Eastern satin collections. Using a white-factory silk stretch fiber wrapping process, it precisely combines 7% top-grade mulberry silk’s golden luster, 86% high-count viscose’s fluid drape, and 7% PBT’s smart memory elasticity. The PBT fibers spiral-wrap like Song brocade’s subtle patterns, keeping the jewel-like sheen of real silk while giving the yarn shaping power beyond traditional silk. It redefines a fabric philosophy where “collector-level shine” meets “futuristic functionality.”
