Synthesis Of HBP-TiO₂ Nanoparticles And Its Application For The Anti-UV Finishing Of Silk Fabric

This project explores a new synthesis of TiO₂ Nano-material and its modification method, this method is implemented by one-step synthesis and modification of amino-terminated hyperbranched polymers on nano-particles modified by modified Nano-TiO₂ which are prepared（HBP-TiO₂）. Empowering Nano TiO₂-rich active groups and explore content of deionized water, add glacial acetic acid, hydrolysis temperature and other conditions affecting synthesis of nanosized TiO₂ Nano-particle size. In success preparation amino of modified sex Nano TiO₂ particles of based Shang, this subject respectively using XRD, Nano Sizer, TEM, SEM, Raman spectrum, EDS and FT-IR technology on amino of modified before and after of nano particles for has rich and and detailed of characterization, Through characterization and optimization of Nano-particle performance indicators continuously optimized through characterization of nano-materials synthesis. Successful get a size of 15 nm Nano TiO₂ particles, and the particles show a good homogeneity and dispersion.Finally, this paper discusses the amino modification of nano TiO₂（HBP- TiO₂） and pure TiO₂ nano- finishing on the silk fabrics. The concentration of HBP-TiO₂, the concentration of HBP-NH2 and the temperature were discussed. Compare the before and after UV finishing silk fabric breathable performance. Experimental results show that when the concentration of HBP-TiO₂ nano was 5g /L, the concentration of HBP-NH2 was 10 g /L, measured silk fabric UPF value reached 80.3, 30 times after washing, the value of the UPF can still reach 62.5, while the same silk fabrics without modification under conditions of amino nano TiO₂, after finishing its UPF value of 48.6, measured 30 times after washing, the UPF value was 14.9, indicating that the amino modification nanosized TiO₂ after finishing on silk fabric, under these conditions, the permeability of silk fabric compared to the original permeability of 85.1%, but the anti- UV performance upgrade for the original 11 times.
