Application of photochromic yarn in the design of multi-layer woven fabric
In order to enrich the diversity of fabrics,the photochromic functional fabrics with"P"pattern were designed and developed by using photochromic yarn and combining the double-layer structure with surface and inner layer exchange.Furthermore,the photochromic functional fabrics with three layers of"E"pattern with the structure of changing layers in the upper and middle layers were designed and developed,which achieved the special effect of the fabric changing color on one side under light illumination,while the reverse side did not show discoloration.The combination of photochromic yarn and double-layer or multi-layer woven fabric with inner and outer layer change structure can form a new photochromic functional fabric,which provided a new idea for the development and design of such products.
