Abstract
Silk fabrics are modified by dyeing with natural indigo and ZnO nanoparticles coating to enhance functional textiles. Silk fabrics are coated with different weight of 1, 2, 3, and 4 g of ZnO nanoparticles. The properties of coated silk fabrics and color fastness of fabrics dyed were investigated. The FE-SEM and EDS results of the coated silk with ZnO nanoparticles were clearly confirmed the strongly adsorption bond of ZnO on the surface of silk adsorbent. Silk coated 3 g ZnO nanoparticles also provide optimal condition as the presence of Zn content on silk surface remain contain approximately 79.00, 76.84, and 75.95 wt%, which was slightly decreased after repeated 10, 20 and 30 washed cycles, respectively. Coated silk fabrics samples and indigo dyed exhibited excellent anti UV protection with UPF values in the range of 49.31 to 105.83. ZnO nanoparticles modified silk fabrics can be used for improved washing fastness of natural indigo dyed, UV protection, heat resistant, color fastness and durability of antibacterial.
