Nano-printed fabrics use nano-scale dyes or pigments, combined with high-precision digital printing technology, to give the fabric fine and realistic pattern expression and excellent color fastness, bright colors and washable and wear-resistant. Its printing layer is light and moisture-permeable, which does not affect the original tightness and quick-drying characteristics of polyester. At the same time, it can be combined with nanotechnology to achieve antibacterial, anti-UV and other additional functions. The fabric is both aesthetic and practical. It is suitable for high-end fashion, sportswear, home decoration and other fields. It is in line with the environmental protection trend. It is an innovative fabric with both a sense of technology and fashion.
