For 3D bed sheets, the material choice is critical for both the visual effect and tactile feel. 100% Brushed Microfiber is the most common choice because its fine fibers hold disperse dyes exceptionally well, resulting in vibrant, high-definition 3D visuals that do not fade easily. If you are targeting a premium market, look for high-thread-count cotton (300TC+); however, ensure the supplier uses digital reactive printing to maintain the 3D depth on natural fibers. Always verify the fabric weight (GSM)—a range of 90-120 GSM is standard for durability and breathability.
