Abstract
The variety of colors in clothing is not satisfying the demand for textile performance. It is still a challenge to efficiently construct multifunctional colored cotton fabrics with durability. Here we report a convenient process to prepare multifunctional colored cotton fabrics with hydrophobic and UV resistant properties via self-curing raspberry-shaped colored nanospheres and PMHS. The synthesized silica/disperse dye nanospheres (SiO2@DPBA) effectively avoid the leakage of disperse dyes. SiO2@DPBA nanospheres with well monodispersity have excellent color performance that can be directly sprayed on cotton fabrics to obtain a good color depth. In order to further improve the color fastness and durability of cotton fabric, a transparent hydrophobic coating was constructed on the surface of the cotton fabric using PMHS. Ultimately, the colored cotton fabric achieved 140.2° hydrophobic angle and UPF value (200 + ), and exhibited good mechanical and chemical stability under various environmental conditions. Thus, the synergistic interaction of colored nanoparticles and PMHS provides an easy and feasible approach for the fabrication of multifunctional dyed textiles.
